Essential oils are everywhere these days.
You can buy a wide variety of scents meant to provide comfort and relaxation, relieve stress, or to stimulate and excite.
Essential oils can be applied directly to your skin using a carrier oil for spreading, or diffused through the air using an essential oil diffuser.
Diffusers are little machines that take drops of an essential oil, mix the oil with water, and distribute into the air so you’re able to breathe the oil in and enjoy the oil ambiently.
With so many essential oil diffusers on the market, we decided to gather all the information you might need in order to make a good decision on which diffuser is best for you, and to review some of the top options available.
What is an Essential Oil Diffuser?
Essential oil diffusers are used in aromatherapy to diffuse essential oil into the air. You insert drops of the oil, turn the diffuser on, and are able to smell and inhale it in the air. As you breathe in the scent of the oil, you’ll receive the relaxing benefits that the oil contains.
Instead of going out to a relaxing location, you can turn your home into a place for aromatherapy with an essential oil diffuser. Not all diffusers are created equal though.
What are the Differences Between Humidifiers and Diffusers?
It’s not uncommon for people to confuse diffusers and humidifiers. They can look fairly similar and are both used to treat the air you breath. They’re different though in what they’re designed to do and the tasks they perform.
Humidifiers are used when the air is dry to increase the moisture content in the air. They can be stand alone appliances or integrated into a larger heating system to humidify an entire home.
Humidifiers are popular in drier climates and in moderate climates during the winter when furnaces and heating systems dry out the air.
While a diffuser emits water vapor into the air like a humidifier, diffusers are designed to take and mix essential oils with that water, while humidifiers can be damaged if used with essential oils.
Generally it’s not recommended to use a diffuser and humidifier at the same time, as too much humidity in the air will dampen the effects of the essential oil from the diffuser.

10. TomCare Square Cool-Mist Aromatherapy Essential Oil Diffuser
The TomCare diffuser is a striking square design with wood accents and the lights cover the entire unit and we haven’t seen many diffusers in this shape. The UPC number 713924816489 is a best seller on Amazon.com®.
The diffuser is a 5-in-1 unit in that it not only emits a fragrant mist, but the water produces negative ions that boosts moods and is calming. It’s like the feeling you get when it’s raining—you feel soothed and want to take a nap. Plus, it’s a nightlight that delights the kids, and a small humidifier with its vapor of moisture. And, it’s a small air purifier cleaning and disinfecting the air with oils that help with that.
The diffuser holds 700 mL (24 ounces) of water to run 20+ hours in the low-mist mode and about 10 hours using the high-mist mode, then shuts off automatically with no beep sound. Set the unit to run 1-, 3-, or 6-hours or set it to run continuously. Just add 5 to 10 drops of 100% pure essential oils (not included) on top of the water and turn on. It will cover about 800-square feet of space.

The plastic is made of polypropylene (PP) and acrylonitrile butadiene styrene (ABS). It is BPA-free.
From my experience, 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.
Put one in your baby’s nursery for congestion using eucalyptus or peppermint essential oils. Citrus can be used with no problem.
The shape harmonizes well with any design scheme in your home. It is also lovely in reception or waiting areas for doctors, chiropractors, bank lobbies, spas, massage and physical therapist studios, nail, or hair salons, and anywhere you want a heavenly fragrance with therapeutic benefits from the oil you choose. Yoga and Pilates studios love these too.
The dimensions are 6.5- x 6.3- x 5.7-inches.
Plug the 6-foot UL® listed cord into a USA, Mexico, or Canada 110/120-Volt, 50/60 Hz (Hertz) outlet. Those in other countries will need to buy a 220/240-Volt adapter. The diffuser does not use batteries. It cannot be used in vehicles. The adapter is packed inside the diffuser.
Gift-wrapping is available for loved ones, family, and friends. You will receive the diffuser, alternating current (A/C) power adapter inside the diffuser base, and User’s Manual. It comes with a 1-year Warranty and is made in China.

It indeed uses 400 mL (13.5-ounces) of water to add essential oils. Without water, you would not get a mist and that would make this a nebulizer diffuser using no water using only pure straight oils in its bottle.
So, add your 8 to 10 drops of 100% pure essential oils (not included) on top of the water, set the functions you want, and enjoy the 7 different colors of LED lights either on or off. The colors are red, orange, yellow, green, blue, indigo, and violet—just like the rainbow colors.

