Atlas Filtri PFAS ARMOR Cartridge 20" Big

$687.50

The Atlas Filtri PFAS ARMOR 20” Big Cartridge is an advanced whole-house filtration solution specifically engineered for PFAS (PFOA & PFOS) reduction, along with broad chemical improvement of mains water.

Designed for use in 20” Big Atlas Filtri housings, this high-performance cartridge uses a specialised activated carbon-based media with enhanced contact efficiency to target persistent chemical contaminants that standard carbon filters may not effectively reduce.

In addition to PFAS reduction, it also improves chlorine levels, taste, and odour, delivering cleaner, better-quality water throughout the entire home.

    • Media: Proprietary activated carbon-based filtration media

    • Function: PFAS, chlorine, taste, and odour reduction

    • Compatibility: 20” Big Atlas Filtri housings (mono/duo/trio systems)

  • Replace approximately every 6–12 months, depending on:

    • Water quality and PFAS load

    • Sediment levels (pre-filtration quality)

    • Household water usage

    Replace sooner if:

    • Flow rate drops noticeably

    • Water quality or taste changes

    • System pressure decreases

    This cartridge is designed to function as part of a multi-stage filtration system, not as a standalone solution.

    Best configuration:

    • Stage 1: Sediment filtration (to protect carbon media)

    • Stage 2: PFAS ARMOR cartridge (chemical + PFAS reduction)

    • Stage 3 (optional): Additional polishing or specialised media

    It performs best when upstream sediment is removed to prevent premature clogging and maximise lifespan.
