Product Description

Meet the Whisper, our premium diffuser with the most positive reviews by customers! A resuable/disposable plastic cup holds your oils in water so that they never touch the state-of-the-art ultrasonic disc. A timer cord features 6 settings for therapeutic diffusion lasting from 50 minutes to 9 hours. The Whisper cleans easily, runs quietly, conserves oils, and functions with durable replacement parts. This high-quality machine is a worthwhile investment in your family's health—includes a 1-year limited warranty.

Contents: 1 diffuser, 1 timer cord, and 5 reusable/disposable oil and water cup liners. (Click here to view replacements parts.)

Diffusion: Ultrasonic.

Dimensions: 8" tall x 3½" wide x 3½" deep.

Instructions: The first time you use your new Whisper diffuser, fill the base and liner cup to the fill lines with tap water. Set the timer to the "50m" setting, and let the diffuser run until it produces a good quantity of mist. This will cleanse the mechanism of any oils left over from the manufacturing process. It may take the full 50 minutes to complete this cleaning process.

Features and Specs

NOTE: Proper use of your diffuser will ensure optimum performance and longevity. Make sure you understand how the diffuser functions before operating. This diffuser contains several important parts:

Water Tank and Ultrasonic Disk:

  • Only water is to be placed in the base, never oil. The Ultrasonic Disc in the base of the diffuser vibrates at 2.5 million times a second, creating a mist of ultra-fine microparticles. Adding oils to the base can interfere with this operation. The oil goes in the flexible liner cup, mentioned below. Water is needed to trigger vibrations in the ultrasonic disc and the diffuser will not operate without it. Checking the water levels after each diffuser cycle is a good practice. Ideally, water should be changed every other day, or once a week at the very least. Regular tap water is needed for the diffuser to mist properly as it requires minerals in the water to operate.
  • When the water level falls below the water level sensor, the diffuser turns off automatically. Keep the water level between the minimum and the maximum lines located on the sides, inside the base, preferably just above the minimum line. Water level can vary upon altitude, so you may need to adjust the water level between these lines for maximum mist output.
  • If the diffuser isn’t misting properly, adjust this water level to find the optimal level for your altitude. After finding the optimal water level for your location, you can use a permanent marker to mark this level on the side of the tank so you can easily refill the tank to the correct level.

Flexible Liner Cup:

  • The flexible liner cup stores both water and oil. This liner prevents oil from reaching the ultrasonic disc and interfering with its vibrations. Adding just the right amount of water is essential for proper operation. Use the included measuring cup to fill the liner with water, then insert 2-6 drops of essential oil. Remember that the oil goes in the liner cup, never in the measuring cup or the water tank in the base of the diffuser.
    NOTE: Drier climates may need an additional 2-3 tsp. of water if the water runs out before the diffuser finishes a cycle.
  • Should your diffuser be performing below its norm, it’s also a good idea to ensure correct water levels in the plastic liner cup. Sometimes smoothing the cup with your finger can help the mist disperse properly and prevent air pockets.
  • This plastic cup has been tested to work with the strongest oils, like lemon and cinnamon, and has a recommended usage life of 2-3 months, but may last longer depending on usage. Inexpensive replacement cups are also available at AromaTools.

Splash Guard:

  • The round splash guard keeps water inside the diffuser. Keep it in place when operating the diffuser to keep water from entering the corner holes and draining out the bottom.

Clear Cover and Directional Nozzle:

  • The clear square cover and directional nozzle direct the mist output of the diffuser. Do not attempt to remove the nozzle after attaching it to the clear cover as it may cause the cover to crack. If you need to change the direction of the mist, rotate the square clear cover and directional nozzle together.


  • The timer can be set to run with continuous output for 50 minutes or off and on for up to 9 hours. Press the power button to turn on the timer. Then, use the SET button to select your interval. Interval modes will set the diffuser to output for 15 seconds with varying rest periods starting from 15 seconds up to 2 minutes. Options include: 50 minutes continuous, 2 hours of output with 15 seconds of diffusion and a 15 second rest period, up to 9 hours of output with 15 seconds of diffusion and a 2 minute rest period.
  • The diffuser is designed so that the water in the cup lasts the duration of each timer setting.