It will shut off automatically when the water is gone. Did I say water? Yes, it is not “waterless.” Amazon shows the description to be “waterless” and that is not true! It indeed uses 160 mL (5.4-ounces) of water to add essential oils into. Without water, you would not get a mist and that would make this a nebulizer diffuser consuming no water using only pure straight essential oils in its own supplied bottle.
The 7 intriguing LED light colors will entrance your kids and you too. It is mesmerizing and there are no beep sounds with this unit ever.

The Anjou, model number AJ-AD001, is stunning, is not “waterless” using 300 mL (10.14 ounces) of water to cover about 450-square feet. For a heavenly fragrance and therapeutic benefits, add 2-8 drops of 100% pure essential oils (not included). It does produce negative ions with the water the same as rain does. Negative ions lift your mood and so do some essential oil essences.

4. Tenswall Ultrasonic Cool-Mist Essential Oil Aromatherapy Diffuser
The faux wood grain Tenswall Ultrasonic Essential Oil Aromatherapy Diffuser is a lovely soft ebony black plastic. The plastic is made of polypropylene (PP) and acrylonitrile butadiene styrene (ABS). It is not BPA-free however.
The color harmonizes well with any design scheme in your home. It is also lovely in reception or waiting areas for doctors, chiropractors, bank lobbies, spas, massage and physical therapist studios, nail, or hair salons, and anywhere you want a heavenly fragrance with therapeutic from the oil you choose. Yoga and Pilates studios love these too.
Some think it looks like a tulip or flower vase, but in person, it looks like a fancy gourd and I love the shape. It is quite large and holds 400 mL (13.5-ounces) of water for adding your 100% pure essential oils (not included). About 8 drops is nice, but if you want a more intense fragrance, add more. The oil floats on the water, since oil and water do not mix, so the intensity is at the beginning and you will probably want to add more drops after a few hours of running.
From my experience, 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. That’s scale buildup is hard to clean and mold makes spores for more mold growth wherever it’s damp or wet.
Put one in your baby’s nursery for congestion using eucalyptus or peppermint essential oils. Citrus can be used with no problem.
The diffuser is a 5-in-1 unit in that it not only emits a fragrant mist, but the water produces negative ions that boosts moods and is calming. It’s like the feeling you get when it’s raining—you feel soothed and want to take a nap. Plus, it’s a nightlight that delights the kids, and a small humidifier with its vapor of moisture. And, it’s a small air purifier cleaning and disinfecting the air with oils that help with that.
It is an ultrasonic diffuser so it naturally holds water. A “waterless” diffuser is a nebulizer and this is not that type. Therefore, do not be confused by the title description on Amazon.
The LED (light emitting diodes) cascade through the 7 colors of the rainbow: red, orange, yellow, green, blue, indigo, and violet. Let it cycle through all colors, set it to one favorite color, or turn the lights off completely. The lights can be set to dim or bright for whatever you like best.
The timer can be set for 1-, 3-, or 6-hours to run 60-, 120-, 180-minutes or continually on up to 10 hours. It will turn off automatically when it’s low on water.

You should get about 500-square feet of coverage space. The lid does not screw on or off or snap into place—it simply sits on top and is not a problem. The 3 rubberized feet will hold it steady to not slide off furniture.
Plug the 6-foot UL® listed cord into a USA, Mexico, or Canada 110/120-Volt, 50/60 Hz (Hertz) outlet. The output power is 650 mA (milliamps).

Around the circle ring where the base meets the top is where the LED 7 assorted color lights will illuminate. You could put fake flowers such as silk or plastic in the top little holes; however, do not put real flowers in because the stems would produce chemicals you don’t want in the unit, your lungs, or the air. You wouldn’t want real flowers in the unit when its running anyway.

Pour that off and add plain water to the Max line to rinse letting it run another 15 minutes. Use cotton swabs and let it air dry.

