The 20x2.5 inch block filter is designed to process up to 10,000 gallons of water at a chlorine concentration of 2ppm or 20,000 gallons at 1ppm. This high-capacity carbon block filter effectively removes 99% of chlorine, taste, and odor from the water. It features high-purity coconut shell activated carbon combined with food-grade, non-shedding polypropylene fabric to ensure that carbon fines, impurities, and sludge are captured for cleaner water output. The filter is made from BPA-free materials and includes a silicone O-ring to prevent any bypass issues, ensuring consistent filtration performance.
