Products Tested by The Spruce
How We Tested
We bought a top-rated whole-home humidifier and our reviewers tested it for 96 hours. We asked our testers to consider the most important features when using this humidifier, from its effectiveness to its special features. We’ve outlined the key takeaways here so that you, too, know what to look for when shopping.
What to Look for in a Whole-Home Humidifier
Effectiveness Above all, you want a humidifier that can help keep your home’s humidity balanced at the level you want. Some models are so effective that they may prevent your wood floors from drying out and help control static electricity. To decide which humidifier will work best for you, consider the climate in which you live, the size of your home, and your budget—and look for a unit that fits your criteria.
Features While many humidifiers simply balance the humidity in your house, others come with extra features. For example, certain units double as diffusers for essential oils. Also, if your humidifier will be on display in a busy area of your home, you may want to pick a design-forward unit that doesn’t clash with your decor.
Ease of use Some humidifiers are more of a hassle to set up and use than others. Certain models plug into the wall, while others may require professional installation. Also, consider the size of a humidifier’s water tank and how often you’ll have to refill it.

What We Don't Like
Replacing filters can get pricey
This unit earned top marks from our tester for its performance in big homes: “It’s effective at humidifying a large space,” he said. “It’s also easy to clean and doesn't need to be refilled often.” Its main negative, however, was its design: “It’s bulky and clinical-looking,” he noted. He also pointed out the fact that since it doesn’t have a reusable filter, buying new filters can get costly. Overall, though, he said that “if you don't care about looks, this unit gets the job done.”
