Maintaining a comfortable amount of moisture in the air is important for your well-being and for your health. We’ll show you how to lower the humidity in your house when it’s too high to prevent mold from growing in your home.

Humidity in Your Home: How High Should It Be?

Having high humidity in your house isn’t just uncomfortable, it’s also dangerous. Too much moisture in the air creates the perfect environment for mold to grow. When mold gets into the air, it can make you sick and/or trigger allergic reactions. Not to mention the damage it does to your walls and the unpleasant musty smell.

The average humidity in your home should be around 40-60%. To measure the amount of moisture in the air, you can use a hygrometer like this one on Amazon**.

If you’re trying to reduce the humidity in your house as quickly as possible, proper ventilation is your best bet. 

  • In winter, open windows completely for five to ten minutes several times a day and let the fresh air circulate. Turn off your heater while the windows are open, to save energy.
  • In summer, you can keep the windows open for longer, since you don’t have to worry about the temperature dropping too much. When it’s hot outside, it’s best to ventilate your home in the early morning or late evening. During the day, the air outside can be more humid than the air inside. 

Tip: Pay attention to where and how the fresh air is coming into your home. For the best effects, make sure the air can circulate.

Granules can Help Reduce Humidity in Your Home

If ventilation isn’t enough, you can try using different kinds of dehumidifying granules. 

  • Conventional granules are made of calcium chloride, a type of salt that is also often used to de-ice roads and sidewalks in the winter. You can buy them in home goods stores, or online on Amazon**.
  • Chloride-based granules are usually said to be environmentally neutral, but that has been debated by some. Whether or not they are eco-friendly, they are definitely not child or animal friendly. If you feel uneasy, you can buy dehumidifying bags filled with activated bamboo charcoal instead, like these on Amazon**.
  • Wondering how to lower the humidity in your house without buying special products? Some common household items that have a similar effect are rice, kitty litter, and table salt.
  • Be sure to switch out your dehumidifying granules regularly.

Preventative Measures

Just by breathing or sweating, people automatically raise the humidity level in a room. Plants and animals also give off moisture into the air. Through respiration and perspiration alone, an average family of four gives off a whopping five liters of water per day. To help keep the humidity in your house in check, try these tricks:

  • Try to reduce the amount of steam produced while you’re taking a shower by only letting the water run when you need it, and keeping the temperature lower. 
  • When cooking, use lids to cover pots and pans to keep the steam contained. If you have an extractor fan, use it. If you don’t, keep the kitchen door closed and at least one window open, to allow the moisture to escape outside, and not into the rest of your house. 
  • Another idea for reducing the humidity in your house: if you let your laundry air-dry, place your drying rack outside in the garden or on a balcony so that the moisture doesn’t get trapped in your home.
