Best praise vs top criticism for Coway Airmega 150
Best Praise
+12 pts“The [Coway Airmega 150](https://cowaymega.com/products/airmega-150) has a separate permanent pre-filter. This makes cleaning the pre-filter much easier and doesn't risk damaging the pleated HEPA media underneath. Airmega 150 also has higher CADRs. FYI: on Coway's website, the discount codes **COWAYMEGA10** or **FORYOU10** give an additional 10% off for the Airmega 150, which brings the price down to $122.40.”

+3 pts“So the bad news here is that the AirMega 150 moves around half the air of the other two. It has no onboard ionizer (which many consider a good thing), and it has green-HEPA medical grade filter with antimicrobial properties, so that's a plus, but it DOES move less air. It's quieter and looks nicer, but the CADR doesn't lie. In this case I'd advise to get the Levoit. I'm NOT a Levoit fan - in fact, I think they're generally a garbage company. But in this case it's CHEAPER, moves more air, has quite a good HEPA filter, and a carbon grid (which neither of the Coway models here do). HOWEVER, turn off the stupid smart features and cover the light when you get it. The air quality meter is a lie, the smart features just make it work worse. Turn it on, leave it on, and it'll be fine.”
