This diffuser is easy to use and works quickly to enjoy. I've been using it constantly since it arrived and I took it out of the box! It helps keep the bedroom hydrated and smelling good.
Great Diffuser

I have purchased several diffusers from different companies and this one is my favorite. Easy to use, runs very quietly and does a good job.

GuardianAir Ultrasonic Diffuser

Incorporate essential oils into your everyday routine. This ultrasonic diffuser uses micro-vibrations to create a fragrant mist infused with your favorite oils. Adjustable mist intensity and light settings makes this diffuser a stand-out at home where it helps you dial in on creating your own perfectly refreshing spa-like moment.


SpaRoom founder Les Wagenheim helped introduce the first reed diffuser in the U.S. back in the 1990s. Les now focuses on incorporating essential oils into our everyday lives.

The small but mighty oils can help give any day a spa-like feel and help you relax or feel invigorated, depending on the feeling you’re looking for. SpaRoom has a method to deliver them just about anywhere.

Their filter-free humidifier is an innovation in its field. It’s the first of its kind to let you add your favorite oils directly into the water reservoir while it works to thwart dryness in your space. If you’re looking to diffuse oils, they’ve got you covered there, too, with a design that works in rooms up to about 300 feet and has adjustable mist and light levels to set the just-right scene. You can also target tighter spots with a USB-powered desktop diffuser. Want to create an aromatherapy experience during your commute? The car vent diffuser lets you take your favorite oils on the go. more Their Story
