Microline TFC-335

Reverse osmosis system

Microline TFC-335 3-Stage RO Replacement Filters

This 3 stage RO system uses a carbon block pre-filter to reduce sediment, chlorine and chlorine by-products before the 50 GPD membrane filters out impurities larger than .001 microns. The GAC post filter treats for taste and odor. You can find and order all your filters at once in our replacement kits below. This system is also known as model number TFC-35A.
