Ultrasonic Essential Oil DiffusersWe all know there is no better way to enjoy Aromatherapy than by diffusing Essential Oils. We also know that there is nothing more stressful than purchasing a gorgeous new diffuser and not receiving that healthy, soothing mist you expected.

Whether it be a small USB diffuser or a large unit with a 40-hour run time, each one of our ultrasonic diffusers is designed, built and tested for maximum mist output while ensuring ease of use.

Here are our Our Best Essential Oil Diffuser Tips to help you get the most out of your essential oil diffuser:

What Type of Water Do I Put In My Diffuser?

For all of our SpaRoom Ultrasonic Diffusers, we recommend using tap or bottled water. Water temperature can have an effect on mist output, too! Warmer water tends to create a fuller mist while cold water can inhibit ultrasonic vibrations, therefore producing less mist.

What Type of Oil Can I Use In My Diffuser?

Almost all of our SpaRoom Essential Oils are 100% Pure, with the exception of only a few of our blends. Other companies offer cheap, misleading Oils that may be 100% Natural, but consist of mostly Carrier Oils. Carrier Oils are meant to be applied topically, not diffused. Their thick consistency can actually ruin your diffuser—not just SpaRoom products, but other diffusers too. Most importantly, do not ever use Fragrance Oils in our diffusers. Find out more about different types of Oils here.

Once you have decided on an essential oil to diffuse, refer to your SpaRoom Instruction Manual to see how many drops is recommended for your unit. Adding too much or too little oil can impact mist output!

Do I add Water or Essential Oil First?

All Sparoom Ultrasonic Diffusers are designed to first be filled with water and then Essential Oil.

As we know, water and oil do not mix. But, since the "mist" is created through ultrasonic vibrations, the water is broken down into micro-particles which allows the Essential Oil to attach to it and be transmitted into the air. Adding oil before water can cause the oil to stay in the bottom of the water tank and hinder the ceramic disc's performance of creating ultrasonic vibrations that are responsible for producing mist.

How Much Water Do I Add To My Diffuser?

Ultrasonic diffusers are most effective, last the longest and output the most mist when filled properly. Every diffuser is different and detailed instructions are included in each package, but as a guideline, we currently have five (5) different ways of indicating the Max Fill Line on our diffusers. Never overfill a diffuser with water by exceeding its Max Fill Line.

Do I Need To Clean My Diffuser?

Whether you use your diffuser every day or once a month, maintenance is recommended to keep it operating at it’s best. Check out our blog post on the proper way to clean your diffuser and to make things even easier, check out Klenzor.

I Still Feel My Diffuser Isn’t Producing Enough Mist… What Now?

Make sure it is on a hard, flat surface. You will notice that each diffuser has an air intake on the bottom of the unit. Make sure there is nothing blocking air from entering—if the flow of air is poor, so will be the mist output.

In addition, there is an air output vent on each diffuser that may be inside or on the side of the water tank. Do not ever let water enter through here as this can cause permanent damage to the diffuser—review your instruction manual to help you identify it’s location. If water does get into the air outlet, pour all water out of the water tank, remove the power cord and allow the diffuser to dry for 2-3 days.

Lastly, double check that the water tank lid and diffuser cover are aligned and securely in place.

If you still feel that your diffuser is not meeting your expectations, review your diffuser instruction manualcontact us or review our return policy. Your full enjoyment of our products is our #1 priority!
