LARQ Brand Guidelines: The Self-Cleaning Bottle, PureVis UV-C & Clean Design

LARQ put a UV light in the cap.

LARQ is a lesson in building a brand on one piece of technology. It was founded in 2017 by Justin Wang in San Francisco, and shipped its first product — the original LARQ Bottle — in October 2018. The idea is elegantly simple: a UV-C LED in the cap (its PureVis technology) that periodically activates to reduce odour-causing bacteria in the water and on the bottle’s interior. LARQ positions it as “the world’s first self-cleaning water bottle.” (Two honest notes: “world’s first” is LARQ’s own positioning, best attributed; and no official brand hex or typeface is published.)

The self-cleaning claim is the whole hook. LARQ publishes organism-specific, lab-tested figures — for example, eliminating up to 99.99% of E. coli and up to 99.999% of Salmonella under lab conditions — which are best quoted precisely and attributed to LARQ’s testing. One important clarification for honesty: the UV-C is designed to keep already-potable water and the bottle fresh and reduce odour, not to purify questionable or backcountry water — so it’s not a medical-grade steriliser. The line later extended to the LARQ Pitcher PureVis (2020), which pairs the UV with a Nano Zero filter (filtration, distinct from the UV self-cleaning of the bottle).

LARQ leaned into design and visibility. It was a CES 2019 Innovation Award Honoree (Sustainability & Eco-Design), and it appeared on Shark Tank (Season 12), where founder Justin Wang pitched the self-cleaning bottle. The product is premium (the PureVis 2 bottle around $129) and colourful — modern, minimalist bottles in rotating collection colours like Monaco Blue, Obsidian Black and Granite White. It’s privately held and venture-backed (a ~$11M Series A in 2020), and has been reportedly acquired by Brita around 2024 (a single-source report, so best hedged). A light in the cap.

LARQ’s identity reads as clean, modern and colourful — blues, mints and a crisp obsidian/white, with a rotating range of collection colours. The palette feels fresh, tech-forward and health-minded, fitting a brand whose whole promise is clean — clean water, a clean bottle, a clean look. It’s bright and contemporary rather than rugged or ornate, signalling wellness and modern technology. The colour names rotate by season, so the palette is expressive and flexible rather than fixed. The honest caveat: LARQ publishes no official brand hex, so the blue and mint here are an original, unofficial interpretation of its collections, not first-party values.

The lesson is a clean, modern palette can embody a “clean” promise. LARQ’s blue-and-mint world literally looks like the freshness it sells. For designers, it’s a reminder that colour can reinforce a core benefit — a self-cleaning product should feel clean. The takeaways: match the palette to the core promise (fresh, clean, modern); keep colour collection-based and flexible; and treat specific hexes as unofficial when the palette rotates by season.

The wordmark is a precise, modern tech sans — clean and engineered.

LARQ’s identity carries a precise, modern, tech spirit — a clean sans-serif wordmark whose even, engineered letterforms read as contemporary, health-minded and technical. The restrained type matches a brand built on a genuine piece of technology (UV-C self-cleaning) and a wellness promise, and it keeps the focus on the clean, modern product. Set against a fresh blue-and-mint palette, the type feels engineered yet approachable — exactly the clean-tech, wellness personality LARQ cultivates. It’s precise and modern rather than decorative, mirroring the minimalist bottle. Because the exact wordmark face isn’t publicly documented, the honest description is “a precise tech sans spirit,” not a named font. The type behaves like the brand: clean, modern and engineered.

LARQ sold a bottle on its tech.

LARQ is a lesson in making a single technology the whole brand. Most premium bottles compete on colour, insulation or fashion; LARQ competed on a genuinely novel function — a UV-C light that keeps your water and bottle fresh — and built the entire brand identity around that one idea. That focus is powerful: it’s a clear, demonstrable, patentable differentiator that instantly answers “why is this bottle $130?” and gives the brand a wellness story (clean water, less odour, fewer disposables) that resonates with a health-minded audience. The visibility play (a CES honor, a Shark Tank appearance) amplified a product that’s easy to explain in one sentence. The honest discipline is in the claims — LARQ publishes specific, attributed lab figures and positions the tech for already-potable water, not as a medical steriliser. It’s proof that a single, real technological benefit — clearly named, honestly claimed, and made the hero — can anchor a premium brand. Lead with the tech, and the bottle follows.

For designers and brand-builders, LARQ offers a clear takeaway: a single, genuine technology can be the whole brand. The lessons: make one real, demonstrable innovation the hero (PureVis UV-C self-cleaning); justify a premium with a clear benefit and honest, specific claims; and use design and visibility to make it legible (clean look, CES, Shark Tank). It’s also a reminder to keep the facts precise — LARQ was founded in 2017 by Justin Wang, shipped its first self-cleaning bottle in 2018, appeared on Shark Tank, and reserves its UV-C for already-potable water. LARQ sold a bottle on its tech — proof that one real technology can anchor a brand.
