Review on 🔍 Polypropylene Disposable Face Mask Filter Insert (20 Pack) - 95% Efficient, 3 3/8" X 6" Size by Mario Haan

This was my second order of these filters (I've ordered 4 packs each time). I originally bought these to give to my friend who works in law enforcement. I wasn't sure if the other online mask filters from China were really what they claimed. These are 4" x 6" and fit perfectly in the bag of reusable masks (which I bought from a local gym supply store that thinks outside the box!). I'm quarantined at home and feeling helpless so I'm buying local. made masks and these filters to distribute to local emergency responders, nursing homes and healthcare workers. They wash their masks daily and change these filters as needed. This company is fantastic - they deliver very quickly and I look forward to continuing to do business with them. If I win the lottery I will buy masks and filters for ALL our essential workers until we have a vaccine :-)
