Review on Medify MA-50 Air Purifier - H13 True HEPA Filter, UV, 1100 sq ft Coverage - Smoke, Dust, Odor, Pet Dander Remover - Quiet 99.9% Removal to 0.1 Microns - White, 1-Pack by Tami Francis

I bought a Mediify MA-50 a few weeks ago as the Kaldor fire engulfed my area. I've had several smaller air purifiers, but they just didn't work. The day I received the MA-50, the air quality in my area was very bad. I have a Purple Air air quality sensor at home that reads AQI 150 with LARPA conversion, while an external Purple Air air quality sensor reads AQI 482. Within an hour, the MA-50 determined the air quality. in the area of my house, in a room of 800 square meters. Foot where it was with an AQI of less than 10. This air purifier is pretty quiet up to level 3. At level 4, I measured 60dB from four feet, which is acceptable. for me at times when I have to push it so high. At the same distance, level 3 was 45dB.
