About This

  • Salt-Free Whole-House Water Descaler - EXPRT RF-20AS 20 × 4.5 in. Big Blue polyphosphate Siliphos cartridge stops hard-water scale, limescale & corrosion before they damage plumbing, faucets, and tankless water heaters—ideal water-softener alternative for city or well water.
  • Polyphosphate Scale Inhibition - Food-grade media forms a microscopic protective layer on copper, iron, galvanized & stainless-steel pipes, preventing mineral adhesion and helping stabilize chlorine without adding salt or chemicals.
  • High-Flow, Low-Pressure-Drop Design - Maintains 12–15 GPM at 80 PSI while treating up to 150 000 gal or 10–12 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.
  • 10-Micron Defense - Depth filter catches sediment up to 10 micron yet leaves beneficial minerals (does not lower TDS); pair with an EXPRT Reverse Osmosis system if dissolved-solid removal is required.
  • Unmatched Customer Service - Lifetime free tech support from US local support team. We stand behind our products and if you encounter any problems, please reach out to us immediately. We are happy to help!
