Why it matters
The Dyson Hushjet Compact Air Purifier is a compact / desktop air purifier that its maker rates for 203 square feet.
At the usual 4.8 air changes an hour and an 8-foot ceiling, a 203-square-foot rating implies about 130 cubic feet of clean air a minute. In a 12-by-15-foot bedroom that would turn the air over roughly 5 times an hour.
Filtration: Electrostatic. Quietest setting, per the listing: 42 db.
Price-wise it sat in the dearest third of the 30 compact / desktop models we cover when we checked; the button shows today's price.
It qualifies for our lists Best Air Purifiers for Apartments and Dorms, Best Air Purifiers for Home Offices, where it is ranked against every model that meets the same rule.
Its rated room size of 203 square feet is one of the smallest ratings we cover: 7 of the 152 purifiers with a stated figure come in lower, and the range runs from 62 square feet to 4,800 square feet.
Compared with the Dyson Purifier Hot+Cool HP07 Air Purifier: rated room size 203 square feet here vs 73 square feet.
