A round, app-connected Winix tower with a verified CADR and air quality sensors. Cleans a large living room.
Verdict
Who it's for
A compact round tower that cleans a large living room, with AHAM's verification, air quality sensors and app control. Like other Winix models it has a PlasmaWave ionizer: the manual says it's on when the unit first starts, and a button turns it off.
Good
- CADR verified by AHAM
- Air quality sensors and auto mode
- App control
- HEPA and carbon filters last about a year
Trade-offs
- PlasmaWave ionizer is on by default
- Box headline is based on one air change an hour

The box vs the maths
The box says 2,006 sq ft186 m². It really cleans 411 sq ft38 m².
To clean 2,006 sq ft186 m² it would only change the air in the room 1 time an hour. We size every purifier at 4.8 air changes an hour, the level AHAM's room-size guideline works out to.
Winix's figure is the room it can change the air of once an hour, and the wording says as much. That's a real number, but at one air change an hour smoke and pollen come back in nearly as fast as the purifier removes them.
459 m³/h smoke CADR ÷ (4.8 × 2.5 m ceiling) = 38.2 m² = 411.5 sq ft38.2 m²
Use the calculator for your exact room and ceiling, or read how we pick.
Drawn to scale: the box says “Also cleans rooms up to 2,006 sq ft in 1 hour”, the purifier really cleans 411 sq ft, 4.9 times less.Drawn to scale: the box says “Also cleans rooms up to 2,006 sq ft in 1 hour”, the purifier really cleans 38 m², 4.9 times less.
Room sizes
Which rooms it fits
It suits 215 sq ft20 m², 269 sq ft25 m² and 322 sq ft30 m² rooms best: there it has 26–90% more air than the room needs, so it needn't run flat out. At 376 sq ft35 m² it only just keeps up (8% to spare), so it would run near its top speed, usually its loudest (why we don’t list noise). In rooms of 161 sq ft15 m² or less it's more than twice the size needed; a smaller model does the job.
Under a 2.7 m ceiling it covers 381 sq ft, under 3 m 342 sq ftUnder a 2.7 m ceiling it covers 35 m², under 3 m 31 m², so with a 3 m ceiling it no longer covers 376 sq ft35 m² (why).
For a 430 sq ft room or bigger it's too small, although the box claims 2,006 sq ft: the For a 40 m² room or bigger it's too small, although the box claims 186 m²: the 430 sq ft40 m² page lists models that cover it.
