  • Improve Ventilation: Ensure proper ventilation in areas prone to moisture, such as bathrooms and kitchens. Use exhaust fans to expel humid air outside.
  • Seal Air Leaks: Identify and seal air leaks in windows, doors, and walls to prevent the infiltration of outdoor humidity.
  • Use Air Conditioners: Air conditioning systems can help reduce humidity by cooling the air and removing moisture. Ensure your AC unit is well-maintained.

Dealing with Low Humidity

Here is what to know if you think you might be dealing with low humidity in your home:

Common Signs of Low Humidity

If you have noticed any of the following things, your home might be suffering from low humidity:

  • Dry Skin and Irritation: If you and your family members experience dry, itchy skin or irritated eyes, it may be a sign of low humidity.
  • Frequent Static Electricity: The build-up of static electricity, resulting in frequent shocks, can be a sign of low humidity.
  • Cracked Wood Furniture: Wood furniture or musical instruments may show signs of cracking due to lack of moisture in the air.
  • Frequent Sore Throats or Respiratory Irritation: Low humidity can contribute to respiratory issues, leading to more frequent sore throats or irritations.

Problems Associated with Low Humidity

While low humidity might seem preferable, it still can cause a variety of issues in your home:

Dry Skin and Irritation

  • Low humidity can cause dry skin, irritation, and discomfort.

Respiratory Issues

  • Inadequate moisture in the air can lead to respiratory problems, especially for individuals with pre-existing conditions.

Static Electricity

  • Insufficient humidity levels contribute to the build-up of static electricity, potentially damaging electronic devices.

Property Damage

  • Low humidity can cause wood to dry out and crack over time.

Increased Energy Costs

  • Low humidity can make the air feel cooler, leading to increased heating costs in the winter.

How to Increase Humidity in Your Home

If you are dealing with low humidity and are trying to increase the moisture level to fall within the range of perfect home humidity, try:

  • Use a Humidifier: Invest in a humidifier to add moisture to the air. There are various types, including evaporative, ultrasonic, and steam vaporizers. Whole-house humidifiers are also an option. Follow the manufacturer's instructions for placement and operation.
  • Indoor Plants: Incorporate indoor plants, as they release moisture through a process called transpiration, contributing to higher humidity.
  • Open Water Containers: Place open containers of water strategically around your home. The water will gradually evaporate, increasing humidity.
  • Avoid Excessive Ventilation: Minimize excessive ventilation, especially during very dry conditions, as it can remove moisture from


General Tips For Maintaining The Perfect Home Humidity
