Watts Premier WP105381 VOC Filter for RO Pure Plus – 1-Micron Replacement Kit

Overview

The Watts Premier WP105381 VOC Filter is designed for under-sink RO Pure Plus and Zero/Pure Plus systems. It targets volatile organic compounds (VOCs) commonly found in tap water and provides a final polishing step to help improve the water’s flavor and aroma. With 1-micron filtration, this cartridge works to reduce fine impurities as the water passes through your system, contributing to a crisper sip from your faucet.

What you get and how it helps

This 11-inch cartridge features a distinctive silver label and cap, helping you identify it quickly within the Watts Premier filter lineup. The included 1-Micron VOC Filter (WP105381) is rated for a flow of 0.05 GPM (1.89 LPM) per spec, and it doubles as a final polishing stage to enhance the water’s taste and clarity.

• VOC FILTER REPLACEMENT: Designed for your under-sink RO Pure (WP531411, WP531407) or Zero/Pure Plus (WP531517, WP531417) systems, this filter targets VOCs and filters particles as small as 1 micron. Note: it will not fit Watts 1/4 Turn Kwik-Change systems.

Easy installation, maintenance, and compatibility

Replacement is straightforward thanks to the push-button design—swap the old cartridge for the new one without interrupting your water line.

Always consult your system manual if you’re unsure which filter fits your unit.

Real-world use and results
