Inline Polyphosphate Filter 2” x 10”

2" x 10" polyphophate inline reverse osmosis pre-filter to prevent scaling of hardness minerals and buildup of soluble iron on surfaces. Extends the life of RO components and membrane. A must for supply water greater than 7 grains. Acts by sequesting hardness minerals and iron, preventing scale formation and iron depositing on surfaces. The filter is refillable.

Our filters use SPER polyphosphate beads. See description and performance specifications below. Each filter comes standard with John Guest or Mur-Lok 1/4" QC x 1/4" MNPT male straight adaptors.

SPER PolyPhos® Polyphosphate Functions:

• SPER PolyPhos® is a unique form of polyphosphate beads 3mm – 5mm that sequester hardness minerals, prevent precipitation of minerals found in water supplies, as well as preventing internal mineral deposits within the water distribution system. This form of slow dissolving polyphosphate beads makes it especially beneficial in providing ongoing and stable PO4 water treatment.
• SPER PolyPhos® has a slower reversion rate compared with standard hexametaphosphate (SHMP) which makes it a more stable treatment and longer sequestering use life.
• Maintains water clarity through functional sequestration of minerals and scale control – resulting in fewer customer discolored water complaints.
• Reduced corrosion through cathodic “deadening” of the corrosion cell potential thereby inhibiting corrosion through out the water distribution plumbing.
• Gradual removal and inhibition of existing mineral scale deposits and prevention of these formations in hot water lines and residential water heaters.
• Since Slow Phos® is manufactured with highly stable dissolving protocol, the formulation of treatment concentration at the project site for injection remains effective over longer periods of time than standard phosphate treatments.
