Review on Respirator 3M 7502 size M, 1 pc. by Michal Wasowicz

The most comfortable mask in which I worked, does not press, does not rub thanks to convenient adjustment straps. Filters are expensive (¹/³ mask prices), but they fully justify their price, no odors, no dust penetration under the mask, breathing is easy. Installing pre-filters at a price of 100 per pair extends the life of the filters at least 5 times. In general, if you are constantly in rooms with odors and dust, I recommend this mask, it fully justifies its cost!
