Vac filters.

When changing  the bag on my midi today I was inspecting the filter and it got me thinking.

The filler level oks identicak to a typical automotive air filter. Anyone ever check if one of the automotive filters would fit for 1/10 of the cost?

I suppose for some uses it might be ok, but not if you are looking / needing / wanting for a HEPA filter.

As soon as you know what filter fits a hepa version should only be some telephone calls / mails away - as you then can easily find out which company make these it's straightforward to ask them them directly 'is #xxxx available as hepa?'.

Would be interested to find out what filter (car make/model/application) is mechanically compatible.

Just wondering if the restriction would be the same?  If Not same, would it matter?

I wouldn’t want to be caught on-site vacuuming up asbestos materials without the correct HEPA filter.
If an inspector catches you violating the Clean Air Act, it’s a $250,000 fine with jail time.  [eek]

Admittedly there are times that a heap filter might not be necessary in my world, but I've only replaced my CT-22 filter one time in 9 or 10 years.  And that was primarily caused by using the old style paper bags that punctured in my usage.  I will personally just stick with the hepa filters.

I thought HEPA was not adequate for asbestos.  Pretty sure I read that numerous times including being said by Festool also.

There's higher grades of filtration than HEPA.  Some are are used in hospital settings, although I'm not certain those even conform to asbestos extractionl

I’m not a contractor but according to my friends that are, HEPA filtration is required for local asbestos abatement. I wouldn’t doubt that in the future higher standards will be enacted and with that comes more expense.

I was also employed by several semiconductor manufacturers for 30+ years and there are certainly higher levels of HEPA available. The most interesting take-away is that the dirtiest semiconductor clean room is 10 times cleaner than a hospital.  [eek]
That’s a scary thing.

Yes, but for finer filtration you'll have to cascade them coarse to fine (else the finer filters would clog too quickly).

Thats a scary thing.

I had some beers with a hearth surgeon once, he told me that he would rather have open hearth surgery on a glade in the woods than in a hospital OR - as the former has a way lower (basically zero) chance to contract a multiresistent bug, thus there's always a working antibiotic for anything you yould pick up there at hand.

That perspective was even more scary.
