Humidifiers and dehumidifiers both modify the level of humidity in your home. Which one you need depends on the climate you live in as well as individual preferences. Here are the differences between humidifiers and dehumidifiers so you can decide which would be best in your home.


A humidifier is useful in regions where the air is too dry. Low humidity levels can cause headaches, nosebleeds, dry skin, and allergy problems. It can also cause wood furniture to dry out and crack.

There are two types of humidifiers. A cool-mist humidifier emits cool vapor into the air. A warm mist humidifier boils water and emits warm steam. Both types of humidifiers need to be kept clean so mold and mildew don’t grow in them.


A dehumidifier removes moisture from the air. They are great in hot and humid climates. High humidity levels cause problems for people with allergies and encourage mold, mildew, and dust mites to grow and multiply.

The most common type of dehumidifier is one that is refrigerative. This type of dehumidifier has a fan that draws in moist air and sends it over a refrigerated coil. Moisture is drawn out of the air and drier air is released back into the home.

Ideal Humidity Level

Whether you’re using a humidifier or dehumidifier, the ideal humidity level is between 30% and 50%. You can buy an inexpensive hygrometer at home improvement stores to measure the humidity level in your home. If the humidity level is below 30%, get a humidifier. If it’s above 50%, you need a dehumidifier.
