Review on Munchkin Portable Air Purifier: Advanced 4-Stage True HEPA Filtration System, Eliminates 99.7% of Micro-Pollutants on the Go! by Heather Stokes

I was looking for a small, portable, true HEPA air filtration system for extra protection in jazz clubs. It's about the size of a large soda can, very light, and almost entirely silent on low settings. I've put it down in front of me at a number of jazz gigs in the short time I've had it, and it gave me a bit of confidence without getting in the way of the music. It's small and certainly won't clean the whole room, but if it can unobtrusively clean the air around me it will increase the safety of wearing my mask. Very very very quiet on the lowest setting - you really can't hear it! Higher settings are louder and not for music venues, but when I travel by plane again this will be on my tablet.
