Review on 🌬️ Filtrete Allergen Delivers Full Particle Protection: Effective Air Filtration Solution by Jared Winebrenner

They match our air conditioner but in the course of research I found out that the MPR 1900 filters 0.3 microns, the same characteristics as the N95! Also from 3M. Coincidence? Lowe wears this filter. I bought a 16x30 and 16" became 80". If you make a standard 9" x 9" cut, you can make masks quickly. 10 minutes for that. Be sure to install a 5 inch soft nose bridge. They can be made with a sewing machine and/or a glue gun, or both. We made a bunch and gave them away. Our church makes them.
