    This uniquely designed oil diffuser features a wood grain exterior to give it a more natural vibe. To use, just unscrew the cap and add water along with the essential oil of your choice. It will run for up to 10 hours of continuous output but also has an automatic power shutoff when it runs out of water. It has adopted ultrasonic technology, which makes it extremely quiet while it’s running. There’s also an LED light with seven color options—available in a steady or changing color mode. And you can set it on a timer to run for one hour, three hours, six hours, or continuously.

    The majority of customers have been happy with this product. Many have said it works well and is super quiet. One person said they love that it has rubber feet which makes it more stable on the table and that it’s very easy to use. Some have had issues with it breaking or not diffusing as much steam over time but most customers would recommend it to others.

    InnoGear Aromatherapy Essential Oil Diffuser Portable Ultrasonic Diffusers with Color LED Lights Changing and Waterless Auto Shut-off Function for Home Office Bedroom Room, 100 mL
    Courtesy of
    Very Good

    A top-seller in its category, this oil diffuser features Whisper-Quiet Ultrasonic Operation which not only fills the space with a nice fragrances but also adds a light mist to keep the air from becoming too dry, preventing dry skin, stuffy air, and germs. The system shuts off automatically when the water runs out, and it’s portable so you can take it to the office, hotel, or even just move it from room to room in your home. Kids will love this too because it has seven changing mood lights (including green, dark blue, red, yellow, pink, light blue, and white.) It’ll work for three hours in continuous mode or six hours in intermittent mode.

    Customers who have purchased this product have been mostly happy with it. One said that they spent tons of money in the past buying candles but after purchasing this, those days are over, adding that maintaining the diffuser with oils is so much cheaper in the long run. Another said it was so quiet you hardly know it’s on. Some have said the LED lights are a little bright, adding that it’s a great night light but if you prefer to sleep in the dark, perhaps this isn’t a good diffuser for the bedroom.

    Best Lighted: URPOWER 300ml Aroma Essential Oil Diffuser

    URPOWER 300ml Aroma Essential Oil Diffuser Ultrasonic Air Humidifier with AUTO Shut off and 6-7 HOURS Continuous Diffusing - 7 Color Changing LED Lights and 4 Timer Settings for Home SPA Baby Room
    Courtesy of
    Very Good

    Looking for a quality light-up oil diffuser? This one from Urpower is a top-seller in its category. Featuring seven different colors you can choose from including white, red, yellow, and blue, it also gives the option to cycle through the colors in a kaleidoscope like rotation. Or, you can choose a color based on the mood you’re trying to convey or to match the scent you’re using (i.e., yellow for citrus, red for peppermint, etc.) Other features include a cool mist humidifier, whisper-quiet operation, and auto shut-off when the water runs out. It can work for up to six hours at a time.

    The majority of customers who have purchased this product were happy with it. Some have said they enjoy using it for the lights, but you can also turn them off and just use it as a diffuser if you want. The only issue is that there is a continuous power light that stays on, which is really bright for some when they’re trying to go to sleep. So if you’re going to be using it in a dark room, you might want to consider covering that light.

    Best Budget: URPOWER Aromatherapy Essential Oil Diffuser

    URPOWER 200ml Aromatherapy Essential Oil Diffuser Humidifier with 7 Color LED Lights and Waterless Auto Shut-off- Wood Grain
    Courtesy of

    This stylish three-in-one product acts as an aromatherapy diffuser, humidifier, and night light. It will run up to six hours with a low mist, and when the water runs out (there’s a 200ml capacity), it’ll turn off automatically for your safety. The LED light can be turned on, and you have the choice of using one of seven soothing colors including yellow, green, blue, and pink. And when you’re not feeling the aromatherapy, you can use the unit as a general humidifier to help provide moisture for dry cough, sinus irritation, and dry skin.

    The majority of those who have this in their home love it overall. One said it’s low maintenance for a lovely scent. Another pointed out that it’s quiet and they liked that it gives off the aroma with a mist, not just by heating the oil. One thing to watch out for: the top doesn’t actually latch on — it just rests on the base. So be careful about tilting it while it’s filled with water.

Others have praised how easy it is to use, but some noted that they deducted points for the machine not coming with instructions. In terms of other negative reviews, some found that it broke quickly, but many have said it’s a good machine for the budget price.

