About This
- COMPLETE 4-STAGE FILTRATION: Includes a sediment filter, a heavy metal KDF granular activated carbon (GAC) filter, a SoftGuard water softener, and a carbon block filter, designed to reduce sediment, chlorine, volatile organic compounds (VOCs), and improve taste and odor throughout the home
- UNIVERSAL COMPATIBILITY: These replacement cartridges are compatible with most whole‑house filtration housings that use standard 4.5″ diameter by 20″ filters, making installation easy in many setups
- PREMIUM TECHNOLOGY: The carbon filters are made using HydraCoil-enhanced melt‑blown polypropylene, with molecular pore structures offering high contaminant absorption and longer lifespan—up to ~20% longer than standard sediment filters
- EASY INSTALLATION AND MAINTENANCE: The system is plug‑and‑play—swap filters every 6–12 months for sediment and carbon filters to maintain optimal performance; no professional plumbing required for filter replacement
- EXCEPTIONAL CHLORINE REMOVAL: These filters offer a tenfold increase in chlorine absorption capacity, making them a standout choice for carbon block filtration in the market.
