I would stay away from Winix even how cheap they are. I have C545 model and after a few years, the motor started to make a whirring noise even at the lowest speed. It is a common issue with Winix models. I bought 3 Coway Airmega 200M and they are much quiet.

Waoowww.Project Farm pushes these motors and filters through absolute worst-case scenarios, choking them with extreme smoke and particulate matter, to simulate years of normal wear and tear in a fraction of the time. He measures exact CFM drops, power draw and efficiency degradation under heavy load. That kind of controlled, extreme testing proves a motor's long-term durability far better than someone just running it on low in their bedroom and waiting a few years. You DON'T NEED five years to test long-term performance when you actually know how to stress-test a machine😉 I have exact same air purifier in my home and I am so satisfied. Do you???
