LARQ PureVis Smart Self-Cleaning Water Bottle — 25 oz Insulated Stainless Steel with UV-C Sanitizing

Combining double-wall vacuum insulation with a patented PureVis UV-C LED cap, this LARQ bottle offers hands-free surface and water sanitation on a schedule, plus all-day temperature retention. It uses short bursts of UV-C light inside the cap to disrupt microbial DNA rather than filters, and the powder-coated stainless-steel body resists sweat and dents. Available in 17 oz and 25 oz sizes, the bottle fits standard cup holders and backpack pockets for everyday use.

How does the self-cleaning UV-C system work?

The PureVis cap contains a UV-C LED that activates every two hours to neutralize microbes on the inner surfaces and in the water. The light is contained inside the bottle—sensors prevent cycling when the cap is open—so the system only operates safely within the bottle. This is an electronic sanitizing method, not a filter, so it targets bacteria and viruses but does not remove dissolved minerals or heavy metals.

• Patented PureVis UV-C LED cycles automatically every 2 hours.
• Light sensor ensures UV only activates when cap is secured and dark inside.
• Sanitizes inner surfaces and standing water; no physical filter required.

How long will a charge last and how do I recharge it?

The bottle cap’s Li-polymer battery can power typical use for up to about a month between charges, depending on cycling frequency. Recharging takes roughly one hour using the included micro-USB cable; only the cap needs charging. The cap is splash-proof (IPX7) but should never be submerged or placed in the dishwasher because it contains the electronics.

• Approximately one hour to fully recharge the cap.
• Up to a month of typical use per charge; indicator light warns when low.
• Micro-USB cable included; cap is splash-proof but not submersible.

What temperature performance and daily conveniences does it offer?

The double-wall vacuum-insulated stainless-steel body keeps beverages cold up to 24 hours and hot up to 12 hours under normal conditions. Its powder-coated no-sweat finish prevents condensation and avoids leaving rings on surfaces, and the bottle shape is designed to fit most car cup holders and backpack side pockets. The wide mouth makes filling, pouring, and adding ice simple.

• 24 hours cold, 12 hours hot in double-wall vacuum insulation.
• No-sweat powder coat finish keeps hands and surfaces dry.
• Fits common cup holders and backpack pockets; wide mouth for easy fill.

Who is this for? The LARQ PureVis Smart Bottle suits commuters, travelers, gym-goers, hikers, and office workers who want temperature retention plus hands-free interior sanitation without disposable filters or daily chemical cleaners. It’s ideal for people who prefer a low-maintenance reusable bottle that fits everyday carry, and for those who travel often and want a single bottle to handle long days, workouts, and short trips. Note: this product sanitizes with UV-C light and does not filter out dissolved metals, minerals, or sediment; the body should be washed with soap and water periodically, and the cap should be charged and kept dry of immersion to maintain electronics and warranty coverage.
