[10 Pack of Pet Fountain Filters] A pack of 10 filters.
[Pet Filter Compatibility] The filter has measurements of 2.75" x 1.75" x 0.25".
[High-Quality Filters] Equipped with a double filtration system consisting of a cotton layer and activated carbon. Efficiently filters hair and heavy metals, while keeping the water fresh and improving its taste.
[Recommended Replacement Frequency] Before using, soak the cat fountain filter in water for 2 minutes and rinse thoroughly under running water to prevent activated carbon dust from shedding into the water. Replace every 1 to 2 weeks in the summer and 2 to 4 weeks in the winter. If multiple pets are using the fountain, more frequent replacements are needed.
