Best Essential Oil Diffusers for Sleep and Relaxation

If you’ve spent any time on the internet in recent years, chances are you’ve heard someone extol the virtues of essential oils. Lavender for sleep, peppermint for energy, and a whole host of others to relieve stress and anxiety. While the science on these plant extracts is far from conclusive, there is overwhelming anecdotal evidence that using a diffuser to dispense these oils into the air can help folks get a good night’s sleep. Without getting too into the weeds about the benefits of sleep, it’s clear that whether you’re a world-class athlete, a weekend warrior, or just working a 9 to 5, we can all benefit from better sleep.

There are hundreds of diffusers on the market. Most have a similar core functionality; namely, they spread the essential oil into a space via a mist, providing a pleasant fragrance. Many of these items also double as humidifiers, adding moisture to your space, which can help if you suffer from chapped lips or dry skin, live in a dry climate, or run an air-conditioning unit. With so many diffusers on the market, how can you tell which design suits your needs best?

Best Essential Oil Diffusers

Editor’s Choice

URPOWER Wood Grain Ultrasonic Aromatherapy Oil Diffuser

Pros: 

  • With a capacity of 150ml, this diffuser is designed to fill a 215 sq. ft. room with aromatherapy.
  • While this is equipped with a 7-colored LED light that can alternate between bright and dim, the light only emanates from the spout at the top and around the button, creating a more subtle look. 
  • This device can provide 3-4 hours of continuous misting or over 6 hours when set in intermittent mode. 

Con:

  • A potential drawback is that this device is a bit more expensive than some of the other small-capacity diffusers. The difference here is the design, which may be worth the extra cash for some folks.

Another diffuser that features a wood grain outside, URPOWER’s 150ml diffuser has a unique tear-drop shape. With less lighting than the other items on this list, this diffuser may be a bit more nuanced than some of the others.

Contender

Innogear Diffuser

Pros:

  • At $15, a very affordable diffuser and cool mister. 
  • Features an auto shut off function so that the device will not overheat when the water runs out. 
  • Measuring at just 5.5” tall, this is a compact unit that could easily be traveled during a road trip.
  • Features a whisper-quiet functionality, so you can set it up while you sleep and not worry about being woken up. 

Con:

A potential drawback of this model is that like most others on this list, the “On” light continues to glow even when the LED light is turned off.

Another iPhone-sized diffuser, Innogear’s model features an intermittent and continuous mist option. With a 7-colored LED light, this diffuser could also serve as a night light in a kid’s room.

Best Design

VicTsing Essential Oil Diffuser

Pros:

  • With a capacity for 300ml of water, the VicTsing is designed to provide mist for up to 10 hours. 
  • In addition to the light that wraps around the unit, the LED escapes from the top as well, giving off a sort of volcanic look. The 7 light colors come in a bright or dim option, giving you more design options. 
  • If LED lights keep you up at night, you can turn the lights off and just use the device as a diffuser or humidifier. 
  • Possible to set it to run for 1, 3, or 6 hours in addition to letting it run continuously. 

Con: 

  • At $29.99, this is the most costly of any of the diffusers on our list.

The VicTsing Diffuser features a unique design, almost resembling a genie lamp or an urn. With a woodgrain outside that incorporates a wrap-around LED light, this device can be used as a humidifier or a diffuser.

Best For A Bigger Space

Pros:

  • Equipped with two mist modes, this Aromatherapy Diffuser can alternate between a high and low setting, letting you have some control over how thick the mist appears. 
  • Comes with four timer settings, allowing you to determine how long the unit will run for. 
  • Designed to run for 10 hours with an automatic shut off function. 
  • With a woodgrain base and 7 color LED light, this device can double as a night light.

URPOWER’s 500ml offering has a similar functionality as its 100ml cousin, but fills more space. Built to serve as an essential oil diffuser for up to 430 sq. ft. of space, this model will work well for a master bedroom or living room.

Best Small Room Diffuser

URPOWER 100ml Essential Oil Diffuser

Pros:

  • With programmable on/off settings and an automatic shut off, this item is designed to provide mist for about 6 hours.
  • In addition to spreading your choice of essential oil into the room, it serves as a cool mist humidifier, helping with dry sinuses or chapped lips. 
  • The URPOWER has options for intermittent or continuous misting, a very quiet operating volume, and works with tap water.
  • The entire device can glow in 7 different colors, giving it functionality as a night light or, dare I say, a modern day lava lamp. 

Con:

  • While it’s possible to turn off the main LED light, there is a small green or red glow from the “Mist” button that does not go away while the device is in use, which may be bothersome for light-sensitive sleepers.

At $15, URPOWER’s 100ml diffuser is a great value and addition to a small bedroom, hotel, or even a cubicle (though you should probably check with your officemates first.) About the size of an iPhone, this little machine sports a 7 color LED light.

Methodology

As essential oils continue to become a bigger and bigger wellness trend, more and more companies are getting into the diffuser business. Though most diffusers have the same purpose, it’s important to take into account a few key features before deciding on one over the other. 

Space

If you’re buying a diffuser for a particular room in your house or apartment, you should have an idea of how big a space you’re intending to fill. A small, low capacity diffuser is not going to make much of an impact in a cavernous space. A diffuser can make for a great addition to a yoga studio or fitness room; try to get one sized accordingly.

Timers

Depending on how you intend to use your diffuser, having the ability to preset when it turns off may be important. Some of these devices are equipped with timers, automatically turning off after an hour or two. 

Lighting

Most diffusers today now offer some type of LED lighting implement. If you’re buying this for a child’s room, a diffuser with a bright light may double perfectly as a night light. But if you’re the type of sleeper who needs blackout curtains, you may want to find a less loud version

Design

Similar to lighting, this is really about personal taste. Some of the more expensive models feature woodgrain exteriors, which may end up serving as a lovely piece of accent furniture.

Sleepopolis Buying Tips

  • You’ll notice none of these diffusers come with any essential oils. That’s a different purchase. When shopping for essential oils, it is super important to make sure you’re getting the real stuff. Look at the ingredient labels – if you see the plant’s botanical name, go for it. But if you see something like “the oils from cinnamon” – you may want to stay away.
  • For the diffuser itself, the most important thing to know is the size of the room you’re trying to fill. Humidifiers and diffusers can be incredible sleep aids – but they work a lot better when they fill the space effectively.

Though the science behind essential oils is inconclusive, many folks find a lot of comfort in diffusers and humidifiers. If these scents help you to relax and sleep well, a diffuser is well worth the investment. Of course, if you develop a rash or any other type of allergic reaction, stop using the device and consult a doctor.
