Ultrasonic or cold air diffusers?

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

A diffuser is a great way to scent a room or enjoy the therapeutic benefits of essential oils, 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 warm water in which essential oils are dispersed, which means risking the loss of therapeutic benefits or denaturing the essences, as heat can damage the volatile compounds. Natural evaporation diffusion, on the other hand, simply takes too long and is therefore not effective. 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 into play. Ultrasonic diffusers are the most common and use water to disperse fragrances. Essenzapura atomizing diffusers, on the other hand, use waterless CSAT cold air 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 found 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 water vapor is what carries the scent into the air.

CSAT Technology

Once the aroma oil is diffused through nebulization, a process that breaks down the essential oil into a fine, dry mist, it is diffused through the core of the diffuser using the air in your space. Our internal air filters ensure that no foreign particles or dust come into contact with the nebulized air, which results in a subtle and consistently scented environment.

The technology behind Essenzapura air fresheners is based on a mechanical principle that divides substances into microscopic particles and carries them on an air current. Once the particles are released, they disperse into the air, covering a wide area. Unlike hot air nebulization methods, this technology does not use any electronic components and does not require the use of water vapor. Furthermore, cold air is cleaner and free of impurities that can diminish the quality of the nebulization.

The two most important differences are: the cold vapor of ultrasonic diffusers is mainly water, therefore very heavy. In fact, after a certain period of activity, the area surrounding the diffuser remains wet or at least damp, with possible damage to furniture. Essenzapura diffusers, on the other hand, vaporize only pure oils without water. The second substantial difference is in the duration of the scenting. The water vapor from ultrasonic diffusers, being very heavy, tends to fall to the ground immediately. So the scent is only perceptible as long as the device is running. Diffusers with CSAT technology, on the other hand, produce such tiny particles that they remain suspended for hours even after the device is turned off.

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