Topway Global (TGI) EZ-450

Reverse osmosis system

TGI EZ-450 4-Stage RO Replacement Filters

This 4 stage Topway Global RO system uses sediment and GAC 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.
