Omnipure - E5786 - 14" x 2.5" E-Series GAC & 4 oz. Phosphate - Scale Inhibitor - Filter
E5786 14" x 2.5" GAC & Phosphate Scale Inhibitor
Granulated activated carbon filtration combined with 4 oz. polyphosphate to reduce chlorine, taste, odor, and scale buildup in one universal-fit cartridge
Dual-Action Water Treatment
GAC Chlorine Reduction
Granulated activated carbon media removes chlorine taste and odor while capturing particulates down to Class 1 levels for cleaner, better-tasting water
Polyphosphate Scale Control
4 oz. of polyphosphate inhibitor prevents lime scale and hard water deposits from forming on heating elements, fixtures, and appliance surfaces
Universal Cap Compatibility
Fits all permanent Omnipure E-Series filter heads without adaptors, making cartridge changes quick and straightforward across different installations
Reliable Flow Rate
Maintains 0.5 GPM flow at pressures up to 125 PSI and temperatures up to 100°F, suitable for under-sink RO systems and inline appliance applications
E5786 Filter Details

Replacement Schedule
Standard Replacement
Replace the E5786 cartridge every six months under typical residential use to maintain effective chlorine removal and scale inhibition
High-Volume Replacement
For commercial or high-volume applications, monitor total gallons filtered and replace when the cartridge reaches 2500 gallons, whichever comes first
Performance-Based
Replace sooner if you notice chlorine taste or odor returning, flow rate reduction, or increased scale formation on appliances and fixtures
Better Taste & Clarity
GAC media removes chlorine and particulates for clean, odor-free water
Appliance Protection
Polyphosphate prevents scale buildup on heating elements and valves
Long Service Life
2500 gallon capacity reduces replacement frequency and maintenance costs
Easy Installation
Universal cap fits all Omnipure E-Series heads without modification
