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.

Helpful Filter Information

Not all filters have the same replacement schedule. Replace the RO membrane filter every two years. Replace all other filters every 6-12 months. Help keep your system sanitary by never using filters longer than 12 months, except the RO membrane filter, regardless of how much water you use.

Filter Replacement Schedule

We’ve taken the guesswork out of replacing your filters. Begin a filter replacement cycle by replacing all filters on your system (Filter Kit "YSM"). The following year, or sooner if recommended by the manufacturer, replace all filters except the RO membrane (Filter Kit "YS"). Repeat this cycle by following the helpful diagram below.
