Measurements Replaces Outer Diameter 8" Pleatco PBF36-M Length 5 7/8" Filbur FC-0536 Top Hole Handle Bottom Hole 2" long modified ACME Unicel - Clearly the BEST POOL & SPA FILTERS Things to Consider When Purchasing a Bullforg Spa Filters Cartridge Replacement Does your cartridge meet the specifications of the NSF certification for your filter system? NSF certifies systems based on a stated square footage and type of media specified by the system manufacturer. Is the basis weight of the media in your cartridge the same as that specified by the system manufacturer? Assure you are not getting a cartridge with media that weighs 3 ounces per square yard in a system that specifies elements with 4 ounces per square yard. "4 oz media" contains 33% more fibers by weight than "3 oz media". This significantly increases its durability， filtration matrix and dirt trapping ability and provides for longer， more efficient filtration. Is the media in your cartridge finished with a "flat bond" or a "point bond"? The point bonding process fuses the area on and around the bond for no or low water flow; this effectively reduces the surface area of your element up to 20%! Does the square footage of your cartridge match that of your filter systems? Under or oversizing your elements may not yield the best system performance. Does your replacement cartridge have support bands like the original from the system manufacturer did? The support bands on a cartridge play an important role in maintaining pleat spacing and preventing pleat bunching in the tank and during cleaning. How does your cartridge balance "dirt holding" and "cleanability?" Dirt holding and cleanability are a tradeoff. Cartridges that hold more dirt are going to be harder to clean. Made in the USA
