LG LP0621WSR

4.0

2 sourcesall derived

The LG LP0621WSR is the small-room value pick: a compact 8,000 BTU ASHRAE (6,000 BTU DOE) unit that cools spaces up to 250 sq ft quickly and quietly for less than the bigger units here. Reviewers praise its ease of use and fast small-room cooling, noting it runs as low as 51 dB. It is not for large rooms and there are no smart features, but for a bedroom or office on a budget it is an efficient fit.

Strengths

— Affordable, compact unit ideal for small rooms up to 250 sq ft
— Cools a small room quickly — one office in about 15 minutes
— Quiet at low fan, as low as 51 dB

Watch-outs

— Low 6,000 BTU DOE capacity limits it to small spaces
— Single-hose design is less efficient than dual-hose units
— No Wi-Fi or inverter; basic feature set

Ranked #4 in Best Portable Air Conditioners

LG LP1419IVSM

3.9

2 sources

The LG LP1419IVSM is a powerful, quiet single-hose portable AC built around LG's dual-inverter compressor. LG rates it as low as 44 dB, which is bedroom-quiet for a single-hose unit. A high real SACC rating and Wi-Fi control make it the top single-hose pick, trailing only the dual-hose Midea Duo on pure efficiency.

Strengths

— Dual-inverter compressor runs as quiet as 44 dB, great for bedrooms
— Fast, powerful cooling — drops a 150 sq ft room 15 degrees in 30 minutes
— High real SACC capacity that beats most single-hose competitors

Watch-outs

— Single-hose design is inherently less efficient than dual-hose
— Large and heavy at roughly 70 lbs and 2.5 feet tall
— Premium price

How they stack up

LG LP0621WSR

The smallest and most affordable unit here, sized for rooms the larger Midea Duo MAP12S1TBL, LG LP1419IVSM, and Whynter ARC-14S would over-cool. Like the LG LP1419IVSM and Black+Decker BPACT12HWT it is a single-hose design, so it is less efficient than the dual-hose Midea Duo, but its low capacity is well-matched to small spaces.

LG LP1419IVSM

The best single-hose unit here, using an inverter compressor like the Midea Duo MAP12S1TBL for quiet operation — but as a single-hose design it is less efficient than the dual-hose Duo. It cools faster and quieter than the dual-hose Whynter ARC-14S and the Black+Decker BPACT12HWT, and it is far more powerful than the small-room LG LP0621WSR.
