BEBANG Cat Water Fountain Filters, 6 Pack Carbon Filters and 3 Pack Pre-Filter Sponges, Dog Water Fountain

BEBANG replacement filters include 6 Pack carbon filters and 3 Pack pre-filter sponges. Through a multi-layer filtration system, every drop of water can remove all impurities, providing oxygen rich and better tasting water. The system includes activated carbon to eliminate odors, ion exchange resin to remove heavy metal ions and soften water quality, non-woven fabric to capture cat hair and impurities, and built-in pump sponge to further filter debris, effectively preventing blockage and damage. For optimal performance, it is recommended to soak the filter for 3 minutes and rinse for 30 seconds before use, and replace the filter every 2-3weeks to maintain the filtering effect. If you have multiple pets, it is recommended to clean the fountain more frequently and replace the filters.
