What customers say
Users overwhelmingly praise this filter for delivering exceptional, crystal-clear pool water, crediting its large surface area for extended cleaning intervals. The modular design offers superior dirt holding and reliable performance across seasons. However, this high performance is balanced by significant ownership considerations. Maintenance is frequently described as cumbersome and physically demanding, especially with the heavier elements. Additionally, the initial purchase price and replacement cartridge costs are substantial. The consensus is that this filter is a durable workhorse, best suited for owners prioritizing top-tier water quality and capacity over ease of maintenance and budget concerns.
