Standard Replacement Big Blue Filters/Cartridges for Whole House Water Filtration Systems - 4.5" x 20"
The first stage high capacity polypropylene sediment filter achieves filtration down to 5 microns. The second and third stage CTO Carbon Block filter uses high quality coconut shell carbon for maximum filtration efficiency and filter life. Both are tested by independent third-party to meet NSF/ANSI Standards. Both filters have a capacity of 100,000 gallon of water to supply one full year of clean water for a family of four.
High-quality Granular Activated Carbon (GAC) replacement cartridge. It absorbs chlorine, halide, organic contaminants, odors, and other impurities that contribute to bad tasting water. Depending on supplied water quality, it is expected to be replaced every 8 - 12 months.
