Features

  • This Watts Premium water filter replacement kit contains five, 11 inch filters: two 5 micron sediment filter (WP105311), one 5 micron carbon pre-filter (WP105351), one 50 GPD membrane (WP105331), and one 1 micron VOC (Volatile Organic Compound) carbon post-filter (WP105381)
  • It is compatible with the RO Pure (WP531411, WP531407) and Pure Plus (WP531417, WP531517) line of reverse osmosis systems but will NOT fit the Watts 1/4 turn Kwik Change reverse osmosis system
  • The sediment pre-filter reduces dirt, silt and rust; the carbon pre-filter reduces chlorine taste and odors and conditions the water before it is treated by the reverse osmosis membrane; the 50 GPD membrane reduces TDS and other contaminants like chromium, arsenic, copper, lead, and the VOC Carbon Post-Filter reduces chemicals like MTBE's, atrazine, benzene, 2,4-D, and lindane
  • The major benefits of these filters for your under sink filtration system is to trap sediment, reduce TDS and VOCs, and eliminate chlorine taste and odor to provide clean drinking water
  • To maintain top performance replace sediment and carbon pre-filters every 6 months, VOC carbon filter once a year, and the membrane every 2 to 5 years with our easy push button release that doesn't require you to shut off your water source

  • These are the ones that are clogged
Size: 2 Count (Pack of 1) Style: Replacement Kit
If your system has low pressure go ahead and just replace these two. Then see what happens. It was most likely one of these that was clogged

  • Exact replacements
Size: 6 Count (Pack of 1) Style: Replacement Kit
They’re exact replacements and installed easier than any other filtration system I’ve used. They come with a plastic cap under vacuum I believe, not nitrogen filled and again sealed in it’s individual clear plastic shrink sealed wrapper and then placed side by side and sealed again as a single package. Then placed and shipped in a perfect size Amazon box. In my opinion very clean and safe. ... show more
