How efficient are Cuckoo air purifiers?

Of the 7 Cuckoo air purifiers, 4 file a higher CADR/W than the class median, 1 matches it and 2 fall below it.

Cuckoo air purifiers against the median CADR/W of their DOE class. DOE data as of 2026-11-03.
DOE class	Cuckoo models	Above median	Class median	Best Cuckoo
Air purifiers, PM2.5 CADR 150+ cfm (140)	6	4	CADR/W 5.5	CAC-F3010FW CADR/W 7.8
Air purifiers, PM2.5 CADR 10 to 99 cfm (90)	1	0	CADR/W 3.5	CAC-I0510FW CADR/W 3

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

Who makes Cuckoo 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 7 Cuckoo 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 Cuckoo alone.

How much does a Cuckoo air purifier cost to run?

DOE's annual energy figures for the 7 Cuckoo air purifiers that file one run from 116 to 406 kWh a year: about $21.07 to $73.73 a year. The lowest is Cuckoo CAC-I0510FW (59 cfm, CADR/W 3) and the highest Cuckoo CAC-F3010FW (552 cfm, CADR/W 7.8).

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.
