So~Pure III Stage Water Purification System, a wall-mountable or under-counter filtration unit designed to enhance drinking water quality for homes and offices.Typical Core Filtration StagesMost standard 3-stage systems like this utilize a triple-cartridge progression to treat municipal tap water:Stage 1 (Sediment Filter): Uses a melt-blown polypropylene membrane to filter out visible debris like rust, sand, dirt, and silt. This clears up water cloudiness and protects subsequent filters from premature clogging.Stage 2 (Granular Activated Carbon / GAC): Effectively absorbs chemical residues, unpleasant tastes, and strong chemical smells (primarily chlorine or volatile organic compounds).Stage 3 (Carbon Block Filter / CTO): micro-particles, finer chemical traces, and chloramines to deliver crisp, clear drinking water.
