About This

• Salt-Free Whole-House Scale Control - Advanced Filtersorb SP3 Nucleation Assisted Crystallization (NAC) media converts hard-water minerals into harmless micro-crystals, delivering continuous limescale removal & prevention at every tap—an eco-friendly water-softener alternative for city or well water.
• Filtersorb SP3 Beats Polyphosphate - Polyphosphate cartridges merely coat plumbing to prevent new deposits, but Filtersorb SP3 NAC media actually dissolves existing limescale while preventing future build-up, delivering full-spectrum scale removal and prevention for longer-lasting pipes, fixtures, and water-using appliances.
• Pair With Catalytic Carbon for Maximum Protection — Placing a whole-house catalytic carbon cartridge(EXPRT RF-1021) before the Filtersorb SP3 anti-scale filter strips chlorine, chloramines, VOCs and hydrogen-sulfide odor, shielding the NAC media from oxidation, extending its 2-3 year lifespan and delivering cleaner, fresher, and scale-free water to every tap.
• High-Flow, Low-Pressure-Drop Design - Maintains 12–15 GPM at 80 PSI while treating up to 130 000 gal or 8–12 months*—perfect for large homes and light commercial use. (May vary depending on the quality of the feed water).
• Universal Point-Of-Entry Fit - Drops into any standard 4.5 × 20 in. “Big Blue” housing, making whole-house anti-scale filter replacement quick and tool-free
• No Salt, No Backwash, Low Maintenance - Salt-free scale-inhibitor needs no brine, electricity, or drain line; keeps healthy minerals, leaves TDS unchanged, and is safe for septic systems
