WOOZOO air purifiers against the median CADR/W of their DOE class. DOE data as of 2026-11-03.
DOE class	WOOZOO models	Above median	Class median	Best WOOZOO
Air purifiers, PM2.5 CADR 150+ cfm (140)	4	4	CADR/W 5.5	APF-45 CADR/W 7.2
Air purifiers, PM2.5 CADR 10 to 99 cfm (90)	2	0	CADR/W 3.5	APF-10 CADR/W 2.3

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

Who makes WOOZOO 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.

None of the 6 WOOZOO basic models is filed by another brand as of 2026-11-03, and none uses another company's model number. DOE's records tie them to WOOZOO alone.

How much does a WOOZOO air purifier cost to run?

DOE's annual energy figures for the 6 WOOZOO air purifiers that file one run from 116 to 279 kWh a year: about $21.07 to $50.67 a year. The lowest is WOOZOO APF-10 (41 cfm, CADR/W 2.3) and the highest WOOZOO APF-45 (342 cfm, CADR/W 7.2).

At 18.16¢ per kWh, the US average residential price for August 2026 (EIA Electric Power Monthly, table 5.6.A). Worked out from the certified figures.
