The best dehumidifiers for a basement
Ranked on drainage before capacity, because the machine that cannot reach your drain is the wrong machine at any pint rating.

The short answer
For most US basements: a 50-pint DOE-rated compressor unit with continuous drainage, drawing around 488 W. If the drain is below the machine, gravity is enough and the cheapest unit wins. If it is above, you need a built-in pump, and that single fact eliminates about half the market.
Start with the drain, not the pint number
Every basement dehumidifier roundup you will read opens with capacity. That is the wrong order. Capacity is a spectrum - a 50-pint unit in a room that needed 30 works fine, it just idles more. Drainage is binary. A machine with no pump cannot move water uphill, and there is no setting, no accessory and no technique that changes that.
So go and look first. Stand where the unit will live and find the nearest place water can go: a floor drain, a sump pit, a laundry standpipe, a utility sink, a window well. Then note whether it is above or below the machine's drain port, which sits a few inches off the floor on most portables.
- Below the port, within hose reach - you need nothing but a hose. Buy the cheapest 50-pint unit with a threaded outlet and spend the difference on nothing.
- Above the port - you need a built-in condensate pump. This is most finished basements and nearly every crawl space.
- No drain at all in the room - a pump plus a run to a sink, a stack or out through a rim joist. Or an external condensate pump, which is a separate purchase and a separate failure point.
Then the capacity, and what the number means
In June 2019 the US Department of Energy changed the dehumidifier test procedure. Units are now tested at 65F rather than 80F, because a basement in July is nearer 65F than 80F and the old figure flattered every machine on the market. Cooler air holds less water, so the same hardware now reports a smaller number. ENERGY STAR's published correlation maps an old 70-pint rating to 40 to 45 pints new, and an old 90 to 55.
This is why a 2018 buying guide recommending a 70-pint unit and a 2026 one recommending a 50-pint unit are giving the same advice. It is also why some listings still lead with a saturation figure measured at 95F and 90% RH, which is a hot tropical condition a US basement essentially never reaches. One crawl space unit covered on this site is sold as 113 pints and certified at 36.33. Both numbers are true; they are 3.1 times apart. The full explanation.

Midea
Midea Cube 50 Pint Dehumidifier
Best for: A basement you visit once a month
The only unit here that solves the real basement problem, which is not capacity but where the water goes when you are not standing next to it.
Average draw
487 W
Computed from the ENERGY STAR certified entry for Midea MAD50S1QWT-A, the 50 pt / 4,500 sq ft Cube without a pump: 49.67 pt/day at IEF 2.01 L/kWh. Midea's own US product page confirms MAD50S1QWT-A is this configuration. Midea publishes no wattage on the Amazon listing or on that page.
What is good
- The body separates, so the tank half can sit lower than the compressor half and the hose gets a genuine downhill run
- Certified at 49.67 pt/day, which is a real 50-pint machine rather than a saturation number
- IEF 2.01 L/kWh puts it exactly on the median for the 50-pint class - neither a bargain nor a penalty
- Wi-Fi that tells you it has stopped, which is the only smart feature that matters in a basement
What is not
- No pump, so the drain has to run downhill the whole way
- Midea publishes no wattage anywhere, so the 487 W above is computed rather than quoted
- The 4,500 sq ft coverage claim is marketing, not a spec - see the sizing guide
Who it is for
Someone with a floor drain, a sump, or a window well lower than the machine, who wants to set it once and stop thinking about it.
Skip it if
Skip it if the only drain in the room is higher than the unit. Without a pump, gravity is the entire drainage system, and no setting fixes an uphill hose.
Midea
Midea Cube 50 Pint Dehumidifier with Pump
Best for: A basement whose only drain is upstairs
The stacking Midea Cube with a condensate pump added, which is the difference between a hose you can run and a hose you cannot.
