Overview
Daikin stacks pre-filters, a HEPA filter and an activated carbon filter in this compact purifier, then adds a UVC LED aimed at what the HEPA traps. Dust and odor sensors set the fan, and side handles make it easy to move between rooms.
Odor and germ control on top of particle filtering is the case, with a quiet mode suited to sleep. Its rated coverage at frequent air changes is modest, so large rooms need more capacity.
Who it's for
People with allergies, pets or cooking odors in a single room. Large living areas need a higher capacity purifier.
Pros and cons
- Multi stage filtration
- UVC LED for trapped germs
- Odor reduction carbon filter
- Very quiet mode
- Modest room coverage
- Replacement filters needed
- Touch controls only
Performance notes
Air passes through pre-filters, HEPA and carbon in turn, with three directional intake pulling air from around the unit. Sensors adjust the fan for dust and odor, and the UVC LED works on contaminants held in the HEPA media.
