LARQ PureVis 2 Self-Cleaning Insulated Water Bottle, Mojave Dune, 23 oz, UV-C Purification and Filter Straw

The LARQ PureVis 2 is a smart, insulated 23 oz stainless steel bottle that uses UV-C light plus an optional nano-filter straw to reduce bio-contaminants and improve taste while tracking hydration via the LARQ app.

Designed for everyday use and travel, the PureVis 2 pairs active UV-C purification with a convenient filter straw and Bluetooth-enabled hydration tracking. Its double-wall vacuum insulation preserves cold drinks for long stretches, and a USB-C rechargeable battery powers the bottle’s self-cleaning cycles. The Mojave Dune finish gives a muted, modern look suitable for gym bags, desks, and backpacks.

How does the PureVis 2 keep water and the bottle clean?

The bottle employs a built-in PureVis UV-C LED in the cap that automatically activates at regular intervals to reduce microbial load on the interior surfaces and in the water. This light works without chemicals and runs on the bottle’s rechargeable battery, so maintenance is largely passive.

• Automatic UV-C cycles every two hours for ongoing sanitation.
• Internal LED targets microbial DNA to disrupt growth.
• Cap electronics remain separate from the stainless interior for easy cleaning.

What does the nano-filter straw do and when should I use it?

The included straw contains a compact filtration media that reduces chlorine, volatile organic compounds, and off-odors to give water a cleaner taste. It’s optimized for smooth flow so you can drink quickly without heavy suction, and it’s ideal when tap water quality or flavor is a concern.

• Improves taste by removing chlorine and common contaminants.
• Designed for effortless sipping — good for workouts and commutes.
• Filter lifespan: roughly 40 gallons or about two months of typical use.

How does the bottle perform for temperature retention and daily use?

Constructed with 18/8 stainless steel and double-wall vacuum insulation, the PureVis 2 keeps beverages cold for extended periods, making it practical for long outings or desk use. The bottle functions normally without the filter straw installed, though LARQ advises against using sparkling or hot drinks to preserve the internal UV and filtration components.

• Cold retention up to 24 hours under typical conditions.
• Fits most cup holders and features a detachable carry handle.
• Stainless interior is dishwasher-safe; cap requires hand washing.

How does the smart app and charging system work?

Pair the bottle with the free LARQ App to monitor water intake, set hydration goals, and receive reminders; the bottle’s sensor logs use automatically when resting upright. A USB-C port lets you recharge quickly, and a single charge can support about a month of regular purification cycles.

• Real-time intake tracking and personalized reminders via Bluetooth.
• USB-C fast charging, long battery life per charge cycle.
• Detachable handle and lightweight design for everyday portability.

Who is this for? The PureVis 2 is suited to active commuters, travelers, gym-goers, and anyone who values cleaner-tasting water with minimal upkeep and wants hydration tracked automatically. It’s a practical step up from ordinary reusable bottles when you want UV sanitation, optional taste filtration, insulation for cold drinks, and app-based accountability in a single, durable package.
