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.
I have been in environments with these where insects are dying from the fumes (varnish/stain), and I can feel a slight tingling on my eyes from irritation, but with this mask on it's like breathing fresh air -no joke.
If you are using any kind of caustic substance in an enclosed area, you absolutely need a mask like this or you will be risking your life and at the very least brain cells.
My rule of thumb is if you know you're working with a caustic substance, and there is enough in the air that you can detect its smell, that you are inhaling that substance and damaging brain cells for no good reason, not if you have one of these babies!
Hope that helps!
I don't have trouble breathing when I'm wearing the mask, but my skin under the seal does get a little sweaty. Doesn't bother me, though. The medium size fits both my husband and I.
