Review on Enhanced Protective Replaceable Activated Carbon Filter by James Broome

I bought these PM 2.5 Activated Carbon Filters Meltblown Nonwoven Liner 5 Ply Filters Replacement filter paper (20 pack) to put in my face masks when I return to class next week at school. I like the idea of having an extra layer and they work well. They slide right into the mask and stay in place. Then they are disposable. I love adding them. They make me feel much safer and that I can protect others better. I will order more when they run out.
