The Drinkwell Premium filters feature a six compartment plastic frame that evenly distributes the granulated charcoal throughout the filter cartridge, providing for a more thorough and complete filtration process. The Drinkwell Platinum Premium Filter will fit any size Drinkwell Fountain and can be found at your local Drinkwell retailer.
The filter fits narrow side down and the black side faces the front of the fountain. The filter will slide easily into place. For Drinkwell Platinum users insert the filter into the two triangular slots in the center fo the housing. For users of the original Drinkwell, the filter will fit into the housing diagonally. - Rinse the filter thoroughly under cool water before placing into the housing. This will remove any loose charcoal dust, which is harmless. A small amount of charcoal dust may shred for the life of the filter. This is normal and not harmful to your pet. Filters should be changed approximately every 4-8 weeks depending on the size and number of pets using the fountain.
- The Drinkwell High Capacity Filter is sectioned into 6 individual compartments to allow for an even distribution of charcoal throughout the filter. This provides more consistent filtration of the water to remove bad tastes and odors, keeping the water fresher and cleaner than before.
