PM2.5 FILTERS for Masks (100-pk) - FINAL SALE


100 pcs of filters.

  • Child: approx 2-1/2" x 3-3/4" 
  • Adult: approx 3-1/4" x 4-1/2"

These disposable 5-layer PM 2.5 filters are supposed to help block dust, odor, and other pollutants.

FYI: Melt blown fabric is the most important element in filtering.  Some filters don't include 2 layers of the melt blown. So I cut one filter open to make sure there are actually 5 layers, including 2 layers of melt blown.
