Osmio 4.5 x 10 Inch 10" F-Guard PFAS/Fluoride Filter 2 micron

The Osmio F-Guard is designed to tackle chemical standard filters will strugggle to reduce. Particularly PFAS and Fluoride. The filter is made from two types of activated carbon, combined with proprietary Zeolite minerals, Metal Scavengers and Activated Mineral Phosphates structurally bound with polymers into a highly porous block filter form. Made in the USA, the filter combines the highest FDA-compliant raw materials, with cutting-edge manufacturing methods resulting in unparalleled performance in an exclusively U.S.A. Manufactured product.

• PFAS & Fluoride reduction for around 11,000 litres or 3000 US gallons
• Class II Porosity for less pressure drop compared with typical Class I lead reduction filters
• Greatest Chloramine reduction to non-detect levels
• Low Pressure Drop
• Certified for materials safety by NSF International

  Osmio F-Guard – Advanced PFAS & Fluoride Reduction Filter

  The Osmio F-Guard is an advanced, high-performance filtration solution engineered to address modern chemical contaminants that standard carbon filters often struggle to reduce. Specifically developed to target PFAS (“forever chemicals”) and fluoride, the F-Guard represents a new generation of water filtration media designed for today’s increasingly complex water supplies.

  At the core of the Osmio F-Guard is a sophisticated, multi-media composite block combining two types of premium activated carbon with proprietary zeolite minerals, metal scavengers, and activated mineral phosphates. These materials are structurally bound with advanced polymers and formed into a highly porous solid block filter, maximising contaminant contact time while maintaining excellent flow characteristics.

  This unique media composition allows the F-Guard to effectively reduce PFAS compounds, fluoride, chloramine, chlorine, and a broad spectrum of chemical impurities, delivering noticeably cleaner, better-tasting water without the excessive pressure drop associated with conventional high-density carbon filters.

  Manufactured exclusively in the USA, the Osmio F-Guard uses only the highest-grade FDA-compliant raw materials, combined with cutting-edge U.S. manufacturing techniques. The result is exceptional consistency, durability, and performance — setting it apart from mass-produced alternatives.

  Performance & Capacity

  • PFAS & Fluoride reduction for approximately 11,000 litres (3,000 US gallons)
  • Class II porosity for lower pressure drop compared to typical Class I lead reduction filters
  • Exceptional chloramine reduction to non-detect levels
  • Low pressure drop to help maintain household flow rates
  • NSF International certified for materials safety

  Unlike many dense Class I carbon block filters, the Osmio F-Guard features Class II porosity, enabling significantly improved flow performance while maintaining high contaminant reduction efficiency. This makes it particularly suitable for whole-house and point-of-entry systems where maintaining water pressure is essential.

  The Osmio F-Guard is the ideal choice for households seeking advanced protection against modern chemical contaminants — delivering cleaner water through innovative materials, intelligent design, and uncompromising U.S. manufacturing quality.
