Top 10 Dehumidifiers for Basements

Ranked on ENERGY STAR-certified capacity and efficiency — not the inflated pre-2019 pint numbers.

10 picks · Updated 2026-07-19 · Independently ranked

The best dehumidifiers for damp and wet basements, ranked on the numbers that are independently certified — ENERGY STAR's current-standard (2019 DOE test method) water-removal capacity and Integrated Energy Factor — plus real differentiators like built-in condensate pumps and ENERGY STAR Most Efficient status. Every pick and its numbers come straight from our sortable capacity data table; we've added a pick for each use case, from a small basement room to a whole-home ducted system for a very wet space.

1

Best for: best overall for basements

Midea 50-Pint with Pump (MAD50PE1QWT-B)

A full 50-pint-class unit (current DOE rating — roughly the old 70-pint class) with a built-in condensate pump, from the OEM platform that supplies several other brands on this list — a proven, widely serviced design at a mainstream price.

  • Full 50-pint-class ENERGY STAR-certified capacity for a whole basement
  • Built-in pump drains uphill to a sink or window — no floor drain required
  • Widely available parts and service; the same platform underpins several other brands
  • Not an ENERGY STAR Most Efficient model — mid-pack IEF for its class
  • ~$310 street is a premium over the no-pump version of the same unit

Best for: best for large or very wet basements

Santa Fe Ultra V125 Whole-Home

A ducted, whole-home dehumidifier rated to remove about 103 pints/day — several times a portable's capacity — and ENERGY STAR Most Efficient certified. The right call for a large, multi-room, or persistently wet basement where a portable unit would run flat out and never catch up.

  • ~103 pint/day capacity — handles a large or very wet basement a portable can't
  • ENERGY STAR Most Efficient certified; strong IEF for its class
  • Ducted install keeps the unit and its noise out of living space
  • ~$2,700 street plus professional installation — a different budget category
  • Overkill and poor value for a small or moderately damp space

3

Best for: best value

Keystone 50-Pint (KSTAD504G)

Full 50-pint-class certified capacity at the lowest street price we found for that class — the most basement-drying capacity per dollar on this list, if you have a floor drain or don't mind a bucket.

  • Full 50-pint-class capacity at a below-average price for the class
  • Common big-box availability and accessories
  • No pump variant in this line — gravity drain or manual bucket only
  • Not an ENERGY STAR Most Efficient model
$245.00 street est. — unverified
4

Best for: best with pump / smart features

Honeywell 50-Pint with Pump (TPFIT50APWK)

A pump-equipped 50-pint-class unit that's also Wi-Fi connected per its ENERGY STAR certification listing — check humidity and cycle status from a phone app instead of walking down to the basement.

  • Built-in pump plus Wi-Fi connectivity (per ENERGY STAR certification data)
  • Full 50-pint-class capacity for a whole basement
  • Premium price for the connected-plus-pump combination
  • App/Wi-Fi reliability for smart-home features varies by household network

Best for: best for a finished or lived-in basement

Aprilaire E080 Whole-Home

A ducted 65-pint-class system, ENERGY STAR Most Efficient certified, built to install away from living space — no portable-unit compressor hum in the room. (We don't have lab-measured decibel figures for the portables on this list, so this is a design-based pick, not a tested noise comparison.)

  • ENERGY STAR Most Efficient certified; strong IEF for a whole-home system
  • Ducted install means no compressor noise in the finished space
  • Requires professional installation and existing or new ductwork
  • ~$1,900 street before installation — a major investment vs. a portable

6

Best for: best ENERGY STAR Most Efficient portable

Whirlpool 25-Pint, Most Efficient (WHAD251AW)

One of the few portable units on this list that clears ENERGY STAR's stricter Most Efficient bar — the best efficiency-per-dollar pick for a single basement room that runs most of the day through summer.

  • ENERGY STAR Most Efficient certified in the 25-pint class
  • Lower running cost than a same-capacity non-Most-Efficient model
  • 25-pint class suits a single room, not a full basement
  • No pump variant — gravity drain or manual bucket only
$195.00 street est. — unverified
7

Best for: best compact model for a small room or crawlspace

Frigidaire 22-Pint (FHDD2233Y1)

The smallest certified capacity class on this list, sized for a single small basement room, a crawlspace, or as a supplement next to a larger unit — from a brand with a long track record in home dehumidifiers.

  • Smallest footprint and price on the list; easy to move room to room
  • Established brand with wide parts/service availability
  • ~1,000 sq ft ceiling at moderately damp conditions — undersized for a full basement
  • No pump; manual bucket or gravity drain only
$165.00 street est. — unverified
8

Best for: best mid-size basement

LG 35-Pint (DT351BWR0)

The 35-pint class (current DOE rating — roughly the old 50-pint class) is the sweet spot for a medium basement that's damp but not wet — enough capacity to keep up without paying for a full 50-pint unit you don't need.

  • Right-sized capacity for a medium, moderately damp basement
  • Established major-appliance brand
  • No pump variant; needs a nearby floor drain or bucket emptying
  • Undersized for a large or very wet basement
$235.00 street est. — unverified
9

Best for: best cheap entry-level model

Perfect Aire 22-Pint (3PFD22)

The lowest street price on this list for a certified unit — a reasonable way to try dehumidifying a small space before committing to a bigger, pricier system.

  • Lowest price on the list for an ENERGY STAR-certified model
  • Low commitment if you're not sure how damp the space really is
  • Smallest capacity class; not built for a full basement
  • Budget brand — less established service/parts network than majors

Best for: best HVAC-integrated whole-home system

Healthy Climate 65-Pint Whole-Home (HCWHD-080)

Lennox's whole-home dehumidifier line, ENERGY STAR Most Efficient certified and built to integrate with an existing Lennox HVAC system — worth a look if you're already working with a Lennox dealer for ductwork or a furnace/AC replacement.

  • ENERGY STAR Most Efficient certified 65-pint-class whole-home capacity
  • Designed to integrate with existing Lennox HVAC equipment
  • Highest measured annual energy use in this dataset for its capacity class — verify against current spec sheet
  • Best value only if you're already in the Lennox ecosystem or need new ductwork anyway
