The U-shaped design ensures a secure fit around the pump, providing steady water flow and reliable filtration for daily use. (Please verify your fountain model before ordering.)","Effective Debris Filtration for Cleaner Water: Made from premium high-density polyurethane (PU) foam, these filters efficiently capture pet hair, dust, food particles, and other debris before they enter the water. This pre-filter layer supports cleaner water circulation and helps keep your pet’s hydration source fresh and hygienic.","Protects Pump & Extends Fountain Life: By blocking debris that could clog or strain the pump, these replacement filters help maintain stable fountain performance, prevent pump damage, and significantly extend the lifespan of your pet fountain.","Easy to Install & Replace: No tools required! Simply remove the old filter and insert a new one. For best results, soak the new filter in water for 5 minutes (then rinse for 30 seconds) before first use to restore its shape.

For optimal fountain hygiene and performance, replace the foam filter every 1–2 months (or every 1-2 weeks in summer / 2-4 weeks in winter for homes with heavy shedding or multiple pets)."]
