Are you trying to decide upon what is the best essential oil diffuser to buy? Do you want one for yourself or as a gift for someone you love? Look no farther—the best diffusers are reviewed here for you to make a sensible choice.
We also include different shapes, and capacities, with affordable price ranges and made a detailed Comparison Chart to help you choose the right unit.
How to Choose the Best Essential Oil Diffuser
If this is your first time buying a diffuser, it can be overwhelming. With my buying guide, the mystery is taken out of the process.
Follow my tips below to help you find the diffuser that works for me.
1. For my first essential oil diffuser I, the buyer, will purchase a small ultrasonic unit that uses water is less expensive, usually under $20.
2. For my second essential oil diffuser I, the buyer, will select from the two options listed below.
I, the buyer, will decide on an ultrasonic diffuser that has more features I would like such as a larger water reservoir and longer running timer, so it will mist all night, and those cost anywhere from $40 to under $80.
I, the buyer, will select a nebulizer essential oil diffuser that does not use water using only the 100% pure essential oils. The aroma is more stimulating, aromatic, and intoxicating.
I like the nebulizer functionality best even though it is more pricey, so I’m buying it.
3. If you choose an ultrasonic, remember to buy a unit that holds at least 300 mL (10-ounces) of water and can run at least from 2- up to 8-hours that can cover at least 300-square feet.
4. For either type, select diffusers having adjustable mist levels of low, medium, and high. This function tells the fan to go slow, medium, or fast.
5. Everyone loves the cascading colors of the LED lights. Almost all diffusers have these lights so select the one that comes with the unit if you want it for a nightlight too. If you don’t want the lights on when you sleep, you can turn the lights off.
6. Ultrasonic diffusers come with an automatic water shutoff when the water level is low and nebulizers will also shut off automatically when the pure oil level is low.
7. Along with the features I will want to consider how my diffuser will look. Do I want fun whimsical animal or train shapes for my kids, or do I want one that is shaped like rocks, pyramids, vases, candles, or are freeform in shape? These can be simple yet charming, sophisticated, glamorous, or complex.
Essential oil diffusers are trendy and add flair and provide aromatherapy for your home, businesses, lobby, boutique, or spa.
Now that I have taken the mystery out of buying an essential oil diffuser, you can go to the Comparison Chart for the best 10 ultrasonic units to select from shown below.

The base is faux wood grain and the LED 7 changing color lights will magically illuminate the top part of the unit. The base will hold 500 mL (17-ounces) of water with distilled or purified being best since city tap water is full of lime scale and minerals to clog it up.

8. URPOWER® Square Ultrasonic Cool-Mist Essential Oil Diffuser, 700 mL
This is a one-of-a-kind square diffuser with faux wood accents on the top corner and base. The mist comes out of the wood corner. The diffuser is a 5-in-1 unit in that it not only emits a fragrant mist, but the water mist produces negative ions that boost moods and is calming. It’s like the feeling you get when it’s raining—you feel soothed and want to take a nap.
It is also a nightlight that charms and enchants the kids, and a small humidifier with its vapor of moisture. As a small air purifier, it cleans and disinfects the air with oils that help with that.
Fill the diffuser with 700 mL (24 ounces) of purified or distilled water to run 20-plus hours in the low-mist mode and about 10-hours using the high-mist setting, then it shuts off automatically when the water is low with no beep sound.
City tap water is not the water to use because of minerals and lime scale that clog up diffusers and the tube inside to draw up water for the mist. I use filtered or distilled water at about 99¢ a gallon. Minerals in tap water create a white dust on furniture tops as well. It’s best to change the water each day to avoid mold and bacteria growth. The scale buildup is hard to clean, and mold makes spores for more mold growth wherever it’s damp or wet.
Run the unit continuously or set it to run 1-, 3-, or 6-hours. Just add 5 to 10 drops of 100% pure essential oils (not included) on top of the water and turn on to cover about 800-square feet of space. You and the kids will sleep all night long with the whisper-quiet fan so not to be disturbed.
Set the 7 LED lights to cascade through all of its colors, set to your favorite one color, or turn the lights off completely. You can also set them to dim or bright for how you like it best.
The plastic is made of PP (polypropylene) and ABS (acrylonitrile butadiene styrene). It is BPA (bisphenol A)-free for safe use with babies and children.
When your baby or youngster is congested, try using eucalyptus or peppermint essential oils to relieve congestion and dry mouth and lips. The oils will also reduce stagnant odors such as tobacco, pet smells, and old dinner smells. Citrus oils can also be used with no problems.
The unusual square shape will look great and smell good too harmonizing beautifully with any design pattern in your home. It is also lovely in reception or waiting areas for doctors, chiropractors, bank lobbies, spas, Yoga, Pilates, massage and physical therapist studios, nail, or hair salons, and anywhere you want a heavenly fragrance with therapeutic benefits from the oil you choose. Elders in nursing homes or assisted living would delight in one of these units in their room.
The dimensions are 6.50-inches tall x 6.30-inches wide x 5.70-inches deep.
Plug the 6-foot UL® listed cord into a 110/120-Volt, 50/60 Hz outlet. Outside the USA, Canada, or Mexico you will need to buy a 220/240-Volt adapter. It does not use batteries; it is electric only and cannot be used in vehicles.

