Quick answer

To get rid of humidity in your house without a dehumidifier, cut the moisture going in and vent it out: run exhaust fans, cover pots, dry laundry outdoors, fix leaks and use your AC. Check the result with a humidity reader and aim for 30 to 50 percent. Moisture absorber buckets help closets and small spaces, but they cannot dry a whole house.

Free fix vs. permanent fix

Free fix · 15 minutes today, then daily habits

Vent, seal and stop adding moisture

  • Run the bathroom fan during showers and for 20 minutes after
  • Cover pots and use the range hood when you cook
  • Dry laundry outdoors or in a dryer vented outside
  • Fix leaks and keep windows closed on muggy days

How long it lasts: As long as you keep the habits. In a humid climate or a house with a damp basement, the humidity can creep back.

Moisture absorber buckets

Free habits cut the moisture in the air, but damp pockets like closets, cabinets and bathrooms stay still and humid. Absorber buckets collect the water into a tub, so those spots stay drier between airings. They are a low-power sidekick to ventilation, not a replacement for a dehumidifier.

How long it lasts: Each one lasts about a month or two in a closet or small room, depending on the dampness. Then you replace it.

Why it happens

1

Showers, cooking and breathing

A household adds a lot of water vapor every day through showers, boiling water, drying laundry indoors and just breathing.

2

Poor ventilation

A bathroom fan that is rarely used, or a range hood that recirculates air instead of venting outside, leaves the moisture in the house.

3

Muggy weather and open windows

On a humid day, opening windows lets damp air in. When outdoor air holds more moisture than indoor air, ventilating makes it worse.

4

Leaks and a damp basement or crawl space

Slow leaks, wet soil, an uncovered crawl space or a basement floor all release water vapor into the house.

5

An oversized AC

An air conditioner that is too big cools the air fast and shuts off before it removes much moisture, so the air feels cool but clammy.

Do these in order, starting with the simplest.

  1. Measure first

    Tool used: Hygrometer

    Put a humidity reader in the rooms that feel damp and check it morning and evening. Aim for 30 to 50 percent. Over 60 percent for days means mildew can grow.

  2. Vent at the source

    Tool used: Exhaust fans

    Run the bathroom fan during a shower and for 20 minutes after. Use the range hood when you cook, put lids on pots and take shorter, cooler showers.

  3. Stop drying laundry indoors

    Hang clothes outside, or use a dryer that vents outdoors. Check the dryer vent hose for leaks and lint.

  4. Use the AC and shut windows when it is muggy

    Running the AC removes moisture while it cools. Keep windows closed when the air outside is more humid than the air inside. Set the AC fan to Auto, not On, so water on the coil drains instead of blowing back into the house.

  5. Fix leaks and move water away

    Repair drips under sinks, clear gutters and make sure downspouts drain away from the foundation. Cover bare soil in a crawl space with plastic sheeting, which a pro can do.

  6. Dry the damp pockets

    Tool used: Moisture absorber buckets

    Open closet doors, pull furniture a few inches off outside walls, and set absorber buckets in closets, cabinets and the bathroom. Check them every few weeks, and replace them when the crystals are gone.

When free fixes aren't enough

Ventilation and habits work when the moisture comes from daily life. They do not work when it comes from the ground, a wet basement or muggy weather. If your reader still shows above 60 percent after two weeks of the free steps, a dehumidifier removes far more water than any bucket can. Absorbers still earn their place in closets, cabinets and small rooms, and they need no power. They hold a small amount, fill up and then need replacing. If you see mold, smell mustiness or find water stains, fix the source first.

Moisture absorber buckets

Fixes: damp, musty corners, closets and small rooms

Look for: Calcium chloride crystals in a sealed tub or hanging bag; A built-in tray that catches the liquid so it cannot spill easily; Coverage sized for a closet, bathroom or small room; A fragrance-free option.

Who it's for
Renters and anyone with a closet, bathroom or small room that stays damp and no space for a dehumidifier.
Honest downside
The whole house is above 60 percent humidity, where you need a dehumidifier or an AC fix. Keep the liquid away from kids and pets, since it is a salty brine.

How we picked: How we picked: this page is based on public indoor-humidity and mold guidance, home ventilation basics, and what owners report in reviews of moisture absorbers. We do not test products by hand.

Room by room: how to get rid of humidity in the house naturally

Bathroom: fan on during and after showers, door open afterward. Kitchen: range hood on, lids on pots. Bedroom: furniture off outside walls, windows open a few minutes a day. Basement: gutters clear, downspouts directed away, no clothes drying. Closets: doors ajar and a bucket on the shelf. Each room has its own source, so one habit does not fix all of them.

When to open windows and when to keep them shut

Open them when the air outside is drier than the air inside, usually on a cool, dry morning. Keep them shut on warm, muggy days, because outdoor air then adds moisture. A cheap humidity reader indoors and a weather app outdoors tell you which case you are in.

What to skip

Bowls of salt or rice, and houseplants

Bowls of salt, rice or baking soda absorb too little to matter in a room. Houseplants release moisture instead of removing it. Skip them and put the effort into venting.

Frequently asked questions

How do I get rid of humidity in my house naturally?
Vent steam at the source, dry laundry outside, fix leaks, keep windows closed on muggy days, use the AC, and give closets and furniture room to breathe. These cost nothing, and a humidity reader shows whether they are working.
What humidity level should my house have?
Public health guidance suggests keeping indoor humidity between about 30 and 50 percent, and below 60 percent. Above that, mold and dust mites do better, and below it the air can feel dry.
Does air conditioning remove humidity?
Yes. Cold coils pull water out of the air as they cool it. An AC that is too big may shut off before it removes much, which leaves the air cool and clammy. If your home feels sticky even with the AC on, the size or the fan setting may be the cause.
Do moisture absorbers really work?
They work in small, closed spaces like closets and cabinets, where they pull water out of still air. They are not strong enough to dry a whole room or house. Use them alongside ventilation.
