3M P100 / OV / AG Multi-Purpose Reusable Respirator 62023, Medium Size, NIOSH-APPROVED P100 / Organic Vapor / Acid Gas Rated Filters, Adjustable Head Straps, Comfortable & Lightweight (62023H1-DC)

I have MCS (Multiple Chemical Sensitivity) EHS (Electromagnetic Frequency Hypersensitivity), lead poisoning, Mold Sensitivity, etc. I use this mask and filters while mowing acres of grass on the farm since I react severely to exhaust fumes. I also use it when working in a moldy basement, spraying any chemicals, cleaning with chemicals, etc.This does a great job, but if you have a thin face like mine, and are moving around a lot, bending down, lifting, etc...then the mask will gap away from the face and allow some of the toxins to enter. It doesn't matter how tight it is adjusted to my face. My sensitivities are extreme, so if you don't have reactions as severe as mine, then you will probably be okay. If you have MCS, and are working real hard in it with a lot of movement, and your face is thin, then it might gap a little every now and then and allow toxins in.But...overall...this is a very good mask, and keeps out the majority of toxins. I've learned to replace the filters every 30 days, especially in the summer when I spend 6 hours per week mowing grass. If I am using it a lot...I replace even more often. If you begin to feel light headed, about ready to pass out, trouble thinking, etc...it is defiantly time to replace the filter. Just as a side not...I also take massive doses of vitamin C to help my immune system fight off the negative effects of toxins. Before mowing I take 6,000 MG of vitamin C (that is not a misprint...I take that much.). So with the mask and vitamin C, I can usually make it through most toxic jobs without to many negative side affects.I also use a marker and write the date that the filters are opened right on the cartridge, so that I know when to replace them. You should also store them in a zip lock bag when not in use to extend the life of the cartridges.

Great fit. Protected me from all kinds of stain, gas, and dust. Lightweight and smell proof!

Mmmm yes. This is a delight to own. It's extremely comfortable and it fits my face like a glove. I have a very small face and head, being 5' 4", 115 lbs. The medium is just right. It looks big when I wear it but it works perfectly. The way that its built is also worth mentioning and appreciating. It has a double head strap meaning two straps are connected to each other where one strap will sit on at top of your head and at the back at a 90 degree angle. The other strap located under the chin is like a belt that you clip on around your upper neck. Once these straps are fastened you get a complete seal over your mouth and nose. Also note that this is a P100, compared to the other one which is P95. The other one will only trap 95% of particles while this one traps 99.9%. I don't need the AG feature as I am using it only for sanding, painting, and finishing, however I bought this one over the P95 because I wanted 99.9% filtration. I would say this is an excellent product and I would highly recommend it.

Happy to receive the medium size respirator mask. Glad to see the safety seals on the box were fully intact. The face mask is light and fits perfectly for petite women. Worth the price to protect your lungs from a variety of particles Would highly recommend.

Had a bit of trouble getting the filter bits onto the mask, but it worked great once I got it together. I haven't died of mold poisoning yet.

Great fit and really blocks odors.

It's adjustable so it fit good nice and snug not too heavy I really like this mask

Got this to use with my airless paint sprayer. It was easy to assemble and does a really good job of filtering the air. It is more comfortable than I expected it to be. It's easy to test the seal and easy to put on and take off. Works great for my purpose and I believe you can use different filters for different needs. I like that the filters were included in the package as some of the others I looked at required that you buy the filters separately. I'm not sure how long the filter will last before I need to replace it, but I'm glad I can do that instead of having to buy a whole new set-up each time. I am an average-sized woman and the medium fits perfectly.