It’s actually a 5-in-1 diffuser. All ultrasonic diffusers using water are a diffuser, a small humidifier, an ionizer, an air purifier, and a night light. If you need a large amount of humidity, buy a humidifier.
It’s an ionizer because water naturally produces negative ions that leave you feeling calm and peaceful. The rain, waterfalls, rivers, and many other natural water producing elements do that as well and it’s healthy.
Using 100% pure essential oils (not included) will refresh your home removing stale odors and doggy smells. The aromatherapy you gain from the oils will give you a wonderful heady aroma. It does not come with a USB cable and does not use batteries.

Features to Look for Choosing the Right Diffuser
When you are shopping for one or more diffusers, you might be new to it and not know what to look for. People using diffusers for a long time pretty much know what is best for them. Hopefully, these hints will give you some ideas when looking at diffusers in the marketplace.
Each brand of essential oil diffuser has different features. Some features are similar while others are different. Remember this is a discussion about diffuser features, not what each brand will do. If you want to use many citrus oils, be sure to find a diffuser that does that. Not all diffusers use citrus such as grapefruit, orange, and lemon.
Attractiveness and Appeal
The first thing most of us look at is how pretty and colorful a diffuser is. We check the shape and then we look for the features we like most. We might want something charming, sophisticated, simple, glamorous, complex, or whimsical. We might want animal or train shapes for our kids. Diffusers add flair to your home or business décor. They are trendy and some are contemporary with shapes such as candles, rocks, pyramids, vases, and some are freeform. Please read on.
Where to use Diffusers
Nearly everyone wants a diffuser everywhere today. We are passionate about our essential oil diffusers for aromatherapy and therapeutic benefits. They can be placed in your home in every room, in the children’s rooms, in the bathroom, kitchen, and basement. Many want diffusers at their office desk. Professional offices want them in their waiting area and some dentists have them in the patient’s area. Hotel lobbies keep them around and some are portable to take with you in your hotel room.
Do you want it to hold lots of water such as 500 mL (16 ounces) or 80 mL (2.7 ounces) or less or even more? Does it matter? Do you want to refill it several times a day or have it run all night? Water capacity is something you will want to consider. The greater the amount of water the unit uses the longer the mist will run. And, of course, less water means less misting time.
Most diffuser manufacturers tell you to use tap water at the sink. Well, if you want mineral build-up and lime scale, you will have more cleaning to do with your diffuser. A gallon of distilled water is only about $1 at most stores and is well worth the cost to use it only. Your diffuser will function better and longer if you use distilled, purified, or soft water. What will clog your diffuser are thick oils with resins. They can clog the openings where the mist comes out.
Plastic—Some manufacturers use plastic only for water tanks. Some use plastic for the entire body and tank of the diffuser. We now want no toxins in our plastics known as BPA-free (Bisphenol A). BPA is a synthetic compound and is toxic. Check for the BPA-free label or words when searching for diffusers. Polypropylene (PP) is a thermoplastic polymer used from everything from car parts to carpeting. The PP, PU (Polyurethane), and PUR (Polyurethane) are hard, tough, strong, thick, and durable plastics that are heat resistant. They are not ‘bad’ plastics. Using BPA-free plastics means that when you are using essential oils in your diffuser you will not have chemicals leaching into your oils.
Ceramics—are made from the dirt of the earth and are not harmful. We use ceramic (terra cotta) cookware, dinnerware, and many other ceramic products daily. Diffusers made from ceramic are not harmful, are beautiful, and earthy.
Glass—is made from the sand of the earth and the best glass comes from sand in Kokomo, Indiana. Founded in 1888, Kokomo is the place for American art glass. When you use diffusers made of glass, not only are they beautiful and artfully shaped for your home, they will not be toxic in any way.
Stainless-Steel—diffusers are high quality and the material is tough and sturdy. We use stainless-steel in our cookware and bakeware and it’s the perfect solution for wonderful things. Stainless-steel is made from the basic elements in the earth: iron ore, chromium, silicon, and nickel. No health problems will be found using stainless-steel.
Wood—many diffusers are made of another earthy material, wood. They too are great diffusers to have around and use for their beauty and functionality.
Diffuser Size, Weight, and Stability
Size matters. Will it fit on the dresser, the night stand, the fireplace mantel, the desk at the office, the seating area at the doctor’s office—and many more places people use their diffusers. Do you want round or thin? Square or bulky? Do you want a remote-control unit or can you live without it? Each brand will show you this information. If you want to take your diffuser with you in your satchel or purse, then a smaller more compact unit will be the best for you.
Diffusers come in different weights from small at about 6-ounces to 1.5-pounds without water. They provide rubber feet to offer stability eliminating slipping and falling over making a watery mess everywhere. Most have silicone feet or a rubberized bottom.
You can select diffusers to mist an area of 50- to 1000-square feet. From the size of a bathroom to the entire open living area, you will find a unit for your space. So for large or small rooms, select the diffusers having the range of coverage for your needs. It’s possible you will need more than one unit. They are affordable and last a long time with proper care.
