LG: 60 DOE certified models

LG has 60 basic models certified to DOE as of 2026-11-03: 29 portable ACs (5,000 to 10,200 BTU/h SACC), 9 window ACs (6,000 to 23,500 BTU/h), 9 dehumidifiers (24.99 to 49.81 pints/day under the 2019 DOE test) and 13 air purifiers (smoke CADR 305 to 309 cfm). 6 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: LG LP1025WHSM at 10,200 BTU/h SACC.
Most efficient for its class: LG LP1022FVSM, LG LP1026WSSM, LG LP1027WS and 2 more, tied at CEER 7.9, higher than 738 of the 1,044 single hose portable ACs certified to DOE.
Highest certified cooling capacity among its window ACs: LG LW2422IVSM at 23,500 BTU/h.
Most efficient for its class: LG LW8001CSY, CEER 17.6, higher than 104 of the 105 in its DOE class (window ACs, 8,000 to 13,999 BTU/h).
Highest certified water removal among its dehumidifiers: LG DT501BKR0, LG DT501BWR0 and LG DT501BYR0 tie at 49.81 pints/day.
Highest certified smoke CADR among its air purifiers: LG AS601HHB0 at 309 cfm.
Most efficient for its class: LG AS601HBB0, CADR/W 6.6, higher than 107 of the 140 in its DOE class (air purifiers, PM2.5 CADR 150+ cfm).

Portable dehumidifiers up to 25 pints/day (253)	3	3	IEF 1.7	DT251BKR0 IEF 1.71

Air purifiers

Of the 2 LG air purifiers with a class big enough to compare, 2 file a higher CADR/W than the class median.

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

Air purifiers, PM2.5 CADR 150+ cfm (140)	2	2	CADR/W 5.5	AS601HBB0 CADR/W 6.6

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 LG 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.

One unit is filed under LG's own model number and sold by other brands too, so LG is the filer of record for it.

LG shares 6 units with 9 other brands. Its other 54 basic models are filed by LG alone. Brands it shares with, and how many units each:

How much do LG models cost to run?

While cooling, LG portable ACs draw about 758 to 1,291 W (certified SACC divided by CEER). That's 14¢ to 23¢ an hour, or $33.02 to $56.27 for 30 days at 8 hours a day. The lowest is LG LP0526PWF (5,000 BTU/h SACC, CEER 6.6) and the highest LG LP1025WHSM (10,200 BTU/h SACC, CEER 7.9).

While cooling, LG window ACs draw about 510 to 2,570 W (DOE's listed power input). That's 9¢ to 47¢ an hour, or $22.23 to $112.01 for 30 days at 8 hours a day. The lowest is LG LW6023IVSM (6,000 BTU/h, CEER 15.5) and the highest LG LW2422IVSM (23,500 BTU/h, CEER 14.5).

Running nonstop at DOE's test conditions, the 9 LG dehumidifiers with both figures use 6.92 to 11.73 kWh a day. That's about $1.26 to $2.13 a day, or $37.67 to $63.88 for 30 days. The lowest is LG DT251BKR0 (24.99 pints/day, IEF 1.71) and the highest LG DT501BKR0 (49.81 pints/day, IEF 2.01).

DOE's annual energy figures for the 2 LG air purifiers that file one run from 266 to 312 kWh a year: about $48.31 to $56.66 a year. The lowest is LG AS601HBB0 (305 cfm, CADR/W 6.6) and the highest LG AS601HHB0 (309 cfm, CADR/W 5.8).

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 LG

Is LG a good dehumidifier brand?: How its 9 dehumidifiers compare on efficiency with their DOE class is above. All 9 are filed under LG alone. We don't test reliability, noise or build quality, so we can't rank brands on those. How we compare models.
Does LG make a 50 pint dehumidifier?: Yes, by the 2019 DOE test: 3 of its models certify 49.5 pints/day or more, led by LG DT501BKR0 at 49.81 pints/day. By DOE class: 3 in the up to 25 pints/day class and 6 in the 25 to 50 pints/day class. How the 2019 test changed pint ratings.
Which LG dehumidifier is the most efficient for its size?: LG DT251BKR0, LG DT251BWR0 and LG DT251BYR0 tie at IEF 1.71: higher than 144 of the 253 in its DOE class (portable dehumidifiers up to 25 pints/day). At the other end are LG DT351BKR0, LG DT351BWR0, LG DT351BYR0 and 3 more, at IEF 2.01, higher than 161 of the 296 in its class.
Is LG the same as TCL?: For 5 units, yes: both file them under the same DOE basic model (TAC-05CPD/SL5, TAC-06CPD/SL5, TAC-07CPD/DL5(LC), TAC-08CHPD/DM1(LC) and 1 more). The other 55 LG basic models aren't filed by TCL.
