The Best Essential Oil Diffuser
The GuruNanda Tower XL Essential Oil Diffuser is hands down the largest diffuser on our list and one of the best diffusers for essential oils. This product not only provides diffusing of essential oils for up to 16 hours at a time, and it also humidifies the air because of how much water it can hold. Many diffusers do not possess a large enough water tank to humidify the air, but this tower certainly does. Unlike other humidifiers, it does not monitor the moisture levels in the air though. This tower stands out in a room and is very large, making it hard to hide but an excellent choice for large, open spaces and open plan living and dining areas.
This diffuser comes with three modes and features an auto-shutoff feature. While there are no timed features, I’ve found you can simply fill the diffuser up as much as you need and let it run instead of all the way full for varying run times. One of our favorite features is the remote, which allows you to control this diffuser from your comfy chair across the room. Read in-depth review here.

Why You Should Trust Us
I’ve been utilizing essential oils in skincare products and for aromatherapy purposes for nearly a decade. I have been through training and classes on their uses and benefits in various methods, including topical use, diffusing, and as an ingredient in skincare and haircare products. This background of knowledge is complemented by personal exploration and experimentation in my daily life. There are eucalyptus and lime essential oils in my diffuser right now. What is in yours?
Who This Is For
This list is for aromatherapy newbies and veterans alike. Whether you want to dive right in with a diffuser and oil set, upgrade your current diffuser, or adding a diffuser to a new space—there is something for everyone here. We dive into the nitty gritties of choosing a diffuser in our features and FAQ sections so that you can make educated decisions regardless of your experience with essential oil diffusers.
How We Picked
When selecting essential oil diffusers, we ensured that each diffuser had excellent reviews and high quality. The second item on the agenda was to ensure that the list as a whole met the needs of a wide variety of readers. This list contains diffusers that range in capacity from 100ml to 500ml, a huge variety in designs and features. We wanted to ensure that each diffuser served a particular need or person and that our list holds something for every home, office, or space that might house an essential oil diffuser.
How We Tested
When testing our selection of diffusers, we made sure to test these in multiple spaces. Testing occurred in rooms as small as 100 square feet and as large as 600 square feet to understand how they functioned in various spaces. We ran tests on timers and continuous modes and multiple scents to make sure we captured as much of the realm of usage as possible.
Features To Look For In Essential Oil Diffusers
Design – When selecting a diffuser, you will want something you find aesthetically pleasing, unless you plan to tuck it away in the corner of a room you never look at, but there is no fun in that. Diffusers come in various shapes, sizes, and color schemes. Some diffusers will even have unique designs on them. Consider the theme of the room you plan to put the diffuser in and what would look best with your existing décor.
Size – The ideal size of your diffuser will correlate to the size of your space. Some products will advertise a particular square footage that they cover. If you are placing your diffuser in a large, open plan living area, you may want to go with something on the larger size. On the other hand, if you are placing the diffuser in a bathroom, small bedroom, or tiny studio apartment,
Color – Much like choosing a design, you will want to select a diffuser in a color you like or matches your current home décor. Many diffusers have changing colors and LED lights, so you aren't stuck with a singular color, while others offer a wood grain fitting for modern and boho homes. It might help to envision where you expect your diffuser to sit in your home to understand what color may work best for you.
Features – Some diffusers offer simplicity in plug and play fashion, while others come loaded with features such as colored lighting and timers or intensity setting. When considering your essential oil diffuser, you might consider your current décor when thinking about lighting features.
If you want the diffuser's light to be the star of the show, you might opt for a more translucent diffuser that allows for more lighting patterns to dance around your home. Alternatively, if you would rather have your diffuser nestle quietly into your décor, a woodgrain or printed design may be more up your alley.
If you want to customize your essential oil diffuser's mist flow, look for one that allows you to change the flow intensity and run time.
Water Capacity – Similar to size considerations, water capacity often determines the square footage a diffuser can cover. Less water capacity means a shorter run time and smaller footprint, while a greater water capacity means the diffuser can cover more ground. The diffusers on our list vary greatly in water capacity, so there is something for every room and every home.
