Efficient fine filtration — Captures small debris such as sand and sediment to keep pool water clear and reduce visible contamination. Easy, error-free installation — Each filter panel is numbered to match its position in the frame. Replace panels one at a time, starting with 4-1, for a straightforward, low-effort swap. Durable ABS frame — The rigid ABS plastic frame supports the filter media and prevents breakage during operation, improving service life and lowering the frequency of replacements. Stable construction for reliable performance — The frame maintains the correct spacing and pressure on the filtration layers so the filters perform consistently under normal pool circulation. Wide compatibility — Designed for use with a variety of pool sizes and filtration systems; panels are labeled to align with the corresponding frame locations for correct fit and orientation. High filtration performance — Ultrafine filter media handles different types of dirt and particulates, delivering noticeably cleaner water and reducing strain on pool pumps and other equipment. Low maintenance — Numbered panels and a robust frame simplify routine maintenance and replacement, saving time and reducing the chance of installation mistakes. Practical use scenarios: Backyard pool after heavy wind or rain — removes sand and mud tracked in after storms so the water clears faster without extra chemical treatment. Seasonal pool reopening and routine upkeep — replace individual numbered panels to refresh filtration performance without removing the entire assembly. Small commercial or community pools with frequent use — consistent filtration of fine particles helps maintain clearer water between professional cleanings. What you get: Numbered filter panels sized to fit the filter frame positions ABS plastic frames that support the filter media and resist breakage Ultrafine filtration material capable of trapping small sediments like sand and sludge How it helps you: Keeps pool water clearer by removing fine debris Simplifies replacement with a numbered, stepwise installation Reduces long-term replacement costs through a durable frame and reliable filtration performance
