【Dual-Action Filtration for Health】EffloToyz cat water fountain filter pack includes 4 main filter pads and 4 pre-filter sponges. The main pad traps hair and debris, while its core with coconut carbon and ion-exchange resin absorbs odors, softens water, and reduces scale-causing minerals to support your pet's urinary tract health. 【Universal Fit - Check Size for Compatibility】EffloToyz cat fountain filter replacement designed for most fountains with a square water pump and oval or rectangular filter slots. Main pad: 3.0" L x 1.7" W x 0.35" H. Pre-filter sponge: 1.4" L x 1.1" W x 0.37" H. Please measure your original filter before buying to ensure a perfect match. 【Easy Setup, Ready to Use】Simple installation: place the black sponge over the pump intake and secure the white pad in the filter slot. Before first use, rinse under water until wet to activate the media and remove any carbon dust. It's then ready for immediate use. 【Recommended Care for Pure Water】EffloToyz pet fountain filter replacement for optimal performance and water freshness, we recommend a simple routine: refill with fresh water and clean the fountain every 2-3 days, and replace this filter combo every 3-4 weeks. Consistent care is key to effective filtration. 【Dedicated Customer Support】Your satisfaction is our priority.
