Hi there -

I am a proud owner of many Festools (and countless accessories) and appreciate their amazing ability in dust extraction when compared to competing mobile tools.  Disclaimer, I am a Festool FAN (Maybe one could even class me as fanboy---I'm that enthusiastic about these great tools).

There may only be one competitor that even comes close in tool features/quality/performance but you would have to put additional cost and lack of customer service from that competitor aside to make a fair comparison of offerings where both companies produce the same specific type of tool.  Festool makes high end mobile woodworking tools; there is no question of that; and that is not what this thread is about.

To qualify me as a person heavily invested in Festools looking to get the most out of them and also looking to ensure I am working in a safe environment when I use them in my garage shop I'm providing a list of tools and accessories I have from Festool (not definitive by any means) which I hope will provide insight into my setup to help others provide advice on how to create a safe environment  (I am not listing these tools to gloat over my fancy smancy mobile woodworking tool collection):

OF2200, OF1010, Kapex, MFT-3 full, Kapex MFT table, all track sizes, LR32 system, T75, CT36AC, BoomArm with AS hose and wire on it, Workcenter attached to CT36 vac, Several hoses most of which are 36mm dia and one 2 foot whip with 27mm for connecting to tools with smaller port, 300Jig, 150/3, 150RO, Domino sets small and large, 3Sysports and just about every accessory to go with them.  Great for field work, much safer than alternatives; and for a hobbyist with a few pro jobs here and there FUN TO USE (Because they are relatively simple to move/setup and spend less time cleaning up than with other mobile tools).

Being this heavily invested (and for those of you looking to get heavily invested), I feel I deserve to know definitively whether these tools will perform acceptably with regards to air quality as it relates to health in an enclosed area and are for that variable alone.

I'm talking about  working indoors in an en-closed area.

I'm talking about comparing to a woodworking shop rigged with larger high end dust collection systems (such as those offered by Oneida and Clearvue) and their stationary woodworking tool counterparts (bandsaws, table saws, sanding belt machines, planers, jointers and the like---some functions of which might be duplicated using Festools some of which cannot).  I'm showing good air quality when using stationary tools and a proper dust collector with the cyclone setup etc at the shops I've visited---though I'm not entirey sure there isn't something invisible going on in those shops, I've read that they can be setup to work safely and it has been proven with air quality readers etc etc.  So stationary machine setups can work with safe clean air shops....can Festools do this alone?

Now my current main goal is to build my garage shop with SAFETY top priority and I'm just wondering if I need these all of the typical large stationary tools when I seem to get some of the woodworking tasks done just fine with my Festools and a few hand tools....work getting done in a timely manner is a priority and so are cost and space but my lung Health and the lung health of those around me are my TOP PRIORITY.  This is why I'm one of Festools biggest fans---it seems to me that they offer a great combination with added benefit of being mobile.  If it is true I can replace some of the larger stationary tools with Festools without negatively impacting the safety of my garage shop when compared to stationary large tools and heavy duty dust collectors...well, then I'll have a big smile on my face.  If you provide some means of proof that this is true (a document of air quality in the area around the tools both during and after), photos of air quaility test readers, videos etc, 3rd party testing or anything else, well, then ...I'll do jumping jacks as I'll know for sure I don't have to buy ALL of the big stationary machines especially when some of the same woodworking functions I can get by with my Festools on.

I just don't want to put money/effort into testing tools and techniques...I want someone...the vendor or pro user, to do that for me and provide me with the stats.  Hopefully not to much to ask---peace of mind knowing air quality is safe in shop when using Festool...and something to back that up that has science behind it.

Air quality comes into play at the top of the list on the Safety checklist for me (I can lose an eye, I can lose a finger, I can lose my hearing, all of which allow me to continue living...but if I lose my lungs, I am a goner---imagine that is the same case for you too!) and air quality for me seems to be the most troublesome to quantify not having equipment or definitive information. 

