COMPATIBILITY

System Compatibility

The E5528 features Omnipure's universal cap design that fits all standard E-Series permanent filter heads and most 10-inch inline housings with 2.5-inch sump capacity. This filter is designed as a pre-filter for reverse osmosis systems but can also be used in any application requiring chlorine and taste reduction at flow rates up to 0.5 GPM. The loose granular carbon media provides excellent contact time for chemical adsorption without the pressure drop associated with carbon block filters.

🔧 Pro Tip: Always install the E5528 before your RO membrane, not after. Chlorine will damage thin-film composite membranes within hours, and this GAC pre-filter is your primary defense against oxidative membrane failure.