Do You Wonder if You are Buying Fake Essential Oils?
Mother nature has provided us with many amazing healing plants. The oils from these plants can work wonders for you if used properly. As with any other type of product, there is some pretty low quality and fake essential oils in the marketplace. Many are packaged very nicely and can fool you, unless you know what to look for. We hope you get a bottle of liquid in an amber bottle that has been distilled from the flowers, leaves, and roots of an aromatic plant. Some websites offer “extended” essential oils having mixed them with fillers such as seed and nut oils that are cheap. Some use fake synthetic chemical fragrances such as those spray cans for room fragrance and candles all made with chemicals that mimic the scent of the plant. Even aroma therapists can be fooled. If the price is too good to be true, it probably is fake. Good essential oils are expensive, but well worth it.
We have evaluated the top 10 rated aromatherapy essential oil diffusers and features to help you with your buying decision. The many therapeutic benefits and pleasant aromas are presented for you to evaluate for your personal needs and enjoyment.

1. Air Purification—The diffusing units are not “machines.” A lawnmower is a machine. Therefore, when you read “machine” at other websites, you might get a visual impression of something large. These units are small, portable, and marvelous for breathing clean, purified air, for removing tobacco smoke and other disagreeable odors. The essential oils have anti-microbial and anti-bacterial components derived from Mother Nature’s wonderful plant kingdom to benefit health happy people.
2. Dust Removal—Diffusers are ionizers. Negative ions attract dust particles, allergens, and other substances. With a diffuser, you will have cleaner air. Diffusers can help those people who suffer from dust allergies, dust mites, asthma, and other allergic ailments. Negative ions are another of nature’s laboratory of wonderful things!
A Side Trip About Negative Ions. Negative ions are in the air and might not be love, but are close to it. Colorless, odorless, and tasteless, they are invisible molecules we inhale abundantly. Think about the outdoors—beaches, waterfalls, mountains, the woods, the forests—these are rich negative ion areas and they are around us when it is raining. In the bloodstream, negative ions produce biochemical happenings that increase our levels of the mood enhancing brain chemical, serotonin that helps to remove stress, depression, and increase energy.
3. Help Uplift Mood and Eliminate Stress—Specific essential oils are known to lift a down mood up. These oils also relieve stress and mild depression. You will feel calmer and relaxed using essential oils with a lovely diffuser. Enjoy and feel secure knowing that the fragrant and purified air has been improved using oils.
4. Improve Immunity—When you purchase an oil diffuser, it means that you will be boosting your immune system by breathing in the plant’s natural and pure beneficial oils.
5. Whole Room Fragrance—Nothing is more appealing then when you laze around feeling enveloped by sweetly scented smells. An ultrasonic diffuser will do this for you, since the unit uses infinitesimal elements from the plant’s properties that wonderfully and elegantly distribute throughout the room. Within a few minutes, you will be experiencing your experience.
6. Humidifier—People exposed to pollen in the air are sometimes sensitive or allergic to their influences. Nasal allergies are miserable. The mucosa in the nose becomes inflamed and mucous is secreted. Humidification can help with that. The diffuser puts out moist air to alleviate the symptoms with its fine spray mist. It can raise the humidity up to 40% more than the current ambient level. You can use the diffuser with water alone to have more humidifying moist air effects.
7. Removes Foul Odors—The diffuser used with your favorite essential oil will remove last night’s fishy odor, smoky smells from tobacco products, and any other offensive or stale smells. Your area will smell fresh in no time.
8. Purity of Essential Oils—Because the essential oils are not heated, they maintain their chemical properties from the source from which they were created—nature’s finest plants. You receive the benefits of this from the ultra-fine mist that permeates your space.
9. No Waste—Most oil diffusers have an automatic shut off feature. This permits no waste of your essential oils in that you used them for their purpose and the unit has now shut down. If you do not want to use the full reservoir, shut the unit off and the oils will be there for the next time you turn it on. The oils do not just evaporate into thin air. They are either consumed or waiting to be consumed.
10. LED Lights—Most all diffusers today have light emitting diodes (LED) that have usually 7 colors of the rainbow. I like to remember them this way: Roy G Biv—red, orange, yellow, green, blue, indigo, violet and sometimes white. They can typically run on one color, cascade through all colors, and be turned off completely. Checkout nature’s rainbow—the colors are in this order!
Types of Essential Oil Diffusers
There are several types of diffusers available in the marketplace. Here, we have tried to categorize them to their specific functions. The commonly available types of aromatherapy diffusers are: Nebulizer, Ultrasonic, Evaporative, and Heat.
1. Nebulizer Diffusers
