A:Answer Thank you for your question! The standard packaging includes 3 filter sets, sufficient for 3 months of use.Regular cleaning and replacement are essential because the pump and filters continuously remove impurities (e.g., hair, dust) from flowing water, causing gradual buildup. To ensure your pet always enjoys fresh, clean water, we recommend: Cleaning filter: Every 1–2 weeks (based on visible dirt). Replace filter: Every 2–4 weeks (depending on filter condition).