Operating Time – Many essential oil diffusers will have several operating time settings or, when turned on, will run until the water is gone. Many models provide both options. Health experts suggest running your diffuser for 30 minutes to 60 minutes at a time. Looking for diffusers with set timers is a worthy investment. Alternatively, one of my favorite perks of larger diffusers is that I can let them run unattended until the water is gone, and I get to come home to a calming, wonderfully-scented environment.
Material – Most diffusers are plastic. The kind of plastic tends to vary from diffuser to diffuser; using plastic allows for varied designs, durability, and water resistance. While you may find diffusers constructed of other materials, all diffusers on our list are mainly plastic.
Durability – Your diffuser will likely remain in a singular place, so durability isn't a grave concern. However, if you live in a busy home of multiple people, kids, or pets, it may be worth it to verify your diffuser can survive a few tumbles caused by unruly dogs, cats, or children. Most diffusers are constructed of plastic and hold up to a few dings and regular use. I have used quite a few diffusers in a massive range of sizes and quality in my life and have yet to destroy or break one, leading this author to believe these devices to be pretty sturdy.
Essential Oil Diffuser FAQ
Q: What is an essential oil diffuser?
A: An essential oil diffuser breaks down essential oils into small particles, using water as a carrier, and disperses them into the air for a pleasant smelling room and better ambiance. The diffuser should disperse the particles at an even rate that does not overwhelm the space nor its inhabitants.
Q: What are the benefits of essential oil diffusers?
A: Diffusing essential oils has many benefits. We all love being in a nice smelling room, right? This reason is why hotels and other hospitality services focus on smells so much. The fragrance creates an atmosphere that can make or break an experience.
While essential oil diffusers come with an upfront cost, they often cost less overall than burning through a $15 Yankee Candle every week.
Additionally, when diffused, essential oils can aid in stress relief and self-care and improve your sleep. Studies are also showing that essential oil diffuser benefits extend to decongestion, much like products such as Vick's Vapor Rub.
Lastly, early studies are also showing that peppermint oil, when diffused, can increase energy levels and curb your appetite.
Q: What is the difference between an oil diffuser and a humidifier?
A: An essential oil diffuser is for use with essential oils for aromatherapy. Humidifiers add moisture to the air via a warm mist. While these two devices may seem similar, they have different purposes. Humidifiers often have much larger water tanks than diffusers, which are needed to regulate the moisture in the air and do not provide aromatherapy.
Q: How do you use an essential oil diffuser?
A: For most essential oil diffusers, use is straightforward. Generally, you will add water and a few drops of essential oil, replace the lid, and hit the power button. Before using your new essential oil diffuser, be sure to check the instruction manual as every model varies.
Q: How long should you run an essential oil diffuser?
A: Health experts recommend diffusing for 30 to 60 minutes at a time, then leaving your diffuser off for 30 to 60 minutes before diffusing again. Some diffusers have settings to run for an allotted amount of time, while others run until they are out of water.
Q: Are diffusers bad for your lungs?
A: Diffusers are not harmful to your lungs unless you have a sensitivity to a particular oil. Essential oil diffusers have plenty of benefits depending on which oils you are diffusing. You should use caution with certain essential oils like cinnamon or clove and take precautions around pregnant women, pets, and infants.
Q: Are diffusers bad for pets?
A: Some animals are more sensitive to essential oils than others. Cats are more sensitive than dogs and birds, while fish are generally unbothered by essential oils. If your animal is particularly sensitive, consult with your veterinarian before diffusing oils around your pets. In general, the following essential oils should not be diffused around pets: cinnamon, citrus, pine, peppermint, thyme, and ylang-ylang. However, always check with your vet as each breed and each species can have additional sensitivities.
Q: What essential oils should not be diffused?
A: In general, most essential oils are okay to use when diffused. However, some oils are potentially irritating to those who are more sensitive, including cinnamon, clove, peppermint, thyme, and lemongrass. If you are pregnant, consult with your doctor before using essential oils.
