You may be surprised how bad or how good your shop air is. I have two shop-made air filtration systems in my shop, and most of time, they are not needed when I use my SS PCS table saw and Kapex (because most dust is collected at source).
But some air quality monitors are sold dirt cheap online for $30 or $40 and, according to some YouTube reviews, they give you wrong results.
Without a monitor, you're pretty much flying blind as the most dangerous dust particles are smell-less and invisible.
ChuckS said:Yes, the AQM starts working as soon as you turn it on whether or not my woodworking session begins. It gives me the baseline as a start, good, air or poor depending on the air quality in my surrounding. We have had some really bad days due to wildfires in B.C. and Jasper, AB, and for occasions like those, I have a couple of box-fan turned air filtration units in the house to handle them when all the windows are closed.
This is not about "erring". Unless one is in a super-fine-dust-only setting, the preliminary filter is the one replaced regularly while the microfilter mostly based on when it starts to affect air volume.Cheese said:... with the main filter costing £187.21, a guy could error on replacing the preliminary filter more often to stave off the high cost of replacing the main filter.
I wonder if there is/will be a general rule of thumb for preliminary filter replacements per main filter replacement?

Let that sink in, people.
As [member=44099]Cheese[/member] also points out, an already-fleeced buyer will then be repeatedly fleeced every time a filter needs replacing. For Festool - this will be the gift which keeps on giving.
I’ve never used price as a yardstick - I’ve always looked at the value, with the best Festool example being my CT-VA-20. Very little material cost and a high price = but mine’s probably paid for itself twice over in bag savings. It’s always a balancing act for manufacturers and customers, and in the case of this, they’re having to price it based on recouping their development costs over a much smaller number of units since it’s a niche purchase. And for me - this tips the scales way too far since it doesn’t add enough value to justify itself. I’ll reluctantly pass. What a shame.
