Microline TFC-400

Reverse osmosis system

Microline TFC-400 4-Stage RO Replacement Filters

The Microline TFC-400 4-stage RO system that uses a sediment filter to reduce sediment and product the automatic shut-off and later filters from clogging and debris. The second stage carbon block filter takes out the chlorine and chlorine by-products before the 50 GPD membrane filters impurities larger than .001 microns. The final stage is an inline carbon filter that treats for any lingering taste and odor to provide a polish to the filtered water. You can find and order all your filters at once in our replacement kits below.
