Different diffusers have their own ways to work, from the original essential oil diffusers which use heat to evaporate essential oils to the latest models which use ultrasonic technology, great changes and progress have taken place in this industry. Here I’ll introduce 4 main technologies the essential oil diffusers come with at present.
Generally speaking, evaporative diffusers use quiet fan blow the oil and make it evaporate into the air.The drawbacks of this kind of diffuser are the lighter elements of the oil that are on the top layer disperse initially, and the heavier components follow.also, some old models of fan diffusers may be noisy, but some updated models work quietly and smoothly.
Heat diffusers generally use a small candle to heat, or electricity to generate heat.Working silently is one of the biggest advantages for heat diffusers, a large number of aromatherapy fans prefer heat diffusers because of that. Its key problem is that the heat can change the chemical composition of the oil.
Ultrasonic diffusers come with advanced ultrasonic technology to breaks the water and essential oil into extremely fine micro-particles without using heat. It ensures the integrity of the essential oils’ beneficial molecular structure and allows for ease of healthy bodily absorption.
A nebulizer or atomizer offers the advantage of dispersing a relatively large quantity of essential oils into the air rapidly. The principle is similar to that of an electric perfume sprayer. Nebulizers disperse tiny droplets of oil into the air by suctioning from the oil source bottle.
