Iouaer Pet Water Fountain Filter Replacement Set Replacement Filter and Sponge for 4L Cat Drinker Pet Drinker Accessories

[Maintain Optimal Filtration]To continuous high-quality water, we recommend replacing filters and sponges every 2 to 4 weeks. If the water dispenser is to meet the needs of multiple pets, the replacement frequency may increase to keep the water clean and fresh. [Premium Filter and Pump Sponge]Each high-density pre-filter sponge is carefully designed to capture impurities before they enter the water, thereby improving overall filtration efficiency. In addition, the sturdy pump sponge prevents debris from entering the pump, significantly extending its service life. [Advanced Triple Filtration System]Our filter has a multi-layer filtration system, including high-density cotton, activated carbon, and ion exchange resin. This triple filtration system effectively captures hair, debris, chlorine, odor, and heavy metals, making the water purified, fresh, and enhancing the taste. [Wide Compatibility]This kit includes 6 replacement filters, 6 filter sponges, and 6 pump sponges, carefully designed to match the 135 fl oz / 4L wireless . Our commitment extends to providing a 12-month replacement service and a 24-hour customer support system to answer any questions. [Installation Tips]Before installation, soak the new filter in water for 5 minutes and rinse it thoroughly to remove excess carbon dust. This preventive step helps keep the water in the water dispenser clear and clean, ensuring that your pet is safe to drink.
