What are the differences between ultrasonic diffusers and CSAT cold air atomizers?

diffusori a ultrasuoni o atomizzatori ad aria fredda, quale scegliere?

A diffuser is a great way to scent a room or enjoy the therapeutic benefits of essential oils, whether at home or in the workplace.

When it comes to modern diffusers, there are several options. Old-fashioned diffusers rely on a candle or other heat source to heat water in which essential oils are dispersed, which means risking losing the therapeutic benefits or distorting the essences, as the heat can damage the volatile compounds. Diffusion by natural evaporation, on the other hand, simply takes too long and is therefore ineffective. ultrasonic diffusers or cold air atomizers, which should you choose?To get the most out of these oils, you need to find a way to distribute the compounds quickly and intact.


This is where two cold diffusion systems come in. Ultrasonic diffusers are the most common and use water to disperse fragrances. Essenzapura's atomizing diffusers, on the other hand, use waterless cold air CSAT technology. Let's look at the important differences between the two.

Both ultrasonic and CSAT cold air diffusers use a heat-free medium to disperse the fragrance, preserving the delicate compounds in essential oils and purifying the air. However, the method in which they do this is different. With an ultrasonic diffuser, tiny vibrations vaporize the water in which the essential oils are diluted. This cold vapor is what distributes the fragrance in the air.

In cold air diffusion with CSAT technology, air at room temperature pushes pure essential oil, without water, into a nebulizer at high pressure. It is this nebulizer that distributes an extremely fine vapor of atomized particles throughout the space quickly and efficiently.


The most important differences are twofold: the cold vapor of ultrasonic diffusers consists mainly of water, so it is very heavy. In fact, after some time of operation, the area around the diffuser remains wet or at least damp, possibly damaging furniture. Essenzapura diffusers, on the other hand, vaporize only pure oils without water. The second major difference is in the duration of scenting. The water vapor of ultrasonic diffusers, being very heavy, tends to fall to the ground immediately. Therefore, the scent is perceptible only as long as the device is in operation. Diffusers with CSAT technology on the other hand produce such tiny particles that they remain in suspension for hours even after the device is turned off.


For these reasons, CSAT cold air diffusers have become the preferred means of diffusing scents in many homes and workplaces.
