Octo's answer
π Top pick: Blueair Blue Signature Large4.0/5
The Blueair Blue Signature Large scores well for coverage, filtration, and relatively quiet operation. The Coway Airmega Mighty2 is a more compact option, while the Coway Airmega ProX may suit larger rooms depending on local pricing and noise tolerance. Compare independently tested CADR, filter costs, room size, and controls rather than relying on a single overall winner.
