Compatible to Intelifil IF-SM-SCI020B 20"x4.5" Polyphosphate Scale & Corrosion Inhibitor Filter
NSF-certified clear bead media that prevents scale buildup and protects pipes and appliances through a self-healing phosphate coating. Sequester iron, reduce corrosion, extend equipment life.
Slow-Release Protection Against Scale and Corrosion
Self-Healing Coating
Slow-dissolving polyphosphate crystals apply a protective film to pipes and appliances, preventing mineral scale and corrosion from forming on metal surfaces.
Iron Sequestration
Binds dissolved iron in solution to prevent oxidation and precipitation, keeping water clear and reducing staining on fixtures and laundry.
NSF-Certified Media
Clear bead polyphosphate media meets NSF 42 and NSF 60 standards for material safety and performance in potable water applications.
Whole-House Flow
Supports up to 4 GPM through a 20" x 4.5" cartridge, suitable for whole-house, well, and light commercial installations in standard Big Blue housings.

Verify housing size before ordering.
Replacement Schedule
Replace Cartridge
Monitor water pressure and visible media depletion. Replace when polyphosphate crystals are mostly dissolved or pressure drop increases significantly.
Typical Household Use
For an average household of four, expect replacement intervals between 6 and 12 months depending on water usage and hardness levels.
Visual Inspection
Inspect cartridge through clear housing (if applicable) to monitor media level and ensure adequate polyphosphate remains for continued protection.
Chlorinated Water Only
Phosphates encourage bacterial growth. Use only with municipally chlorinated water or pair with UV, KDF, or ceramic protection on well systems.
Appliance Protection
Extends the life of water heaters, dishwashers, washing machines, and boilers by reducing scale formation and metal corrosion.
Easy Installation
Drop-in replacement for existing 20" x 4.5" Big Blue housings. No special tools or modifications required.
Cost-Effective Protection
120,000-gallon capacity delivers months of continuous scale and corrosion control at a fraction of the cost of equipment repair or replacement.