I.e. where does it say in writing that if I use a Festool with their Festool vac, indoors, on their own I would have SAFE air quality?  It was just an assumption on my part, and I don't care to assume now that I'm contemplating making most of my work indoors in my garage shop; I need to know for sure.

Have seen several posts on this site asking how to improve dust extraction on Festools such as the Festool tracksaws and Kapex but haven't yet seen anyone get out their Dylos and report on whether bringing these tools into the shop without any other dust collection or air cleaning is SAFE and reporting statics per tool.

Is it safe?

Are Festools safe to use in a shop?  Are some safe and others not? That is the top level question...and then, if they aren't safe is there anything that I can do to make the air safe and continue using solely Festool in the shop?

I'm posting it here so that Festool representatives have the opportunity to respond as well as Festool users/owners.

Maybe there are modifications that need/can to be done and Festool doesn't have the answer but a user does---it may not be a Festool condoned modification but I'd still like to know because I can make that determination myself to some extent...and my biggest priority again is SAFE AIR.

TOP LEVEL QUESTIONS #1
At a top level, using ONLY Festool products out of the box without modifications, are we safe air quality wise to use Festools in a shop environment, out of the box and on their own?

I'm not talking about slipping over thicker dust and chips that might be on the floor but specifically looking at fine dust in the air both during shop-work and well after we've left (if the shop is like many of our garages being a shared space with laundry machines and the like)----when I leave, are my wife and children safe to come into the shop and use it outside of woodworking for long periods of time---without kicking up fine dust from my Festool woodworking and getting them unnecessarily exposed?).

I'm also not concerned with whether a competitor's tool is better than Festool or not in dust extraction...though you can chime in on that note, please don't HIJACK the thread talking about compatible tools from a competitor or how other tools don't have dust extraction at all.  Drop a link and line describing and pipe down, we can judge from there about other competitors...or you can start your own thread even better; I'll see it :)

I just want to know if Festool dust extraction by itself is good enough to be used in a safe working/living co environment.  I'm selfish that way being an owner of many Festools and don't want to get off topic.

Let's take a walk through some common Festools and see if any fair better than others from my limited observations with regards to visible dust collection:

Sanders
The sanding tools don't seem to put any VISIBLE dust in the air---at least not as much as those wanna be dust bag extractors on other sanders I've used in the past (Dewalt/Craftsman/Bosch...all put CLOUDS of dust in the air)---I'm hoping the fine dust also goes wherever that VISIBLE dust must be going and enough so that it is safe to use the sanders with my Festool system in the shop.  Please confirm.
Tips:  The sanders DO leave residue dust on the work-piece and they should be either wiped down if not for your health at least for the quality of your finish... with your preferred method (I don't use tackcloth as that can mess up some finishes), blown off outside (rather inconvenient on a rainy day), or vacuumed over further with a natural bristle dust brush on your collector at high setting...in addition to wiping down with a clean shop towel and tossing or cloth that doesn't leave behind fiber and shaking out outside I would imagine can't HURT the quality of the air...and downright might be necessary to keep healthy air in the shop.

Jigsaw
The JIGSAW leaves visible dust and small chips all over the place (It is the best dust collection Jigsaw out there and this is an inherent problem with Jigsaws; no fault on Festool here).  I'm thinking there is some invisible dust getting out into the shop here as there is just so much VISIBLE dust getting out.  I'm guessing some kind of modification setup has to be used to get safe air? and it will involve a high power stationary dust collector?  Correct me if I'm wrong, I'll do a backflip if I can just use the Jig as is and all fine dust is captured and I'm wrong. My current feeling is this tool might be best used outside only...without any air quality reader gadgets to confirm that feeling or not.

