High indoor humidity levels can cause problems in the home. You’ll feel warmer than the actual air temperature when there’s extra moisture in the air. Mold and mildew also thrive in humid air, which triggers allergies and respiratory problems. According to the National Sleep Foundation, you’ll sleep better when indoor humidity levels are between 30 and 50%. Read on to learn four tips to help lower the humidity in your home.
Lifestyle Changes to Lower the Humidity in Your Home
Your daily activities around the house could be increasing your home’s humidity. Taking long, hot showers is one cause of high indoor humidity. Try to limit your showers to 2-3 minutes and run cooler water.
Overwatering your indoor plants causes extra moisture to evaporate into the air and can also cause mold and mildew. Give your plants the right amount of water at the right time.
Lower the Humidity in Your Home with Exhaust Fans
Exhaust fans are a simple tool to lower the humidity in your home. Every time you bathe or shower, turn on the exhaust fan. While cooking, turn on the range hood’s exhaust fan. Make sure the fan vents to the outdoors, not your attic. If the vent empties into your attic, the moisture will remain in your home.
Cover the Crawlspace
If your home has a crawlspace, moisture from the ground can get inside your living areas. Cover the entire ground area of the crawl space with polyethylene sheeting as a vapor barrier.
These are inexpensive plastic sheets, and it’s easy to spread them over flat surfaces. Be sure to extend the sheeting up the sides of the crawlspace, too. Check on these barriers once a year to make sure they’re still in place.
Use a Dehumidifier
A dehumidifier is one of the best tools you can use to lower the humidity in your home. Portable dehumidifiers are ideal for rooms up to 400 square feet. Make sure to empty the reservoir every time it’s full.
There are also whole-house dehumidifiers that attach to your heating and cooling system to control humidity. A whole-house dehumidifier connects with the condensation drain of your air conditioner to drain the moisture that’s removed from your home’s air. They’re ideal for bigger houses, homes with basements, and people with chronic allergies triggered by mold or dust. A whole-house dehumidifier should be installed by a professional technician.