Blue LED Light:

  • The blue LED at the base of the diffuser can also be turned on and off. Make sure there is no water in the diffuser when turning the base over to access the switch or be careful lifting the diffuser so that no water leaks out.

Cleaning the Diffuser:

  1. Make sure the diffuser is unplugged.
  2. Empty water from the flexible cup and water tank by pouring it out the notched side of the diffuser.
  3. Using a soft, damp cloth, wipe out the inside of the water tank, the exterior of the diffuser base, and wherever else may be needed.
  4. Poke the cloth through the directional nozzle to clean it without removing it from the clear cover.
  5. Place a small amount of alcohol in the flexible liner cup. Dip a Q-tip in the alcohol and gently clean the ultrasonic disc in the base of the diffuser as well as the flexible liner cup.
A disinfecting wipe or damp paper towel with cleaning solution works well on tough oil residue. However, cleaning solution with Lemon essential oil could damage the plastic, so use standard precautions if you are used to cleaning with Lemon essential oil.
Frequent cleaning will keep your diffuser looking new and allow you to enjoy its long-lasting performance.


  • Make sure you are placing water in 2 places - the flexible liner cup and in the base of the diffuser. Oil should only go in the flexible liner cup.

  • If you want to use distilled water, that is fine IF you add a pinch of salt to the water in the base. The diffuser is designed to use the minerals in the water to create the vibrations. Distilled water doesn't have minerals and will not create mist unless you add some minerals by putting a small pinch of salt in the water. Otherwise, tap water works just fine.

  • You can use the flexible liner cup up to several months. Some have used it for up to a year! It all depends on how much you use the diffuser. However, if you think the diffuser isn't misting as much as it did before, try putting a new cup in and see if that fixes the problem.

  • You can mark the flexible liner cup or base of the diffuser with a permanent marker to help you easily refill right to the water line you have found works the best. This saves time in trying to find your measuring cup each time you start a new cycle. However, do keep your measuring cup with your extra flexible liner cups so you can easily mark those when you switch cups.

  • If your Whisper sounds noisy, that is usually caused by oils getting on the vibrational chip, causing corrosion, or by water and oil getting in the motor and fan when the unit gets tipped over. Cleaning the Ultrasonic Disk in the base of the diffuser may help. Never put oils in the base of the diffuser!

  • Sometimes with a lot of usage the directional tip can become sealed to the square top making it difficult to remove. This is due to erosion caused by the oils while diffusing. DON'T TRY TO REMOVE IT. Leave it alone and just rotate the square top if you need to change the direction of the mist output.

Frequently Asked Questions

My diffuser is not misting properly, is it defective?

If you feel your diffuser is not misting correctly, here are a few things to check before thinking it is defective:
  • First, take note of the water level in the base of the diffuser. It is recommended to keep the water between these two lines. The recommended amount is just above the minimum line, but this can vary upon location and diffuser. Too much or too little water can change the output of the mist.  You can experiment with different water levels, using the max and min guidelines, to see what works for your environment.
  • Be conscious of the condition of the flexible liner/cup.  Smooth out the flexible liner as best as you can with a finger to reduce the risk of air pockets forming. The included measuring cup is used for filling the liner cup. Make sure not to fill beyond the indicated line.  Introducing too much or too little water may cause the diffuser to mist improperly or run out of water before the timer finishes its cycle.
  • Also, make sure the diffuser is put together properly with all the pieces included as described in the User Guide.  Setting the diffuser to output continuously is a good way to verify that things are functioning normally as the other settings cause the diffuser to output at various intervals.
  • Cleaning the Ultrasonic Disc in the base of the diffuser with a Q-tip and a little alcohol could solve the misting problem if the diffuser has slowly reduced its output over time.
My diffuser is ‘leaking’ and water is coming out the bottom, what should I do?

