A musty smell in a closet, condensation building up on windows, that general stickiness in the air after a rainy week — these are classic signs an apartment needs a dehumidifier, not just better airflow. Unlike a portable AC, most small dehumidifiers don’t even need a window vent kit; you just plug them in and empty the tank every couple of days. We compared current independent testing to find the picks that actually make sense for apartment-sized rooms.
What to look for if you’re renting
Pint capacity tells you how much moisture a unit removes per day — for a single bedroom or small living room, 20–35 pints is usually plenty, while anything larger starts to make sense only for an open studio or a genuinely humid climate. Tank size matters more day-to-day than most people expect: a small tank means emptying it constantly, so look for one rated to hold at least two days’ worth of moisture if you don’t want it to become a chore. If noise matters (say, it’ll run in your bedroom overnight), check for models specifically tested as quiet. And if you’d rather not deal with a tank at all, look for one with a continuous drain hose option, so it can run unattended into a sink or floor drain.
Our top picks for 2026
Midea Cube 20-Pint Dehumidifier
Repeatedly named a top pick across independent test labs for its reliability — testers specifically noted smaller-capacity units from other brands had far more reported issues. A compact, boxy design that’s easy to tuck into a corner.
Good for: a single bedroom or small living room, with reliability that holds up over time
Eva-Dry EDV-1100
A genuinely compact, low-power unit, easily fits on a shelf or nightstand. Not built for large or very humid rooms, but for a closet, bathroom, or small bedroom, it’s a cheap way to keep dampness in check.
Good for: closets, bathrooms, or small rooms with mild humidity issues
GoveeLife 50-Pint Dehumidifier
Rated a top overall pick in 2026 testing for handling rooms of all sizes well, with a large enough capacity to keep up with an open-concept studio or particularly humid apartment without constant tank-emptying.
Good for: larger or more open layouts, or genuinely humid climates
WiseDry Desiccant Dehumidifier
Skips the compressor entirely — it’s silent, needs no outlet to run once charged, and is small enough to drop inside a closet, gun safe, or cabinet where a full-size unit wouldn’t fit. Recharges by plugging in for 8–12 hours every few weeks.
Good for: enclosed spaces like closets and cabinets, not whole rooms
Frequently asked questions
Do I need a dehumidifier if I already have a portable AC?
Not necessarily — many portable ACs include a basic dehumidifying mode. A dedicated dehumidifier makes more sense if humidity (not heat) is your main issue, or you want it running in a different room than your AC. See our guide to portable air conditioners for apartments if cooling is the bigger priority.
How often do I need to empty the tank?
Depends on the unit’s capacity and how humid your space is, but most apartment-sized dehumidifiers need emptying every 1–3 days. Models with a continuous drain hose option can skip this entirely.
Will a dehumidifier get rid of a musty smell?
Often yes, since musty smells are usually caused by excess moisture supporting mold or mildew growth. Running a dehumidifier in the affected space for a few days typically helps, though a deep clean may still be needed if mold has already set in.
Can I run a dehumidifier overnight in my bedroom?
Yes, as long as it’s a model specifically noted as quiet — most compressor units run somewhere around 40-50 decibels, similar to a quiet office, which is generally fine for sleeping.