These diffusers are considered the most powerful. They are cold-oil diffusers that disperse pure essential oils by breaking them into tiny molecules. Later these airborne molecules are misted out to create a fragrant atmosphere. The Nebulizer aroma diffusers are ranked higher due to their therapeutic qualities. Since this type of unit does not require adding water, a heavy concentration of aromatic oil is diffused into the atmosphere.
These diffusers use 100% pure essential oils making them more health-friendly. They also have a built-in timer that keeps you informed. No light system is provided with the Nebulizer diffusers.
Nebulizer aroma diffusers are considerably noisy and that can be a turn off for many. It is more expensive and that can be considered a negative to some users. These diffusers scatter larger quantities of oil at one time, consequently they need refills more often, and that can prove costly for many buyers. To control the extra emittance of oil, Nebulizers are now provided with a built-in timer with settings.
2. Ultrasonic Diffusers
Similar to nebulizing diffusers, Ultrasonic diffusers also disperse oils by breaking them into smaller particles. The only difference is the addition of water. These diffusers use a mix of water and essential oils to create a cool mist. They are, however, not as powerful as the Ultrasonic diffusers due to the mild concentration of oil.
Ultrasonic diffusers double up as humidifiers in wintertime. This is a great advantage for this type of diffuser. They come with a music setting that cuts down on the noise they make. These aromatherapy diffusers are less expensive than Nebulizers are.
Since water is added with essential oils in the Ultrasonic diffusers, these are not as efficient in their healing power as Nebulizers. Sometimes, these wellness devices come with a light setting that cannot be turned off. You need to keep it clean and avoid using citrus essential oils in these diffusers.
3. Evaporative Diffusers
These basic aromatherapy diffusers scatter essential oils with a fan blowing method with an attached filter. Its evaporating functioning style has given it the name Evaporative Diffusers.
This type of aromatherapy diffuser works perfectly in diffusing fragrance in a smaller area. Another benefit of buying evaporative aromatherapy diffusers is their relatively low cost. These diffusers are easy to carry and come in pleasing designs.
Evaporative diffusers do not disperse the complete blend of essential oils at one time. They tend to portion out the oils. Lighter components are evaporated quicker than heavier components. This apportioning of the components (oils/water) cuts down on the overall therapeutic value of the essential oils. Another drawback of these diffusers is that they have shorter running times.
4. Heat Diffusers
This is also a basic oil diffuser, but instead of evaporating essential oils with the help of an air fan, it uses heat for diffusion. Heat diffusers also create a lovely fragrance inside a closed area.
These are considerably the least expensive of all the aroma oil diffusers readily available to purchase. Most heat diffusers are so small that you can keep them in your vanity kit or purse. They indeed effectively aromatize a specified area.
Since heated oil diffusers also function by evaporating essential oils, they also portion out the components of essential oils. It affects both the healing benefits for oil and the intensity of the fragrance. Some of these diffusers use high levels of heat to produce an extra strong aroma that can change the chemical bonding of the essential oils. Therefore, a diffuser that uses very low levels of heat is considered better.
All 4 Diffuser Types Reviewed and Compared
To know the most efficient category of aromatherapy diffusers, we compared all of the differences regarding the aspects of aroma diffusion, therapeutic value, longevity, and price.
Dispersal of Aroma
Nebulizing diffusers distribute the essential oil by breaking them into smaller molecules allowing it to diffuse fragrance in a shorter time in a larger area. Ultrasonic diffusers also diffuse oil similarly and they equally aromatize an area effectively while evaporative and heat diffusers work well in scattering the fragrance in a smaller area.
Since the Nebulizing diffuser is a cold aroma-dispersing device, it uses the purest form of essential oils. It ranks higher than all other aromatherapy diffusers with heating. The Ultrasonic diffuser is second best while heat and evaporative diffusers are not considered the best for aroma healing because essential oils work best when used cold.
Ultrasonic diffusers are the winner when it comes to running time. These diffusers use a blend of water and a few drops of essential oil. Their higher capacity helps them in diffusing aroma for hours without any breaks in time. Nebulizing diffusers disperse a greater amount of essential oil at one time and might need to be refilled more often. Similarly, evaporative and heat diffusers need to be refilled more quickly.
When it comes to price, heat diffusers are the clear winner, followed respectively by evaporative and ultrasonic diffusers. Nebulizing diffusers are the costliest of all.
So, Which One is Best?
After weighing all criteria of aromatherapy diffusers, ultrasonic diffusers are the best. Nebulizing diffusers are second to the Ultrasonic one but the biggest drawback is the cost. Low longevity, greater energy consumption, and the irritating sound made it a disadvantage.
Things to Keep in Mind when Choosing the Right Diffuser
