Face Mask Filter (20 Pack) PM 2.5 Filter - Activated Carbon Filter Face Mask Refill - Size: Adult 4.75"X 3.15" | U.S. 1-3 Day Delivery

I ordered these face mask filters to use with face masks I had recently ordered from Amazon. A lot of the masks being sold recommended these filters for their products. I felt like with the Covid virus everywhere, why not take that extra step of safety with these filters. They fit perfectly in to the filter pocket on the inside of the masks and make me feel better having that little bit of extra prevention against the virus in place.

Great product. Fits in any type of mask.

Great price, no problem fitting filter into face mask. Filters came in nice size zip lock pouch to carry with you!

good
