Replace your Jandy filter cartridge every 12–18 months under normal conditions. Watch for replacement indicators such as persistent cloudy water despite proper chemistry, reduced water flow, increased pump pressure readings, visible tears or damaged pleats, or flattened filter media. Even with regular cleaning, the cartridge media gradually breaks down and loses filtration efficiency. SpiroPure filters match Jandy specifications precisely, ensuring proper fit and optimal filtration performance. Even better, SpiroPure models make proactive replacement affordable and protect your pool equipment from damage.