Kapex
I have a Kapex, 5 foot 36mm hose (yes, I've already shortened the hose ---the only Festool I've made a mod on to better dust extraction according to advice/information posted on this website from users... changing my hose length appeared to be a perfectly safe modification) connected to a Festool 36 AC extractor and it get's MOST of the VISIBLE dust out of the box on through cuts.  I'm guessing that by the blade speed and how fast the dust is shot out, that I'm not collecting enough fine dust to be safe in the shop.  This tool being used in the shop most likely needs an appropriate hood and high power stationary collector hooked up as well to be safe in a shop environment; though I could be mistaken...correct me if I am wrong.
Creating a 0 clearance insert was another suggestion, which I haven't done and I expect that will help but not eliminate the dust getting out.  I don't care if its just thick dust that falls to the floor, but if thin dust is getting out...without a separate air cleaning tool, enough so that with typical hobby use I will destroy my own lungs, then I just need to know.

T75 Track Saw
T75 on my 11 foot 36mm AS hose that came with CT36 AC (auto-clean) which is a black hose designed for the planex---its on boom arm and am using an MFT table.  It gets MOST of the VISIBLE dust out of the box without mods on through cuts, but MODERATE amount of VISIBLE dust on thinner edge cuts.  We cut edge cuts ALL day don't we?  There are mods suggesting covering the hole (Festools official position I'm guessing is not to do that as any mod to the Festool machine frame could reduce the safety of the tool if it should for instance come loose and get caught in the blade...they can't possibly condone a 3rd party addon here I don't think), putting a piece of wood to accept the front of the saw at the end of the cut (where a lot of the dust seems to be going) and some are already suggesting putting a stationary dust collection system setup to create a hood around the work area to capture dust at end of cut (though this still doesn't fully address what might be shot out of the sides).  I'm guessing fine dust is getting out with this visible dust and floats in the air.  Most of the work is done here using this tool so that should be taken into consideration...a little dust a cut but a LOT of cuts could be making my shop air unsafe now and into the future without separate tools to help clean the air.

Routers
Visible dust gets out.  I'm not sure if any fine dust is getting out in sufficient quantities.  Again I'm guessing but I think that a separate dust collector hood for the work area is needed.  An inherent problem with all plunge routers...again I think Festool is doing the best job so far but I don't want to put that point ahead of the fact that it is or is not safe to use...even if it is the best.

Domino
Barely any visible dust get's out of these things ever.  I'm guessing nothing needs to be done to improve dust collection here...though I'm wondering if a 36mm port instead of the 27 should come on the Domino and if that would help eliminate all.  A good downdraft table underneath the work area would fully set my mind at ease though...let me know if you think that is entirely NOT necessary.

There are recommendations on this forum to modify these tools.  If I didn't capture them, please do fill me in.

To recap.  I'm HAPPY with my Festools!  I plan on using them a ton.  I bought them under the premise that they have EXCELLENT dust extraction qualities and that is true as far as I can tell.  I did not however consider whether they were performing extraction so that they were providing 100% SAFE air in an enclosed environment without using some other branded tools/setup to help.

I'm wondering if we can get some answers here on whether I can rely on using them as my main shop tools as a hobbyist in my shop as is, or if in fact I will need to do something with other brand tools to get my air quality up to par while using in shop;or and I hope this isn't the case....that it is known that these tools CANNOT be used in an enclosed environment safely even with some steadfast modifications that are safe and approved and documented by Festool.

Please let me know your thoughts-

Christopher,

I am totally satisfied with my Festool dust collection for my Sanders, Domino joiners and Jig Saw.  I did add the Oneida Ultimate Dust Deputy to save on Festool Bags.

In my garage shop, I have a 8" Jointer, Cabinet Table Saw, 12" planer, 20" Bandsaw, Shaper, Drill Press and several routers so I use the Oneida 3hp V-System to prepare my wood before finishing with my Festool tools and dust collector.

Christopher thanks for posting this, I've been wondering the exact same thing and would like to add my two cents.

I read some Bill Pentz material on super fine dust and am now taking the lung damage topic very seriously.
I'm sure I've screwed up my lungs by now from being lazy about super fine dust in the past.
Plus I have serious sinus problems so shouldn't actually be around sawdust any more at all (too bad Festool makes woodworking so fun.... [big grin])
I have no answers for you but will just list what I've done myself so far, on a small budget, and see if anyone on the forum who has advanced knowledge on the topic has any comments...

