It’s important to know how to lower humidity in your home. Too much moisture in the air is more than just uncomfortable — it can cause health problems and lead to costly water damage.
The ideal humidity range is 30%–50%. If it’s higher, you’ll feel hot and sticky. High humidity provides an ideal environment for mold and mildew that can damage your health and the surfaces they grow on. Wood can swell, making doors and windows hard to close. Left unchecked, wet wood can deteriorate and attract destructive insects. Metal surfaces will pit and rust. Everything from clothes, drapes, rugs and pets may take on an unpleasant smell.
It’s definitely in your interest to make sure the humidity in your home is at the right level so you can avoid any of these problems. Keep reading to learn more about what causes high humidity and how you can control it.
To control moisture in the home, you need to address the ways it gets in as well as what’s preventing it from venting out.
When considering what causes high humidity in a house, water leaks are a big contributor. They can occur when cracks in walls let groundwater or rainwater seep in. Another example is when pipes slowly leak moisture into the material around them. That water then evaporates and becomes vapor in your home, causing water damage and promoting mold and bacteria as it does so.
Find and repair leaks as quickly as possible.
A dehumidifier is a device that pulls water out of the air, helping you maintain a lower humidity level. You can find one in every price range. To reduce power consumption, look for an energy-efficient dehumidifier that’s certified by ENERGY STAR ®️.
Some people use humidifiers in the summer to feel cooler. But if you already have high humidity, these devices can make it worse.
Most homes have exhaust fans in places where moisture tends to build up. Fans can vent steam over the stove from boiling water or in the bathroom from a hot shower. Be sure to run them while cooking and showering — and for several minutes after finishing to make sure the steam is dissipated.
These devices are a great option for how to reduce humidity in your house, and using energy-efficient fans whenever possible can reduce the amount of electricity you use as well.
The filters on your AC units are meant to capture dirt, dust, pet dander and debris that float in the air and reduce air quality. When these filters get clogged, they also trap moisture, becoming a water wick that creates a perfect environment in which mold and bacteria can thrive. It won’t take long for you to start seeing signs of high humidity in your home.
New filters are more likely to work as designed, so try to replace them regularly. It’ll go a long way toward keeping your indoor air clean and not too humid.
Plants can improve indoor air quality as well as add beauty to your rooms. Some of them are natural dehumidifiers, efficiently drawing moisture out of the air. Here are some of the best plants for reducing the humidity in your home:
Hot showers fill your home with steam. You burn energy heating the water, too. Hot water feels good, but it isn’t healthy for your skin: It can cause dryness, strip off natural oils and worsen certain skin conditions.

Increasing air circulation in your home clears out pockets of humid, stale air and replaces it with fresh.

Moving air also feels cooler, which is a benefit if you have high humidity in your house in the summer.