You now have the information for purchasing a diffuser for getting the most from the therapeutic benefits from the essential oils in many fragrances. When you feel perplexed by the many options, do not buy just anything that will not be the best one for your needs. Delightful diffusers of greatest quality and features will last years and are easy to get for less than $100.
The following tips will capture your attention for the best features for a hassle-free shopping experience when you are carefully checking out oil diffusers.
1. Water Capacity—Water determines how long a diffuser will keep operating. When you want your diffuser to run for many hours at a time, you will need one that holds more water in its reservoir. The choice ultrasonic diffusers can hold 80 to 100 mL (2.7-3.38 ounces) of water.
2. Operating Time—Consider this feature for the length of time you want to run your diffuser. Some units operate for 3-4 hours and others run 6-10 hours. If you want to have your diffuser run all night when sleeping for its therapeutic benefits, you will want to select a diffuser that runs nonstop for longer hours.
3. Program and Timer Options—Practiced diffuser users can tell you the importance of these two functions. For best results with the essential oils, diffusers are super effective producing your desired results in small amounts. A micro-fine mist can be dispersed with a superior dispenser. It is not always necessary to have your diffuser run constantly, unless that is what you want. Maybe you want your diffuser to run for a certain length of time and then restart. If you want that, shop for a programmable diffuser with time cycle selections. This will control the amount of your treasured essential oils accomplishing the best possible benefits.
4. Variable Airflow Output—Controlling the air pressure allows the scattering of the essential oils where you can check the fragrance intensity. It is similar to how fast you want a fan to run.
5. Room Coverage—Read the specifications before buying a diffuser. This will tell you the area it will cover. Trendy diffusers cover 200-300-square feet and some cover up to 500-square feet. You might be disappointed if you purchase a diffuser not able to cover the area you want. Reading customer reviews will help you when they discuss their experiences.
6. Automatic Shutoff—Users prefer this option because it safeguards against the unit burning out. When you are preoccupied, you will have no worries. When the diffuser runs out of water, it will automatically shut off. This is a wonderful feature for when you are sleeping; the unit will shut off and be safe and sound in the morning.
7. LED Light Effects—Almost all quality diffusers have a built-in light. They are used as night-lights as well as for daytime enjoyment. You can choose the changing colors you like and the light can be turned off in most units. You might want to check out which diffusers have light dimming and brightening capabilities.
8. Noise Level—Some people do not mind the slight noise and others do. If you are one of those people who like quiet in your space, check the suppliers who carry Whisper Quiet Technology. With the whisper quiet diffusers, you will not hear the slight buzzing or water trickling sounds.
9. Warranty and Guarantees—Most manufacturers provide a 1-year warranty for their products. Some warranties can be for longer periods and most offer money back guarantees for up to 6 months if you are dissatisfied with their product.
10. Size and Shape—Today’s aromatherapy oil diffusers are gorgeous to look at and add a touch of flair to your home, office, spa, or salon décor. The designs, colors, and shapes are stylish and trendy for the discerning and sophisticated buyer. Some shapes are contemporary in design such as a candle shape, pyramidal shape, disc, and freeform in shape. Shop for just the right one for your special place, never being disappointed.
Size does matter and is dependent on portability if that is an important highlight for your lifestyle. If you want to carry the diffuser in your purse or satchel, a more compact style will work best for you.
Step-by-Step Guide for Choosing the Perfect Oil Diffuser
Answer the questions below to help you make a decision for purchasing a diffuser:
1. Where do You Want to Use Your Diffuser?
Where you plan to use your oil diffuser will help in your selection process. If you plan to use it in the bedroom for its LED light effect, consider a diffuser with a turn-off switch. Some people do not sleep well with a light on and some do not care for lights when relaxing or napping.
2. What is the Purpose for Using the Diffuser?
If you plan to use the diffuser for sleep or relaxing, it should have no noise effect and the LED light. To realize the therapeutic advantages the diffuser needs to be able to maintain the efficacy of the essential oils.
For a child’s room, the diffuser needs to have an automatic shutoff feature. If you or someone suffers from allergies, has irritated, or rough, flaky, dry skin, the diffuser will perform as a misting humidifier and air purifier.
Ask yourself why you desire to have an aromatherapy oil diffuser. Depending on your needs, the best selections are the Ultrasonic, a Nebulizer, or an Evaporative or Heat Diffuser. These diffusers function differently; therefore, it will be important for you to consider the way each one operates. If you want intense healing without the price being a concern, then the Nebulizer will be your best choice. The Ultrasonic diffuser is great for simply relaxing, air purification, and humidification, and are cost-effective.
3. Get Help from Reviews

