16 Sets Cat Water Fountain Filters for 108Oz/3.2L and 67Oz/2L

Our 16 Sets Cat Water Fountain Filters are specially designed for our 108oz/3.2L and 67oz/2L Stainless Steel Cat Water Fountain (also compatible with PLWF003). To maintain clean and fresh water for your pet, the carbon filter should be replaced every 4 weeks during hot weather (and once every 2 weeks for mosquito prevention). The foam filter should be replaced every two months. Each set includes 4/8 filters and 4/8 sponges, making it easy to replace and providing added protection for your pet. The first filter blocks hair and debris, the middle filter removes residual heavy metals, and the third filter promotes healthier, high-quality flowing water for your pet to drink throughout the day. Before use, soak the filter in a clean bowl for 5 minutes to ensure proper function. Note: the filter must be completely soaked before turning on the fountain to avoid overflow. Do not soak the filter in the fountain tank to avoid surface dust
