Are the Platinum Filters compatible with the Original Fountain and Big-Dog Fountain or Are the Original Filters compatible with the Platinum Fountain?
Both kinds of filters are a standard size and shape and fit all models of Drinkwell pet fountains. The difference is in the quality of the water filtration. The original fountain filters are divided into 2 segments, distributing the charcoal throughout the filter, which removes bad tastes and odors. The new Drinkwell High Capacity Filter is sectioned into six individual compartments to allow for a more even distribution of charcoal throughout the filter. The charcoal removes bad taste and odors, keeping the water fresher and cleaner for your pet. Both filters should be changed every 2-4 weeks to keep your pet’s water fresh and clean.
