Shortlisted for product design of the year at Dezeen Awards 2019, LARQ bottle by LARQ cleans itself using UV light, for people troubled by the hygiene of tricky-to-wash reusable water bottles.

The LARQ bottle provides instant water purification in a self-cleaning bottle through an LED technology in its lid that emits UV-C light in the 280-nanometre range. According to LARQ, at this wavelength, the light eradicates almost all harmful and odour-causing bacteria and viruses. The bottle also intelligently activates every 2 hours, basking the water and inner surface of the bottle in purifying UV light. Users can turn on the light manually or set it to automatically activate every two hours in self-cleaning mode.
