Watts Premier 531161 RO Pure Plus 6 Pack Filter Kit
RO Pure Plus 6 Pack Filter Kit
This complete replacement kit contains everything needed to maintain your Watts Premier RO Pure Plus or Zero Pure Plus reverse osmosis system for one full year. The six-piece set includes two sediment pre-filters, two carbon pre-filters, one 50 GPD membrane, and one VOC carbon post-filter, delivering four stages of filtration to reduce TDS, chlorine, volatile organic compounds, and common contaminants like arsenic, copper, lead, and cysts.
Four-Stage Filtration Process
Particulate Removal
Two 5-micron sediment pre-filters (105311) trap dirt, silt, rust, and other particulate matter that affects water clarity and taste. Push-button release design makes filter changes simple.
Replace every 6 monthsChlorine & Odor Reduction
Two 5-micron carbon pre-filters (105351) reduce chlorine and other materials that cause taste and odor issues, protecting the membrane and improving water quality before the RO stage.
Replace every 6 monthsReverse Osmosis Separation
The 50 GPD membrane (105331) reduces total dissolved solids and removes contaminants including arsenic, copper, lead, and cysts through semipermeable membrane filtration.
Replace every 2-5 yearsVOC Post-Filtration
The 1-micron VOC carbon post-filter (105381) removes volatile organic compounds like atrazine, 2,4-D, and lindane after the storage tank, functioning as a final polishing stage before dispensing.
Replace annuallySystem Requirements
Designed for Watts Premier RO Pure Plus and Zero Pure Plus reverse osmosis systems (models 531417, 531517). Also compatible with Watts Premier RO Pure systems (models 531411, 531407). Verify your system model before ordering to ensure proper fit with push-button filter housings.
