COMPATIBILITY & APPLICATIONS
Where to Use the K2528
This inline GAC filter is designed for reverse osmosis post-filtration, under-sink drinking water systems, refrigerator and ice maker lines, beverage equipment, and drinking fountains. The quick-connect fittings make installation and replacement straightforward without tools. Use the K2528 as a final polishing stage after your RO membrane to enhance taste, or as a standalone inline carbon filter in any application where chlorine taste and odor reduction is needed. The compact 2-inch diameter fits tight spaces, and the coconut shell GAC media offers effective chlorine adsorption at 0.5 GPM flow.
💧 Pro Tip: The K2528 uses loose granular carbon, which works best in low-flow post-RO applications. For higher flow rates or sediment-heavy water, pair it with a sediment pre-filter to protect the carbon and extend service life. Replace annually or sooner if you notice taste or odor returning.
