Microline S7206W-JG 3/8″ Inline Carbon RO Postfilter

The Microline S7206W-JG is a genuine replacement granular activated carbon (GAC) inline postfilter designed for select Microline reverse osmosis systems. Acting as the final polishing stage before treated water reaches the faucet, this carbon filter helps reduce chlorine taste and unwanted odors to maintain fresher-tasting water. It serves as an exact-fit option for newer Microline TFC-3, TFC-4, TFC-335, and TFC-435 reverse osmosis systems, and is also specified in the parts list for the Microline TFC-400.

This filter features an inline design measuring approximately 6.75 x 2.125 inches (nominal 2″ x 6″), providing a compact replacement option for applications with limited undersink space. It is equipped with 3/8-inch quick-connect ports for installation directly within a compatible water line. The unit ships with 1/4″ tube stoppers installed in the ports, which must be removed before connecting 3/8″ tubing by pushing in the outer collet ring and pulling out the center stopper until the tubing locks into place.

Compatible replacement part numbers for this filter include K2340, K2328, and K2336. Replacement is recommended every 6 to 12 months depending on local water conditions and system usage to help preserve consistent taste-and-odor performance. Buyers are advised to verify their current filter model, complete part number, and fitting size prior to purchase, as similar-looking filters may utilize different 1/4-inch quick-connect or threaded connections and are not interchangeable.
