About this item

  • This Watts Premium water filter replacement kit contains five, 11 inch filters: two 5 Micron sediment Filter (WP105311), two 5 micron carbon pre-filter (WP105351), and one 5 micron carbon post-filter (WP105341)
  • 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 while the carbon pre-filter and post filter reduce chlorine taste and odors and conditions the water before it is treated by the reverse osmosis membrane
  • The major benefits of these filters for your under sink filtration system is to trap and remove sediment as well as eliminate chlorine taste and odor to provide clean drinking water
  • To maintain top performance replace sediment and carbon pre-filters every 6 months and post-carbon every 12 months with our easy push button release that doesn't require you to shut off your water source

Not what I thought it was.
5 Stars
Not what I thought it was.
The product looked exactly like the filters I needed to replace. Same brand; same description; same colors. I could not get the filters to stay in the housing device. They kept falling out. I didn't know what I was doing wrong. I got on YouTube to try to find the answer, and there they were again. Same brand, same description, same colors. But I could not get those filters into the housing device. I finally had my "AHA!" moment, and put the old filter next to the new filter. The one from Amazon is on the left. The one I need is on the right. The description is not at all clear for novices like me. It looked like a duck. It walked like a duck, but it was NOT a duck. I searched Amazon for what I needed, but couldn't find it. Had to purchase it from a different vendor. The description needs to be more clear. Perhaps a picture like the one above with the cap off will help future buyers. I still LOVE Amazon! It's been a God-send during this pandemic.
