COMPATIBILITY

Filter Cartridge Compatibility

This Arrow housing accepts standard 20-inch by 4.5-inch diameter filter cartridges in sediment, carbon block, pleated, and specialty media configurations. The 1-inch NPT threaded ports provide higher flow capacity than standard 3/4-inch connections, making this housing ideal for whole house systems serving multiple bathrooms, light commercial installations, post-RO polishing in larger water treatment systems, and any application where flow rates exceed 10-15 gallons per minute. The transparent blue sump allows visual inspection of cartridge condition without depressurizing the system.
