Essential oil diffusers provide aromatherapy benefits including relaxation, better sleep, and pain relief. They work by releasing cool mist which helps eliminate dust from the air, increase humidity, and add pleasant aromas to the environment. Many essential oil diffusers also come with colored lights that you can turn on and off to create the mood lightening of your choice.

“When purchasing an essential oil diffuser, there are a few aspects to consider that include the mechanism of the diffuser, the size of the area in which you are aiming to use the diffuser, the reservoir size/intended time span of use, as well as other factors like the aesthetic appearance, noise production, size, and weight,” says Jessie Lucking, health coach at Parsley Health.

To select the best essential oil diffusers for our list, we researched the category, gathered insights from Lucking, and considered factors like dimensions, capacity, material, and power source to inform our product recommendations. For those who want to turn their bedroom or bathroom into a calming, spa-like experience, these diffusers check all the boxes.

Overall, the best essential oil diffuser is the Pure Daily Care Ultimate Aromatherapy Diffuser & Essential Oil Set. It can hold 300 milliliters of water at a time and comes with 10 different essential oils to get you started on your aromatherapy journey. There are several options of diffusers to fit your needs, whether you need a pet-safe option, portable diffuser or an option for larger rooms, such as the Jack & Rose Diffusers for Essential Oils Large Room.

When choosing the best essential oil diffuser for your home, size is an important factor to consider. First, look at the dimensions to ensure it will fit well in your space. If you plan on using your essential oil diffuser in a small room or bringing it with you on vacation, consider a compact and portable option. However, if you want the mist and scent to cover a larger space, look for a larger essential oil diffuser.

It’s also important to consider how much water can fit in the diffuser before needing to be replaced. Higher-capacity diffusers are typically best for large rooms because the scent can reach a larger area and they can run longer before requiring more water.

It’s important to clean your essential oil diffuser frequently to ensure it works properly and prevent any mold or mildew from building up. For best results, rinse it out each time you change essential oils and deep clean it about once a month. The diffusers that double as humidifiers may have additional cleaning requirements, so make sure you follow the manufacturer’s instructions.

Before cleaning your diffuser, make sure it’s unplugged and the power source is turned off. Start by emptying out the reservoir to remove any standing water or leftover essential oils. Then add water and vinegar and run the diffuser for 10–15 minutes before wiping it dry with a cloth.

The best essential oil diffusers come with a variety of useful settings including LED lights in several color options, auto shutoff functions for safe use, and continuous or intermittent mist modes. These features are standard on most of the essential oil diffusers on our list, but if you’re looking for more sophisticated features like timers or WiFi compatibility, make sure to choose an essential oil diffuser that has all of the bells and whistles you want.

“The mechanism of the diffuser is particularly important as there are multiple different styles of diffuser including nebulizing, ultrasonic, heat or evaporative,” Lucking says.

Most of the essential oil diffusers on our list are ultrasonic. “An ultrasonic diffuser releases essential oil into the air as a result of vibrations caused by a plate which emits ultrasonic waves, creating particles of oils which disperse into the air,” Lucking says. “This type of diffuser uses a water tank and also creates a fine mist. The oil remains intact because heat is not used and it can also provide a humidifier effect.”

Nebulizers are a more expensive type of diffuser that produce stronger scents by turning essential oils directly into mist without requiring water or heat.

When it comes to specific essential oils, “each individual oil or blend will elicit different responses and experiences so it is important to select oils that are aligned with your desired outcome,” Lucking says. “You may use lavender for relaxation, anxiety relief and sleep support and conversely, peppermint and citrus for an uplifting and invigorating effect. It is important to select the aromatherapy that is conducive to your goals.”

“First and foremost, for safety, you want to be certain you are purchasing high quality essential oils that are free of synthetic ingredients,” Lucking says. “It can be helpful to determine the plant sourcing, production, and quality/control testing that the company uses to ensure the potency, efficacy, and quality of the product.”

Some essential oil diffusers are not safe to use around pets because certain essential oils can be harmful to pets if ingested. It’s important to keep your diffuser at a safe distance from your pets and only use approved scents. When in doubt, ask your veterinarian what essential oils are safe to use around pets.

The best essential oil diffusers can provide many physical and emotional benefits including relaxation, better sleep, and improved moods. Physical benefits can include healthy skin, pain relief, and clearer breathing.

“An essential oil diffuser allows the user to engage in aromatherapy which is the practice of using aromatic materials, including essential oils, for therapeutic benefit,” Lucking says. “When inhaled, the molecules in essential oils travel from the olfactory nerves directly to the central nervous system, particularly impacting the amygdala, known as the emotional center of the brain. There is clinical evidence to support the use of diffusers and oils for anxiety reduction, mood elevation, and relief for nausea and headaches; however, other conditions are being explored that require further research.” According to Lucking, some essential oils may also provide a purifying effect to the air which can help decrease the impact of environmental contaminants.
