oneisall air purifiers against the median CADR/W of their DOE class. DOE data as of 2026-11-03.
DOE class	oneisall models	Above median	Class median	Best oneisall
Air purifiers, PM2.5 CADR 100 to 149 cfm (66)	2	1	CADR/W 4.65	PP02 CADR/W 4.9
Air purifiers, PM2.5 CADR 150+ cfm (140)	1	0	CADR/W 5.5	PP04 CADR/W 4.2

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

Questions about oneisall

Is oneisall a good air purifier brand?: How its 3 air purifiers compare on efficiency with their DOE class is above. One of them is 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 oneisall air purifiers rated for?: DOE's effective room size for its 3 rated models is 203 to 251 sq ft, from a certified smoke CADR 131 to 162 cfm. CADR and room size.
Which oneisall air purifier is the most efficient for its size?: oneisall PP02, at CADR/W 4.9: higher than 35 of the 66 in its DOE class (air purifiers, PM2.5 CADR 100 to 149 cfm). At the other end is oneisall PP04, at CADR/W 4.2, higher than 31 of the 140 in its class.
Is oneisall the same as tusson?: For one unit, yes: both file it under the same DOE basic model (PP02). The other 2 oneisall basic models aren't filed by tusson. Compare the 2 brands of PP02.
