7 Best Non-Toxic Air Humidifiers (2024 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 skin, nose, and throat dryness 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 have benefits for our furniture and instruments, as they can help 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, 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:
- NONTOXIC MATERIALS | These humidifiers are made with safe and non-toxic materials that will contribute to a 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.
If you’d rather have two separate devices, check out these sustainable air purifiers. Better yet, consider these indoor plants, which naturally clean and add moisture to the air in your home!

Features | 12 diffuser options, cordless & rechargeable options, natural ceramic & BPA-free plastic covers, automatic shut off
Size | Up to 1,200 sq. feet

3. Brondell
Best For | Front and rear filtration
Features | Dual True HEPA air filtration, natural evaporative humidifier, four operating modes
intuitive touch control panel, air quality indicator, allergy setting
Size | Up to 1855 sq. feet
Price | $500
The Brondell Revive uses a dual HEPA filtration system that makes it move through twice the air in half the time as comparably sized machines. Its super-efficient evaporative humidification makes for a more consistent humidity level too, wicking water up through a specialized filter and passing air through evenly throughout your home without creating dense vapor pockets that could damage walls, furniture, or carpet. We love that this is both a humidifier and air purifier and that it can work as a white noise option while sleeping (level 5 is loud!). Plus, it has the option to turn the display lights off, making it a great humidifier for nurseries.
Brondell Review | “We’re very happy with our Brondell it was easy to assemble and doesn’t make a lot of noise. We love the fact that’s it’s a two in one humidifier and air purifier. Thinking about buying another to cover more areas in our home. Also it was shipped surprisingly pretty quick.” -Erin K. (See all reviews)

Vornado, a leading air circulation and humidifier company, has an energy-efficient humidifier we love. The eco-friendly EVDC3000 covers up to 750 square feet at once, using 90 percent less energy than a traditional Dyson or Vicks humidifier. We love that it has auto-humidity control, low water indicators, and comes with an impressive warranty, all for under $100.
Vornado Review | “We use this humidifier to keep our main level comfortable. It’s approximately 1300 Sq ft and this humidifier has helped immensely. It’s much quieter and more efficient than our previous humidifier. We noticed a significant change in the humidity once we started using this. We would highly recommend it!” – Anonymous (See all reviews)

Designed by a doctor, Carepod is a simple, award-winning design that comes in three sizes for your office or home use. Fed up with the complicated cleaning needs and pricey filtration subscriptions of so many humidifier models, Carepod is the first humidifier that can be sterilized, leaving it safe and 99.99% germ-free; simply boil the three parts in boiling water, and you’re done!
