Conventional Candle or Tea Light Diffusers

A common aroma diffuser in Malaysia, these are the types of diffusers available in several gift shops and stores.

They come with a water container so you can drop a few drops of essential oil and then light a small candle or tea light beneath. The candle will heat up the water and diffuse the essential oils. The addition of a candle or tealight also creates a vibrant atmosphere.

The only problem with these types is that you cannot control the temperature of the water and essential oils. The process at times can burn off the essential oils if they are exposed to high temperature or heat for long, leading to oxidation and degrading the healing potency. It is also dangerous as it may catch fire from the naked candle flames.


A nebulizer flows through an air container across a small receiver that connects to the depository of the essential oil.

This high-velocity air transforms the oil into smaller particles which are then diffused throughout the room. This is by far the most natural and traditional way to diffuse essential oils without heat. The only drawback is that they need a small electrical motor to generate the jet of air and thus they can be a bit noisy. Oshadhi has two kinds of nebulizer available for sale – The Crystal diffuser with a wooden level and the Cool Breeze Micro-diffuser which is portable and activated by a 12-volt USB connector that works efficiently in a car.

Fan Diffusers with Fresh Air
