Omnipure L5551 Sediment and GAC Carbon Combo Filter - Magic Mountain

The Omnipure L5551 is a high-quality L-Series Twist-Tap replacement filter cartridge designed for dependable point-of-use water filtration in a wide range of equipment and installations. This cartridge features a dual-media design—combining sediment filtration with granular activated carbon (GAC)—to help reduce particulate matter and improve taste and odor.

Built for convenience, the L5551 is part of Omnipure’s keyed L-Series system, which uses a quarter-turn style connection for fast cartridge changes when paired with the appropriate L-Series Twist-Tap head (sold separately). It is commonly used in bottleless water coolers and dispensers, and is also suitable for many other filtration applications such as refrigerators, icemakers, under-counter systems, drinking fountains, beverage equipment, and RO systems (as a pre/post filter stage). It can also be used in conjunction with commercial purification systems where compatible.
