12 PCS PM2.5 Activated Carbon Face Mask Filter for Adults, Replaceable Mouth Respirator Filter to Anti Haze Dustproof Air Pollution Germ

These filters in this day and time a must! Happy to receive them in a timely fashion. I have and will continue to purchase additional supply. Nicely manufactured.

Excellent value; each pair of filters come individually wrapped, which is more sanitary and I can dole them out to my children, one for current use and a spare. Fit perfectly in N95 masks, and add further protection in cloth masks. Very satisfied with purchase!

I tried one yesterday. I was impressed with how will it well it worked

I use these continuously because of health challenges. Two filters provide complete coverage in my masks.

These fit into all my masks with pockets for filters. They are lightweight and thin. Much better than I expected.
