The MIST Ultrasonic Capsule utilizes high-frequency sound waves between 42,000Hz and 47,000Hz to create millions of microscopic cleansing bubbles. These bubbles gently implode upon contact with your appliance, lifting away 99.9% of bacteria, plaque, and stains without causing abrasive damage.

Our specially formulated MIST Mint Tablets work in perfect synergy with the ultrasonic waves. While the technology cleanses, the tablet chemically sanitizes, eliminates deep-seated odors, and leaves a crisp, premium mint finish.

For optimal oral hygiene, we recommend running a 5-minute cycle once every morning before inserting your appliance, and once every evening after removing it.

At the wrong frequency, yes. Some cheaper ultrasonic devices operate above 60 kHz — a level that can cause warping, surface micro-damage, or deformation to certain retainer and aligner plastics over time. This is why frequency calibration matters as much as the cleaning itself.

MIST is calibrated to 42–47 kHz — the range used in professional dental clinics and independently verified as safe for daily use on all standard retainer, aligner, and mouth guard materials. Not all ultrasonic cleaners are equal. Frequency is the difference.

Most ultrasonic cleaners on the market are designed for jewellery, watches, or industrial parts — not for dental appliances that sit in your mouth every day. MIST is specifically engineered for oral care: a precisely calibrated 42–47 kHz frequency, 4 UV-C sterilisation lights that eliminate up to 99.9% of bacteria, and a formula-matched cleaning tablet free from SLS, persulfates and sodium benzoate. Everything is designed to work together — safely, every day.

Yes. MIST is designed for daily use. The 42–47 kHz frequency range is clinically recommended for safe repeated cleaning of retainers and aligners without causing material degradation. The 5-minute standard mode is ideal for daily cleaning; the 10-minute intensive mode is recommended for deeper weekly cleaning or for appliances that haven't been cleaned in a while.

MIST is compatible with clear aligners (Invisalign and all major brands), retainers (Hawley, Essix, and bonded), night guards, mouth guards, dentures, orthodontic appliances, and small jewellery items. If it fits inside the Capsule, MIST can clean it.

Water alone activates the ultrasonic waves but cannot dissolve mineral deposits, tackle discolouration, or neutralise odour-causing bacteria. MIST Tablets are formulated specifically for ultrasonic cleaning — they work in sync with the 42–47 kHz frequency to amplify cleaning action and leave zero residue. For best results, always use one tablet per cleaning cycle.

Yes. The MIST Ultrasonic Capsule holds both UKCA and CE certification, covering electromagnetic compatibility (EMC) and electrical safety (LVD) — independently tested and issued by HUAK Certification Laboratory in April 2026. You can view all certificates at mistrituals.com/pages/certificates.