Not worried about chips here, ONLY the super fine low micron dust that is a serious respiratory hazard.
The stuff that stays airborne for days so as to become, in effect, a permanent air problem.
I'm in a small garage space, recently set up with the goal of only using Festool tools and no freestanding machines, specifically to make cabinets/casework, little/no solid wood furniture.

CT MINI, used always, on hi with the saw, adjusted down for sanding.
3M 6000 series half face respirator with N95 or P100 dust filters. I wear it about 90% of the time.
Austin Air Health Mate Jr., a fine dust/HEPA air filter, turned on all night.

Also storing all items in closed base cabinets, or systainers, so as to provide few out of the way horizontal surfaces for the super fine dust to hide and then get stirred up again later.
Floor and work tops get vacuumed.
I vac most workpieces after sanding too.

Seems to work extremely well, but have no was of testing/verifying this. I'm just shooting in the dark basically...

 
Im happ with my festool dust collection to. i work in a garage and when its cool I close it up no problems. What I do recommend is a air filter. I have a older version of this one,

http://www.amazon.com/708620B-AFS-1000B-Filtration-Electrostatic-Pre-Filter/dp/B00004R9LO/ref=sr_1_sc_1?ie=UTF8&qid=1361502836&sr=8-1-spell&keywords=jet+air+ourifiers

I use it along with my festools. 

One thing I can say is after buying festool products ( Im in the process of going to almost a entire festool shop)  I dont see the dust lying on the tools and cabinets when I walk in the shop the morning after work all day the previous day in the shop.
 
While I have no scientific data, I would not work in a closed in shop (like my own) without air filtration units like Sancho57 recommended. 

  If you happen to do any cutting (ts55, Kapex) next to a window with strong sunlight coming through, you will see what looks like a lot of very fine dust going into the air which without the light would not be seen.  I don't think it is a large volume of dust at all but it is very fine and airborne.

 
My garage has big garage doors in the front and back, so in good weather I can get some pretty good ventilation going.  Even if it's raining, as long as it's not too windy, I can keep them open.  I have a Clearvue cyclone for my big tools, and a CT22 for the Festools.  I figured I was covered.  I bought a Dylos monitor and put it out in the garage.  I was depressed when the values read about 1000 (I think that's in the fair to poor range).  That was with nothing going on and the doors closed.  I opened the doors and the value jumped to 4000 (higher numbers are worse).  So much for fresh air.

Anyways, I noticed the numbers went up as I did anything in the garage - anything from walking around to ripping sheets of ply.  Ok, no surprise there, but at least it made sense.  In general, the Festools don't really cause the numbers to spike too badly, but if the garage doors are closed and I'm doing a lot of sawing (TS55 or Kapex), it can get up to around 8000 - that's the point when I can feel it.  It's break time then.  Other tool use won't get it so high (that I can recall - I haven't been keeping records on any of this).  With doors open, the numbers are typically just outside air numbers - between 2000 and 4000, with a little increase when sawing or doing anything.

I revived my old Delta air filter (similar to the Jet) and bought new filters from Wynn for it.  That runs almost constantly out in the garage these days.  Now when I walk out there, the numbers are down under 300.  Sometimes as low as double digits, just depends on the day.  A lot of cutting in a short amount of time will still drive the numbers up to around 8000, but they come down under 1000 very quickly with the air filter going.

If I'm going at a slow pace, the CT22 and Delta filter seem to keep the numbers between 1000 and 2000.

Interestingly enough, if I do some spray finish in the backyard (and this can be about 50 feet from the garage door - nowhere near the monitor) I'll see numbers around 20,000 to 30,000 inside the garage.  Yikes.  That goes away quickly.

The numbers I'm listing above are from my Dylos 1100 Pro, which displays two numbers - one for particles between .5 and 2.5 microns, and another for particles larger than that.  I listed the numbers for the smaller particles.  According to the label on the back of my Dylos, anything over 3000 is very poor air quality.  But considering that outside air is often above that level, I'm not really sure how to feel.