You will find on the Internet the manufacturer’s claims, people’s experiences using diffusers, and find advice about the coverage area, ease of use, operation times, the LED light pros and cons, and how to clean the unit. You can also ask questions to the reviewers and they will come back with an answer.

Which one is the quietest that I can use as I sleep. I am a very light sleeper? And which one can I also use in my car at the same time? And which oils are the best but affordable? Thank you so much for your research, saves me hours!! I have been looking for years now So much to choose from drives me crazy!! lol
Melissa26 May 2017
First for your car: Try the very small Verelily NOVA that uses no water and you can also put it in your car! I love this one and it works nicely at my office desk too. See it here. It is whisper-quiet using no water. Who wants want spills in the car, right? You attach a bottle of oil that will not spill when screwed in when driving. It has a battery inside that stays charged when you keep it plugged in for use in the house or office. You can read about the brands in the contents above. Just click it and it will go to that brand.
Oils. I like blends/singles and my favorite is Ovvio Oils shown here.
My very favorite for day or night time sleeping is Slumber, Rest and Recovery blend that is heavenly, and I’m not kidding. I go to sleep instantly. The label shows you all the different plant ingredients 100% pure therapeutic grade in 15 mL amber glass bottles. It’s affordable.
Hope this helps you decide.

I have been searching and searching for what you refer to in your notes as a programmable diffuser with time cycle selections and have yet to find one! Is there one that you recommend? Thank you!
Melissa28 Sep 2017
Almost all diffusers have timers to program for different hours to run. Read about them on this page at the top. Example: See Zen Breeze above that shows this: “The unit holds 300 mL (10 ounces) of water and will run about 10 hours with one filling of water.”
Hope that helps.

I help manage a 700-seat performing arts theater. The venue would certainly benefit not just from improved air quality, but also by the ability to changes oils/scents based on type of event.
What large machines and/or systems would you recommend that could be installed to handle a room of our capacity?
Melissa28 Sep 2017
You would need to know your room’s square footage and calculate from there. I have no idea what a 700-foot room square footage would be. Then read the specs on diffusers above and go from there. Each diffuser gives the square-footage area.
Good luck with aromatizing your theater.

I am looking for an oil diffuser that lasts at least 8 hours and will put out the most vapor? Can you suggest one for me? I looked at so maybe I am ready to bang my head on the table. LOL
Melissa18 Nov 2017
Are you the same Mary who wrote below?
The Ultrasonic Cool Breeze Dinosaur Egg diffuser is a large unit that disperses large amounts of moisture and runs 8-hours plus. I own one and love it. It runs for me 12-14 hours.
Mary16 Nov 2017
I have been looking for an oil diffuser with the most output (covers the most square feet), runs the longest hours and also releases negative ions while diffusing. Do you know of one with all these features? I have read about so many I am dizzy.
Thank you so much.
Melissa18 Nov 2017
Are you the same Mary who wrote above?
The diffuser, I told Mary above, will do the trick for you. The Ultrasonic Cool Breeze Dinosaur Egg diffuser is a large unit that disperses large amounts of moisture and runs 8-hours plus.
All Ultrasonic diffusers that use water give off negative ions! First know that all water, such as the shower, a waterfall, and the rain, produce negative ions.
The 400 mL (6.8 ounces) water shuts off automatically when the water is gone. The unit will cover an area up to 500-square feet. Not many diffusers hold this much water to cover a room this large!
Hope this helps you. It’s a great diffuser.
