LG ventless heat pump dryer review: for homes with no vent to use

This dryer exists for one kind of home: a rental, condo or closet with no way to run a duct outside. I haven't used it. Consumer Reports has it in its dryer ratings, with cycle time as a category, but those scores sit behind a membership. I couldn't open any other timed lab test of this model, so the numbers below are LG's ratings, Abt's listing and general guidance from ENERGY STAR and This Old House.

The problem it solves

A conventional dryer pushes hot, wet air through a vent. ENERGY STAR explains that a heat pump dryer runs a closed loop and condenses the moisture out, so no vent is needed. It also says that avoiding a new vent can be a significant saving at installation.

If your laundry closet already has a working vent, this argument disappears. Buy something else.

Measure these first

The two sources I read disagree on depth, so don't plan from one:

LG's sheet is a Canadian version dated November 9, 2023. It prints the size as 23 5/8 by 27 1/4 by 33 1/2 inches under a label reading width, height, depth, and I've read 33 1/2 as the height because that's what Abt lists. I'd plan for the deeper number, then add room for the hose and cord. The door is reversible, per both, which helps in a tight closet.

Two utility checks catch people out:

• Power. Abt lists it as 240 V, 30 A, while LG's sheet says 120/240 V drawing 3.1 A. Abt also notes that the maker doesn't include a power cord, so match one to your outlet. This Old House says most heat pump dryers run on standard 120 V circuits, but neither page says that of this model. With only a 120 V outlet, I'd ask an electrician first.
• Water. ENERGY STAR says the condensed water has to drain, or go in a tank you empty after each load. Abt's box list has a drain hose. Neither page gives this model's tank size, so I'd plan on a drain within reach, and read the manual before you order if there isn't one.

Who it suits

Capacity is 4.2 cu ft. ENERGY STAR calls anything under 4.4 cubic feet compact. Homestar Appliances, a retailer, offers a rule of thumb that a dryer should be about double the washer's capacity. That means this one matches a washer of about 2 cubic feet, which is the compact class. The Bosch compact in our washer sizing guide, at 2.2 cu ft, is the kind of pairing I mean.

So: one or two people, a stacked pair in a closet, loads washed often. Abt's listing has a stacking kit in the box.

I wouldn't pair it with a family-size top-loader. Put a 4 cu ft washer's load in here and I'd expect to split it. Going by Homestar's rule, that washer wants a dryer of about 7 cubic feet.

What you trade

Time. This Old House says heat pump dryers typically take longer than conventional electric dryers because they run at lower temperatures. It gives no minutes, and neither does LG's sheet. It also suggests a high-spin front-loading washer to help. That favors the compact pairing again: Bosch rates its compact at 1,400 rpm.

Heat. Lower temperatures are gentler on delicates, per This Old House.

Control. LG's sheet lists "N/A" under temperature settings, three drying levels and two modes. Abt lists three temperature settings. Another disagreement. Check the manual if you dry a lot of delicates.

Energy, in your favor. ENERGY STAR says certified heat pump dryers use around 70% less energy than conventional dryers. This Old House says 40% to 50%. Those are general claims about the type, not measurements of this dryer. LG's sheet gives a combined energy factor of 6.4, which is its rating. ENERGY STAR adds that the biggest savings go to people with high dryer use and high electricity rates. Someone running two loads a week should expect far less back.

It has 14 drying cycles, plus Wi-Fi and sensor drying. Those are fine. They aren't the reason to buy it.

Price

$1,749 is the list price, checked November 2, 2026. Check it again before you budget.

What would make me skip it

• A working vent already exists.
• You need to dry king bedding at home, or you wash big loads with a full-size washer.
• No drain nearby and no outlet you can use.
• Drying time matters more than anything else. I'd want a measured number first, and I couldn't open one.
