Premium Reverse Osmosis Water Filter Replacement Cartridges, 4-Pack

The Watts Premier RO Pure 4-Pack Filter Kit, a complete set of water filters for your under sink RO Pure (WP531411, WP531407) or Zero/Pure Plus (WP531517, WP531417) systems, is designed to bid farewell to unpleasant tastes and odors, and welcome fresh, great-tasting drinking water. This comprehensive kit includes three filters and a membrane, each tailored for specific filtration purposes, collectively ensuring crystal clear water every time.

The kit features one 5-Micron Sediment Filter (WP105311) for reducing dirt, silt, and rust that can affect the taste and appearance of your water. It also includes one 5-Micron Activated Carbon Pre-Filter (WP105351) and one 5-Micron Activated Carbon Post-Filter (WP105341) for conditioning the water and reducing chlorine taste and odors. Lastly, the kit comes with a 50 GDP Semi-Permeable Membrane (WP105331) for reducing TDS and contaminants like arsenic, lead, nitrates, percolate, and copper, as well as cysts, including Giardia and Cryptosporidium.

These top-performing 11-inch filters are crafted from only the highest quality materials for durability and maximum filtration. Filter life may vary based on local water conditions or use patterns, but Watts Premier recommends replacing the sediment and carbon pre-filters every 6 months, the carbon post-filter once a year, and the membrane every 2 to 5 years.

The user-friendly design of these filters sets them apart, with each one denoted by a different color for easy identification: red for sediment, yellow for pre-filter, blue for post-filter, and green for membrane. Furthermore, they are equipped with a push button release that allows for hassle-free replacement without shutting off the water source. Easily change out filters with a quick push of a button - no special tools required!

Please note that this kit will not fit the Watts 1/4 Turn Kwik-Change RO System.
