A large-capacity filtration unit designed for whole-house or commercial use, these systems typically employ a 20-inch long filter cartridge housed in a distinctive blue casing. The dimensions and design allow for a higher flow rate and extended filter life compared to smaller, standard-sized filters. These systems are used to remove sediment, chlorine, taste, odor, and other contaminants from water supplies.
The significance lies in providing cleaner, safer water throughout an entire building. This results in improved water quality for drinking, bathing, and appliance use, protecting plumbing systems from scale buildup and corrosion. Historically, these larger filtration solutions evolved to address the increasing demand for higher water quality and greater filtration capacity, particularly in areas with challenging water sources.
