6-Pack Cat Water Fountain Filters Compatible with 2.5L Cat Water Fountains, Replacement Filters with Activated Carbon/Foam/Sponge for 84 FL oz Pet Water Fountains

【Triple Filtration System】 These cat fountain filters feature a 3-layer filtration system: high-density microporous non-woven fabric filters out large particles and impurities; activated coconut shell carbon removes impurities through absorption; and ion-exchange resin removes heavy metal ions, resulting in softer water quality.

【Keep Pets Healthy】 The upgraded water fountain filter consists of a layer of cotton, activated carbon, and ion-exchange resin.

It effectively removes hair and heavy metals and improves the taste of water, so pets can drink clean, fresh water throughout the day, helping to increase water intake and reduce the risk of urinary tract infections. [Regular Replacement] To maintain filtration, replace the filter every 2-4 weeks and the black noise-absorbing sponge and rectangular cat fountain pump sponge every 2 months. If you have more than one pet, please replace the filter, sponge, and clean the fountain more frequently. [Instructions for Use] To prevent activated carbon dust (which is harmless to your pet) from falling into the water, soak the filter in water for 5 minutes before replacing it, then rinse thoroughly under running water before use to keep your cat's water clean and safe to drink. clean.
