11 Best Essential Oil Diffusers of 2024

Vitruvi's stylish yet efficient diffuser scored the highest marks across every category of our tests. Emitting a solid stream without being too overpowering scent-wise, its slim build means it won't take up too much shelf room — though testers reported it still gives a good output. The thin light strip on the bottom is optional for those who prefer to keep their rooms dark at night. Many testers compared its sleek, simple ceramic design to a piece of art. "The fresh hues are perfect to add some color to your space while you indulge in your everyday rituals, whether that’s a long bath, cooking dinner or reading your favorite book," says Vitruvi founder Sara Panton. If there's one downfall, it's the price.

Escape your space with this affordable model that uses seven different mood lights fit for an added bit of ambience. Its sleek, faux-wood design complements décor well. Like many other models, it automatically shuts off when it runs out of water, and you can choose between continuous and interval mist settings, although some reviewers say the output isn't as powerful as others. Though we haven't tested it in the Lab, Amazon reviewers call out its functionality in small rooms like bathrooms or offices.

At just $16 and a 4.5 out 5-star Amazon rating, the Innogear essential oil diffuser is the whole package. Let any of its four faux wood designs reside in clean, minimalistic areas or opt for the basic white that shows off its built-in LED lights. The top of the Innogear features a lock close at the base, which makes it easier to fill and transport from room to room without spilling. The only note shoppers made was that it gave off a humming sound, which is common in diffusers but notable enough on this one, and it doesn't have an auto shut-off capability.

With more than 47,000 ratings, the Asakuki Smart Wi-Fi model is one of Amazon's best-selling diffusers. It impressed just as much during our tests, still emitting a solid mist stream for hours after the others ran out of water. Its large water tank and compatibility with Amazon Echo's Alexa make it ideal for anyone who wants to infuse a large area (like a living room) while controlling the device from their phone or via voice, though some reviewers reported trouble with voice command. Set up sleep timers, adjust the lighting and control the mist mode remotely!

From sound machines to foot spas, Homedics impresses our experts and GH staffers alike with its relaxing gadgets. The two-in-one humidifier and essential oil diffuser may even help to hydrate skin by using a cool humidifying setting that shoppers say disperses into a fine, even mist. Fret not for constant refills: The humidifier holds up to 0.5-gallons of water, which tallies up to 25 hours of runtime, per the brand. Much like a traditional diffuser, it comes with seven colored night lights, though some reviewers complain they're a bit too bright. Simply add your essential oil of choice to the included tray pad.

Small and sleek, the Stadler Form's Jasmine diffuser became a quick favorite among our testers who enjoyed its elegant look without the high markup. The matte finish easily blends in with other popular tech gadgets (one tester said it resembles an Amazon Echo). We love its easy setup and found it lasted longer than some of the diffusers with similar water capacities, although some reviewers noted the interior gets stained by oils. Plus, our surveys show it's not a hassle to clean.

Designed with sleek ribbed lines, the Jack & Rose corded electric diffuser is one of the more stylish diffusers we've found. It can switch between seven colored lights, and its lightweight build makes it easy to move to different parts of the room. Some found it filled a bedroom well while others said it wasn't strong enough to diffuse a large room like a living room. Others noted they found it difficult to remove the lid for refills. However, should issues arise, many shoppers praised their "professional and outstanding" customer service.

This extra tall humidifier and diffuser comes with a removable attachment wand for extra height and versatile table-to-floor use. "That extra piece is a game-changer," said one GH tester. "I have it on my nightstand with the extension so it can be taller than my lamp without wetting it." In addition to its cool setting, the 360-degree nozzle sends out bursts of warm mist — great for humidifying — while the essential oil tray simultaneously infuses the room with scents.

An essential oil diffuser doesn't get more discreet than this, but don't let looks deceive: This plug-in wall diffuser is a smart device, which explains the steeper-than-average price. Download the Pura app to control the scent intensity, create custom schedules and switch between the two oils fitted inside. Per the brand, it infuses a space up to 1,000 square feet with its scents. The starter device comes with refreshing aqua and yuzu citron, but the brand frequently collaborates with fragrance brands like Nest and Capri Blue, too.

In addition to a 400ml ultrasonic essence diffuser, this set also comes with 10 essential oils including lavender, eucalyptus, tea tree, orange, peppermint, lemongrass, jasmine, nutmeg, clove and spearmint oils. Though some reviewers say it requires frequent cleaning, it's an Amazon best-seller, popular for its cheaper price tag, seven light settings and four-timer feature. One Amazon reviewer raved about the latter: "I usually start the six-hour timer before bed to get the oils started in the bedroom and then it turns off in the middle of the night."

The USB compatibility makes it easy to charge wherever you are, although the outlet plug is sold separately.
