Looking for the best humidifier for your whole house? Our humidifier experts researched over 20 models, and determined the 10 best models to include in this test. We then purchased and tested these whole house humidifiers in our lab for side-by-side comparisons. Our lab's scientists measured humidity levels during whole-house tests, and observed how they affected indoor air quality. They assessed airflow and power consumption, measured noise, and noted how each humidifier performed while cleaning multiple rooms. Through our in-depth reviews and comparative study, we've determined the 10 best humidifiers for your whole house.

Humidity can have a huge effect on your indoor air quality. If your humidity is low, you're at risk of getting sick. Excessive humidity can cause mold and mildew growth. Choosing the best humidifier for your home is an important decision. We thoroughly researched entire-house humidifiers, and reviewed selected models in this test. If you're unsure which product to choose, consult our guide for the best humidifier.
