Airpurifier Purchase Request Help
I took my data from the CR website which has the most current information. The Coway Airmega 300 has a poor rating of 53 where the top rated model in that category has a score is 85. Dust/pollen rating is 1 out of 5 at low speed, 4/5 at high speed but is noisy 3/5.
