Updated October 2026 · 5 dehumidifiers, no paid placements

Best Energy Efficient Dehumidifiers in 2026

A basement unit can run from May to October, so the power bill is part of the price. All five dehumidifiers here state ENERGY STAR certification in their own listing. Ranked on buyer ratings, review volume and specs, with the catch of each one spelled out.

Want the efficient pick without a spreadsheet? Start with the Yaufey 120-Pint, 6,000 sq ft. The other four carry the same label and differ on size and drainage. Only one variant per listing family is ranked, so these are five distinct ENERGY STAR units.

How to choose

Check the exact model on the ENERGY STAR list. Certification belongs to a model number, not to a brand or a product family. Look it up in the ENERGY STAR product finder before you count on the label or a rebate.
Size it right first. An undersized unit runs all day and an oversized one cycles constantly. The right size for your measured humidity saves more power than any label.
Let the humidistat do the saving. Set it around 45 to 50 % and give the water a continuous drain. The compressor switches off once the room gets there, which is where the real savings come from.

What the ENERGY STAR label tells you, and what it doesn't

ENERGY STAR certifies a dehumidifier on its Integrated Energy Factor: liters of water removed per kilowatt-hour, under the DOE rating procedure. The label tells you a model clears the bar for its size. It doesn't tell you by how much, and most listings never print the figure. Of the 61 eligible listings, one states a liters-per-kWh number and 17 claim the "Most Efficient" mark.

So we rank the certified units on ratings and specs, and show any stated efficiency figure next to the unit. Before you count on a utility rebate, look up the exact model number in the ENERGY STAR product finder; a brand being certified says nothing about the variant in your cart. The ENERGY STAR guide explains how to compare the figures, and a unit sized right for the room (see the sizing guide) saves more than any label.

How we rank

Every model gets a rating out of 10 from its exact listing: what buyers give it, how many of them there are, and how completely the seller documents the specs. The highest unrounded result wins; on an exact tie, the listing identifier decides.

When a #1 pick carries a rating we set ourselves, its formula result always sits right next to it. We haven't run these units in a basement of our own, and a commission never moves a rating or a rank.

Read the methodology →Affiliate disclosure

45 % buyer rating, damped when a listing has fewer than 50 reviews.
35 % review volume, on a logarithmic scale up to 5,000 reviews.
20 % documentation: feature bullets, images and stated brand of the listing.
Pints per day, coverage and drainage are shown only when the exact listing states them; seller test conditions vary, and we measure nothing ourselves.
One slot per listing family: variants of one parent listing, which usually share one review pool, count once and are listed under the best-rated variant.

Frequently asked questions

Which is the best energy efficient dehumidifier in 2026?

Our pick is the Yaufey 120-Pint, 6,000 sq ft, at 9.6/10 (excellent), straight from the formula. It has 6,463 buyer reviews averaging 4.5/5, a review pool shared by the Yaufey listing family (4 variants); its listing states 120 pints/day and up to 6,000 sq ft. Close behind: the AEOCKY Commercial, 8,000 sq ft at 9.6/10.

How is this ranking built?

We start from 61 dehumidifiers whose own listing states ENERGY STAR certification, each with a buyer review record. Each one gets a rating out of 10: 45 % buyer rating, 35 % review volume and 20 % how completely the listing documents its specs. Variants of one listing family (same parent listing or the same shared review pool) share a single slot: the best-rated variant represents the family, and the others are listed under it.

Are ENERGY STAR dehumidifiers worth it?

For a basement unit that runs for months, usually yes: the certified models remove more water per kWh than the minimum for their size, and some utilities pay a rebate on them. Check that the exact model number is on the ENERGY STAR list, not just the brand.

Which dehumidifier states the best efficiency?

Among the 61 eligible listings, the Avylo 90-Pint with Pump, White (2.05 L/kWh) is the only one that prints a liters-per-kWh figure. It is a seller figure, and a figure without its rating conditions is hard to compare.

How much does it cost to run a dehumidifier?

Multiply the unit's power draw (from the manual or the nameplate) by the hours it actually runs and your electricity rate. The humidistat matters as much as the label: a unit set to 50 % switches its compressor off once the room gets there.

Is a bigger dehumidifier less efficient?

Not per pint. A unit sized for the space reaches the set point and cycles off; an undersized one runs flat out all day. Our selection tool gives a starting size.

Are the prices up to date?

Each price is the one we recorded on Sep 30, 2026, and it may have changed since. The button always opens the exact listing with today's price and seller.

Have you used these dehumidifiers yourselves?

No, we haven't run these units in a basement of our own. The ratings come from what buyers say and from the specs stated in each exact listing, weighed with a formula we publish.