  • If you notice water coming out of the diffuser, it’s likely the splash guard is not in place.  Make sure all the parts are assembled properly as shown in the user guide instructions and make sure water amounts are at the specified levels.
My cup has melted!

  • Putting too much water in the flexible liner cup can weigh it down preventing proper vibration which risks melting. Using poor quality oils in the liner cup could ruin it and could potentially damage your diffuser.  We recommend you use certified pure therapeutic grade essential oils--like those from doTERRA- for which the product has been tested for optimum compatibility. If the cup melts or becomes deformed it will need to be replaced.
How do I turn the blue light off?

  • At the bottom of the base of the diffuser is a switch that allows you to turn the blue LED light on and off.  Make sure there is no water in the diffuser when turning the base over to access the switch otherwise be careful lifting the diffuser so that no water leaks out.
Where do I put the oil?

  • The only place oils should be added is in the flexible liner cup.  Do not put oil in the base of the diffuser. If oil is placed in the base of the diffuser, damage can occur to the ultrasonic disc. Also, never add oils to the measuring cup before filling the flexible liner cup. The measuring cup is not designed to be oil-resistant and is for measuring water only.  The flexible cup is specially designed to hold oil and has been tested with undiluted lemon and cinnamon oil left in the cup for 2-3 weeks without damage.

My friend told me I should get a whisper diffuser because she has one and loves it. I bought the diffuser not really sure how I would like it. I have to say I absolutely LOVE this diffuser! It's easy to use, works really well and looks nice. Just make sure you don't put too much water in it or it wont mist. I love the light and option to turn it off. Not to mention the timer is awesome! I just put some water in with a few drops of essential oil and turn on the timer for say 5 hours and it's good to go. I love this diffuser so much I even bought a second one for my bedroom :0) (Posted on 6/26/2018)

We've had the Whisper for a few months. I have not been happy with it from the get go. You have to be Houdini to figure out the EXACT amount of water to use in it. One month after putzing with the diffuser, I decided to send it back for an exchange. I thought it could have been defected. Aromatools, sent me a new Whisper(which was great) and they said the first one was defected. Well, now, after using the new diffuser for 2 weeks, the thing BARELY puts out mist. I've changed water levels 3 times in it this morning and it's not misting anything now. I'm just gonna say that this diffuser STRESSES ME OUT! So frustrating. (Posted on 6/26/2018)

I have owned multiple diffusers and also have friends that have had all different types of diffusers. This one is by far my favorite.

It is totally maintenance free with the disposable cups and easy to fill reservoir. Nothing gets gunked up or accumulates residue like my previous diffusers. The different time cycles are awesome and so convenient. And it's an added bonus that it sits nicely on my kitchen counter without being an eyesore. I will also be purchasing one for our downstairs living space and also the bedroom. You really cannot go wrong with this one! (Posted on 5/21/2018)

I have two of these for upstairs and one for downstairs. I love the fact that I can set the timer for different time frames AND the fact that I can turn off the light is a HUGE plus! My only complaint is that the "neck" needs to be longer! The way it's designed, the mist just doesn't get high enough into the air as it is dispensed. I "fixed" this by getting a 3/4" PVC pipe and cut it for a 3' length and stuck it in the neck of the unit and put the nozzle at the upper end with a 3/4" PVC coupler. Looks ugly....but I LOVE the results! I wish they'd come up with clear pipes of different lengths to buy as an accessory. It would be prettier. (Posted on 5/2/2018)

I have used four different diffusers, and this is definitely my all-time favorite. It's easy to use, it doesn't clog, you can turn the light on or off, there are a lot of different options for how long it runs, etc. It seems to be well made and is very quiet. (Posted on 4/30/2018)

I got this diffuser a couple weeks ago and I absolutly love it!

I found if I put too much/too little water in the main basin, it will not produce any mist. I put the water just above the minimum water mark, enough to cover the metal sensor. I put 80cc of water in the flexible liner with my oils, 4-6 drops usually, and set it to run for the full 9 hours.

