Find answers to our most common questions from our list below:

Are Your Diffusers Made With Hospital Grade Plastic?

No, our diffusers are made with medical grade plastics.

Can I Use Citrus Oils With Your Diffusers?

Yes, we use polypropylene plastic which is safe to use with any essential oil, including citrus. However, if using citrus oil, make sure to clean out your diffuser after each use.  Also, use caution with heavy bodied oils as they may sink to the bottom of the water chamber and clog the diffusing disk.

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-particals 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.

Sparoom 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.

I Threw Away My Instruction Manual. Where Can I Get Another?

If you no longer have your instruction manual, you can find it listed on the Instruction Manuals page or the individual product page. Go to the product page for your diffuser. Below the product description, click on the link that says “Download instructions for _____”.

What Type of Oil Can I Use In My Diffuser?

Almost all of our Sparoom Essential Oils are 100% Pure, with the exception of a 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!

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.

When And How Do I Clean My Diffuser?

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 highly 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.

Does My Absorbing Pad Need To Be Replaced? How Often?

The lifespan of a refill pad is roughly 3 weeks. 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 replacment pads at the location where you purchased your diffuser or on our Refills & Maintenance Page.
