Understanding how essential oil diffusers work – and how to clean them will ensure a longer life for your diffuser.
Essential Oil diffusers are largely misunderstood in terms of how the ultrasonic technology works.
When you place water in the water chamber and place aroma oil or essential oils in the water, the oils will float to the top and sit there. Activating the diffuser essentially forces a radio signal through the water.
Following activation of the radio signal, the water – through its own natural impedance response to the ultrasonic energy transmission, is caused to gently vibrate. This vibration causes a breakdown of the essential oil molecules and the water molecules, allowing both to dissipate into the surrounding area in the resultant cool mist.
Using ultrasonic energy to transmit essential oil or aroma oil is a very effective way of diffusion because it requires no heat generation. Application of heat to release essential oils is another way of releasing their scent, but the heap itself can cause a denaturing on the oil’s properties.
Because ultrasonic diffusers use no heat, they allow full integrity for the properties of the oils.
This makes the diffuser very safe to use around young children and pets – a commonly asked question. The diffusers do not generate any heat whatsoever – even the vapour mist, which looks like steam, is cool to touch.
Ultrasonic diffusers are also very effective in that they have an auto stop function on depletion of water in the chamber – so they tend to last a lot longer (no burnout).
On release, the vapour has a positive effect on surrounding air – adding positive ions to the surrounding space as well as the lovely scent and the medicinal properties of the essential oils – much like the relaxing and health-giving experience of being near the ocean (also a powerful emitter of negative ions), diffusers deliver negative ions to the rooms they are used in – allowing a freshness and a somehow cleaner feel to the air.
Positive ions have the ability to neutralise mould spores and improve energy. Anyone who is sleeping poorly, feeling overly stressed or who is feeling under the weather generally will benefit from diffuser presence.
