These PETLIBRO 8-pack replacement filters are specifically designed for Dockstream Cat Water Fountain models PLWF005, PLWF105, PLWF115, PLWF106, and PLWF116, providing a 4-month supply of clean water. Each set includes individually packaged filters and pre-filter sponges, utilizing a professional 4-stage vertical filtration system.
