  • DO NOT turn on or operate the ME Bottle cap if not screwed on to the ME Bottle.
  • The ME Bottle cap should only be used with the ME Bottle for complete safety and efficacy. The efficacy of the UV water disinfection has only been tested with the ME Bottle and we cannot guarantee the UV’s effectiveness when used with alternative bottle designs.
  • NEVER tamper with the ME Bottle or ME Bottle cap as the UV-C light assembly is a high voltage device. DO NOT open, expose, modify or touch internal circuitry as this can lead to high voltage shock. Removal or tampering with the electronic circuit board may cause injury or damage to the user or Product, and will void all warranties.
  • To prevent danger or risk of shock, keep and store this Product away from rain or liquid. DO NOT use the charger near water: ie. near a bathtub, wash basin, kitchen sink, laundry tub, or swimming pool.
  • Clean the outside of the Product with a clean, moist cloth. DO NOT use any strong cleaning sprays, fluids, or similar chemicals on the Product.
  • If the ME Bottle cap or any of its components malfunction or fails to perform as expected, cease use immediately. DO NOT open or attempt to repair the ME Bottle cap or its components.

  • DO NOT remove the ME Bottle cap while a disinfection cycle is in progress.
  • To cancel a disinfection cycle, first press and hold the button on top of the cap until the countdown stops.
  • DO NOT use as a light source.
  • DO NOT expose the Product to temperatures below freezing or above 32°C / 90°F.
  • The ME Bottle cap’s UV-C light is not intended to disinfect water on the lip or exterior surfaces of the Bottle where the light does not reach i.e., those that typically come in contact with the mouth when drinking. Be certain that the Bottle and cap have been properly cleaned (accessory brush included to clean the cap’s internal crevices) prior to use.
  • As with any water treatment system, you should always have a backup method available.
  • The included charcoal filter is only intended as an accessory item to improve turbidity and flavor of water and may be reused. However, the charcoal piece/bag within the filter is single-use ONLY. Replace after every use.
  • The charcoal filter system may be used before the ME bottle cap’s disinfection cycle; however, it should NOT solely be used, in replacement of the cap’s disinfection cycle. ALWAYS use the charcoal filter system with the cap’s disinfection cycle.
  • Do not allow impact to the UV-C light. If the cap or UV-C light assembly is cracked, dented or damaged, discontinue use. Contact ME Bottle customer service or visit com for more information regarding proper disposal or recycling.
  • While carefully controlled microbiological laboratory testing has been conducted, the use of the cap’s UV-C light by consumers in the field may produce varied results from laboratory test data.
