Constructed from non-woven polyester, the pleated media provides an increased surface area that captures particulate matter down to 30 microns. The filter measures 4.5 inches in outside diameter and 9.75 inches in length, sized to fit Big Blue style housings. It is rated for operating pressures up to 10 psi and handles water temperatures ranging from 40 degrees F to 125 degrees F. Plumbers and water treatment technicians install this filter as part of whole-house or point-of-entry sediment reduction systems.\u003c\/p\u003e\u003cp\u003eThis filter is suited for residential whole-house systems and light commercial plumbing applications where sediment loads such as sand, rust, and scale particles are present. It fits into standard Big Blue filter housings, making it a straightforward drop-in replacement during routine service intervals. Pool and plumbing service professionals commonly use this type of filter ahead of softeners, UV systems, or other treatment equipment to extend downstream component life.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e30-micron pleated filtration media captures sediment including sand, rust, and scale\u003c\/li\u003e\n\u003cli\u003eNon-woven polyester construction resists degradation in cold and warm water applications\u003c\/li\u003e\n\u003cli\u003ePleated design increases media surface area compared to wound or melt-blown alternatives\u003c\/li\u003e\n\u003cli\u003eRated for water temperatures from 40 degrees F to 125 degrees F\u003c\/li\u003e\n\u003cli\u003eSized for Big Blue style housings at 4.5 inches OD and 9.75 inches length\u003c\/li\u003e\n\u003cli\u003eMaximum operating pressure of 10 psi\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a drop-in replacement for Big Blue style cartridge filter housings accepting a 4.5-inch OD by 9.75-inch filter cartridge.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified water treatment technician.