Most of my power tools are Festools, but I've used other types of power tools at local workshops, and I can feel it in my lungs at those other (non-Festool) workshops almost instantly.  I'm way happier with my Festools, but I know they're not perfect at catching the dust, and I've seen the numbers.  I haven't implemented all the suggestions to keep dust down, but I use my CT22 with everything all the time unless I'm sanding or cutting outside for just a little bit and don't want to hassle with hauling the CT22 out.  Anyways, there's a little info regarding air quality.  Sorry it's not very scientific.
 
I had the same concerns as the OP.  Festool is known for excellent dust collection, and their tools clearly are better than most others, but I didn't know what that meant, really.  So I started a thread elsewhere (called something like Dylos Data points) where I reported deltas in my Dylos readings before and after running my Festools.  My intention was to compare a bunch of my tools, but life got in the way.  The results were that fine particulate counts spiked almost immediately after turning my sander on and letting it hit wood. 

For anyone concerned about exposure to known carcinogens (wood dust) of exactly the right size to cause various cancers, this was a concern for me (and why anyone would not take this seriously, I have no idea).  In another forum I used to read, I got in an exchange with someone who (amidst a bevy of contradictions) claimed that hobbyist exposure cannot cause cancer.  I've worked for over a decade in cancer research (almost a decade in computational science at a top cancer institute and am now in clinical research for cancer) and I know better.

Anyways, I'm sure this thread will be joined shortly by people like the one I described who will tell you to put away your particulate counter and forget about it.  I say those of us  who want to understand what their exposure is - thereby enabling one to do something to mitigate it - should start reporting this data systematically.  You can't control something like this without first being able to measure it. I'm thinking of a thread where people run their tools with a counter in a semi-standardized way (e.g. particulate counter some known distance away from the tool, in some specified orientation) and reporting before- and after counts, or better, displaying graphs of the particulate counts.  While the absolute numbers do not matter, it is the deltas or differences before and after that will be telling.  Then one would have a basis for understanding what usage of tools - Festool or not - involves, exactly what the value proposition of Festool dust collection amounts to esp. compared to other tools, etc.  Then various abatement measures (filters, etc) could be assessed.

That was the intention of my original thread, but like I said - life got in the way.  If anyone is interested, I do have a bunch of stuff and I would be willing to resurrect the project.
 
I am definitely interested in your independent study and figures; this is very important to me.  If you do confirm your preliminary findings, I would be even happier if you showed me a way to reduce risk completely using whatever method is needed.

Not every woodworker is going to need this information, but in my case with my solid wood woodworking tasks (multitude of dangerous species of wood in enclosed garage shop) it will be particularly useful to understand the extent of the exposure using just Festools and different methods with which to attempt to mitigate  that exposure.

Basically so far I`ve not seen any data to tell me that I should NOT be concerned with an all Festool setup.  It appears to me that there indeed need to be other branded tools to assist in fine dust removal for safe levels while working indoors.  In the case of the fella with the double garage doors, he points out that fresh air alone has a high count ... I too think that may not be as important as knowing that particle counts go up because of WOOD dust which can be toxic vs. whatever other particulates may be found outside that may be in high counts but potentially NOT as toxic as wood dust.

Preliminary ideas to mitigate exposure to fine dust caused by using Festool tools without any other branded tools.

Powerful Dust collectors
Dust hoods hooked up to large efficient stationary collectors  (may have to develop a custom never before seen hood for track saw).

Overhead air cleaners
Air filtration unit like the overhead Jets (which sound like they clean the air sometime after you may have had exposure---so if they do in fact clean the air satisfactorily, a mask must be worn until the unit has had time to clean the air).  If you work in the shop with this as your only method of air cleaning outside of those available by Festool, you would probably want to take other precautions like not returning through garage door directly to house, and beating dust off clothes outside, to mitigate exposure to family, especially young children.

Working outside.

Combination of some of these.

Anything else?

