Dyson air purifiers against the median CADR/W of their DOE class. DOE data as of 2026-11-03.
DOE class	Dyson models	Above median	Class median	Best Dyson
Air purifiers, PM2.5 CADR 10 to 99 cfm (90)	17	0	CADR/W 3.5	TP11 CADR/W 2.6
Air purifiers, PM2.5 CADR 150+ cfm (140)	7	4	CADR/W 5.5	JC01-A CADR/W 13.5
Air purifiers, PM2.5 CADR 100 to 149 cfm (66)	1	1	CADR/W 4.65	SP01-A CADR/W 7.4

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

Who makes Dyson 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 25 Dyson 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 Dyson alone.

How much does a Dyson air purifier cost to run?

DOE's annual energy figures for the 25 Dyson air purifiers that file one run from 114 to 559 kWh a year: about $20.70 to $101.51 a year. The lowest is Dyson SP01-A (139 cfm, CADR/W 7.4) and the highest Dyson BP10-A (591 cfm, CADR/W 6.2).

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.
