High-quality material: Made from durable nylon, these filter protection nets are flexible, highly elastic and reusable. They withstand regular handling and washing without losing shape. Package includes: 2 x protective nets (filter not included). Protects your filter system: The high-density mesh captures fine debris—dust, pollen, insects, grass clippings and small leaves—before they reach and clog the water pump or pool filter. This reduces strain on the filtration system and helps maintain water clarity. Extends filter life and improves performance: By stopping fine residues earlier, the mesh cover helps your pool or whirlpool filter work more efficiently and can reduce how often you need to replace or deep-clean the filter element. Easy to install and maintain: The mesh fits over standard filter intakes and baskets, and can be quickly removed for rinsing. Because the net traps most small debris, you will need to clean the actual pool filter less frequently. Recommended replacement interval: every 4 to 8 weeks depending on debris load and usage. Use scenarios: After mowing or yard work: Place the mesh over your filter intake to catch grass clippings and small yard debris before they enter the filtration system. During pollen season or nearby tree drop: Reduce the amount of fine organic material reaching your pump and filter by using the net when pollen or small leaf fragments are present. While running the pool or whirlpool daily: Keep the mesh in place as a first-line defense to maintain smoother, more consistent filter operation and reduce maintenance time. Practical notes: Designed to work as a protective cover for pool and whirlpool filter systems. Simple to remove, rinse and reuse—no tools required. Replace the net every 4–8 weeks or sooner if visibly worn or heavily clogged to maintain protection and flow.
