How fine a particle does it filter .

It is typical surgical mask to create barrier against bacteria and viruses.

It stirs the dirt up and sucks it through a fabric filter. I find that some particulates get through. The filters come in various capabilities so get the finest available, 2 microns.

easy enough to clean filter, however if you forget it could mess up the unit..it is really not meant for a dusty area...I used it while I was finishing the apartment I was building and the dust build up was considerable..i did clean it every day ...took out filter and vaccumed it..

the unit has air quality monitor, clean room mode, sensor for particle and dust. True HEPA filtration captures 99.97% of pollen, dust, pet dander, and smoke particles as small as 0.3 microns. *From the air that passes through the filter

It's a pretty good sized filter- basically the whole handle- and very fine. I don't think it will let any particulates through. I've had to pop it out and rinse it a couple of times when I noticed flow decreasing. It's very easy to do.

It depends on how much of the filter is covered. I change the filter before each time I use it.

This mask is sufficient for many different task. The filter is what dictates the appropriate safety. A pink n95 rated filter will handle particulates fine.

There is tradeoff between how much particles get filtered out and how much air gets through to your system. As much as it sound good to have EVERYTHING filtered out, that isn't necessary, and may strain your air system. A range of 7 to 12 is really good for a residence. More than that is for science labs, hospitals, etc. But whether to choose 7 (less filtration, more air through) or 12 (finer filtration), may depend on the age, condition and efficiency of your AC/heating system. An older system might be stressed by trying to pull air through a finer filter, or cost more to run the system because it has to work harder.

The filter will remove particulate matter. Ethanol should not have any effect.

Not at all. That's precisely what this kind of filter does. There will be no dust. Just make sure that you change the filter at least once a month.

It will filter just wont use the ionizer to make the dust particles stick together and clean at its most efficient capacity.

Sorry, it only takes out particles. If they are iron they will be held in filter, but the water will still flow over them.

Fairly tiny. The bottom catch filter is a tight mesh screen. So tiny enough for floaters you can see but not tiny like a fabric screen you see on robots.

I've had this filter for a few years and I just vacuum it out with my Miele hepa vacuum. No problems so far.

This respirator accepts a wide range of filters to address many environmental factors, from dust particles to pesticides. Choose the appropriate filter and pre-filters for your specific situation.

The filter is made of electrostatic paper used to capture dust more efficiently.

They filter particles as low as 4-5 microns. When I was in S. Korea I observed people wearing dust mask and these 3-M mask and filters are 1000 times better. Also the mask fits closer to the face with not gaps/openings.Loyd
