Ultrasonic Diffusers are the magical key to unlocking a scent-infused atmosphere in your home. Using ceramic plates and ultrasonic vibrations, they transform essential oils into micro particles that disperse like mist surrounding a waterfall – all without any odor or residue. And with their astonishing 2.5 million per second oscillations creating an aromatic fog, you can easily refresh your space anytime!

  • Make sure your diffuser is plugged in, the led light and mist will turn on immediately once the power is coming from your source
  • Make sure to use fresh tap water, not distilled or purified water. We design the diffuser for tap water, because tap water is the key to success because its mineral content helps produce the vaporization effect.
  • Clean your diffuser to keep it running smoothly, it’s important to break up the oil residue that is clogging its ceramic disc. A simple wipe down with warm water and a soft cloth will suffice for regular cleaning; however, if you need to perform some deep-cleaning then use cotton swabs dabbed in rubbing alcohol on tough areas!


Some Noisys are normal from the motor or fan strength during operation-such as the water moving inside- if you find yourself hearing any strange sounds coming from your unit that aren’t normal during operation please reach out to our Customer Care Team immediately and discontinue use.

The water is not heated internally but will become hot after a few hours of use. Factors that affect the temperature of the water include the ambient temperature, the heat of the water placed in the unit, and the current flowing through the unit. It is normal for the water temperature to rise over time. Especially if it lasts all day. The water should not exceed 30 to 40 degrees Celsius.

  • Keep your ceramic plate clean,  use cotton swabs dipped in warm water for routine cleaning and use alcohol-soaked swabs for those deep cleans that need to break down the oil.
  • Make sure there’s water inside the machine until it’s slightly below the fill line – otherwise this machine won’t even start!
  • It is possible that water has gotten into the machine’s circuit board and caused a malfunction, and it is best to replace the unit with a new one


make sure your vapor insert is flipped the right way up, and that you have all necessary components – including a directional nozzle. If anything’s missing or misplaced, be sure to request a replacement!

PS:To ensure proper functioning, some units require their vapor insert to be securely attached and positioned correctly. If the issue persists, double check that these components are in place!

Do not overfill an aroma diffuser over its max fill line, the capacity of each diffuser is different and detailed in each package, but as a guideline, we currently have  several different ways to indicate the maxi fill line of our air diffusers.
