The filter serves as a critical pre-filter stage to remove chlorine and organic chemicals that would otherwise damage the RO membrane. It also functions as a secondary sediment barrier at 5 microns, capturing particles that pass through upstream sediment filters. Compatible with standard 12-inch filter housings used in whole-house and RO applications. Also cross-references with KX Technologies and Matrikx +CTO-C specifications for broader compatibility.\n\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"pro-tip\"\u003e\n💧 \u003cstrong\u003ePro Tip:\u003c\/strong\u003e Replace carbon block filters every 6-12 months even if water flow seems normal.

Most AC-15 models use the 3\/8\" quick connect post filter included here, but a small number of early AC-15 units require a 1\/4\" quick connect inline filter instead.