Average draw
487 W
Computed from the ENERGY STAR certified entry for Midea MAD50PS1QWT-A, the pump variant of the same platform: 49.67 pt/day at IEF 2.01 L/kWh. The listing prints the unsuffixed MAD50PS1QWT, so the certified string carries a suffix the box does not; every Midea 50-pint revision in the certified list, pump or not, computes to 487-490 W, so neither the suffix nor the pump moves the number meaningfully. The pump itself only runs in bursts.
What is good
- Pump means the destination can be higher than the machine - a laundry sink, a window, a stack
- Identical DOE capacity and IEF to the non-pump Cube, so the pump costs you nothing in efficiency
- The split body still works, so you can also run it on gravity and keep the pump as the backup
- Certified 49.67 pt/day, an honest 50-pint rating
What is not
- Costs more than the identical machine without the pump
- A pump is one more thing that can fail, and when it does the unit stops rather than overflows
- No published wattage from Midea - the figure above is computed
Who it is for
Anyone whose drain is above the floor. That is most finished basements and nearly every crawl space.
Skip it if
Skip it if you already have a floor drain within hose reach and below the machine. You would be paying for a pump you will never switch on.
Frigidaire
Frigidaire 50 Pint Dehumidifier with Wi-Fi
Best for: A Frigidaire with a drain below it
Frigidaire's current no-pump 50-pint: certified by exact model number, Wi-Fi equipped, and a 2.7 gallon bucket that is among the largest of any 50-pint unit we track.
Average draw
488 W
Computed from the ENERGY STAR certified entry for Frigidaire FHDD5034Y1 - the same model number as this listing: 49.71 pt/day at IEF 2.01 L/kWh. Frigidaire's Canadian product page states 115 V, 8.8 A and 470 W; those figures do not reconcile with each other and are nameplate rather than average values, so 488 W is the running-cost figure.
What is good
- Exact certified model match, so the 488 W figure describes this machine rather than a sibling
- 2.7 gallon bucket - roughly ten hours of condensate at full rated capacity if you ever run it without a hose
- Continuous drain, three fan speeds and operation down to 41F
- Wi-Fi and the Frigidaire app for scheduling and remote control
What is not
- Gravity only. The drain must be below the machine
- The Wi-Fi depends on Frigidaire's app remaining supported
- Frigidaire's own published wattage and amperage do not agree with each other
Who it is for
Someone with a floor drain who wants a certified, well-documented 50-pint unit and has a use for scheduling.
Skip it if
Skip it if the only drain is above the machine. That is the one job a gravity unit cannot do, whatever else it has.
Frigidaire
Frigidaire 50 Pint Dehumidifier with Pump and Wi-Fi
Best for: Seeing why a nameplate is not a running cost
Frigidaire's own documents give two different wattages for this machine and the certified record gives a third - which makes it the clearest case on the site for trusting the computed average over any printed figure.
Average draw
490 W
Computed from the ENERGY STAR certified entry for Frigidaire FHDP5033Y1 - the same model number as this listing: 49.95 pt/day at IEF 2.01 L/kWh. Frigidaire's own figures do not agree with each other: its US specification sheet states 115 V, 5.5 A and 620 W, while its Canadian product page states 115 V, 8.8 A and 470 W. Those are nameplate figures, not averages, and they do not reconcile - use 490 W for running cost.
What is good
- The retail model number is exactly the certified one, so the 490 W figure is a direct match rather than a family estimate
- Pump discharges upward into a sink or out of a window, with bucket and continuous-drain modes as well
- Stated to keep working down to 41F, which matters in an unheated basement in shoulder season
- Wi-Fi with the Frigidaire app, plus Alexa and Google Home
What is not
- Frigidaire's two published wattages disagree - 620 W and 470 W - and neither is the running-cost figure
- No pump lift or hose run is stated on the listing or on either Frigidaire page we checked
- The Amazon listing itself is sparse; the useful detail lives on Frigidaire's own pages
Who it is for
Someone who wants a pump and Wi-Fi from a maker with a certified exact-model record, and who will size the circuit from the higher of the maker's figures.
Skip it if
Skip it if your pump route is long or tall. Frigidaire states no lift, where GE and Quilo state 15 feet in writing.
