Controlling humidity levels in your home is essential for both your health and the well-being of your home. High humidity can grow mold, while low humidity can cause dry skin and respiratory issues.

To maintain a healthy humidity level, consider investing in a dehumidifier or humidifier, depending on your needs.

Regularly opening windows and doors for proper airflow can also help regulate humidity levels. Monitoring your humidity levels and taking the necessary steps to control them can create a comfortable and healthy living environment for you and your loved ones.

Dehumidifiers control humidity levels through a combination of mechanisms designed to extract excess moisture from the air: 

  • They draw in humid air through the intake vents, passing it through a set of cold coils and turning it into water droplets.
  • The condensed water droplets are collected in a reservoir within the dehumidifier. Depending on the model, the collected water may need to be manually emptied from the reservoir periodically.
  • Once the moisture is removed from the air, the now drier air is reheated by passing it over warm coils called condenser coils. The warm air is then released back into the room but with a reduced moisture content.
  • Many dehumidifiers are equipped with a built-in humidistat, which is a sensor that measures the humidity level in the room.
  • Dehumidifiers also have a fan that circulates the air within the room. The fan draws in air and directs it over the evaporator and condenser coils, facilitating the dehumidification process. The fan also helps to evenly distribute the drier air throughout the room.

Protecting Belongings

Dehumidifiers are instrumental in protecting furniture, electronics, and valuable items from the damaging effects of excessive moisture.

High humidity levels can wreak havoc on these items, causing deterioration, warping, corrosion, and other forms of damage. By effectively controlling humidity, dehumidifiers provide several mechanisms to safeguard these possessions.

Excessive moisture can seep into furniture, causing the wood to swell, warp, or develop mold and mildew. It can also corrode metal components in electronics and damage valuable items, such as artwork, documents, and collectibles.

By removing excess moisture from the air, dehumidifiers prevent the absorption of moisture by these items, thus preserving their condition and longevity.

Dry Clothes and Carpets
