Our Verdict

Dyson Purifier Hot+Cool HP07

Dyson Purifier Hot+Cool Formaldehyde HP09

The Dyson Purifier Hot+Cool Formaldehyde HP09 is a little more feature-rich than the Dyson Purifier Hot+Cool HP07, though both appliances will deliver similar overall performance in most scenarios. Only the HP09 has an added catalytic filter for trapping formaldehyde, a colorless gas that a huge variety of indoor sources can release, ranging from paint to particleboard. That said, we don't currently test for formaldehyde absorption, and are unable to validate this claim.
