This is a little powerhouse!
This is my first diffuser and I love it! Never overpowering, it emits the perfect amount of aroma. I simply plug the USB cord into a charging block (which is plugged into a standard outlet) and it’s perfect for my close kitchen/DR area. I was surprised it runs cool, too. I highly recommend this little powerhouse!

It was delivered fast. It works very well. Only thing is there’s an open/close toggle inside that doesn’t say anything about it in the instructions what or how it should be used.

Great Product
I wasn't sure about a diffuser powered by usb, water and electronics and all that, but this little thing works great! It's placed in a dense electronics area and, so far, no problems. The smell is truly noticeable in a (roughly) 15 x 20 room....and the colors are pretty! :)

great little diffuser
The small size of this diffuser is perfect for my home office and for our small living room. One or two drops of oil is sufficient for our needs. For the first use, I shook the oil bottle a bit too rigorously and 5 drops came out, which was definitely too much. The oil clogged up what I think is the air intake (see photos) and so the diffuser wasn't working correctly. Unfortunately, this little intake is not described at all in the instructions. There is a small cover inside the diffuser in the bottom (so water sits on it) that has arrows on it for open in one direction and close in the other. I'm not really sure what it opens and closes for other than to clean it out (oil does tend to collect there at times). I run the diffuser with it in the closed position.

There is a small opening in the bottom of the diffuser, with 'open' / 'closed' arrows. What is this for, and which position should it be in?
BEST ANSWER: Great question! It should be in the closed position. You may remove it to be able to clean the metal plate below, if you choose to do so we advise using extreme caution and care to not damage the plate.
Thanks!

Can I use the non-neat oil blends in this diffuser or do I need to use the neat versions of oils that do not have the carrier oils in them?

Droplet Diffuser


BEST ANSWER: Many of the blends are still able to be diffused, FCO is a thin carrier oil that does not cause an issue when diffusing. There are however some blends or oils that are too thick to diffuse such as Vetiver.
We recommend only diffusing the oils with a diffusion icon on the label.

I’m completely new to essential oils. How should I use this? Do I add the water then put in my oil? I’ve checked and my oil can be diffused. If so any suggestion for how many drops to use? Do I use the carrier oil I purchased ( FCO) and add the essential oils to that instead of water? Thank you.
BEST ANSWER: Great question! You will fill the diffuser with water to the fill line marked inside. You may add 5-10 drops of essential oils to the water depending on personal preference. You do not need to dilute the oils before adding them to water.
Thanks!

Can this be used as a humidifier?
BEST ANSWER: Hello Nicole:
The droplet diffuser does expel a small amount of mist into the air, but not enough to be classified as a humdifier.

There is a plastic round piece that comes with the diffuser but the instructions don’t say what to do with it? It’s probably obvious but I want to make sure I put it together right before starting to diffuse the oils. Thanks so much for your help!
BEST ANSWER: Hello Cristina!
This piece is so you can access the plate for cleaning. However it is fragile and does not need to be removed for a regular cleaning. Be sure to keep it in the closed setting to prevent debris getting to the plate.
Thanks!

It is very simple! You may either rinse off the water from the diffuser and wipe off the essential oil residue or you may diffuse our Klenzor Diffuser Cleansing Tablets in the diffuser and it will clean itself! Wiping off the entire diffuser does not take longer than 5-10 minutes.
