Hold the cap and a 180-second deep-clean cycle eliminates 99.9% of bacteria and viruses — in the water and on the inner walls. No brushes. No smell. Ever.

"The reminder glow is what got me. I went from barely a litre a day to actually hitting my target without thinking about it."
"Used to dread the smell of my old flask. This one just… never smells. The UV thing actually works."
"Kept ice overnight in a heatwave. Battery lasted 8 days on my first charge. Wish I'd bought two."
A UV-C LED in the cap emits light at 260–280nm — the wavelength that destroys the DNA of bacteria and viruses. Hold the cap to trigger a 180-second cycle that purifies the water and the inner walls. It also self-runs every 2 hours to stay fresh.
Yes — the cycle only runs when the cap is sealed on the bottle, so no light escapes. The same technology is used to sterilise hospital equipment and baby products.
