Overview
Not a basic filter-only purifier, the DustMagnet adds a function that pulls airborne dust out of the air before it settles on floors and surfaces. Two combo filters, one at the top and one at the bottom, combine a particle filter with carbon.
Smart features such as a clean air countdown and a leaving-home mode work through the app, and the Scandinavian look suits a living room. Coverage is quoted in two units, and the app is needed to unlock the smart functions.
Who it's for
Homes with dust, pet dander and cooking odors that want voice and app control suit it. Anyone who does not want to use an app or smart assistant would not get its full feature set.
Pros and cons
- DustMagnet dust capture
- App and voice control
- Tabletop friendly design
- Smart features need the app
- Coverage listed in two units
- Spare filters not mentioned
Performance notes
Air passes through the two combo filters, and electrostatic charging of particles helps capture them at lower fan speeds. The dust function targets airborne dust before it settles. The stated CADR values apply at the top fan setting, so quieter settings clean more slowly.