I'm not sure I'm to keen on using my track saw indoors in place of a table saw with powerful collector hooked up at this point.

I was initially thinking that would be possible.  Matter of fact I'm wondering if its a good idea to use any of the Festools inside without some other assistance from non-Festools...

Shane do you know if Festool has any studies on whether the tools can be used indoors safely in a shop setting with regards to fin wood dustand whether they have any recommendations official or not.

Thanks for all the good info above.

One item to add here I read about elsewhere is the superfine dust accumulating in the house, in the case of garage woodshops.
In theory, you really are being effective by wearing the 3M respirator, properly fitted, w/ 95 or 100 filters on it, or a similar industrial grade product. (Plus, these are lightweight and only cost 20 bucks!)
But even with this approach, you then have the dangerous low micron particulates that make their way into the house and stay airborne, that you and family are then breathing, 24/7.
Would it not be useful to use the Dylos in the house as well?

Hmm. Maybe ditch the sanders for a scraper?? [eek]
 
I have a Racal/3M " Breathe easy 1" system I bought over 20 years ago when I sandblasted & painted.  I still use it when I mow the yard because it is hepa dust free and you don't smell the grass (or anything else) at all.  With this system I'm pretty sure one would not need to worry about exposure dust of any kind. Just something you might consider.
 
I would be interested in the Festool US official answer to this.

I agree with most of the remarks above and have noticed how much better things are since I bought into Festool.

I would think that the Festool US line would have to specify a particular extractor with a particular tool and so it could be a matrix of answers.

I usually stay clear of these threads... mainly due to the blowback from the person smokin 3 packs a day, and jumps in, calling us all crazy....  :-)

However,  I respect you trying to safe guard your health...I am the same way...and I have traveled down this road, similar to a few other posters above. 

I own a lot of Festools, but am not a fanboy...Love their tools, love the company, but I always remain objective about everything. 

A few points u should be aware of, this is based on my research 5 years ago on this same topic... pls don't ask for links and references, I barely have time to write this response...

unfortunately, its the ultra fine dust particles that have recently proven to be the culprit...
 
JSands, great info for this thread, thanks very much.
Lacking a single answer on this complex issue, it would be a great benefit to have a widely available "best practices" list on this topic, with a primer based on the dangers of >10micron particles.
 
Thx for kind words Panel....
as for your issue regarding dust in the house...  another great use for the Dylos btw.... this will only occur if you keep doors open, or, have a neg. air pressure in the house, pulling air from the ww shop into the house.  For example, a furnace in the ww shop that feeds the house, can pull dusty air from the ww shop into the house.  This can occur for many reasons, which is beyond the scope of this thread....a simple check..by some smoke generators (low cost versions, such as large match stick type) and watch the direction of the smoke during your operations...see if any of the smoke is entering the HVAC system (if in the ww shop) or through doors or windows.

I mentioned above, the IDEAL dust collection system in a fixed shop (obviously not on a job site) is to dump the exhaust air outside, forget trying to filter it.  An analogy, reminds me of stronger filters on cigarettes...it makes more sense not too inhale the smoke :-).    The reality is, trying to trap the ultra fine dust particles is VERY costly, takes up a lot of space, is very costly with large filters that must be monitored and replaced often.....and, a HUGE nrg drain, (try putting an ammeter on the motor to witness this)... as the finer the filtration, the increased amperage on the motor, and the obvious....much reduced suction on the intake.  This is the beauty of exhausting the sub micron particles outside after a cyclone has captured all the larger, "visible" dust. 