I have yet to have a problem with it! I like it because it's no mess, no fuss just refill and go. You also have the option to turn the blue light off if you run it at night.

Can't love this diffuser more :) (Posted on 4/30/2018)

I love that my family and I can use the Whisper diffuser for up to 9hrs so when we do get sick it will run all night without getting clogged. It's one of the easiest, maintenance free diffusers I have ever used. Creates wonderful aroma, you can turn the blue light on and off. Definitely recommend!! (Posted on 4/17/2018)
Review by:
I really liked this diffuser and purchased a second one. The first one was purchased several years ago and is still working without any problems. I did have a problem when I first started using it with getting the water level correct. Since then no problems. On both units the spray nozzle tip and sq outer cover cracked. When I purchased my second one I purchased an additional nozzle and cover. I would recommend these units however I would also recommend purchasing additional nozzle and sq outer cover. They are not expense but with the cost of handling and shipping it makes them expense to replace. I wished I had purchased 2 nozzle and covers. Both times they broken in the area where the nozzle connects with the top. (Posted on 4/16/2018)

I submitted a one star review and was told I could edit it, but can't figure out a way to edit. So I'm updating my one star review with a separate 4 star review. Note that if you follow the directions and add 80 ML to the cup it may not work. Try adding about 70. I did that and the steam came POURING out again. It really does a great job of filling the room. However, the amount of water is small and is used up fairly quickly in about 45 minutes. That's the only reason I gave it four starts instead of five. Powerful little unit! (Posted on 4/2/2018)

I can't figure out what is wrong with the top pieces on this. When I first used it it filled up 900 square feet and seemed awesome! The motor is still running and it's bubbling inside, but nothing comes out...or barely anything comes out. I found that if I put the lid on halfway that temporarily fixed it, but now it won't work no matter how I fiddle with it. Really disappointing as I thought this was going to be THE ONE as for as diffusers to. And for an hour, it was!

The ""Whisper"" is affordable, attractive, easy to use, effective, small, and sleek. I absolutely LOVE the strong output and the timing device.

I originally bought the diffuser for my small bedroom but was pleased to realize that I could smell the essential oils throughout my entire home! This certainly was not a purchase that left me disappointed!

With regard to AromaTools, I would DEFINITELY purchase from them again. Originally, I had selected the standard shipping option. Within a day, I received a personal email from Craig in Shipping indicating that he had found a way to save me money by using USPS. Not only did he save me a little over $5, but I also got the package sooner than expected. EXCELLENT SERVICE!

I am an incredibly discerning shopper and I NEVER leave positive comments on websites (I just don't have the time)---the Whisper and AromaTools deserves the nod and the thanks!

You will not be disappointed! (Posted on 3/15/2018)

I have owned this diffuser for over 5 years now and I love it! I own several and it is my favorite one. I love that you only a few drops will last for hours and that the oils are not put directly into the diffuser. Some oils stain the diffusers when you use them but this since the oils are put into a separate plastic insert they do not ruin the diffuser- and you can buy replacements inserts and other parts to the diffuser when they get too stained. I also love the different run times options on the power cord. Definitely would recommend this product! (Posted on 2/8/2018)

I like this diffuser because it is silent and the oils are not in direct contact with the internal working parts of the diffuser. I like to use oils that have citrus components like On Guard and those oils can cause problems for the internal working parts. As this diffuser had them separate it is better for the diffuser.
I also like the different preset timers that you can choose as well as the option for the light to be in or off. Overall I think this is a good diffuser. (Posted on 2/6/2017)

I've had two of these Whisper diffusers for right at 5 years using them 9 hours almost every day. They're beginning to wan with the diffusing power so I ordered two new ones and hope they last as long. They're quiet and diffusing essentials is the way to go instead of candles w/fragrance made from chemicals. If this product had a '10' star rating I'd be clicking it instead of the '5' star.

Purchased this diffuser as a Christmas gift for my wife. I arrived via ground shipping in good order. There was no tracking information provided so I wasn't sure when delivery would be made, normally useful information. The diffuser is aesthetic and does what the manufacturer claims.
