This premium pre-filter sponge provides an essential first layer of filtration, capturing larger debris and preventing excess waste from reaching the main filter. By doing so, it reduces clogging, maintains strong water flow, and extends the time between deep cleaning sessions. The durable sponge can be washed and reused multiple times, ensuring long-lasting performance. When the water flow noticeably slows down, simply replace it with a fresh sponge for continued optimal filtration.
