Maintain the highest standard of hygiene for your canine companion with the PETNF replacement filter set. Designed exclusively for the PETNF D2223, D2341, D2322, and D2340 stainless steel water fountain models, this four-pack ensures a consistent supply of pristine water for large dogs. The filtration system utilizes a specialized 7-layer vertical architecture that distinguishes it from standard flat filters. By processing water through multiple distinct stages, the system effectively removes hair, sediments, and heavy metals while preserving the natural oxygen content. This comprehensive approach not only safeguards your pet’s health but also improves the taste of the water, encouraging increased hydration throughout the day.

Each filter incorporates high-density activated carbon and ion exchange resin to deliver superior purification performance. The vertical orientation of the layers allows for a more efficient flow path, ensuring that every drop of water is thoroughly treated before reaching the bowl. While the filters are engineered to last approximately two months, we recommend a replacement interval of every two weeks to guarantee optimal water quality and system efficiency. This proactive maintenance schedule helps prevent the buildup of impurities and keeps the fountain operating at peak performance. Please note that this package contains only the replacement filters; the stainless steel base unit must be purchased separately to complete the setup.

Installation is straightforward and requires no specialized tools. Before placing the new filter into the fountain, soak it in water for two minutes to saturate the materials. Thoroughly rinse the unit under running water to remove any initial dust or loose particles. Once prepared, insert the filter into the designated holder of the PETNF fountain. This user-friendly design makes routine maintenance simple, allowing pet owners to focus on the well-being of their furry friends. By adhering to the recommended replacement schedule, you provide your dog with a reliable source of clean, fresh water that supports their overall vitality and comfort.
