Depending on the motor or fan strength of your diffuser, some noise is normal during operation. It is also common to hear the water moving inside your unit.

If the unit is making a noise that sounds abnormal, please discontinue use and contact our Customer Care Team.

Make sure it is properly plugged in. If it’s plugged in, and the lights nor mist will turn on, make sure there is power coming from your source.

A possible cause may be mineral or oil buildup, causing the unit to have difficulty misting.

Please proceed with cleaning your diffuser with Klenzor™.

If the diffuser is not misting very strongly, there are a few things that can cause this.

Check your water level. If the water is too full, the mist will not come out strongly. We recommend filling the water slightly below the max fill line.Make sure the unit is sitting on a hard, flat surface. Do not place it on something soft, like a towel that could absorb theultrasonicvibrations.Make sure the unit is not sitting directly under an air vent orfanthat may be dispersing the mist.

Some storage tips would be to keep the pad in an air tight container or baggie when not in use. You'll notice the pad becoming very saturated and no longer able to hold oil, that will be an indication to change the pad. You should be able to purchase replacement pads at the location where you purchased your diffuser or on our Accessories Page.

We recommend cleaning your diffuser frequently, especially when you change your selection of essential oils. Regular cleaning is important to maintain the life of your unit. To avoid buildup, please do not let water or oil inside the unit when not in use. Over time, water, mineral or oil buildup on the vibrating disk can decrease the effectiveness of your ultrasonic diffuser. We only recommend Klenzor, our diffuser cleansing tablets, which quickly and easily free your diffuser of any buildup and mineral deposits.

If you do not have any Klenzor on hand, a good way to remove possible buildup is to mix ¼ cup of white vinegar with warm water. Let it soak inside the water well for 3 hours. Do not turn the unit on while soaking. After 3 hours, dump out the water and use a cotton swab to gently wipe away any loose buildup from the vibrating disk. Do not push hard on the disk. Rinse the unit out and fill with clean cool water. Plug the unit back in and begin misting.

For all of ourSpaRoom Essential Oil 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.

Almost all of our SpaRoom Essential Oils are 100% Pure, with the exception of 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 are recommended for your unit. Adding too much or too little oil can impact mist output!

If you no longer have your instruction manual, you can find it listed on our Instruction Manuals page.

SpaRoom Ultrasonic diffusers are most effective, last the longest and output the most mist when filled properly. Everydiffuseris 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.

We sell manydiffusersand they all have different functions. Please refer to yourinstruction manualfor specific directions on how to use yours properly.

To extend the life of your ultrasonic diffuser, please be certain to use only 100% Pure Essential Oils. By doing so, it will ensure your unit qualifies for any future Warranty Claims. Any use of Fragrance Oils will void our warranty due to the synthetic ingredients used. We included the information below, to help with the maintenance of your diffuser.

We recommend cleaning your ultrasonic diffuser frequently, especially when you change the selection of your oils. Regular cleaning is important to maintaining the life of your unit. To avoid buildup, please do not let water or oil sit inside the unit when not in use. Over time, mineral deposits and/or oil residue can build up on the vibrating disk, requiring the unit to be cleaned with Klenzor™.

KLENZOR™ is our dissolving cleaning tablet, suitable for all ultrasonic differs, which is EPA approved and bio-degradable. To clean, place one dissolving Klenzor™ tablet into the water well of your ultrasonic diffuser. Turn the diffuser on and run for a 2-hour cycle, allowing the tablet to dissolve and eliminate any buildup that may impair its performance or fragrance output. After the cleaning, pour out the contents, being certain to avoid water getting into the air vent opening at the top of the water well. Once emptied, use a cotton swab to gently wipe away any loose buildup from the vibrating disk. Regular use of Klenzor™ can extend the life of your unit. We suggest following our recommended cleaning frequency listed below.

Everyday use - Clean Weekly

Few times a week use - Clean Weekly

Couple times a month use - Clean Monthly

All SpaRoom Essential Oil Diffusers are designed to first be filled with water first 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 discs performance of creating ultrasonic vibrations that are responsible for producing mist.

Yes, we use polypropylene plastic which is safe to use with anyessential oil, including citrus. However, if using citrus oil, make sure to clean out yourdiffuserafter each use. Also, use caution with heavy bodied oils as they may sink to the bottom of the water chamber and clog thediffusingdisk.
