Aroma lamp with essential oil

Aroma lamps, or diffusers, are used to diffuse essential oils in aromatherapy and esoterics.

There are four different types of diffusers:

Nebulizer[edit]

Is a device that doesn't 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.

Ultrasonic diffuser[edit]

Basically, it is the same as Nebulizer, but it uses water. This makes the mist not so concentrated. This device can be used as a humidifier, that can be very helpful especially in the winter.

Evaporative diffuser[edit]

This 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[edit]

Usually, a candle driven lamps that use 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.[1][2][3]


Certain plug-in nightlight units made by companies such as Air Wick are used in combination with glass bulbs of scented oil, filling a room with fragrance and light.
