The easiest and simplest way to use essential oils, other than inhaling directly from the bottle, is through an aromatic diffuser. A cold air diffuser uses room-temperature air to break the oil up via a nebulizer, which breaks up the oil into a micro fine mist before dispersing it into the air.
When essential oils are put into the air, they remain suspended for several hours to freshen and improve the quality of the air, as they are able to rid the environment of nasty odours and dangerous aerial bacteria. The anti-viral, antiseptic and antibacterial properties of the oils can help to reduce fungus and mould and kill bacteria.
The oils also reach our brain via the olfactory nervous system and have a positive impact on our emotional, physical and spiritual well-being.
The reason why you should use a diffuser over an oil burner is so that you experience the therapeutic benefits of the oils. Cold-air diffusers disperse the oils into the air without heating them or burning them. Candles and oil burners can render the oil therapeutically useless. While they can look nice, serene and calming, you are not getting any therapeutic benefit when you do so. This is fine if you just want a nice smell, but to get the most out of your oils, its best to use a diffuser as essential oils contain sensitive volatile aromatic compounds which can be damaged from the heat of an oil burner.
I recommend the doTERRA petal diffuser to people getting started with essential oils, as it is a small, convenient diffuser with a far-reaching (330 square feet) mist. It also has a 1, 2 or 4-hour timer setting and can double as a night-light. This diffuser is perfect for both novice and experienced essential oil users who want a reliable, easy-to-use essential oil diffuser.
