How efficient are COOLTURE air purifiers?

Of the 4 COOLTURE air purifiers, 1 files a higher CADR/W than the class median and 3 fall below it.

COOLTURE air purifiers against the median CADR/W of their DOE class. DOE data as of 2026-11-03.
DOE class	COOLTURE models	Above median	Class median	Best COOLTURE
Air purifiers, PM2.5 CADR 100 to 149 cfm (66)	2	0	CADR/W 4.65	K250F-C CADR/W 3.9
Air purifiers, PM2.5 CADR 10 to 99 cfm (90)	1	1	CADR/W 3.5	HAP-609 CADR/W 4.5
Air purifiers, PM2.5 CADR 150+ cfm (140)	1	0	CADR/W 5.5	KJ450F-A1 CADR/W 4.5

A higher CADR/W means more clean air per watt.

Who makes COOLTURE air purifiers?

DOE's database has no manufacturer field, so the evidence is whose model number each unit is filed under and which other brands file the same unit.

One unit is filed under COOLTURE's own model number and sold by other brands too, so COOLTURE is the filer of record for it.

COOLTURE shares 4 units with 14 other brands. Brands it shares with, and how many units each:

Questions about COOLTURE

Is COOLTURE a good air purifier brand?: How its 4 air purifiers compare on efficiency with their DOE class is above. 4 of them are the same unit as another brand's model. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
What room size are COOLTURE air purifiers rated for?: DOE's effective room size for its 4 rated models is 112 to 339 sq ft, from a certified smoke CADR 72 to 219 cfm. CADR and room size.
Which COOLTURE air purifier is the most efficient for its size?: COOLTURE HAP-609, at CADR/W 4.5: higher than 52 of the 90 in its DOE class (air purifiers, PM2.5 CADR 10 to 99 cfm). At the other end is COOLTURE KJ450F-A1, at CADR/W 4.5, higher than 38 of the 140 in its class.
Is COOLTURE the same as Aeitto?: For 2 units, yes: both file them under the same DOE basic model (KJ200F-C1 and KJ450F-A1). The other 2 COOLTURE basic models aren't filed by Aeitto. Compare the 6 brands of KJ200F-C1. Compare the 6 brands of KJ450F-A1.