For those who work in very cold climates, there is good, albeit costly upfront solution to the heating bill...    ERV's, Energy Recovery Ventilators...their function is to bring in fresh outside air and capture approx. 80% of the nrg in the exhaust air stream.  Although they are designed for interior spaces, they can easily be modified with some basic HVAC knowledge to perform the same task in a small ww shop.  They are very effective, I have designed and built this one below for my house....nrg recovery very close to the 80% the manufacturer specs, and the house does not have an ounce of dust, and carbon dioxide levels in the house at most are 10% greater than outdoor air, about 500 ppm.  Prior to the installation of this Whole House Ventilator (ERV), inside spaces during cold months, or very hot months, would have carbon dioxide levels of > 2,000 ppm, and trust me, humans react to their own toxic exhale waste, hence why their is OSHA standards in commercial buildings for outside ventilation exchange rates.    Anyway, the premise is the same, remove, or greatly dilute the polluted air with fresh outside air, regardless of the type of airborne toxin.  These comments of course, are directed towards the home shop, not a commercial operation, which must meet codes not subjected to garage warriors....  For those interested, here the unit I installed in my house, a low budget installation, but highly effective, used mostly dust collection fittings to control what zones received the outside air... not required in a wood shop, or in most homes, as you can simply integrate the ERV into the homes central HVAC system...

There's a picture in the last post, James... no need to "read the articles"

j/k... very interesting thread
 
Well....I'm continuing my journey (albeit somewhat in the dark) with the assumption that MORE is better (MORE air quality safety) without knowing for sure but just based on what people have written here and what I have read elsewhere.

Apologies in advance for the length...I'm also including a LOT on shop setup here for the Festool in shop enthusiasts as I think others might find it interesting.  There are some elements here that shine light into my efforts to setup my fully functioning hobby shop heavily reliant on Festools.

Dust extraction after all is the first thing to keep in mind for shop setup in my opinion...yah, I'm spending about 99% of my time now getting air quality research and building around that but woodworking can wait until I have a safe shop :(

When all is said and done, I might be a few tables and chairs behind, but I will be able to sleep better at night and potentially live longer and healthier (My family too).

With no information readily available to help me confirm that I am SAFE using Festool system in enclosed environment (hand tools also are on my mind, if I sand a little by hand, or let dust off using some other tools somehow), I'm forced to be an air quality OVERACHIEVER.  (Well most of their vacs are HEPA certified with HEPA filters so there is SOME documentation...and I've read somewhere that they are the only authorized tool for some boat cleaning...but that doesn't cover what I'm talking about and I'm digging and not finding what I need).

I've purchased an in shop type air scrubber(used) (JET AFS-2000JET AFS-2000) and a (MERV 14)  upgraded filter (its the best I could find for the unit as Wynn doesn't make a filter for this larger Jest scrubber model).

These extra purchases and all of this extra effort is JUST IN CASE it can help with any fine dust my Festools system might be inevitably letting into the air that could be unsafe to myself and family (some arbitrary tests from users posting in this thread and elsewhere indicated there MAY be some risk----without officially qualifying that risk or not I'm taking action, still waiting on the official answer from Festool or at least some acknowledgment that they will potentially post some testing results for their tools with respect to air quality in an enclosed shop setting while using their system of tools (especially interested in Track Saw results as I'm having trouble mitigating the visible dust from that tool with my table design).

The air scrubber I purchased used for $200 and spent 15 minutes vacuuming it clean (with my Festool Vac and HEPA filter O_o) as a lot of dust had accumulated inside the unit despite the filters (that I've thrown away)---who knows what the prior owner was cutting but it could very well have been very toxic wood or worse;---I did this before bringing into the garage and used facemask with P100 filters...yes...I am an air quality FREAK right now.

It will be a tricky install to fit between rafters of my garage but I'm 75% of the way there... with purchasing mounting hardware (Chains/Ibolts and the like).  Mounting it on one side of the garage as opposed to the middle as I read somewhere this will help create a good cleaning current of air in the shop (though the articles also had examples where two scrubbers were used as opposed to one).  When the garage door is open the vent will point outside; maybe this will help as the cross wind usually is perpendicular to the garage door face/plane and should at the very least allow the scrubber to blow dirty air out of my garage and into the cross-wind.

