5 Best Non-Toxic Air Humidifiers (2025 Review)
The Good Trade editors endorse products we’ve personally researched, tested, and genuinely love. Learn more about our methodology and business model here.
Our team has researched and tested dozens of sustainable humidifiers for safe, high-quality, and affordable options — these are our top seven picks.
Deal with sinus congestion, dry skin, or colds every winter? Happens to the best of us! That’s why we like to prep for the season with a reliable humidifier. Humidifiers add just enough moisture to the air to keep us feeling warm and hydrated.
What are the benefits of using a humidifier?
Numerous benefits come from using a humidifier in your home. The added moisture in the air from humidifiers can help relieve dryness of the skin, nose, and throat caused by the weather or heaters. If you’re prone to allergies or have asthma, using a humidifier can also help you find relief by keeping your airways moist, especially during the night when you sleep or if you’re feeling ill. Humidifiers even benefit our furniture and instruments, helping prevent them from drying out over time. Be sure not to overuse your humidifier as too much moisture can have adverse impacts on your home. Optimal moisture levels for your space will typically range from 30-50%.
While many big-box humidifiers are popular, they’re not always the most sustainable, often requiring plastic filters or large amounts of electricity. Instead, here are the best humidifiers for an eco-friendly home using energy-efficient technology, paper filters (or none!), and automatic controls. Many are even a combination air purifier and humidifier or humidifier and diffuser — a win for the winter!
Our criteria:
- DURABILITY | These humidifiers are made with high-quality materials and backed by warranties, so you can use them for years. Some even have nontoxic materials for an even cleaner home!
- DESIGN AND QUALITY | With beautiful, sleek, natural, and modern designs made with high-quality materials, you’ll find a humidifier on our list that suits your style.
- COVERAGE AREA | We’ve included humidifiers that cover both small and large spaces for optimal effectiveness.

Our Editor’s Review | “After two weeks of testing the Canopy humidifier, I’m excited to recommend this device for people who are looking to up the ante on their well-being routine, as well as folks who need a little bit more hydration in their nighttime skincare routine. The price point for the humidifier is in the middle range (including replacement filters), but with regular use, this purchase can last several years. This humidifier is a great addition for folks who have skin health goals that include more moisture. ” – Stephanie Valente, Contributing Editor [Read the full review.]
