Comprehensive filtration These pre-filters are designed to trap soap, oils and other suspended particles before they reach the main filter, ensuring cleaner water and effortless spa hygiene maintenance. Easy installation Place the filter on the skimmer basket. The grooved notch design ensures perfect alignment, making installation quick and easy. Low maintenance Minimal upkeep is required. Depending on use, rinse weekly or more often and replace about every 3 months. Quick rinsing with water keeps the filters in optimal condition. Construction Made from synthetic fiber with a polypropylene frame, these filters are built for longevity. The robust materials withstand frequent use while maintaining high filtration efficiency. Use scenarios - In home spa setups to capture soaps, oils and particulates before they reach the main filter, helping water stay cleaner. - During periods of heavy spa product use (oil-based treatments, lotions) to protect the main filter and reduce clogging. - In high-traffic spa environments or rental properties where a quick, low-maintenance filtration solution is advantageous.
