Worth knowing before use
How to clean and maintain a diffuser?
According to the manufacturer's recommendations, to ensure optimal performance of the diffuser:
- Clean the tank after each use.
- Once a week, rinse the inside thoroughly with warm water (max 40°C) and a mild detergent.
- Do not use harsh cleaners or acidic detergents.
- Be careful not to let water get into the ventilation holes.
- If the ventilation system is accidentally flooded, wait 6 hours before using it again.
Tips for using your diffuser
- Always place the diffuser on a stable, flat surface.
- Fill the tank with water below the maximum level (MAX).
- Add 3–5 drops in a diffuser per 30 m² room.
- Place the ceramic lid on gently to avoid damaging it.
- Plug the power adapter into the socket and then turn on the device.
- The power button activates the mist and LED backlight.
- The light button allows you to choose one of 7 colors or turn off the backlight completely.
Diffuser operating modes:
- When you press the first button, the continuous mist starts.
- Pressing the button a second time turns on the intermittent mist - I particularly recommend this function because it ensures a gentler, longer diffusion.
- The second button allows you to turn on or change the backlight color, or leave the diffuser without light.
Additional recommendations
- Use soft water or bottled water – distilled water is not recommended.
- Always unplug the diffuser after use.
- Essential oils may cause discoloration – if they come into contact with the housing, wipe the surface immediately.
- Take care of your diffuser – with proper care, it will retain its beautiful appearance for longer.
Does the diffuser need regular cleaning?
Yes. Regular cleaning helps maintain the proper operation of the device and the intensity of diffusion. In ultrasonic diffusers, mineral deposits from water are most commonly accumulated, while in nebulizing diffusers, oil residue builds up in the nozzle. With regular use, it is advisable to clean the diffuser every 1–2 weeks or according to the manufacturer's instructions.
Why might a diffuser smell less over time?
The most common causes are mineral deposits on the ultrasonic membrane, too much essential oil in the water, dried oil residue, or using thick, resinous, or low-quality oils. In most cases, a thorough cleaning of the device and using the appropriate amount of essential oil recommended by the manufacturer will suffice.

What kind of water is best to use in an ultrasonic diffuser?
It is best to use the water recommended in the instructions for the specific model. In many cases, boiled, filtered, or bottled still water works well because it reduces scale formation on the membrane. Demineralized water can further reduce mineral deposits, but it should only be used if permitted by the device manufacturer.
