Overview
Cleaning a bedroom or home office is what this Coway Airmega purifier does, pulling air through a pre-filter, a deodorization filter and a HEPA filter. Auto mode watches air quality and sets the fan, and sleep mode darkens the lights.
Auto and sleep modes make it easy to leave running in a bedroom. Physical size, noise and power use are missing.
Who it's for
Allergy sufferers and pet owners cleaning a single room get HEPA filtration with odor reduction. Buyers who want published noise figures or large-space coverage should compare elsewhere.
Pros and cons

Performance notes
Coverage depends on air changes per hour, which the room figures describe. The deodorization stage reduces odors and VOCs that HEPA alone cannot. Auto mode raises speed when the sensor reads poor air and slows when it clears.
