PM2.5 Filter Refill for Face Masks

Great filters!

I bought this refill of filters because I had bought some Hang masks. The masks are wonderful! I have a small face and with the wire around the nose, the pocket for a filter and the adjustable ear-thingies - the Hang masks are a perfect fit!

Mask is better with the filter

Hang masks have been my choice since 2020 because of the fit and especially with the addition of the PM2.5 filter. The disposable insert improves the mask's filtration effectiveness against the smallest aerosolized particles.

I feel safer

These filters have 5 layers so I feel safer than just wearing a cloth mask without paying N95 prices.
