Anyone who owns a Jandy cartridge filter system please read this. As of today, 3/8/12 it has been discovered that Jandy is currently shipping out Unicel cartridge filters from their facilities in original Jandy replacement cartridge boxes. My distributor just confirmed that over a year ago Jandy stopped using a Chinese company to make their Jandy private label cartridges because of quality concerns. They switched to Unicel. The problem is, they didn't tell anyone. Everyone is still paying Jandy original equipment cartridge prices for Unicel filters coming in a Jandy original equipment box!!!. Please save your money and just order a Unicel replacement filter for Jandy. We sell Unicel filters as well as Pleatco filters that fit almost every Jandy cartridge filter model. We will no longer be selling Jandy original equipment filters on our site as a result of this discovery.
