Air Refreshers/Humidifiers vs Heat Diffusers vs Ultrasonic Diffusers
excerpted from Kathleen Henderson and Christina Anthis
Most air refreshers/humidifiers run continuously. Essential oils, especially citrus oils, break down plastic. Most humidifiers are not constructed to hold up to essential oil usage. Diffusers are specifically designed to handle essential oils. Humidifiers are made to handle water. Humidifiers do not break essential oils down into that tiny size that allows for greater absorption by the body. Humidifiers can disperse essential oils, but a diffuser will nebulize them into miniscule particles that can be more readily inhaled and absorbed.
Heat Diffusers – whether the types that are electric or use tea-light candles – are great for spreading a lovely scent throughout your home. It’s mainly for pretty smells only. Unfortunately, most of these oils that you can burn contain more chemicals than essential oil. If you are wanting the therapeutic properties of essential oils then heat should be avoided. Heat alters the chemistry of the oil, removing any therapeutic properties it might have had.
A good diffuser uses cold air to break essential oils into tiny particles and disperse them into the air. As we inhale, the tiny particles of oil enter our body and get to work affecting our cells in a positive way. Diffusing isn’t just for creating a nice smell. When high quality, therapeutic grade essential oils are diffused, they actually carry powerful health benefits
Ultrasonic diffusers are the best all around choice for therapeutic use of essential oils in your home. This diffuser uses electronic frequencies to create vibrations in water, that are carried to the surface where the essential oils are floating. The vibrations vaporize the essential oils and disperse them into the air without using any kind of heat at all.
