Overview
Coway packs three filters into one cartridge in the Airmega purifier: a washable pre-filter, a carbon layer for odors and a HEPA layer for fine particles. An air quality sensor drives auto mode, raising and lowering the fan as the air changes.
Auto mode and a single cartridge make it low effort to live with, and the carbon layer handles cooking and pet odors. Noise levels and replacement intervals are missing from the listing, which matter in a bedroom.
Who it's for
Allergy sufferers, pet owners and light sleepers in mid size rooms will get hands off cleaning. Large open plan spaces may need a bigger unit.
Pros and cons
- Three filter stages in one cartridge
- Auto mode adjusts the fan
- Carbon layer reduces odors
- Clean, easy filter swap
- Noise level not listed
Performance notes
Air passes the washable pre-filter, then carbon for odors and gases, then HEPA for fine particles. Auto mode reads air quality and raises fan speed when it worsens, so the room is cleaned faster when it matters.
