Just the FAQs

The LARQ Bottle uses patented UV-C technology to purify your water and bottle at the touch of a button. 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.
The UV-C wavelength emitted from the UV-C LED located in the LARQ Bottle Caps are optimized at the 280 nanometer spectrum to eliminate up to 99.9999% of bacteria and viruses by breaking down their DNA before they have a chance to spread, making the water pure and safe to drink. At the minimum, the LARQ Bottle should be filled with water that is clear to the eyes and does not contain any physical sediment as the UV-C LED will not remove these impurities from the water. The UV-C LED chip in the LARQ Bottle are smaller, more energy efficient, non-toxic (mercury-free), and more economical compared to traditional Mercury-based UV technology.
Normal Mode is a 1 minute cleaning cycle and delivers 12 mJ/cm^2 of UVC to the water and the inner surface of the bottle. Tap the button on the cap once to activate the cycle. It’s the right choice for daily use, if your water is from a trustworthy source.
In Adventure Mode, the LARQ Bottle delivers a higher dose of UVC: >30 mJ/cm^2. Activate this 3 minute cycle by double tapping the button on the cap. It’s a good choice if you’re not sure about the quality of your water or you just want extra peace of mind.
