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.

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!

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!

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.

Features | Sealed HEPA filtration, deep clean cycle, solid-state formaldehyde sensor, control with remote, app, and voice services
Size | Up to 800 sq. feet
Price | $900+

The Dyson Purifier Humidify+Cool models are designed for a heightened climate of pollution and hygiene awareness. These machines uses fully sealed HEPA filtration to securely capture 99.97% of particles as small as 0.3 microns(!) like allergens, bacteria, pollen, and mold spores. Their newest model is even able to sense and destroy formaldehyde! This is our team’s go-to for serious humidifying. It’s sleek and gorgeous too and great in any room.

Price | $90

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.

Features | No filters needed, remote-controlled, automatic shut off, removable water tank
Size | Up to 650 sq. feet
Price | $200

Objecto’s W7 Ultrasonic Humidifier is one of the only filter-free options out there—which means there are no single-use accessories involved. At two feet tall, it’s got incredible coverage for up to 650 square feet. And while it’s an investment, this hybrid humidifier comes with a remote control, aroma options, automatic shut off, and almost 22 hours of nonstop run time. The woodgrain finish is especially chic!

Best For | Zero electricity costs
Features | No power needed, goes over floor vents, silent operation, child- & pet-friendly

Price | $25–$55

For a more affordable humidifier, the Rumidifier doesn’t require any electricity! You simply place it over a floor or wall vent, and the circular filters get right to work bringing moisture to the room. Because there aren’t any charges or moving parts to worry about, it’s a great humidifier to keep in a child’s room, pet area, or plant nursery. Rumidifiers are available online or via Home Depot, Costco, and other major retailers.

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! Filter-free and without any additional hidden costs, we love how the minimalist design lets it fit easily into any space.
