There are multiple types of aromatherapy diffusers that you can consider, all based upon your needs. All of them do the same job, however, there are different ways that various types of aromatherapy diffusers go about the process of spreading the oil molecules through the air. Some use heat, some use fans, and some use other more interesting ways of spreading aroma throughout a room.

Let's detail the different types of aromatherapy diffusers that one can consider.

Aromatherapy diffusers that use heat work much like a candle does. The heat from a flame or electric filament breaks the bonds of the essential oil molecules and allows them to freely move throughout the room. Compare this to how a scented candle works, in that normally you're not able to smell much of the candle when the wick isn't lit. Light the wick, and suddenly the room comes alive with aroma. Such is it with heat-powered aromatherapy diffusers.

Electric fan aromatherapy diffusers are a bit less effective in spreading a strong aroma, however they tend to do a good job at spreading a weaker aroma throughout a larger room. These types of diffusers may be a bit more expensive than other types that might only use a flame, for the simple purpose that it's a more complex system and takes money to manufacture. For those who are interested in being more environmentally friendly with their aromatherapy needs, it might be a better idea to stay away from the electric types and use a diffuser that uses heat. Also, electric fan aromatherapy diffusers aren't silent, which might be a problem for some people who use aromatherapy for relaxation purposes.

Another form of aromatherapy diffuser is called an atomizer. When you're thinking about how an atomizer works, think about a bottle of perfume and how that works. The essential oil is pushed through a small screen that breaks up the oil into smaller drops. When the oil moves into the pump, the droplets are sprayed in a fine mist into the air. This is an effective method of spreading an aroma throughout a room, however, unlike heat or fan-powered aromatherapy diffusers, this type of diffuser tends to work in a smaller room to cover a smaller area.

I hope that this article has cleared up any questions you might have had about aromatherapy diffusers.
