Hi, I do pools for a living and wanted to know if this mask would block diatomaceous earth powder. Thanks in advance!

It should. I don't remember the particle size of DE of the top of my head. Oil based chemicals are about the only thing this doesn't filter when fitted properly. Check www.3M.com/PPESafety for more specific info

while I've never heard of using Kaolin clay in your garden (not saying you can't, I've just never heard of it), I do use diatomacious earth and it works wonders! It gets rid of all kinds of crawly things (including fleas if you have dogs). The stuff is magic! Just be SURE you purchase FOOD GRADE diatomacious earth, not the stuff used for pools. I do use Kaolin clay for cosmetics and clay masks, great stuff for that. Also, you can't go wrong with the Frontier brand. Love their products.

Hi. I went through the same thing and checked the 3M site. For the mask you may buy different kinds of filters. The one that is for dust, like for a woodworker, has a filter inside that looks like a cars air filter. The one for chemicals has a different filter inside and you may use these pre-filters. Put one of each cartridge facing up. They fit into the ridge around the filter and a cover keeps them in place. Hopefully I've been reasonably clear otherwise feel free to ping me again.

To keep dust and mold out of my system I used the pink circle filters (3M Tekk P100 Particulate Filter with Nuisance Level Organic Vapor Release) and it worked wonderfully--much better fitting and much better working than those disposable masks. If you have allergies or asthma or got really irritated lungs/nose/throat the last time, I would recommend this for the next time.Others have mentioned more detailed specs on the 3M website. (Your second question, I don't have a response for.)

Many pool professionals consider Diatomaceous Earth filtration to be the finest. This material acts as a sieve removing smaller particles than sand or cartridge filter systems. D.E. is a porous powder with microscopic openings, that when magnified look like tiny sponges. Clear water can pass through these openings, but particles as small as one to three microns (average grain of sand is 1000 microns) are trapped in the media. The powder is usually poured into a slurry inside the skimmer and then it coats the filter grids.Dosage: 1 pound per 5 square feet of filter area. Replace 1-2 times per year or as needed.

You can buy different filters that fit the mask. I have used the 3M 2091 in a dusty woodworking environment and have been very pleased with the results. Here is a blurb from the product sheet for the 2091 filter: "* OSHA substance specific particle exposures: - Lead -Asbestos -Cadmium -Arsenic - 4,4' Methylenedianiline (MDA)". Another filter is the 2097, which provides relief from particulates and organic vapors. Just do a Google search on 3M 2091 or 3M 2097, but it looks like you should be protected. I love my mask. Good luck.

Assuming that your fumes are organic vapors from diesel or gasoline--this should work just fine. This is also protect from any allergens from the lawn/grass cuttings. P100 filters protect from gas & vapors as well as from particulates, mold, bacteria. Great filter. Fits on both half mask and full face mask.

Well, I use it for sanding and carving gourds and those particles are 10x smaller than saw dust and it keeps me breathing clear. My guess would be yes. Bottom line is if you can still smell or taste what hazardous material you are working with then the mask is mot working.

I am wearing the mask to clean out a hoarder's residence - dust, mold, mildew and ofther fine airborne ickiness. I believe the mask is good for .01 microns. The manufacturer's website has the details. I have found the masks very effective. Initially it felt claustrophobic to wear, but I got used to it. I definitely notice a huge difference if I am in the environment without the mask. Track your wearing time - the filters are rated for about 40 hours use. I have found this to be fairly accurate.

Look for info on the particle size range of asbestos. I would think it's larger than the filtration ability of this cartridge; if it is, then you'll be protected. You probably already know this but the other important factor is taking the time to get a good snug fit. It doesn't take long but it's essential that you ensure it's snug all the way around every time you use it. I have used these cartridges with two different styles of mask (one protects my eyes as well) for years now and I always appreciate how much it protects me from even the obvious dust. I wouldn't be without mine.

I have been using it in a highly dusty atmosphere, a bathroom I am remodeling and had a lot of drywall dust, concrete dust, as well as regular dust that had been making me sick. I had sprayed the room repeatedly for termites and I think the poison mixed with the dust was the culprit. Using this mask, I was able to empty the room of junk(which covered me in dust) one day, prepare the room the next day, and finally vacuum and sponge mop the room the third day. The dust did not clog the mask at all and I had no reaction to the dust, all I had to do was shower after each days task was done. This mask performed perfectly for me and I'll continue to use it when I clean my old shop building this spring, using the same filters I'm quite certain.

it depends on which type of filter you get for the mask. There are different grades of filters that are intended for different purposes, depending on what type of work you are doing. There are filters you can buy that will filter out gases and lead particulate.

Yes the mask will keep out water from your eyes & nose. You will have to breath from your mouth

It's a really fine powder. Nix on tea ball. It will probably clog filter quickly.

This is only a N95 filter system. It will provide protection against 95% of the dust and particles. It's great for a dusty environment, sanding, light painting, etc. I would check to see how small the particles are for "lead fume" and see what type of respirator protection you would need before risking your health.

Not sure what mask you are talking about however, it will protect your face from flying debris. If the metal is super hot it may make a mark in shield but it shouldn't get through. I use mine for wood turning and have had huge chunks of wood fly off the lathe and hit the face shield. My face was fine but it did crack the clear shield part, which you can get replacements for.

This filter works fine for all of your dust and particulates. I would certainly change them out on a regular basis (perhaps 40 hours of exposure). However, there are better choices if you are dealing with ammonia or pesticides. Most pesticides you would probably use an organic vapor acid gas cartridge and then use a prefilter for the particulates. With ammonia, I believe that you can get an ammonia cartridge for your 3M mask and once again add a prefilter for the particulates. All this said, if particulates is the main problem, I would stick with the 3M 2097.
