Reef Diaper Disposable Filter Sock Starter Kit, Replaces Standard 4" Felt Socks, Freshwater and Saltwater Compatible, 2ea Flange Assemblies, 10ea Filter Elements

LOW-COST DISPOSABLE FILTER ELEMENTS: Never wash another nasty filter sock again! Just replace the disposable filter element and you have a perfectly clean filter sock every time. Additional elements sold separately on Amazon. QUICK AND EASY FILTER REPLACEMENT: The patented design allows you to simply change the filter element in seconds. Now you don't have to stink up your laundry room or use half-cleaned filter socks. DROP-IN REPLACEMENT FOR 4” FILTER SOCKS: The Reef Diaper replaces standard 4” filter socks and the seal fits sumps with a standard 3-3/4” bore. PLEATED ELEMENT FOR LARGER FILTER AREA: The pleated element has a filter area of over 300 square inches. The high strength filter fabric won’t deteriorate or tear and has the performance and life expectancy comparable to that of a 200 micron felt sock. FLANGE SEAL SECURES FILTER AND STOPS BYPASS: The built-in seal prevents waste from flowing past the sock and into your sump. It also prevents the filter from floating in applications where the socks are submerged.
