The LARQ Bottle uses PureVis UV-C purification technology to neutralize up to 99.9999% of harmful, odor causing bio-contaminants and improve the quality of your water no matter where you are. Self cleaning and worry free, this super portable water bottle intelligently activates every 2 hours or at the push of a button to bask the water and inner surface of the bottle in purifying UV-C light. This mercury-free water sanitization system doesn't rely on any wasteful filters you have to replace constantly.
The UV-C wavelength emitted from the UV-C LED located in the cap is optimized at 280nm to eliminate bio-contaminants such as E. coli— breaking down their DNA before they have a chance to spread. This UV-C LED chip is small, more energy-efficient, and more economical compared to traditional mercury-based UV technology.
Plus it's powered by a USB-rechargeable battery that provides up to 1 month of regular use per charge. When your battery is low, your cap will blink yellow before and after a cleaning cycle to alert you to charge it! PureVis features two modes: Normal Mode is a 1-minute cleaning cycle perfect for daily use if your water is from a trustworthy source. In Adventure Mode, the LARQ Bottle delivers a higher dose of UV-C you can activate by double-tapping the button on the cap.
This 3-minute cycle is a good choice if you’re not sure about the quality of your water or you just want extra peace of mind.
