Best overall for 1,000 sq ft
LG PuriCare 35 Pint
The LG PuriCare 35 Pint leads because it is the only residential model here with app control, a timer, quiet operation, and a stated tank size, plus Energy Star certification. A built-in pump is not stated by the maker, so it suits buyers who can empty the 10.6 pints (1.3 gal) tank or use its listed continuous draining. Compared with the ALORAIR Sentinel HD35PS 35 Pint below, it trades a pump for smarter controls and a lighter 35.1 pound body.

Verdict: The ALORAIR Helios D35 35 Pint is a light, efficient basic pick for a 1,000 sq ft space.
We compared dehumidifiers rated for 800 to 1,200 sq ft using only the specifications makers publish. No unit was handled or measured. Because these models do not state their pint rating basis, the ranking does not use pints per day; it uses features such as pump, Energy Star certification, tank size, controls, weight, and square footage rating. The lead pick is the one that best fits a typical 1,000 sq ft room from the listed specs.
Match the Rating to Your Room and Dampness
Start with the maker's square footage rating. The models here are rated for 800 to 1,200 sq ft, so they fit that range. Dampness matters too: a slightly damp space needs less moisture removal than a wet basement with seepage. The EPA suggests keeping indoor humidity below 60 percent, ideally between 30 and 50 percent. Use a capacity guide to check whether your space is slightly damp, very damp, or wet.
Choose Drainage: Bucket, Gravity, or Pump
A removable bucket works if you can empty it regularly. The LG PuriCare 35 Pint states a 10.6 pints (1.3 gal) tank, while the ALORAIR models here do not state a tank size. For a basement or crawl space, a built-in pump can send water upward to a sink or out a window, which avoids trips to a floor drain. See when a built-in condensate pump is worth it and bucket vs continuous drain for basements.
Look for Controls That Fit Your Routine
Adjustable humidity control and a humidistat let you set a target and let the unit cycle. Automatic restart keeps settings after a power blink, which matters in basements and garages. App control and a timer, found on the LG PuriCare 35 Pint, add scheduling for occupied rooms. Check setting and checking a humidistat and auto restart and humidity settings after outages.
Energy Star and Running Costs
According to ENERGY STAR, certified models pull out as much moisture as a conventional unit of similar size while using about 20 percent less energy, thanks to more efficient coils, compressors, and fans. Among these picks, the LG PuriCare 35 Pint, ALORAIR Sentinel HD35PS 35 Pint, and ALORAIR Helios D35 35 Pint carry the label. See what Energy Star means for running costs.
Placement and Cold-Room Behavior
Leave clearance around the unit so air can circulate, and keep doors and windows closed while it runs. In cool spaces below about 65°F, frost can form on coils; automatic defrost helps the unit cycle off and thaw. Every ALORAIR pick except the ALORAIR Helios MP35 70 Pint lists automatic defrost; the LG PuriCare 35 Pint listing states no defrost feature. See how compressor dehumidifiers behave in cold rooms.
A model rated for 800 to 1,200 sq ft fits a 1,000 sq ft space. Dampness level also matters: a wet basement with seepage needs more moisture removal than a slightly damp living area. The EPA recommends keeping indoor humidity below 60 percent, ideally 30 to 50 percent.
Does a 1,000 sq ft space need a built-in pump?
Not always. A pump helps when you need to move water upward to a sink, out a window, or across a long run. If you can place the unit near a floor drain or empty a bucket, a gravity drain or tank works. The ALORAIR Sentinel HD35PS 35 Pint, ALORAIR Sentinel HD35P 35 Pint and ALORAIR Helios MP35 70 Pint list built-in pumps; for the LG PuriCare 35 Pint a pump is not stated by the maker.
What humidity level should you set?
The EPA suggests keeping indoor humidity below 60 percent, ideally between 30 and 50 percent. In cooler climates during heating season, 30 to 40 percent helps prevent window condensation. Use a built-in humidistat or a separate hygrometer to check the room.
Are Energy Star dehumidifiers worth it for 1,000 sq ft?
Energy Star certified models use about 20 percent less energy than similarly sized conventional units, according to ENERGY STAR. Among these picks, the LG PuriCare 35 Pint, ALORAIR Sentinel HD35PS 35 Pint, and ALORAIR Helios D35 35 Pint carry the label.
Where should you place a dehumidifier in a 1,000 sq ft room?
Place it near the dampest area with clearance around the intake and exhaust, and keep doors and windows closed. Avoid blocking airflow with furniture.
