I originally bought this diffuser for my meditation corner buuut it’s earned a permanent spot on my nightstand. The mist is cool and refreshing and i adore that i can pick different light colors depending on the vibes. Some nights i just use it as a nightlight, other nights i put in essential oils to help me wind down. My little spa thing lmao.
Olivia
I got this as a birthday present from my sister & i didn’t even know i needed a diffuser until I started using it! Now i turn it on every day while i get ready in the morning loving to switch between energizing citrus oils for a fresh start and lavender for winding down at night. I gotta point out that the design is super sleek so it doesn’t look out of place in my living room. If you’re looking for a thoughtful stylish gift, this is it!!!
Aaron
I live in a tiny studio, and let’s just say it can start smelling unpleasant fast ESPECIALLY after cooking or having guests over. Candles never did much so i tried this diffuser with some citrus essential oils and holy smokes. Within minutes my whole apartment smelled fresh and clean and the scent felt natural. I also just love that it doubles as a humidifier because my skin gets super dry in the winter.

My apartment smells superb
I used to burn candles nonstop to get rid of that stale air smell but this diffuser does it better AND i don’t have to worry about forgetting to blow it out. I add a few drops of citrus oil in the morning and my whole place smells fresh all day. Nice 👍

Doesn’t make the air too wet
Since i tried several, i can tell you that some diffusers make everything around them damp but this one puts out the perfect amount of mist. I noticed no wet counters or weird puddles so far. just the right level!

Stress? don’t know her
No idea what kind of magic happens when this thing starts misting but the second i turn it on my whole body just chills. Been using it with lavender & chamomile oils before bed and i’ve never slept better. It’s literally my new nightly ritual, i refuse to sleep without it now!

Doesn’t make annoying water noises
I had another diffuser that made a weird bubbling sound all night like i was sleeping next to a fish tank. I heard Clairu is quiet but didn’t expect it to be this SILENT. Just misting away without disturbing my sleep, so i finally found one that lets me enjoy my aromatherapy without the extra sound effects

Soothing my headache INSTANTLY
Whenever i get migraines i just wanna lay in a dark room and be left alone but sometimes the pain still won’t let up. My mother in law told me to try peppermint oil in a diffuser and omg WHY did i not do this sooner?? it’s like a cooling mist for my brain. It doesn’t make my headache go away entirely but it absolutely helps more than regular painkillers

Wellness starts with your environment. My personal favorite, Clairu, offers exactly that: it creates a calm, balanced space. I’ve been using it in my evening routine, and it helps me unwind without fail. It’s quiet, effortless, and actually fills the room with scent. I now recommend it to my clients looking for a simple way to reduce stress and create a soothing home atmosphere.

Frequently Asked Questions
How do I set up and operate the Clairu diffuser?
Fill the tank with water, add a few drops of your favorite essential oil if you want Clairu to add fragrance to your room. Next, plug it in with the USB/Type-C cable, choose your mist and light settings.
How many drops of essential oil should I add to the water?
The number of drops depends on your preference and room size. A good rule is 3-5 drops per 3.4 oz of water. For the Clairu Diffuser’s 17.6 oz tank, start with 15-25 drops and adjust to your liking.
Can I use any type of essential oil with this diffuser?
Yes, the Clairu diffuser is compatible with all pure essential oils. However, best use high-quality, 100% pure essential oils without additives to maintain the diffuser’s performance and longevity.
How do I clean and maintain the Clairu diffuser?
Keep your diffuser running smoothly with regular cleaning. After each use, empty the water and wipe the tank with a damp cloth. Use a water-vinegar mix to remove residue without harsh chemicals for a deeper clean.
Is it safe to leave the diffuser on while sleeping?
Yes, Clairu has 2h, 4h, and 6h timer settings, so you can set it and relax. Plus, its whisper-quiet operation won’t disrupt your sleep.
Why is my diffuser not producing mist?
If your diffuser isn’t misting, check for common issues like cold water, an overfilled tank, or buildup on the ultrasonic plate. For the best results, use lukewarm water, don’t overfill, and keep it clean.
Is the Clairu diffuser safe to use around pets and children?
The diffuser is safe, but some essential oils can be harmful to pets or kids. Always check which oils are safe before using them in shared spaces.
