The 5 Best Essential Oil Diffusers For Large Rooms
It’s not uncommon to find your diffuser isn’t living up to your expectations. This is likely because you’ve found yourself with a model that's too small, therefore unable to provide aromatherapy to every corner of your room. Investing in one of the best essential oil diffusers for large rooms can easily fix this problem, however — just move that small one into the bathroom, where it'll work even better (and be a pleasant surprise for guests!)
There are a few different types of essential oil diffusers that can deliver instant aromatherapy to achy joints, frazzled minds, and broken hearts. But if you’re diffuser is too small, you may not be utilizing their full potential. Nebulizing diffusers work without the help of heat or water to atomize essential oils by breaking them up into smaller particles that can be evenly distributed in the air. Ultrasonic diffusers are wildly popular because they act as both a diffuser and humidifier, which means they do require water, but they’re also multi-functional which is especially beneficial during cold or allergy season. Evaporative diffusers, on the other hand, use a fan to circulate the aromas of the essential oils, and while they’re definitely the noisiest of the bunch, they don’t require water and are often more affordable.
Whatever you choose, you’ll need to make sure it comes with a tank that's large enough to fill up that big room of yours. Check out five great options below.
1. The Best Overall: A Large Capacity Diffuser That Doubles As A Night Light And Humidifier
With its 1,000-milliliter tank and a convenient remote control so you can adjust the settings without having to get up, this essential oil diffuser is perfect for large rooms. It features three timer settings (3, 6, or 9 hours) and lights up in seven different LED colors. In fact, the nightlight function can be used independently from the diffuser. As even more of a bonus, it also functions as a humidifier: Put it on low-mist mode, and it can run for up to 15 to 20 hours (while the high-mist mode runs up to 10 to 15 hours). Last but not least, it has an auto shut-off function for added safety, so it'll turn off by itself once the tank is empty.
What fans are saying: "OMG! A friend convinced me that using a diffuser will help battle my allergies and produce better sleep at night. I was skeptical until the first time I plugged in this device. Sold instantly. It runs all night on one tank of water, and even my pets have noticed the difference."
2. An Ultrasonic Diffuser And Humidifier With A 20-Hour Run Time
For a heavy duty dose of aromatherapy, consider this ultrasonic humidifier and diffuser duo, which was specifically created for large rooms. It is designed to humidify the air in rooms up to 325 square feet and provides aromatherapy scent coverage up to 450 square feet. With a large capacity 1,500-milliliter tank, and a knob with 270 degree rotation to control the humidity level, you can let this gadget run, hassle-free, for up to 20 hours. Plus, since it doesn’t use heat to disperse the aromas of essential oils, it will better retain their "integrity and holistic properties". Other highlights include its whisper-quiet function and seven different LED light options, ranging from bright to dim.
What fans are saying: "I’ve had this diffuser now for about a week. It’s fantastic. I have a large living room and needed something to not only scent the space but also have a large enough tank that I’m not refilling it several times a day. It scents my living room, dining room, and kitchen and runs from 5am to 9pm on high before needing refilled. It’s easy to clean and super quiet. I’m really impressed."
3. A Sleek Nebulizing Diffuser That Covers Up To 800 Square Feet
Since this nebulizing diffuser doesn’t use heat or require water, essential oils will retain more of their natural benefits, which means faster and more potent relief. With an ultra-sleek and modern-looking design, it can cover up to a whopping 800 square feet of space, making it perfect for open concept homes or lofts. It has soft, LED mood lighting (which is optional), an adjustable mist level, and automatic shut-off after 2 hours, which can be a pro or a con, depending on the way you plan on using it. Perhaps the most interesting aspect is the device itself, which is made of oak wood and handmade ceramic.
What fans are saying: "I love the calming effect of the soft and soothing light. The fact that it comes with 2 glass reservoirs makes switching essential oil blends quick and easy. I use one reservoir to greet family and friends and one for my own personal needs. I also might add the diffuser is very quiet and easy to clean. I love the simplicity of it, the ceramic top and wood base complement one another nicely."
4. A Bluetooth-Enabled Diffuser That Doubles As A Speaker
This diffuser and humidifier duo does it all: In addition to dispersing your favorite aromas, it also works as a speaker (it's Bluetooth-enabled) and night light (it lights up in seven different colors). It does have the smallest tank of the products on this list — only 200 milliliters — but it can still run for up to 7 hours. If you're looking for something that'll diffuse an entire yoga studio or floor of a house, you'll probably want to go with one of the heavier-duty options above. But if you're looking for an efficient, multi-tasking device that'll spruce up your large bedroom, this one won't let you down.
What fans are saying: "It’s super simple to use and immediately had the desired effect! It adds a very soothing element to the atmosphere, last night I listened to my sleep meditation and used a few drops of my soothing night time blend and this is the first time in a long time I was able to fall asleep in peace."
5. Best On A Budget: A Quiet, Multi-Purpose Diffuser With Tons Of Positive Reviews
This budget-friendly diffuser is another wonderful option that offers multiple functions, albeit at a cheaper price tag. Not only does it effectively disperse essential oils into the air, but it also acts as a nightlight and humidifier. It offers seven LED light options that can be turned off, set to cycle gradually, or fixed to the color of your choosing. With ultrasonic technology that ensures the quietest of functions, this is a beautiful little diffuser packs a powerful punch: While its 500-milliliter tank might not diffuse an entire floor of a house, it'll certainly do the job in spacious bedrooms or living rooms.
What fans are saying: "This is such a great diffuser! Nice looking, practical and easy to use. Really like the different colors, and the mist is just right. The time settings are perfect and has a smooth beep when the time setting is over. I wish it was cordless to use it from the night stand to dinning table to kitchen counter, the cord gets in the way. Other than that, it's a great product. I practically use it daily."
