COOSA Ultrasonic Aroma Diffuser – Construction, Operation & Maintenance
The COOSA Ultrasonic Aroma Diffuser is nicely constructed with a polypropylene + ABS plastic base and a metal and glass cover. Its unusual looks set it apart from most other essential oil diffusers.
Its aesthetic appearance has earned it rave reviews. ‘Hauntingly beautiful’ describes it perfect.
The last thing you want to do is spend too much time setting up your diffuser. With this unit, you won’t have to do that.
The COOSA Ultrasonic Aroma Diffuser is easy to set up and safe to use.
Fill water up to the max line that is indicated on the unit. This line indicates the 100ml mark. Do not fill water above this max line. Excess water will shorten the run-time and hamper the mist production.
Add 1 – 3 drops of your favorite essential oil to the water.
Place the lid and canopy back over the unit, making sure the lid sits properly so the body is sealed.
Plug it into an electrical outlet.
Press the left toggle button to the ‘on’ position to turn it on and to the ‘off’ position to turn it off.
Press the right button to change the color of the diffuser.
Set the timer using any one of the four smaller buttons. The timer options that are available are .5H (30 minutes), 1H (1 hour), 2H (2 hours) and 3H (3 hours).
You do not even have to worry about turning it off when the water runs out. The unit senses when there is no water left and shuts off automatically.
- Watch that water level. Make sure it is below the 100 ml max line
- Always keep the lid on when the diffuser is working
Regular maintenance will help extend the life of any aromatherapy diffuser, and the COOSA Ultrasonic Aroma Diffuser is no different.
Nothing to stress about though. Maintaining this unit is easy. You just have to remember these two things:
- Do not leave water in the unit when it is not in use. Throw away any remaining water and let it dry between uses.
- Clean the water chamber with a clean dry cloth before use to remove any dust that may have settled in the unit.
How the COOSA Ultrasonic Aroma Diffuser Essential Oil Diffuser Works
When you plug the unit on, it emits a light mist that is scented with the essential oils that you have added to the water.
The cool mist adds gentle moisture into the atmosphere, giving the room a spa-like ambience, while the essential oils that you have added will transform the mood of your space.
Which essential oils should you use in the unit? Here are a few ideas to get you started out:
- Adding citrus oils will leave you feeling refreshed and energized.
- Floral scents such as lavender and chamomile are perfect for when you want to relax and wind down.
- And for those times when you want to ramp up the mood in the bedroom, add a few drops of any aphrodisiac essential oil or better still, use a romantic essential oil blend.
The mist is just enough to add a little humidity to the air without creating a pool of excessive water around the unit
You can choose how long you want the unit to run by choosing the 0.5H, 1H, 2Hs, 3HS buttons. The unit will stop working automatically when it reaches the selected time setting or when the water runs out.
The ultrasonic technology ensures that the unit runs quietly without any annoying humming or buzzing. You can use it while you sleep or work and it will work silently in the background so you get the benefits of aromatherapy without being disturbed.
Choose from 7 Lighting Colors to Create the Right Ambiance
The 7 color changing LED lights are another fabulous feature of the COOSA Ultrasonic Aroma Diffuser.
Press the button on the right side of the unit to change the color depending on the atmosphere you are trying to recreate.
I know I’ve been talking a lot about this diffuser for Halloween but what’s cool about this diffuser is that you can simply change the light color to create a completely different mood.
While purple and dark blue may be the colors of choice for your Halloween setting, the green or light blue light will create a nice soothing atmosphere in the room.
The red light will instantly create a sultry, passionate ambiance especially if you’ve added a few drops of the right essential oils.
How the Waterless Auto-Off Function Works
The Waterless Auto-Off function is really handy. When the unit detects that the water has run out, it automatically powers off to protect the components from damage.
This means you can put it on with a relaxing essential oil to help you fall asleep and you don’t have to worry about waking up to switch it off.
It will power off automatically when the water runs out.
What You Will Love About the COOSA Ultrasonic Aroma Diffuser
From looks, performance, and convenience to ease of use, durability and easy maintenance, there is a lot you will love about the COOSA Ultrasonic Aroma Diffuser.
It is one of the more versatile essential oil diffusers in that you simply have to change the LED light color to transform the look and ambiance of the room.
It is more than just a diffuser. It also doubles up as a humidifier, which can make all the difference during those dry winter months.
The unit runs quietly without any annoying sounds. Add a few drops of the right oil and you will get the benefits of the essential oil while working or sleeping without getting disturbed.
You can even run the unit without the lights on, which is particularly useful if you like your bedroom to be completely dark at night.
Alternatively, you can switch only the light on so it acts as a night lamp without the diffuser function or you can use it as a humidifier on its own without the essential oils.
You don’t have to set a reminder to put the unit off. When the water runs out, the Waterless Auto-Off function kicks in and shuts it off, preventing any damage to the components.
