Can I Use My Dehumidifier and Humidifier at the Same Time?

Share Post:

As the winter months descend upon Chicagoland/St. Louis, the familiar chill in the air signifies the onset of colder temperatures and a decrease in humidity. With the drop in outdoor temperatures, indoor heating systems often become a necessity, inadvertently causing the air to become dry. In such conditions, maintaining optimal indoor humidity levels becomes crucial for both comfort and health. This is where the symbiotic relationship between dehumidifiers and humidifiers comes into play, offering a tandem solution to balance indoor moisture during the winter months.

Mold Solutions understands the significance of harmonizing humidity levels within homes, especially in a region like Chicagoland/St. Louis, where winter’s cold air holds less moisture. Let’s delve into the benefits of utilizing both dehumidifiers and humidifiers simultaneously to achieve an ideal indoor environment.

Maintaining Comfort and Health

During winter, heating systems extract moisture from the air, leading to dry indoor conditions. This dryness can cause discomfort, leading to issues like dry skin, irritated sinuses, and respiratory problems. By using a humidifier, moisture levels can be increased, providing relief from these discomforts.

Conversely, excessive moisture can lead to dampness, fostering an environment conducive to mold growth and mildew. This is where the dehumidifier plays a vital role by reducing excess moisture, preventing mold proliferation, and maintaining a healthy environment.

Balancing Humidity Levels

The recommended indoor humidity level during winter falls between 30% to 50%. Mold Solutions recommends that the dehumidifier be utilized when the humidity is between 50% to 55%. A dehumidifier aids in reducing excessive moisture, ensuring the level stays within this range, preventing the growth of mold and mildew while enhancing air quality.

Simultaneously, a humidifier works to add moisture to the air, countering the effects of indoor heating systems and maintaining the desired humidity range. This equilibrium of moisture levels creates an environment that is both comfortable and conducive to good health.

Just remember when we’re going to have a cold snap (below zero-mid teens) you might need to lower your humidifiers. If you see condensation on the insides of your windows, it’s set too high.

Protecting Your Home and Belongings

Dry air can also affect your home’s structural integrity and the well-being of your possessions. Wooden furniture, musical instruments, and even electronics can suffer from the effects of dry air, leading to cracking, warping, or static electricity buildup. Using a humidifier helps in preserving these items by maintaining adequate moisture levels.

On the other hand, excess moisture can cause problems such as peeling paint, musty odors, and structural damage. Dehumidifiers play a vital role in preventing these issues by controlling humidity and protecting your home from potential damage.

Energy Efficiency and Cost Savings

Optimal humidity levels can contribute to energy efficiency. With balanced moisture, the air feels warmer at lower temperatures, allowing for a slight decrease in heating, and potentially reducing energy bills. By maintaining a balanced humidity level using both dehumidifiers and humidifiers, you can optimize your home’s energy efficiency during the colder months.


In Chicagoland/St. Louis’s winter, achieving the ideal indoor environment involves a delicate balance of moisture. By employing both dehumidifiers and humidifiers, households can ensure comfort, health, and the preservation of their homes and belongings.

Mold Solutions advocates for the combined use of these devices to regulate indoor humidity levels, making homes in Chicagoland/St. Louis more comfortable and healthier during the winter season. Strike the perfect balance and take control of your indoor environment by using dehumidifiers and humidifiers in harmony.
