Leaves your pool spotless. The filters are designed to retain only the larger debris and allow the finer debris to pass through, preventing the cartridges from clogging as quickly when the pool is particularly dirty as when it is particularly dirty. The pool opens in the spring. Superior quality: The ABS plastic frame is stronger and more durable. It securely holds the filter layer and prevents it from breaking during operation. Washable: Washable and reusable, these filters can last 2 to 4 months, or even 3 years if used correctly. Rinse the filter every 4 to 5 minutes, or every 6 weeks for optimal performance.
