The science behind
a cleaner smile.
Every component of the COJA Cleansing Pod was engineered with one purpose — to give you clinical-grade hygiene in the time it takes to make your morning coffee.
See It In Action
Watch how to set up and use your COJA Cleansing Pod — from first fill to a clinically clean appliance in minutes.
48K Hz ultrasonic
frequency cleaning
The COJA Pod generates 48,000 ultrasonic vibrations per second, creating millions of microscopic bubbles that implode on contact with your appliance. This process — called cavitation — reaches every surface, groove, and crevice that a toothbrush physically cannot.
- Removes 99.9% of plaque, bacteria, and odour-causing buildup
- Penetrates areas invisible to the naked eye
- Gentle enough for delicate plastics, retainer wire, and aligners
- No scrubbing — zero risk of surface scratches
Medical-grade
UV-C elimination
UV-C light at 254nm wavelength is clinically proven to destroy the DNA of bacteria, viruses, and pathogens — rendering them unable to replicate. The COJA Pod's UV-C chamber surrounds your appliance with this germicidal light for a chemical-free, residue-free sanitization.
- Eliminates 99.9% of bacteria, viruses, and mold spores
- Zero chemicals — safe for all dental appliances and plastics
- No heat — won't warp aligners, retainers, or mouthguards
- Odour-neutralizing at a molecular level
Cordless. Portable.
Always ready.
The built-in rechargeable battery charges via standard USB-C — the same cable as your phone. No proprietary connectors, no searching for adapters. Charge once, run multiple cycles. Take it anywhere.
- Universal USB-C charging — works with any modern charger
- Fully cordless operation — no countertop clutter
- Travel-ready — TSA compliant, fits in any toiletry bag
- Extended battery life for days of daily use per charge
LED display.
One-button simplicity.
A crisp LED digital display shows your selected mode and countdown timer in real time. One button cycles through all three cleaning modes. No complicated menus, no guesswork — just press and go.
- LED digital display with real-time countdown timer
- Single-button operation — cycle through modes with one press
- Auto shutoff when cycle completes
- Intuitive enough for any age group
Beyond aligners —
clean everything.
Two dedicated cleansing ports extend the Pod's capability beyond dental appliances. The ultrasonic and UV-C technology works equally well on everyday personal care items — elevating hygiene across your entire routine.
- Port 1 — primary cleansing chamber for aligners, retainers, mouthguards
- Port 2 — secondary port for toothbrush heads, tweezers, razors, jewelry
- Both ports active simultaneously for efficient multi-item cleaning
- Stainless steel 200ml chamber resists staining and odour absorption
A solution for every need.
Quick Cleanse
Ultrasonic + UV-C
The daily go-to. A full ultrasonic cavitation cycle combined with UV-C sanitization — done in 5 minutes. Perfect for your morning or evening routine without slowing you down.
Deep Cleanse
Ultrasonic + UV-C
For a deeper reset. An extended 10-minute ultrasonic cycle with full UV-C sanitization tackles stubborn buildup, discolouration, and heavy bacterial load. Recommended weekly or after illness.
Gentle Cleanse
UV-C Only
UV-C sanitization without ultrasonic vibration — ideal for highly sensitive items, freshly fitted appliances, or items that benefit from gentle sterilization only. No movement, pure germicidal light.
