The Larq has helped me eliminate plastic bottles and reduce the undesired consumption of microplastics. The customer service is excellent. I do wish the bottle was lighter and that the cap lasted longer . I now want to know how best to recycle the cap when it 'dies'

Traveled with my PureVis in India for 7 weeks last summer including a week-long hike in the Himalayas, then Japan and China this year, and no tummy issues at all! Had to replace my cap after China, and customer service was really helpful, as it was past the time frame of the warranty.

Just the FAQs

PureVis™ technology uses 270-275 nanometer spectrum to neutralize up to 99% of bacteria such as E.coli by breaking down their DNA before they have a chance to spread, improving the quality of your water. At the minimum, the bottle should be filled with water that is clear to the eyes and does not contain any physical sediment as PureVis™ technology will not remove these impurities from the water. The UV-C LED chip in the LARQ Bottle PureVis™ Cap are smaller, more energy efficient, non-toxic (mercury-free), and more economical compared to traditional Mercury-based UV technology.

The cap is waterproof IPX7-rated, so you are able to hand wash the cap if needed. Please ensure that the cap is completely dry before charging to avoid the risk of injury.

The LARQ Bottle PureVis uses a Li-Polymer battery, similar to the one you would find in your smartphone.
