Omnipure - E5521-P - 10" x 2.5" E-Series 10 Micron Carbon Block, Phosphate Filter - Scale Inhibitor
E5521-P 10 Micron Carbon Block with Phosphate Scale Inhibitor
The Omnipure E5521-P combines activated carbon block filtration with polyphosphate scale inhibition in a single cartridge. Built with a universal cap that fits all permanent E-Series heads, this filter delivers 10 micron particulate reduction, chlorine taste and odor removal, and scale control for equipment protection in one streamlined package.
Dual-Action Filtration and Scale Control
Carbon Block Core
10 micron carbon block media removes chlorine, taste, odor, and particulates down to 10 microns while maintaining consistent flow
Polyphosphate Treatment
Integrated phosphate media inhibits scale formation and corrosion, protecting downstream equipment and extending appliance life
Universal Cap Design
Proprietary cap fits all existing Omnipure E-Series permanent heads for quick cartridge replacement without tools
Commercial Specs
Rated for 0.5 GPM flow, 125 PSI max pressure, and temperatures up to 100°F for reliable performance in demanding applications
Standard Inline Size
2.5" diameter x 10" length inline cartridge fits most residential and commercial filter housings with standard dimensions
2000 Gallon Capacity
Service life of up to 2000 gallons or 1 year, whichever comes first, depending on water quality and usage patterns
Universal E-Series Installation
The Omnipure E5521-P is designed for use in any standard 10" x 2.5" inline filter housing with Omnipure E-Series permanent heads. Ideal for reverse osmosis pre-filtration, ice machine protection, beverage equipment, coffee brewers, and residential point-of-use applications where both chlorine removal and scale control are required. Compatible with existing Omnipure E-Series filter heads and housings across residential and commercial installations.
Omnipure E-Series filters are manufactured in the USA to NSF/ANSI standards for material safety and structural integrity.