It is convenient to have the diffuser run for a long time so that you can forget about it. But then maybe you don’t want it to run all day or night. If you want it to run only to remove dinner odors, then maybe, you only need a unit that runs for 3-hours and shuts off. Speaking of shutting off, some units shut off automatically and some do not.
Read further for discussing the shutting off features and functionality for diffusers. Some 100% essential oil diffusers can operate for 10-hours and more. Each brand has its specific timer settings. The more oils you use with the mist mode set on high, the shorter amount of time it will run and the more oil will be used.
Some diffusers use settings to include interval misting every 20- or 30-seconds, so the oil diffuser mists in surges. If you do not want to run the diffuser until the water tank is empty, you can choose to run a larger-capacity diffuser for 30-, 60-, or 180-minutes and it shuts off automatically after the timer stops.
This feature would let you vary the air pressure for scattering the essential oil mist. It is comparable to how fast you operate a fan. It is the speed setting of low, medium, or high on the diffuser.
Some of us like lights and some of us do not want lights. Most units have a light display that is magnificent cascading from one color to another—the entire rainbow—red, orange, yellow, green, blue, indigo, and violet (ROY G BIV helps me remember).
Lights are pretty, calming, and cool to look at. Lights do not offer any health benefits, unless you simply want to feel relaxed from them. Some lights rotate blending into one another to have double the lights.
Some diffusers let you run the essential oil mist with or without lights, and some stay on one color only. Lights can be used for night lights for the kids or yourself. Some brands provide lights that have dimming and brightening capabilities. Diffusers also are available with no lights except a tiny light at the on/off switch and some people like this.
Some diffusers are whisper-quiet and some are a bit noisier. Many sound similar to a trickling waterfall that can be soothing and calming, yet others find even that slight sound to be disturbing. Search brands to find the one suitable for your hearing preference that will not be earsplitting to you.
Most diffuser’s sound will allow for conversations, movie watching, and reading. Make sure it’s not so close to you to be disturbing. Many users sleep with them close to their head on nightstands at night.
Automatic Shut Off
You want to be safe when using a diffuser for the baby’s nursery and kid’s room. In fact, you want to sleep 8-hours without having to worry about the unit burning up. On the other hand, you might only want to use it a few hours and turn it off yourself. Both types are available.
Almost all diffusers today come with an automatic shut-off feature. When the unit runs out of water in the tank, it shuts down. This is a great feature for safety. When you are occupied with other things, you need have no concerns with this function.
There are units that run on electricity and others that run by battery only. Some brands are made for USA only voltage of 110/120-Volts, 50/60 Hz. Other brands accommodate buyers using them outside the USA in Europe or other countries that use 220/240-Volts.
Maintenance and Cleaning
Cleaning a diffuser is quick and easy. Try a little liquid dish detergent in warm water using a cotton swab for the nooks and crannies. Rinse with cool water and towel dry. Paper towels stick and leave pieces, so a cloth towel is best. If you have sticky oil gunk, use one-fourth cup of clear distilled vinegar alone and let the diffuser run 15-minutes.
Empty the vinegar and rinse with cool water. To remove the vinegar smell let it run a few times with distilled water. Or, you can use rubbing alcohol rather than vinegar.
Warranties and User’s Guides
Check for the length of the Warranty when you search for diffusers. Most manufacturers offer a 1-year Warranty and others guarantee their product for 6-months. Other diffuser sellers offer less time for their guarantees and warranties. Most will stand behind a diffuser with defects in workmanship or if you are dissatisfied. The diffuser box usually has instructions. If not, the website will have a download for the items.
Tips for Using Essential Oil Diffuser
- Always talk with your doctor before using diffusers with essential oils if you have any medical conditions, are pregnant, or nursing.
- Do not use around babies, pets, and the elderly.
- Always purchase essential oils from a reputable company who will refund your money or the oils if you are not completely satisfied.
- Do not mix essential oils unless you know what you are doing.
- Read the instruction manual that comes with your diffuser and use it and clean it the way the manufacturer suggests.
- Remember that USA 110/120-Volt adapters do not work in 220/240-Volt outlets in Europe or other countries. Some diffusers do use both voltages. Check to see if a step-down transformer will work outside the USA or the voltage will burn out the unit forever.
We have given you information about diffuser/humidifier combinations. Feel confident, choosing what you like, and read the reviews. The units are not that expensive, so try a few different types with different functions.
Once you are addicted to essential oils misting gently at you with an ultrasonic or nebulizer diffuser—the best ones—you will be on a journey trying all of the wonderful 100% pure essential oils online.
Do not buy oils in the grocery store, big box stores, or department stores. They are usually watered down and are not the pure good oils. Happy shopping and come back to our site often for new things!

I think I like the Nebulizer for my bedroom, but I am not sure, I need to use them and then decide, I had no idea that one just used oil
My favorite is the Pure Enrichment PureSpa XL Ultrasonic Cool-Mist Essential Oil Diffuser. I love that it is a 5 in 1 and that it has a really large tank.
