Advantages of EXTRA CLEAN Filter System

The 1THE Water Filter System Pro uses advanced hollow fiber ultrafiltration (UF) membranes with 0.03-micron pores to trap bacteria, viruses, parasites, and microplastics—removing 99.99% of harmful contaminants while keeping beneficial minerals like calcium and magnesium intact.

Key Benefits for Home Use:

  • Superior Protection: Millions of tiny hollow fibers create a physical barrier far more effective than standard carbon filters, ensuring safe drinking water without chemicals or electricity.

  • No Water Waste: Unlike reverse osmosis, UF produces zero wastewater—saving money and the environment while delivering fast, on-demand flow.

  • Better Taste & Purity: Retains natural minerals for crisp flavor; blocks odors, chlorine, and sediments effectively for everyday cooking and baby formula.

Backed by NSF/ANSI standards and proven in household systems worldwide, this technology gives families reliable, lab-grade purification at home.

Mineral Pro Model
with Essential Minerals

The 1THE Water Mineral Pro filter generates hydrogen-rich water right from your tap—tiny H₂ molecules that act like “bodyguards” for your cells, fighting harmful free radicals that cause aging, fatigue, and inflammation.

Why Hydrogen Makes a Difference:

  • Super Antioxidant: Neutralizes the worst oxidative stress (like hydroxyl radicals) without affecting good oxygen your body needs—think clearer skin, less tiredness.

  • Faster Recovery: Athletes drinking hydrogen water see 20-30% less muscle soreness after workouts; perfect for busy parents too.

  • Daily Protection: Reduces inflammation naturally, supports gut health, and boosts energy by stabilizing cell powerhouses (mitochondria).

Simple Science: Special mineral media in the Pro filter splits water into H₂ gas that absorbs instantly—no machines, no waiting, just pour and drink. Tastes crisp, hydrates deeper than regular water.

Safe, natural, and backed by 1,000+ studies—your family’s easy upgrade to antioxidant protection every sip.
