Topway Global (TGI) GTS-550

Reverse osmosis system

TGI GTS-550 5-Stage RO Replacement Filters

This 5 stage RO system uses sediment, GAC and carbon block pre-filters to reduce sediment, chlorine and chlorine by-products before the 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.
