01 — Ultrasonic Technology

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
UV-C Sanitizing
02 — UV-C Light Sanitization

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
USB-C Ready
03 — USB-C Rechargeable

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
04 — Smart Interface

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
2× Cleansing Ports
05 — Dual Cleansing Ports

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
