POOLNEAT Spa Filter Cartridge 2-Pack – 65 Sq.Ft, Fits Pleatco PLBS75, Unicel C-5374, Filbur FC-2971, 14.75" Length

Time to replace your spa's filter? This 2-pack of cartridges is a direct swap for popular models like Pleatco PLBS75, Unicel C-5374, Filbur FC-2971, and others. Each filter has 65 square feet of filtration area made from advanced trilobal fibers that trap dirt effectively and are easy to clean. The dimensions are 14.75\ long with a 2-1/8\ top/bottom opening. They're a premium material level, so they should last through multiple cleaning cycles. Just pop out the old, slimy one and slide this new one in—make sure to lubricate the o-ring on the filter housing. Regular replacement (usually once a year) keeps your water clear and your spa's pump running smoothly. A cost-effective way to maintain your hot tub without buying the expensive brand-name filters.
