Expert opinion · Dental hygiene
“Your toothbrush reinfects you
every single day.”
“You can brush perfectly and still put millions of bacteria straight back into your mouth. Sterilizing your brush with UV-C light between uses closes the hygiene gap most people never think about — and it's the easiest upgrade you can make.”

The problem nobody talks about
A single toothbrush holds up to 100 million germs.
Your bathroom is the most bacteria-rich room in your home. Every flush sprays microscopic droplets into the air — and they land right on your bristles. E. coli, staph, and mold thrive in that damp, dark head and go straight back into your mouth twice a day.

The technology
Hospital-grade sterilization, engineered for your bathroom.
Four systems working together to keep every brush clinically clean — automatically, the moment you hang it up.
PIR safety sensor
A near-infrared proximity detector instantly shuts off the UV light when you reach in — so it's completely safe around kids and pets.
Solar + USB power
An 1800mAh lithium battery paired with a built-in solar panel keeps it running, with USB charging as backup whenever you need it.
Holds 4 brushes
Fits electric and manual brushes for the whole family, plus a built-in toothpaste squeezer and a hook for razors. One tidy station.
Set it up in 60 seconds
1
Stick it up
Peel the adhesive backing and mount it on any wall or tile — no drilling, fully removable.
2
Hang your brushes
Drop in up to 4 brushes. The PIR sensor detects when you step away and arms the cycle.
3
Walk away clean
UV-C runs a 60-second sterilization pass. Come back to a brush that's 99.99% germ-free.
Backed by dental experts
The professionals who keep mouths healthy agree.
"I tell every patient the same thing — you can brush perfectly and still reinfect yourself with a contaminated brush. A UV-C sterilizer like KOAKI is the single easiest upgrade to your oral hygiene. It closes the loop most people don't even know is open."
"The PIR auto-shutoff is what sold me. It's the safety feature most cheap UV gadgets skip."
Dr. Marcus Reed, DMD Periodontist
"Damp bristles are a petri dish. Drying and sterilizing between uses genuinely reduces reinfection risk."
Dr. Aisha Kapoor, BDS Family Dentistry
"Simple, automatic, and it works. I recommend it to families with kids especially."

"I genuinely didn't realize how gross my brush was until I used this. It looks and smells cleaner and my whole family has one spot now. Wish I'd bought it years ago."
Michael T. ✓ Verified
"The solar charging is no gimmick — haven't plugged it in once in two months. Mounted it in five minutes, no tools. Kids think the UV light is cool so they actually put their brushes back."
Sofia G. ✓ Verified
"My dentist actually recommended a UV sterilizer at my last cleaning so I looked it up. This one holds all four of our brushes and the toothpaste squeezer is a surprisingly nice bonus."
James P. ✓ Verified
"Was skeptical about another bathroom gadget but the auto shut-off when you reach in is legit. Feels premium, not cheap plastic. Bought a second one for my parents."

Is the UV-C light safe to have in my bathroom?
Completely. A PIR near-infrared sensor instantly cuts the UV-C light the moment anything comes close. It only sterilizes once you've stepped away, so there's zero exposure to you, kids, or pets.
Does it really kill 99.99% of germs?
Yes. Germicidal UV-C light destroys the DNA of bacteria, viruses and mold so they can't reproduce. A single 60-second cycle after each use keeps your bristles clean — up to a 99.99% sterilizing effect.
Will it fit my electric toothbrush?
It holds up to 4 brushes — electric or manual, adult or kids' sizes. There's also a built-in toothpaste squeezer and a hook for razors.
How is it powered?
An internal 1800mAh lithium battery charges from the built-in solar panel and over USB, so it stays topped up with minimal effort.
How do I install it?
Peel and stick. The strong adhesive backing mounts to any smooth wall or tile in seconds — no drilling — and it's removable and repositionable.
