LARQ does water a different way. LARQ Bottles self-clean and purify water with just the push of a button. That means you get pure, clean water on demand - and never have to worry about that funky smell. With one of these water bottles, you know that every drink will be healthy thanks to the built-in purification system in each. It’s all done with digital technology that relies on UV-C LED to get rid of harmful viruses and bacteria — up to 99.99%! The bottle intelligently turns on every 2 hours to purify both the water you put inside as well as the inside of the bottle. The UV-C light eradicates biological contaminants by destroying their DNA. That’s not all LARQ has managed to incorporate into this sleek design, though. The double-wall insulation in their original bottle can keep your water hot or cold for hours.
