What is an Ultrasonic Diffuser and How Does One Work?

It’s actually really interesting how ultrasonic diffusers work.

If you’ve ever used one before, you know that you have to fill it with water, then you add your essential oils. The two don’t necessarily mix—in fact, the essential oils will sit on top of the water. The next step is to get those oils out and about into the air, and this is the part that most people mistakenly think of as steam.

There is, in fact, no steam involved with an ultrasonic diffuser (steam would require the water to be heated up, which it isn’t). There’s a small disc or plate beneath the water which causes ultrasonic vibrations. This “agitates” the water, enough so that it, and the essential oils, gets broken down into their base molecules. A fine mist is produced, thus diffusing the oils into the air.

Ultrasonic diffusers have a lot of benefits. They don’t require much power, they’re easy to clean, and they double as a humidifier. That last bit could be seen as a pro or a con, depending on how you feel about humidity—but we find that most of our customers who were unsure end up loving the extra moisture in the air (since it can alleviate dryness of the skin, eyes, and nasal passages).

As a final note, ultrasonic diffusers are also very budget-friendly. The units themselves tend to cost less than nebulizing diffusers on average, but more importantly, ultrasonic diffusers use much less oil than nebulizing diffusers. They also run for longer periods of time, in several cases up to 24 hours before needing to be refilled.
