A diffuser, also known as essential oil diffuser/oil diffuser/aromatherapy diffuser, is a device that helps to disperse broken down molecules of the essential oils into the air at a comfortable concentration, filling up and transforming the space into a tranquil spa with the heavenly scents of essential oils. This low effort device doesn’t just help you to breathe easier but can be easily incorporated into self care routine, helping to unwind after a long day. There are different types of diffusers for you to choose from.


Ultrasonic diffusers work by using vibrations to break down the molecules of the essential oil and dispersing it into the air like a fine and moist mist, the added moisture makes it ideal during cooler days or seasons. When working with an ultrasonic diffuser, it is compulsory to dilute the essential oil with water and to clean the plastic parts meticulously as oils can be corrosive to plastic. Here are a few popular ultrasonic diffusers:

Nebulizer diffusers work by diffusing the essential oil into a mist by using compressed air. A vacuum pulls the oil to the surface of a distribution tube, inducing the living space to be filled with a burst of aroma. Nebulizer diffusers are ideal for eco-conscious and low maintenance consumers as not only are they plastic-free, they don’t require water like ultrasonic diffusers and they also don’t require any heat.

Portable diffusers are ideal for those who are constantly on the move. Portable diffusers are often smaller in size (often palm sized) compared to ultrasonic and nebulizer diffusers and rechargeable via USB. Portable diffusers vary from brand to brand. Some require water to be added into the diffuser while some do not, and there are also some that comes with a small bottle of essential oil while others come with the diffuser alone.

How to Clean Your Diffuser

Diffusers go hand in hand with essential oils for an enjoyable aromatherapy experience. They help to disperse the essential oils evenly into the air, creating a relaxing ambience. Between each use, clean it lightly by pouring out the infused water and refilling it with new water. At least once a month, do a thorough cleaning with your diffuser.

What is the importance of cleaning your diffuser?

  • Prevents and reduces the built up of mold and oil residue
  • Prevents overheating from lack of maintenance
  • Prevents clashing aromas from old oils
  • Maintain the quality of your diffuser for prolonged use and longevity
  • Keeps your warranty valid as it’s not damaged or in need of repair from improper maintenance

You don’t need a lot of tools or equipment to clean your diffuser. What you’ll need is:

  • Soft microfiber cloth/Soft cotton pads
  • Cotton bud/Q-tips
  • Rubbing alcohol/White vinegar diluted with water (1:1 ratio)

The acidic and anti-bacterial properties of white vinegar removes dirt, dust and stains, and if your diffuser is made out of wood (nebulizer diffuser), it can even help polish the wood and make it look like it’s brand new. Just don’t use white vinegar on hardwood floors and you’ll be fine.

You want to start with unplugging your diffuser from the power outlet, disassemble your diffuser and empty out any remaining water. Soak a soft microfiber or cotton cloth, or soft cotton pad in the diluted vinegar, squeeze out the excess and wipe the inside of the diffuser with it.

Alternately, you can fill up the water reservoir halfway and add about 1 teaspoon of vinegar, let it run for 5-10 minutes. The vinegar is diluted either way so don’t worry about the vinegar leaving a smell after. You can also use a few drops of dish soap mixed with water to clean the inside of your diffuser, make sure to rinse after.

The next step is to clean the ultrasonic chip with a cotton bud soaked in rubbing alcohol or diluted vinegar. The ultrasonic is very important as it is the operational muscle of the diffuser. It’s the part of the diffuser that helps to create the mist through vibrations, so you’ll want to pay extra attention to it.

After that’s done, you’ll want to wipe the inside of your diffuser dry with another soft microfiber or cotton cloth. You can also let it air dry if you prefer. Now that the inside is thoroughly clean, wipe the outside of the diffuser with diluted vinegar using a soft cloth or cotton pad.

Sometimes the dispersed mist will leave a residue on the outside of the diffuser. When neglected, it can lead to a built-up of a sticky residue on the surface of your diffuser. When you’re wiping the outside, make sure to be cautious around the electrical cords and connections.

When your diffuser is thoroughly dry and clean, you can reassemble it and prepare it for its next use. You may need to perform this deep cleaning method more than once a month if your diffuser is hotter than usual, the mist performance is weaker than usual, or if you noticed built-up at the ultrasonic plate. When in doubt, you can also contact the manufacturer.
