Understanding Two-Stage Undersink Filtration
Water filtration relies on progressive layers to capture particles of varying sizes before water reaches your kitchen faucet. Think of it like a security checkpoint with multiple verification stages; the initial polypropylene layer acts as a coarse guard that catches larger sediment, rust, and suspended solids. Once the bigger particles are blocked, the water passes through the compressed carbon block filter. This second stage uses activated carbon to adsorb microscopic impurities, chlorine taste, and lead as small as 0.5 microns. By dividing the workload between two distinct media types, the system prevents premature clogging and ensures consistent flow rates while delivering crystal-clear, great-tasting water.
