Dyson HushJet Big+Quiet Cool Pure+

Whole-Room Airflow Without the Roar

The Dyson HushJet Big+Quiet Cool Pure+ is built to move purified air across unusually large spaces while keeping noise low. Its horizontal HushJet airflow can project as far as 20 meters and process up to 334 liters of air per second. Dyson says that reach can clean large or connected rooms in half the time of its earlier approach.

A Silencer Shapes the Air

HushJet technology controls turbulence inside the machine instead of simply slowing the fan. The purifier drops to a claimed 14.5 decibels in night mode while continuing to circulate air. That combination matters in bedrooms and offices, where a powerful purifier is only useful if people can tolerate leaving it on.

Filtration Goes Beyond Visible Dust

The multilayer system captures 99.999 percent of particles as small as 0.01 microns under Dyson's test conditions. It also removes gases, breaks down formaldehyde, and targets allergens, volatile organic compounds, and odors. The machine doubles as a cooling fan, though it is separate from Dyson's later three-in-one model with heating.

Dyson's Biggest Purifier Arrives This Year

At $1,099, the Big+Quiet Cool Pure+ is priced for homes that need more coverage than a compact room unit can provide. Its identity rests on combining high-volume airflow with a night setting quiet enough for occupied spaces. Dyson plans to release it in late 2026.
