. They may project the oil into the air by heating it, letting it evaporate naturally, or nebulizing it using compressed air or ultrasonics.


Evaporative diffuser

An evaporative diffuser is a device that uses a pad or a filter to diffuse the essential oils. One of the disadvantages of this tool is that the light elements of the essential oils will be circulated around the ceiling first and will only come down at the end of the process.


Heat diffuser

A heat diffuser contains a small candle under a bowl to vaporize a mixture of water and oil. This device is very cheap and doesn't need a special maintenance, however, the heat can change the chemical structure of the oils.England, A. (2000). Aromatherapy and massage for mother and baby.

is a device that does not use water or heat as other diffusers. The bottle of essential oil is attached directly to the nebulizer. As a result, the unit uses 100% pure essential oil. The benefit of using this device is a strong concentration of the essential oil. However, it can be noisier than the other devices depending on the specific model in use.


Ultrasonic diffuser

An ultrasonic diffuser is the same as a nebulizer, but uses a water/oil mixture. This makes the mist not so concentrated. This device can be used as a
