Why it matters

The Honeywell HHT-270W Air Purifier is a compact / desktop air purifier that its maker rates for 100 square feet.

At the usual 4.8 air changes an hour and an 8-foot ceiling, a 100-square-foot rating implies about 64 cubic feet of clean air a minute. In a 12-by-15-foot bedroom that would turn the air over roughly 3 times an hour.

Filtration: HEPA-Type.

Price-wise it sat in the cheapest 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 Allergies, Best Air Purifiers for Apartments and Dorms, Best Honeywell filters and air products, where it is ranked against every model that meets the same rule.

Its rated room size of 100 square feet is one of the smallest ratings we cover: 2 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 Honeywell HPA300 HEPA Air Purifier: rated room size 100 square feet here vs 2250 square feet.

Questions buyers ask

How big a room does the Honeywell HHT-270W Air Purifier cover?
The maker rates it for 100 square feet. Treat that as the room size for allergy-level cleaning; larger figures quoted per hour describe one air change, not continuous cleaning.
