LARQ PureVis Smart UV-C Insulated Stainless Steel Water Bottle — 24H Cold, Self-Cleaning Cap

The LARQ PureVis is a rechargeable, insulated stainless-steel bottle with an integrated PureVis UV-C LED cap that periodically sanitizes water and inner surfaces to keep your bottle fresher between washes.

The PureVis combines double-wall vacuum insulation and a UV-C LED purification system built into the cap so you can carry cold or hot beverages while reducing bacterial buildup inside the bottle. Designed for everyday use, the LARQ bottle blends a no-sweat powder finish with a light-ring cap that signals purification cycles and battery status. It’s intended as a reusable alternative to single-use bottles and as a low-maintenance travel companion.

How does the self-cleaning UV system work?

The cap’s PureVis UV-C LED emits short bursts of UV-C light that disrupt microorganisms on the interior surfaces and in the water, and it is programmed to run automatically every two hours. A light sensor ensures the cycle only operates with the cap properly seated and the light contained inside the bottle.

• Patented PureVis UV-C LED built into the cap
• Automatically cycles every two hours to reduce bacterial presence
• Light sensor prevents external UV exposure—only activates inside the bottle

Will it keep drinks cold or hot for long periods?

The double-wall vacuum insulation preserves temperature for extended use: up to 24 hours for cold beverages and roughly 12 hours for hot ones. The powder-coated, no-sweat exterior prevents condensation and fits most cup holders and backpack pockets.

• Double-wall vacuum insulated stainless steel
• 24-hour cold retention and about 12-hour hot retention
• Sweat-free powder coat and standard-size base for holders

How do I charge and maintain the bottle?

The cap contains the electronics and a Li-polymer battery; charge it with the included USB cable to restore a month-long charge depending on frequency of use. The cap is splash-resistant but should never be submerged or placed in a dishwasher—clean the metal body with soap and water as needed.

• USB-rechargeable cap with around a month per charge
• Micro USB cable included; full charge in about an hour
• Cap is IPX7 splash-proof but not dishwasher-safe or submersible

What does this bottle not do or remove?

The PureVis system uses UV-C light rather than filtration, so it does not filter out heavy metals, minerals, sediment, or dissolved contaminants. For water with known chemical contamination or particulates, use an appropriate filter or treated water source.

• Not a replacement for filtration—no removal of metals or sediment
• Best used with potable water sources or filtered water
• Manufacturer warranty covers defective parts for one year

Who is this for? The LARQ PureVis bottle is suited to commuters, travelers, outdoor enthusiasts, gym-goers, and anyone who wants an insulated reusable bottle with low-maintenance surface sanitation. It’s a practical choice if you want long temperature retention, a sweat-free exterior, and the convenience of periodic UV cleaning without replacing filters. Choose this bottle if you value portability, rechargeable electronics, and a compact design that fits cup holders and packs comfortably for daily life and light adventure.
