These air filters do not meet the filtration requirement to be considered a ‘HEPA air filter’. Because they fly in zigzag patterns, they end up hitting the fibers and getting stuck. For the really small particles (less than 0.3 microns), the science gets weirder. All particles? They thought that in a global pandemic scenario, we might run out of N95 masks. Only corporations benefit when clean air is a luxury. They’re made from either plastic (PP+PET) or fiberglass, and can capture things like pollen, viruses, bacteria, mold and PM2.5.
