How efficient are YADU air purifiers?

Of the 8 YADU air purifiers, none files a higher CADR/W than the class median: 8 fall below it.

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

Who makes YADU 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.

YADU shares 8 units with 4 other brands. Brands it shares with, and how many units each:

• EZDONE8
• BAREN1
• KOIOS1
• MOOKA1

How much does a YADU air purifier cost to run?

DOE's annual energy figures for the 8 YADU air purifiers that file one run from 81 to 208 kWh a year: about $14.71 to $37.77 a year. The lowest is YADU APH080-24D (44 cfm, CADR/W 3.3) and the highest YADU EAH-D2-1 (123 cfm, CADR/W 3.6).

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.

Questions about YADU

Is YADU a good air purifier brand?

How its 8 air purifiers compare on efficiency with their DOE class is above. 8 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 YADU air purifiers rated for?

DOE's effective room size for its 8 rated models is 68 to 191 sq ft, from a certified smoke CADR 44 to 123 cfm. CADR and room size.

Which YADU air purifier is the most efficient for its size?

YADU APH080-24D, YADU EAH-B1, YADU EAH-B1-1 and 4 more tie at CADR/W 3.3: higher than 34 of the 90 in its DOE class (air purifiers, PM2.5 CADR 10 to 99 cfm). At the other end is YADU EAH-D2-1, at CADR/W 3.6, higher than 16 of the 66 in its class.

Is YADU the same as EZDONE?

For 8 units, yes: both file them under the same DOE basic model (APH080-24D, EAH-B1, EAH-B1-1, EAH-B1-2 and 4 more).
