COWSAR: 68 DOE certified models

COWSAR has 68 basic models certified to DOE as of 2026-11-03: 50 portable ACs (5,000 to 10,200 BTU/h SACC), 3 window ACs (6,200 to 8,100 BTU/h), 12 dehumidifiers (5 to 49.86 pints/day under the 2019 DOE test) and 3 air purifiers (smoke CADR 78 to 297 cfm). 60 are the same unit as models filed under other brands. How their efficiency compares with their DOE class is below.

Highest certified cooling capacity among its portable ACs: COWSAR A5410CE, COWSAR NPH-10C/X1E and COWSAR NPH-10CE tie at 10,200 BTU/h SACC.
Most efficient for its class: COWSAR OL-A018DD10N3BP/S, CEER 12, higher than 1,035 of the 1,044 single hose portable ACs certified to DOE.
Highest certified cooling capacity among its window ACs: COWSAR 54091EWA0-8K-CS and COWSAR 54091EWA1-8K-CS tie at 8,100 BTU/h.
Most efficient for its class: COWSAR 54091EWA0-8K-CS, CEER 16.3, higher than 102 of the 105 in its DOE class (window ACs, 8,000 to 13,999 BTU/h).
Highest certified water removal among its dehumidifiers: COWSAR D026W-50Pt3M at 49.86 pints/day.
Highest certified smoke CADR among its air purifiers: COWSAR AP4416-UL at 297 cfm.
Most efficient for its class: COWSAR AP1020-WHITE, CADR/W 5.8, higher than 80 of the 90 in its DOE class (air purifiers, PM2.5 CADR 10 to 99 cfm).

Air purifiers

Of the 3 COWSAR air purifiers, 2 file a higher CADR/W than the class median and 1 falls below it.

COWSAR air purifiers against the median CADR/W of their DOE class. DOE data as of 2026-11-03.

A higher CEER means more cooling per watt. A higher IEF means more water removed per kWh. A higher CADR/W means more clean air per watt.

Who makes COWSAR portable ACs, window ACs, dehumidifiers and 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.

2 of the 68 COWSAR basic models are filed under another company's number: 1 under Byzeng's own model number and 1 under Keeping's own model number.

COWSAR shares 60 units with 48 other brands. Its other 8 basic models are filed by COWSAR alone. Brands it shares with, and how many units each:

How much do COWSAR models cost to run?

While cooling, COWSAR portable ACs draw about 696 to 1,291 W (certified SACC divided by CEER). That's 13¢ to 23¢ an hour, or $30.34 to $56.27 for 30 days at 8 hours a day. The lowest is COWSAR AC7290-10K (5,500 BTU/h SACC, CEER 7.9) and the highest COWSAR A5410CE (10,200 BTU/h SACC, CEER 7.9).

While cooling, COWSAR window ACs draw about 460 to 610 W (DOE's listed power input). That's 8¢ to 11¢ an hour, or $20.05 to $26.59 for 30 days at 8 hours a day. The lowest is COWSAR 54091EWA0-6K-CS (6,200 BTU/h, CEER 15.1) and the highest COWSAR 54091EWA0-8K-CS (8,100 BTU/h, CEER 16.3).

Running nonstop at DOE's test conditions, the 12 COWSAR dehumidifiers with both figures use 1.82 to 11.71 kWh a day. That's about 33¢ to $2.13 a day, or $9.91 to $63.79 for 30 days. The lowest is COWSAR 75032EDE0-WHITE-CS (5 pints/day, IEF 1.3) and the highest COWSAR 75026EDE0-WHITE-CS (49.74 pints/day, IEF 2.01).

DOE's annual energy figures for the 3 COWSAR air purifiers that file one run from 82 to 259 kWh a year: about $14.89 to $47.03 a year. The lowest is COWSAR AP1020-WHITE (78 cfm, CADR/W 5.8) and the highest COWSAR 74025EAP0-WHITE-CS (147 cfm, CADR/W 3.6).

Real use cycles on and off with the humidity, so the dehumidifier figures are the upper end for a day of nonstop running.

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 COWSAR

Is COWSAR a good dehumidifier brand?: How its 12 dehumidifiers compare on efficiency with their DOE class is above. 12 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.
Does COWSAR make a 50 pint dehumidifier?: Yes, by the 2019 DOE test: 2 of its models certify 49.5 pints/day or more, led by COWSAR D026W-50Pt3M at 49.86 pints/day. By DOE class: 8 in the up to 25 pints/day class and 4 in the 25 to 50 pints/day class. How the 2019 test changed pint ratings.
Which COWSAR dehumidifier is the most efficient for its size?: COWSAR OL25-D022CCN3B1/E, at IEF 2.04: higher than 251 of the 253 in its DOE class (portable dehumidifiers up to 25 pints/day). At the other end is COWSAR 75032EDE0-WHITE-CS, at IEF 1.3, tied with 62 others at DOE's 1.30 minimum.
Is COWSAR the same as ZAFRO?: For 59 units, yes: both file them under the same DOE basic model (A010L-8K, A011D2-10K, A011E-8K, A4208K-WHITE and 55 more). The other 9 COWSAR basic models aren't filed by ZAFRO.
