Dyson Air Purifier Black Friday 2026: Cool, Hot+Cool, Humidify

Dyson makes purifier fans in three hoop-top styles: Cool, Hot+Cool (with a heater) and Humidify+Cool, plus the larger Big+Quiet line. A listing should name the model code, since the code tells you whether it has a formaldehyde filter. Most models offer app and voice control, but check the listing for the model you want.

Reading the model codes

The BP04 also adds extra media for nitrogen dioxide.

Hoop-top machines move about 100 CFM of purified air, and the Big+Quiet models about 200 CFM, per one tester’s measurements.

Filters are part of the cost

Each machine uses a HEPA filter for particles and a carbon filter for gases. Both filter types need replacing in time; check which filter the model takes. One review notes that Big+Quiet HEPA filters run on a five-year cycle and carbon filters on two. The formaldehyde catalytic filter is described as permanent.

Choose the type by room

Pick Cool for year-round use, Hot+Cool if a heater in the room helps in winter, and Humidify+Cool for dry air. Big+Quiet suits a large room. A purifier does not replace ventilation: for a formaldehyde source, remove the source first.
