A 35 pint dehumidifier is the right size for the most common dehumidifier problem: a basement or finished lower level between 800 and 1500 square feet that runs musty in summer and clammy in winter. The Department of Energy changed its testing standard in 2019, which reclassified what used to be 50 pint units down to 35 pints on the new sticker. Real-world extraction did not change; the test temperature did. After looking at 14 current 35 pint models for basement, crawl space, and finished living-area use, these five stood out for pump design, tank capacity, low-temperature operation, and compressor reliability. The lineup covers pump-equipped picks for hard-to-drain spaces, a quiet finished-room model, and one crawl space option for sealed under-floor use.

| Dehumidifier | Pump | Tank | Coverage | Warranty |
|---|---|---|---|---|

| hOmeLabs HME020031N | No | 1.6 gal | 3000 sq ft (rated up) | 2 years |
| Midea Cube 35 | Optional hose | 4.7 gal (Cube design) | 1500 sq ft | 1 year |

Frigidaire FFAP3533W1, Best Overall
Frigidaire’s 35 pint with built-in pump is the default pick for a basement that needs continuous drainage and lacks a gravity-friendly drain point. The pump pushes water up to 16 feet vertically and across long horizontal runs, which covers most basement-to-laundry-sink or basement-to-utility-sink layouts.
The unit pulls 35 pints per day at the 2019 DOE rating (65 degrees, 60 percent RH), which translates to roughly 50 pints at 80 degrees and 80 percent RH (the way the same unit would have been rated before 2019). The 16.9 pint tank is one of the largest in the class, and the humidistat reads in 5 percent increments down to 35 percent target.
Trade-off: the pump adds noise during the brief pump-out cycle (every 20 to 40 minutes during heavy extraction) and the pump itself has a 7-to-10 year typical life. Replacement pumps are available as a service part for about 60 dollars.
hOmeLabs HME020031N, Best Budget
hOmeLabs built the brand on a clean, simple dehumidifier at a low price, and the 35 pint stays true to that pitch. No pump, no Wi-Fi, no app, just a 1.6 gallon tank, a humidistat, and a continuous-drain hose connection on the back.
The compressor is rated to 41 degrees with hot gas defrost, which makes it usable in a cool basement that other budget brands skip. The 2-year warranty is unusually long for a sub-300 dollar dehumidifier, and the parts (filter, water tank, drain plug) are cheap and available.
Trade-off: at 44 decibels it is louder than the finished-room picks below. In a basement that is the point (you want airflow), in a bedroom it is too loud for sleeping near.
Midea Cube 35, Best for Finished Rooms
Midea’s Cube is a different physical design than every other dehumidifier on the market: a stacked-tank tower that expands vertically for a 4.7 gallon water reservoir, then collapses to a compact base when you want to wheel it across the room. The tank capacity means you can run the unit for two or three days without emptying.
35 pints per day, 38 decibels in low mode (quietest in this lineup), and Wi-Fi control through the Midea app for scheduled operation. The Cube is the pick for a finished basement living room, a home gym, or a craft room where appearance and noise both matter.
Trade-off: the stacked-tank design costs more (around 380 dollars) than a conventional 35 pint, and the expandable mechanism is the part most likely to fail in year 5. For a hidden utility-area install, save the money and buy the Frigidaire.
Aprilaire E035, Best for Crawl Spaces
Aprilaire builds whole-home and crawl-space dehumidifiers and the E035 is their entry size. It is tank-free (continuous drain only) and uses a small built-in pump for vertical lift. The body is rated for 41-degree operation with a hot gas defrost and ships with a corrosion-resistant aluminum coil for sealed-crawl use.
The 5-year warranty is the longest on this list and covers the full unit, not just the sealed system. Coverage is rated for 1500 square feet of basement or crawl space, and the unit can duct into adjacent zones with optional collars.
Trade-off: the Aprilaire is over twice the price of a Frigidaire (around 850 dollars) and requires a hardwired or dedicated outlet install. It is the right call for a finished sealed crawl space, overkill for a typical basement.
Honeywell TP30AWKN, Best for Smaller Rooms
Honeywell’s 30-to-35 pint TP30AWKN covers up to 1000 square feet, which fits a one-bedroom apartment, a small basement, or a single damp room rather than a whole lower level. The smaller footprint (about 14 inches wide) fits a closet or a tight utility area where a Frigidaire would not.
The 1.0 gallon tank is smaller than the others, which encourages continuous-hose use. Run noise is 42 decibels, between the Cube and the Frigidaire.
Trade-off: at 1000 square feet of coverage this is the smallest unit on the list, and stretching it to a 1500 square foot basement leaves it running constantly during humid weeks. Match the unit to the space.
How to choose
Match pint rating to space and dampness
Light dampness (musty smell, no visible water) at 1000 to 1500 square feet wants 35 pints. Heavy dampness or larger spaces want 50 pints or more. Crawl spaces under 1000 square feet are a special case and benefit from a dedicated crawl-space unit even at smaller pint ratings.
Pump for hard-to-drain locations
If your unit sits more than 4 feet below the nearest drain point, buy the pump. Hauling a 1 gallon tank up basement stairs three times a day gets old in week one and stops happening by week three.
Low-temperature operation matters in cold spaces
A unit rated only to 65 degrees ices up and runs poorly in a 55 degree basement. Look for low-temperature operation rated to 41 degrees with hot gas defrost (not just timer defrost) if your space runs cold.
Compressor warranty is the real warranty
The 1-year limited warranty covers everything but breaks first. The sealed-system or compressor warranty (5 to 10 years) covers the part that costs more than the rest of the unit combined. Buy a brand with at least a 5-year compressor warranty for any room you care about.

