How to choose
Calculate room volume and aim for sufficient particle clean-air delivery rate. For approximately five air changes per hour, CADR (m³/h) ≈ room area (m²) × ceiling height (m) × 5. Consider noise at the speed you will actually use, and confirm genuine replacement filters are available.
For smoke and odors, activated carbon can help, but small carbon layers are limited for gases. Avoid ozone-producing devices.