So for ~$235 (Scrubber,NewInnerFilter,MountingHardware) + labor I can SUPPOSEDLY clean ambient air in the garage (when closed to outside and house) of any fine harmful wood dust particulates that might have escaped from Festool system within 15 minutes or less after I've powered down for the night---and SUPPOSEDLY protect myself and my family from exposure after the tools have been turned off and set down.  I say supposedly because I'm not sure how confident I am in the filter and filter system of these scrubbers (they are not HEPA compliant), but from what others have tested with their Dylos when reading small particle count and using what I assume is the default filter (Jet couldn't give me a MERV rating which is why I purchased elsewhere by the way---they said it is a 1micron filter....which doesn't translate into anything I can rely on to capture small dust) from Jet on a smaller Jet unit, I'm guessing I'll be getting similar results or better.  The Jet branded inner filter also was much more than $14 and it only had 3 bags whereas the filter I purchased (Actually hoping it will fit good; the nominal measurements were the same) had 8 bags (much more surface area).

Next on the list is moving my water heater outside (in a proper enclosure) as I'm afraid to suck any carbon monoxide back down the water heater vent now that I have significant air moving in the shop (even if I'm not venting outside with the scrubber I'm worried as I'm moving a lot of air now and with future plans to vent stationary outside, this will just grown more worrisome).

And of course, I'm going to look into a stationary dust collection system; so far it looks like Oneida will get my purchase; ClearVue just looks to hoky though I like their use of double filters it won't fit by default under my covered area on side of house.

I live in San Diego and even though I have an AC/heater unit in the shop the weather is good enough for most of the year to where venting outside won't cause me to lose any desirable temperature I hope.

The stationary collector will be used for my recently aquired Laguna HD16 used bandsaw mainly ,I say mainly as I don't have any other big stationary tools yet and hoping I can get by without them (A Dewalt 735 planer un-openened and am considering selling and upgrading as the integrated blower may not be ideal ---it doesn't appear designed for stationary dust collection hookup---maybe a mobile tool to go along with what Festool might be catering to).

I may also figure out how to incorporate the more powerful stationary collector system it into my predominantly Festool future shop plans.

Another project I'm working on is building Guid Henn's Multi-Function Workbench (MFW) Guido Henn's Multi Function Workbench using plans featured in Holzwerken magazine (Issues#37 & #38) and I'm looking at adding some downdraft elements into the table top to help with dust collection at the source...possibly some smaller pegboard like hole grids close to the tracksaw cut line....won't be hard to do as I'm having the table CNC'd (after some modifications to the original plans including both horizontal and vertical TS cut lines as well as smaller holes (20mm) so I can use Festool rather than Veritas dogs/elements).

Wouldn't that be great to be using Festools ontop of a table with powerful downdraft? (funny thing is when I first saw the MFT holes I thought that is what it was for...downdraft!---1 year later, and I'm going to leverage holes in the table for just such a thing).

Using handtools for finishing the work, instead of brushing dust/ribbons of wood onto floor, just brushing into holes (or not having to brush at all if the downdraft is powerful enough).

I'm trying NOT to purchase a jointer (Going to try and see if I can get by with a Planer Sledplaner sled when needing to join rough lumber...most lumber I see myself using from my local suppliers comes with a jointed face already, sometimes 3s).  The joiner takes up valuable space.  If I do go with a joiner in the end, it will be a combo planer model and that Dewalt or whatever replaced it will go to.

I'm reluctant to by a Dylos as that money can be put towards woodworking tools...but I may just bend and get one later to make sure everything is working as it needs to...(or not and I just quit woodworking in my shop and selloff or something equally drastic like starting all over with stationary tool shop design)---get that table saw that I'm trying to avoid (they just aren't SAFE and take up WAY to much space).

I don't think I will use my Festools much without a mask for now, even with the scrubber working overhead...just to be extra safe.

I'm also still worried about opening the door to the house---even with the air scrubbed...but a little less worried...as I continue to build the shop out I hope that worry get's less and less.

If you live near San Diego, and want to stop by with your Dylos, PM me!!!!

There will be another thread covering my mainly Festool shop design in the future---hopefully as long winded as this thread! :)