A 35 pint dehumidifier covers the typical American basement, and the Frigidaire FFAP3533W1 is the safe default thanks to its pump and tank. The hOmeLabs HME020031N is the budget pick that does not feel like a compromise, and the Midea Cube earns its spot when the unit sits in a room people use. Pick based on drain access and noise tolerance, not on pint sticker alone.
Frequently asked questions
Is 35 pints enough for a basement?+
For a basement under 1500 square feet with moderate dampness (you can smell musty air but no visible water), 35 pints per day is the right size. For a damp basement (visible water marks, mold spots) or anything over 1500 square feet, step up to a 50 pint unit. The DOE rating on a 35 pint unit corresponds to a higher real-world capacity in a humid basement than in a 70 degree test chamber, so do not undersize based on square footage alone if the space runs cold.
Pump or no pump on a 35 pint?+
If your dehumidifier sits below a floor drain or near a window where a gravity drain hose works, skip the pump. If the unit sits in a basement corner and the drain is across the room or up a flight of stairs, the built-in pump is worth the 60-to-80 dollar premium. Pumps push water vertically up to 16 feet and let you run the unit continuously without emptying the tank, which is the entire point of buying a dehumidifier.
How big should the water tank be?+
A 35 pint unit usually ships with a 0.8 to 1.7 gallon tank. In a typical damp basement the unit pulls 1 to 2 gallons per day, so a 1.7 gallon tank means one daily empty and a 0.8 gallon tank means two or three. If you cannot drain to a hose, larger tank wins. If you can drain continuously, tank size does not matter.
Should I leave a dehumidifier running 24/7?+
Yes, on a humidistat. Set the target to 45 to 50 percent relative humidity and let the unit cycle on and off automatically. Continuous running with no humidistat wastes electricity, dries the room below comfortable levels, and shortens compressor life. Modern 35 pint units sip about 4 to 5 amps when running and 0 amps when the compressor is off, so an automatic cycle costs roughly 15 to 30 dollars per month on a basement that needs steady drying.
Do dehumidifiers work in cold basements?+
Yes, but with reduced capacity below 65 degrees. A 35 pint unit rated at 65 degrees pulls roughly 20 to 25 pints per day at 55 degrees because the cold coil ices up more often and the unit spends more time in defrost mode. For a 50 to 60 degree crawl space, look for a unit with low-temperature operation rated to 41 degrees, which uses hot gas defrost rather than a timer.