GE
GE 50 Pint Dehumidifier with Pump
Best for: A lift and a hose length, both in writing
GE states both numbers a pump buyer needs - 15 feet of vertical lift and a 16 foot hose - which is the most complete pump specification of any 50-pint unit we track.
Average draw
Not published
Not published by GE. The ADHE50 series does not appear by name in the ENERGY STAR certified list and this listing makes no ENERGY STAR claim - its predecessor did. The certified 50-pint class runs 443-490 W with a median of 488 W; adding a pump does not change capacity or IEF on the certified units that have one.
What is good
- States a vertical lift and a hose length separately - the two constraints a pump route actually has
- The listing tells you when to choose the pump model, which is more guidance than most makers give
- Humidistat down to 30 percent, a 24-hour timer and Smart Dry fan control
- Bucket-full alarm and clean-filter alert
What is not
- No ENERGY STAR certification claimed, so there is no certified figure to compute running cost from
- 15 pint bucket is smaller than several rivals, which matters if the pump ever stops
- 5,000 sq ft coverage claim, up from 4,000 on its predecessor for the same capacity
Who it is for
Someone whose drain is up a wall or across a room and who wants the limits of the pump stated before buying rather than discovered after.
Skip it if
Skip it if the discharge point is more than 15 feet above the unit or needs more than the included 16 feet of hose. Those are the limits GE put in writing.
What these will cost you to run
Almost nobody publishes a dehumidifier's power draw. The inputs are public though: the ENERGY STAR certified product list gives every certified model's capacity at the DOE test condition and its Integrated Energy Factor in liters per kWh, and those two numbers give you the watts directly.
A median certified 50-pint unit, running 12 hours a day

$65.38
per month, 24 h/day
Rate is the US residential average of 18.34 cents/kWh from the EIA Electric Power Monthly, June 2026. Yours will differ - use the calculator.
Across 164 certified 50-pint models the range is 443 to 490 W, so any 50-pint machine will land inside about ten percent of that figure. The bigger variable is your electricity rate - Nevada is 13.11 cents per kWh and Hawaii is 52.72, a four-fold spread on the same machine. Work out your own number.
One thing that matters more than any of this
A dehumidifier is not a waterproofing system. If the basement floor is wet after rain, if the walls are visibly damp at the base, or if there is efflorescence on the block, the water is coming in from outside and a machine that removes 50 pints a day is bailing rather than fixing. Gutters, grading and a working sump come first.
Where a dehumidifier earns its keep is the ordinary case: a basement that is structurally sound but sits at 65 to 75% relative humidity all summer because it is below grade and cool. The EPA advises keeping indoor relative humidity below 60 percent, ideally between 30 and 50. Getting from 70 to 50 is exactly what these machines do, and it is the difference between storage that survives and storage that smells. If the room above that basement has a wood floor, the humidistat's lower limit matters as much as its capacity - the best dehumidifiers for hardwood floors.
What we would skip
Any thermoelectric mini unit, at any price
A Peltier mini removes about one pint a day. A basement machine removes fifty. They appear on the same search results page and the mini costs a tenth as much, which is why this is the single most common mis-purchase in the category. It is not a small dehumidifier; it is a different class of device.
A gravity-only unit when your only drain is above the floor
Half the units in any listing have no pump. If the destination is a laundry sink or a window, a gravity machine is a bucket you carry twice a day forever - and you will stop, and then the basement is damp again. Work out pump or gravity before you look at a single price.
How we picked
- Certified capacity at the post-2019 DOE test condition, not the saturation figure on the front of the box.
- Drainage options, ranked: pump beats gravity beats bucket, because it removes the constraint rather than working around it.
- Average power draw, computed from the ENERGY STAR certified list where a named entry exists, and stated as a class band where it does not.
- Whether the manufacturer publishes anything checkable at all. A maker that prints a wattage is telling you something about how it expects to be judged.
- We did not run any of these. No chamber, no meter, no shelf of returned boxes.
We did not test these units. The full criteria and their weighting are on the methodology page.
