The best mask on the market!
This is my 2nd purchase.  I bought my first one 1 year before Covid for my allergies.  I stopped taking my allergie medication and wore this during high pollen days and it worked great!  I am a Public City Bus Operator and use this mask every day for Covid.  Their filters are the best.  I only wish that MeoAir would offer more like they used to especially filters.
