Stainless Steel Alkaline Portable Flask

A stainless-steel portable flask with built-in alkaline filter media for fresh alkaline water on the go. Fill from any tap and let the flask raise pH while reducing chlorine and trace metals. A travel-friendly upgrade for anyone who drinks alkaline water at home.

$69.99

The flask uses a 13-mineral filter including tourmaline, zeolite, and maifanshi stone. As water moves through the filter, far infrared rays and negative ions help restructure ordinary water into alkaline 'nano water' with smaller molecular clusters — designed for easier absorption and improved pH balance.

  • Helps reduce heavy metals, chlorine, free radicals, and toxins
  • Micro-clusters water molecules for faster absorption at the cellular level
  • Lowers ORP by 200+ mV — antioxidant-rich water
  • Enriches water with calcium, magnesium, potassium, and negative ions
  • Durable, BPA-free 304 stainless steel — portable for travel and workouts
  • pH increase — typically +2 points (to 7–9.5)
  • ORP reduction — at least -200 mV
  • Filter life — approximately 3 months with daily use (1L/day)
  • Material — Food-grade 304 stainless steel (BPA-free)
  • Minerals — 13-mineral filter (tourmaline, zeolite, maifanshi stone, others)

How often should I replace the filter?

Approximately every 3 months with daily use of 1 liter per day.

What pH should I expect?

Typically a +2 increase, taking water to pH 7–9.5 depending on input.

Why do I see bubbles?

Visible hydrogen bubbles during activation are normal — they indicate the filter is working.
