"Diffusers have the ability to interact with the brain and many systems of the body to impact mood and overall health," says aromatherapist Barbara Close, explaining that different fragrances can do everything from boost your mood to help clear up your sinuses.

Our best overall pick is the Vitruvi Stone Diffuser, a ceramic-encased device with a BPA-free reservoir, ultrasonic technology, LED illumination, and a 550-square-foot coverage area.

What We Like
  • Large coverage area

  • Long power cord

  • Several colors available

What We Don't Like
  • Pricey

Chic and buzzworthy, the Vitruvi Stone Diffuser is tough to beat. Available in several minimalist-aesthetic, neutral hues, the matte exterior is made of real ceramic, and inside, there's a BPA-free plastic reservoir. Thanks to modern ultrasonic technology, it diffuses oil without heating up, gracing spaces as large as 550 square feet with a pleasant dose of aromatherapy.

Just fill it up with water, add 10 to 15 drops of your preferred essential oil, then turn it on and let it do its thing. We like that this diffuser has an extra-long 6-foot power cord, two misting modes (interval or continuous), and an automatic shutoff feature. There's even an optional LED light for added ambiance. Although this option is a bit more expensive than others on our list, we think the superior design and technology combined with a chic aesthetic make this pick worth the spend.

What to Look for in an Essential Oil Diffuser

Type

As aforementioned, there are two types of essential oil diffusers: ultrasonic and nebulizing. Ultrasonic diffusers use water to release the oil while nebulizing diffusers use air. Since the oil is less diluted in nebulizing diffusers, you can reap more aromatherapy benefits than from an ultrasonic diffuser. Nebulizing diffusers also have a smaller footprint and usually have glass reservoirs, which is great if you don't want your essential oils to be in plastic. However, there are some drawbacks. They are noisier than their ultrasonic counterparts and since they do not dilute the oil, they use it up quicker, meaning they're not as budget-friendly. Aside from being quiet and budget-friendly, ultrasonic diffusers can run for longer periods and can even double as a humidifier. Whichever one you pick will largely depend on your personal preferences and needs.

Square Feet

Make sure that the essential oil diffuser you're thinking of purchasing can cover the size of the room you plan to place it in. Most diffusers only cover up to around 500 square feet. If your room is larger than this, it may be best to invest in more than one diffuser.

Run Time

Depending on your needs, you may want to check the run time of your essential oil diffuser. Some diffusers can run up to 10-hours, making them great to use while sleeping. If you don't plan to use it while you snooze, the run time isn't as important.

FAQ
  • Can you use tap water in your essential oil diffuser?

    If you're unsure, check with the manufacturer on what they recommend using for the specific diffuser. Usually using tap water over distilled water is a personal preference. Some believe the minerals in tap water allow the oil to disperse more effectively into the air. Plus, distilled water would add to the cost of your diffuser if it isn't something you already purchase for your home. However, some also fear that you could be breathing in impurities by using tap water. Tap water can also cause mineral buildup, which could damage your diffuser's reservoir over time.

  • Is it bad to put too much oil in an essential oil diffuser?

    In short, yes. As a general rule, you should only be putting three to five drops for every 100 milliliters of water. Putting too much oil in your diffuser can be dangerous, so it's important to stay within the recommended range.

  • Can you sleep with a diffuser on?

    Yes, it is safe to sleep with an essential oil diffuser on, but you do not want your diffuser to run continuously through the night as this could risk overexposure to the oils. Fortunately, diffusers come equipped with safety features like timers and auto-shutoff to help prevent any overexposure. If your diffuser does not have a timer, try running it for a few minutes before you go to bed and shutting it off.

  • How often should you change the water in your essential oil diffuser?

    Most manufacturers recommend changing your water and cleaning your essential oil diffuser after each use. You can dump any excess water and wipe the reservoir dry with a microfiber cloth.
