LARQ PureVis 2 Self-Cleaning Insulated Water Bottle, Mojave Dune, 34 oz, Rechargeable with Nano-Filter Straw

The LARQ PureVis 2 is a rechargeable smart insulated water bottle that combines UV-C self-cleaning with a replaceable nano filter straw to keep cold water tasting fresh on the go.

This bottle merges three features most people want in a single travel companion: UV-C LED purification for periodic self-cleaning, a dense nano-filter straw that reduces chlorine and many chemical tastes, and double-wall vacuum insulation to keep beverages cold for up to 24 hours. It pairs with the optional LARQ app for hydration tracking, but all core functions work independently without a subscription.

How does the UV-C self-cleaning work and what does it do?

The PureVis system uses a patented UV-C LED inside the cap that runs an automated cleaning cycle every couple of hours to minimize microbial growth on the bottle interior and cap surfaces. This is a chemical-free method that helps keep odors and surface contaminants from building up between washes.

• Auto-clean cycle activates roughly every 2 hours when charged.
• Chemical- and mercury-free UV-C LED technology.
• Designed to reduce microbial residue and common bio-contaminants on contact surfaces.

What does the nano filter straw remove and how long does it last?

The included high-density nano filter straw targets taste and odor compounds and a range of common contaminants like chlorine, certain VOCs and select PFAS compounds, while also improving overall water flavor. Each filter is rated for about 40 gallons of use—typically around two months for daily use—after which it should be replaced for continued performance.

• High-density filtration media for chlorine, VOCs, select PFAS and pharmaceutical traces.
• Single filter capacity roughly 40 gallons (~2 months typical use).
• Filter increases draw resistance slightly due to denser media; removable for direct drinking.

Will it keep drinks cold, and can I use it for sports or travel?

The double-wall vacuum insulated 18/8 stainless steel body keeps beverages cold for up to 24 hours and prevents exterior condensation, making the bottle suitable for gym sessions, hiking, commuting and everyday office use. It’s not intended for hot liquids, and for thicker sports drinks you can remove the filter straw to prevent clogging.

• 24-hour cold retention with no sweat exterior on the desk or in a bag.
• Leakproof design and slip-resistant powder coat finish.
• Removable straw and detachable handle for travel and outdoor convenience.

How do I charge, clean and track hydration with the bottle?

The cap charges via USB-C and one charge typically lasts two to three weeks depending on use. The steel body is dishwasher-safe, while the cap, straw and filter pod should be hand-washed; the bottle can optionally pair with the free LARQ app to log sips via a sensor in the cap.

• USB-C charging; single charge lasts multiple weeks.
• Dishwasher-safe bottle body; hand-wash the cap, straw and filter pod.
• Optional app tracking with no subscription; sensor registers sips when bottle sits level.

Who is this for? The LARQ PureVis 2 suits commuters, travelers, outdoor enthusiasts and anyone who wants a low-maintenance, reusable bottle that improves taste and reduces common chemical and biological residues without chemicals. It’s a good match for people who prefer cold beverages all day, value a removable filter straw for on-the-go filtration, and appreciate a rechargeable, app-compatible bottle but don’t require continuous connectivity. The product includes premium stainless steel construction, BPA-free components, and a one-year warranty for everyday use.
