The LARQ PureVis Bottle is the world's first self-cleaning water bottle and water purification system. Free from chemicals, mercury and ozone, the bottle uses the same technology that is used in hospitals for sterilisation. Powerful PureVis UV-C LED technology activates at the touch of a button and every 2 hours to eliminate harmful bacteria and viruses, proving 10,000x more hygienic than regular reusable bottles. It’s also fully rechargeable, with the battery lasting for up to 1 month. But that's not all, as double-wall vacuum insulation helps keep your water cold for 24 hours or hot for 12, meaning your water will always be poured at the right tempertaure, and fresh to the taste.
