Very easy to use this mask and filters
Seems good so far.
Arrived promptly and quality product
I bought the mask and extra filters as an alternative to flimsy paper masks and homemade ones made from socks (neither of which gives a close fit at the top of one’s nose). Used along with a plastic face shield, I think it will provide as much protection as is possible when away from home. For me, the best features of the mask are the ease of taking it off without the need to touch the front of it, and the fact that it is washable.
