Your humidity level will impact the comfort level of your home much more than temperature and other factors. If you feel hot and sticky at home, then you’ll need to know how to fix it.

If you don’t have one of the best humidifiers at home, then you’ll want to learn a DIY method. Here’s how to reduce humidity in the house without a dehumidifier!

What Makes Indoor Humidity Become High?

Humidity inside is caused by having moisture in the air. It can come from bad insulation, ventilation, and fixtures (such as the shower). You’ll want to correct the main issue in your home to prevent more moisture build-up in the future.

There are severe problems that come with a lot of moisture. You risk getting sick, having dry skin, damaging your home’s wood or paint, and even growing mold.

Luckily, it’s very cheap to fix many of these problems. However, you’ll want to keep reading to find out all the best ways to reduce humidity in the home without dehumidifier.

Importance of Controlling Humidity at Home

You’ll want to control humidity at home. You and your family will feel more comfortable, and you won’t have to deal with issues like mold. Plus, you’ll notice an improvement in everyone’s health.

  • Comfort
    Humid conditions make us feel awful. This is because there’s so much moisture in the air that your sweat can’t evaporate. That leads to the “sticky” feeling we all hate and makes it impossible to cool ourselves down. Reducing humidity will therefore make you feel more comfortable.
  • Health
    Without the humidity, you’ll also feel much healthier at home. Your skin won’t be dry and cracking, you won’t be breathing in mold, and you won’t be as likely to get sick. Bacteria thrives in humid conditions, meaning you want to avoid them when possible.
  • Static Electricity and IT Equipment Failure
    Humid air can make its way into a computer or other electronic equipment. If it turns back into water, you could have a lot of issues! Plus, you’re more likely to shock someone after walking on the carpet. Likewise, you may shock yourself when you grab a door handle or other metal object.
  • Enhanced Efficiency
    If you’re receiving high electric bills after a humid month, the moisture in the air could be what’s to blame. Energy loss frequently happens when there’s a lot of water in the air to deal with.
  • Deterioration of Materials in the House
    Finally, humidity can cause wood to warp, paint to peel, and mold growth. All of these issues can damage various materials in the house and lead to structural harm.

Reducing Humidity Without Using a Dehumidifier (Natural Ways)

In the Home

First, you’ll want to start by reducing the amount of time you spend showering. Long showers cause water to build up in the room, which then spreads to the rest of your home.

Next, you’ll need to start ventilating your home more efficiently. Place fans inside the home and open all of your windows. If it’s hot inside, use the fan to blow the hot air out the window. If it’s cool enough, then have the fan blowing into the rooms. It helps if you create a “path” for air to follow.

For example, open windows on the opposite sides of the room. This allows air to flow through the middle, giving you a nice breeze while the humidity is whisked outside.

In the Basement

There are a few simple ways to reduce the amount of humidity in the basement when you don’t have any windows down there. First, try setting out a few large bowls of kitty litter. In smaller basements, the litter will suck the moisture from the air. (Make sure your cat can’t get to them!)

Next, check the basement for leaks. Repairing any pipe or foundation leaks you find will prevent excessive moisture from entering the basement. You also may want to check any washing or drying machines in the basement- the washer especially.

Finally, start decluttering. Any storage you have down there blocks the flow of air and traps moisture.

In the Grow Room or Tent

In the growing room, make sure to avoid overwatering your plants. You may also want to place a cover on the soil since this helps keep the moisture trapped in the dirt. If you have the space, a fan will assist with circulation.

Next, make sure to space out your plants. If they’re crowded, moisture tends to build up in those areas. You can rearrange your plants or remove a few from the grow space.

People Also Ask (FAQ)

Does baking soda remove humidity?

Baking soda removes moisture- so it also removes humidity from the home. It’s cost-effective and easy to use. Just pour some into a bowl and place it around the home.

Do fans lower humidity?

Yes, they work great at this. The moving air evaporates the humidity or sends it outside. Plus, the fan will allow sweat to evaporate too- making you feel cooler.


It’s easy to reduce humidity in the basement and home. All you need is more ventilation. However, you will want to find where the problem is stemming from- usually, leaking pipes and showers are to blame.
