Microline TFC-300

Reverse osmosis system

Microline TFC-300 3-Stage RO Replacement Filters

The Microline TFC-300 3 stage RO system that uses a combination sediment/carbon pre-filter to reduce sediment, chlorine, and chlorine by-products to prevent clogging and damaging the 50 GPD TFC membrane. The 50 GPD TFC filters out impurities larger than .001 microns. The third stage GAC carbon post filter treats for taste and odor to add a final polish to the water. You can find and order all your filters at once in our replacement kits below.