    A sleek design is what makes this oil diffuser stand out from the rest. Featuring a soothing light that can be set to your preferred brightness, it can also be set to breathing mode which cycles the light on and off to rhythmically to help you regulate your breathing, which is fun to use while you’re meditating. The device can operate for about eight to 10 hours at a time and features an automatic shutoff that stops operation when the water runs out.

    Most of those who purchased this seem to be happy with its performance. Besides it being a beautiful unit as one reviewer said, it’s also sturdy, quiet, and delivers the scent quickly into the room when in use. Some have had issues with it malfunctioning over time, but the majority would recommend it to others.

    Best Non-Electric: Ivenf Ceramic Tea Light Aromatherapy Essential Oil Burner

    Ivenf Ceramic Tea Light Holder, Aromatherapy Essential Oil Burner, Great Decoration for Living Room, Balcony, Patio, Porch and Garden, Vase Shape
    Courtesy of

    If you'd prefer to have an oil diffuser that doesn't plug in or require batteries, consider opting for an oil burner instead. This ceramic version from Ivenf doesn't actually burn the oil, but it relies on the heat of the flame from a tea light candle to warm the oil and disperse the scent.

    Not only will you get a pleasing scent, but you'll also get the added ambience of a flickering flame. Of course, the drawback with this option is that it requires more attention than an electric version. Plus, you can't use it while you sleep or rely on an automatic shutoff. But for those times when you prefer a tea light to a scented candle, this one is a winner.

    The necklace comes with six pads of different colors so you can coordinate and make sure you don't mix oils. Each pad is washable so you can keep changing out and switching up your oils. The pendant comes on a 24-inch stainless steel chain.

    Reviewers love the locket's quality and efficiency and say the scents they use release subtly throughout the day to help soothe headaches and more.

How We Tested

We bought four top-rated oil diffusers that our reviewers tested for 118 hours. We asked our testers to consider the most important features when using these diffusers, from their design to their capacity. We’ve outlined the key takeaways here so that you, too, know what to look for when shopping.

What to Look for in an Oil Diffuser

Type There are two main types of oil diffusers: ultrasonic and nebulizing. Both versions create a fine mist, but they work a bit differently. Ultrasonic models — the cheaper option — create vibrations that break the essential oils down and distribute the individual molecules into the air. Nebulizing models distribute more potent, undiluted essential oils into the air using pressurized air.

Capacity and time Ultrasonic models require a mixture of water and essential oils, which allows them to run for longer — approximately 30 to 60 minutes at a time. Since nebulizing models use only essential oil, they should be run for shorter periods (about 10 minutes at a time).

Cleaning Both types of models benefit from regular cleaning, but ultrasonic essential oil diffusers are more difficult to clean since they use both water and essential oils. Water makes the machine more susceptible to mold, and tap water can leave calcium deposits inside the machine.

“I have bad sinuses that dry out, especially in the winter when the heat is on, and this diffuser has helped relieve some of my usual dry sinus issues,” raved one of our testers. One of our reviewers, who used the diffuser in her office, said the aroma was particularly pleasant and carried well, prompting others to stop by and comment on the good smell. Our testers also liked that it can be set to run for a specific time period. In terms of negatives, our reviewers wished for a cordless option and also mentioned the lid doesn’t lock so it’s easy to knock over the diffuser and spill water.

This oil diffuser won over our testers immediately with its design. “The wood this diffuser is made from is smooth to the touch and looks nice anywhere,” one reviewer said. She added, “It’s not too extravagant and not too plain.” The machine was also effective and quiet. “I didn’t hear the motor running at all, which is ideal,” noted one tester. Our reviewers’ only criticism was the fact that the diffuser could only be powered via an electrical outlet. “I’d love a battery or charged option,” one reviewer stated.

Our testers loved this URPOWER diffuser because it offers multiple settings and sells at an affordable price (usually below $20). "The custom timing settings, sturdy construction, easy-to-use features, and its ability to scent a large space make this a great choice for everyday aromatherapy needs," one reviewer said. The downsides of this diffuser are its short warranty and its inability to switch between continuous and intermittent misting.

Calling this diffuser “perfect for a nightstand or living room table,” our testers liked its small size, visually appealing design, and overall effectiveness. “I have trouble falling asleep most nights, but having this on really helped me,” reported one of our reviewers. Our testers also liked the nightlight function and how easy it was to set up. The only drawback mentioned was that the water basin’s size limits the runtime to six hours, but our testers didn’t feel that was a dealbreaker. “This product is definitely worth buying — it's attractive, well designed, and works perfectly,” one of our reviewers gushed.
