Pros

  • The following models shouldn't use ionizers, although double checking [CARB] to verify that the model doesn't use electronic filtration wouldn't hurt. * ... * Coway Airmega 100
  • One purifier I’ve found that looked interesting was the coway airmega 100.
  • I have a Coway Airmega 100 and it’s pretty dang quiet in sleep mode.

Cons

  • I just wish the Airmega 100 was like... 2 inches (5 cm) shorter in all dimensions. It seems just bulky enough to be kinda a pain to move around.

  • Seeing a few with a CADR around 250m^3. Phillips Mini 900, Coway Airmega 100 both around £95.

Airmega 100: It states that it is a True HEPA filter on the website and their support also claims it is and is tested by Internet but is not willing to disclose any documentation or proof as such. Energy star lists this model as HEPA-Type and my understanding of the circular purifiers is they tend not to be real HEPA

The Coway models you listed would be underpowered for the ~500 sq. ft. space; you'd need ~334 CFM CADRs. ... I would avoid the Coway Airmega 100 in particular.

NB: I would *avoid* the Coway Airmega 100 (the cylindrical unit).
