Humidifiers vs. Dehumidifiers: Comparison & Benefits

Humidifiers and dehumidifiers are both devices that can improve the overall air quality of your space! These devices improve air quality by either increasing or decreasing the moisture in the air, also known as humidity. Humidity refers to the concentration of water vapor present in the air. Humidity is relatively expressed as a percentage and controlling indoor humidity is very important for your health and your home. According to research, the recommended ideal humidity level for your home should be between 40%-60%.

What is a Humidifier?

The dry air in your space can cause many issues for your health and home. Dry air is common during winter months when we turn on the heat. A humidifier is a device that adds moisture back into the air in the form of mist to improve the overall indoor air quality of your home.

What is a Dehumidifier?

While a humidifier is used to increase the moisture in the air, a dehumidifier does the exact opposite! A dehumidifier decreases the humidity in the air in damp spaces in order to prevent any musty odors, mold, and mildew by extracting water from the air. Too much or excess humidity can have a negative impact on your health by aggravating allergies and asthma symptoms. Dehumidifiers can also help manage flooding or water leakage!
