There are several types of aromatherapy diffusers, all of which are designed to disperse fragrant and therapeutic essential oils into the air. An aromatherapy diffuser can be used as a natural air freshener in a room or even in a car. Natural plant oils offer an alternative to synthetic fragrances that can cause allergic reactions in some people. As well as having a nice fragrance, pure essential oils can be used to promote physical and psychological well being. As the aroma molecules are diffused into the atmosphere, theyre inhaled into the lungs and absorbed into the bloodstream, where their benefits can take effect on the body and mind.

Aromatherapy essential oils can be used to produce a calming, refreshing or uplifting mood. Different oils have different aromas and uses. For instance, lavender oil is well known for its relaxing properties, whereas tea tree oil is used by many people to ward off symptoms of colds. Diffusion can be done in a number of ways. Essential oil burners are widely used. These involve a few drops of pure essential oil being diluted in a small bowl of water, which is then heated above a tea light. Some people prefer to simply add the oil to a bowl of boiling water, to avoid the risks of a burning flame. The heat helps to disperse the aroma into a room.

Other types of aromatherapy diffusers that use heat include light bulb rings and those that use an electric heat source. Using aromatherapy candles is another popular way to freshen a room. Fan diffusers, powered by either batteries or electricity, work by blowing air over a tray or pad of oil. A special aromatherapy nebulizer is believed by many aromatherapists to be an even more effective way to disperse oils. Nebulizers break down the oil into separate molecules, to make it easier for the lungs to inhale them. For a cheap and portable way to benefit from aromatherapy oils, clay pots are really useful. A few drops of oil added to the pot can slowly disperse through the porous surface to freshen the air in a room or in a car.

Essential oil diffusers are brilliant for freshening the air in a room and creating a welcoming atmosphere, without the use of any artificial chemicals.
