Watts Ro-Pure 531411 and 531407 RO System
This 4 stage RO system use sediment 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. Color-coded labels make it easier to identify the filters you need.
NOTE: Because of corporate restructuring by Watts, we no longer have access to RO Pure or Filter Pure filter cartridges and must be ordered from a dealer or online.
