LARQ does water a different way. 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%! 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 many hours. That’s why once we tried this bottle, we stuck with it.
