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.

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.

  • 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)
  • 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

Stainless Steel Alkaline Portable Flask

Turn ordinary tap water into alkaline, antioxidant-rich hydration anywhere you go. This sleek, food-grade stainless steel flask uses a 13-mineral filter system to boost pH, reduce toxins, and create smooth, great-tasting water that your body absorbs more efficiently.

Key Benefits

  • Cleaner, Safer Water: Reduces heavy metals, chlorine, free radicals, and toxins.

  • Faster Hydration: Micro-clusters water molecules for quick absorption at the cellular level.

  • Antioxidant Power: Lowers ORP (oxidation-reduction potential) by 200+ mV, creating water with measurable anti-aging and immune-supportive benefits.

  • Mineral-Enriched: Tourmaline, zeolite, maifanshi stone, and other minerals infuse water with calcium, magnesium, potassium, and negative ions.

  • Durable & Portable: Made of BPA-free, 304 stainless steel; lightweight and ideal for travel, workouts, or daily use.

How It Works
The mineral filter releases far infrared rays and negative ions, restructuring ordinary water into alkaline “nano water” that hydrates deeply, supports pH balance, and helps combat oxidative stress. Regular use may aid energy, recovery, and overall vitality.

Specifications

  • pH increase: typically +2 points (to 7–9.5)

  • ORP reduction: at least –200 mV

  • Visible hydrogen bubbles during activation

  • Easy to clean; filter lasts ~3 months with daily use (1L/day)

Stay energized, balanced, and refreshed wherever life takes you — with the Stainless Steel Alkaline Portable Flask.

Questions

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.
