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 another heat source to warm water in which essential oils are dispersed, which means risking the loss of therapeutic benefits or distorting the essences, as heat can damage volatile compounds. Diffusion by natural evaporation, 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 in. Ultrasonic diffusers are the most common and use water to disperse fragrances. Essenzapura atomizer diffusers instead use CSAT cold air technology without water. Let's look at the important differences between the two.

Both ultrasonic and CSAT cold air diffusers use a heat-free medium to disperse scent, preserving the delicate compounds in essential oils and purifying the air. However, the method in which they do so 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 aromatic 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, resulting in a subtle and consistently scented environment.
The technology behind Essenzapura scenters is based on a mechanical principle that divides substances into microscopic particles and carries them on a current of air. Once the particles are released, they disperse into the air, covering a large area. Unlike hot air nebulization methods, this technology does not use any electronic heating components and does not require the use of water vapor. Furthermore, cold air is cleaner and free of impurities that can decrease the quality of the nebulization.
There are two most important differences: the cold vapor of ultrasonic diffusers consists mainly of water, therefore very heavy. In fact, after a certain amount of time, the area surrounding the diffuser remains wet or at least damp, with possible damage to furniture. Essenzapura diffusers instead vaporize only pure oils without water. The second substantial difference is in the duration of the scent. The water vapor of ultrasonic diffusers, being very heavy, tends to fall to the ground immediately. Therefore, the scent is perceivable only as long as the device is running. CSAT technology diffusers, on the other hand, produce particles so tiny that they remain suspended for hours even after turning off the device.
For these reasons, CSAT cold air diffusers have become the preferred means for diffusing scents in many homes and workplaces.
