Easy to breathe through

Easy to breathe through, and now that I see they are KN95s I am impressed. In that case I highly recommend them — I can run and easily continue to breathe with this on my face.

Satisfied Customer

The refill fits snugly in my ProSport mask. It was easy to breathe with the mask wi the masks on.

Love they’re reusable, sizing slightly off

I love that these are reusable filters for cotton masks. Used them for travel and highly recommend. Only annoyance is they are slightly shorter than I would prefer so they sometimes fold up inside your mask if one end slips out of the mask pockets. If they just made them 0.5-1” longer they would fit perfectly in the masks they sell!
