Tips to Lower the Indoor Humidity in Your House

Indoor Humidity

In the quest for a comfortable and healthy home environment, managing indoor humidity levels is a key factor. Excessive humidity can lead to a range of issues, from discomfort and musty odors to more serious problems like mold growth. 

In this article, we’ll explore practical and easy-to-implement tips to help you lower the indoor humidity in your house and create a more pleasant living space.

  • Ventilation is Key

Proper ventilation is the foundation for controlling indoor humidity. Ensure that your home is well-ventilated by regularly using exhaust fans in bathrooms and kitchens. Additionally, consider installing ventilation systems to promote air circulation and reduce the buildup of moisture. Opening windows on mild days can also help to exchange humid indoor air with drier outdoor air.

  • Use Dehumidifiers Wisely

Dehumidifiers are powerful tools in the battle against excess humidity. Place them in high-humidity areas like basements, crawl spaces, or laundry rooms to efficiently remove moisture from the air. Opt for a dehumidifier with a built-in hygrometer to monitor humidity levels and set the device to maintain an optimal range, typically between 30-50%.

  • Repair Leaks and Seal Gaps

Undetected leaks and gaps in your home can contribute significantly to increased humidity levels. Regularly inspect your plumbing, roof, and windows for any leaks, and promptly repair them to prevent the infiltration of moisture. Seal gaps and cracks in walls, windows, and doors to keep humid air from entering your home and causing an imbalance in humidity levels.

  • Mindful Water Usage

Everyday activities like cooking, showering, and doing laundry contribute to indoor humidity. Be mindful of water usage to prevent unnecessary moisture buildup. Use lids while cooking to contain steam, run exhaust fans during and after showering, and ensure that your clothes dryer is properly vented to the outside. These small adjustments can make a significant impact on reducing indoor humidity.

  • Monitor Indoor Plants

While indoor plants are a beautiful addition to any home, some can release moisture into the air through a process called transpiration. If you notice high humidity levels, consider relocating or reducing the number of plants in high-humidity areas. Alternatively, place moisture-absorbing materials, like silica gel, near your plants to counteract excessive humidity.

  • Check and Maintain HVAC Systems

Your heating, ventilation, and air conditioning (HVAC) systems play a crucial role in humidity control. Regularly inspect and maintain your HVAC systems, including cleaning or replacing filters, to ensure optimal performance. If your HVAC system has a humidification feature, disable it during humid seasons to prevent unnecessary moisture release into your home.

  • Utilize Natural Dehumidifiers

Certain household items act as natural dehumidifiers. Placing bowls of rock salt or silica gel in damp areas can help absorb excess moisture. Additionally, using moisture-absorbing bags or containers in closets and cabinets can prevent musty odors and protect items from humidity-related damage.


Lowering indoor humidity is not only about creating a more comfortable living space but also about safeguarding your home from potential issues like mold and mildew. By incorporating these practical tips into your daily routine, you can take control of your indoor environment and enjoy the benefits of a healthier and more pleasant home. Remember, maintaining balanced humidity levels is a proactive step towards a happier and more comfortable living space.
