Discover the OPISICEN 34-piece cat fountain filter set designed to fit VEKEN fountains at 95 oz/2.8 L, 67 oz/2 L, and 135 oz/4 L. The packaging aligns with the product imagery, featuring the OPISICEN logo and durable materials to reflect quality and care for your pet’s drinking water.
Each filter in the set uses a three-layer approach: activated carbon, ion exchange resin, and non-woven fabric. This combination targets hair, metals, and odors, helping water stay fresh for longer and encouraging regular drinking. A pre-filter sponge around the pump helps capture larger impurities and can contribute to smoother pump performance.
Included are two cleaning brushes of different sizes, built to access difficult corners and water pipelines. These tools support thorough maintenance so the fountain continues to run smoothly and stay hygienic for your pets.
For best results, replace filters and the sponge every 2 to 4 weeks, depending on how often your pets use the fountain and how many animals share it. Regular upkeep helps maintain water quality and system performance.
This set is tailored for OPISICEN users with 95 oz/2.8 L, 67 oz/2 L, and 135 oz/4 L fountains. Not compatible with 84 oz/2.5 L units. Filter dimensions are 3.9 x 3.9 x 0.4 inches; sponge measures 1.5 x 1.1 x 1.0 inch, designed to fit the intended models precisely.
Q: What fountain sizes are compatible with these filters?
A: Compatible with 95 oz/2.8 L, 67 oz/2 L, and 135 oz/4 L OPISICEN-compatible fountains.
Q: How often should I replace the filters and sponge?
A: Replace every 2–4 weeks based on pet usage and the number of fountains.
