While the plants in my bedroom thrive in the direct sunlight next to my window, they also sit close to a heating vent that sucks the moisture from my room during the colder months. City dwellers like me, or anyone whose home lacks humidity, may benefit from using a humidifier (alongside regular watering) to help hydrate indoor plants.

Our top-tested humidifiers are a great way to ensure your plants stay hydrated throughout the day without much effort. "There are no humidifiers out there specifically designed for plants so using any humidifier for your plants will work to help boost the relative amount of humidity in a space," said Paris Lalicata, a plant expert for The Sill.

In recent years, our experts in the Good Housekeeping Institute Home Improvement & Outdoor Lab have tested more than 20 humidifiers. To determine the best humidifiers for plants, I collaborated with our team of analysts to comb through testing feedback on performance, design and ease-of-use features.
