Will this filter dust particles also? And if so, what's the rating?

These filters alone are not ideal for filtering dust particles. You will want to add a 3M 5P71PB1 particulate filter (with retainer) on top of the acid gas cartridge.

I remove the filter media and either blow the dust off using compressed air. Or, you can use a small, soft bristle, brush to,lightly, scrub the dust off. Perhaps a small, hand held, vacuum will suck the dust off. I haven't tried to wash it or rinse it off...that may work as well. Personally, I blow my debris off using compressed air at low pressure.

The product does not claim to remove dust particulates alone. However, if you watch one of their promo videos on you tube, they do claim the process increases the size of the particulates which allows your existing filter system to become more efficient.

It should. Most of these products actually work by make particles clump somewhat so they're easier to filter.

I haven't used it for that purpose, but I have used these filters in very dusty conditions while blowing out the interior of my garage and blowing leaves from my property. I've been using these filters since July and they have yet to show signs of needing replaced. They may not filter odors as well as they do particulates. The respirator they are attached to must also seal itself to your face without leaks for the filters to be effective.

It is not. HEPA filters are required to filter out 99.97% of particles 0.3 microns. This one can filter out 94% per Filtrete.

Not sure what you mean? Mine appears to be working as expected - still collecting dust per my black filter

I think so. One side is black (the side shown in the photo) and turns grayish whitish from dust, etc. as it filters the air that passes through it, as long as you insert the filter in the appropriate direction.

I think so, it traps the dust and would keep the more expensive filter cleaner. The pre-filter should be replaced once a year. It wasn't that difficult to replace.

Sorry, we have not put this vacuum in service yet. Don't know what filter you will need.

Sorry, I can't help with this. I returned the item due to poor performance and didn't have it long enough to have to clean the filter. Good luck.

I've used it for everything with no problem. Not using a filter and no problem. Just clean out dust bin.

Not really sure...I use Merv 13 4" AC Filters and they do a very good job at that...I did not notice any difference in regards to dust/particulates....

The filter is fine. It catches anything you can see. When I am sweeping and see dust floating in a shaft of sunlight, I put the air filter in the room, turn it on full blast and come back 10 minutes later. The air is clear. Nothing floating in the sunlight.

I have only used it to blow debris and dust out of filters, etc., but I believe it would work. I have liked mine.

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..

Yes, this is the "pre" filter that takes a lot of dust, etc. out of the air. It makes the hepa filter last longer.
