Will it cover my room?

Check your room before you buy

Most cheap purifiers are rated for one bedroom. This one is rated for a large open-plan space at two air changes an hour, or half that area at four changes an hour for allergy sufferers.

Inside

Six stages, in one quiet machine

  1. Pre-filter · hair, dust and lint
  2. Medium filter · larger particles
  3. HEPA · the smallest particles
  4. Your custom filter · germs, pets, odor or toxins
  5. Activated carbon · odors and VOCs
  6. Ion generator · optional, zero ozone (UL 2998)
Whisper quiet

Quiet enough to sleep next to

Set it to auto and its particle sensors read the room: it speeds up when the air gets worse and drops back down when it's clean.
