How Does a Carbon Filter Work?
The activated carbon material that is inside a tank or filter housing works like a sponge, attracting and holding contaminants as water passes through it. Carbon is very porous and has an unusually high surface area for contaminant removal. A teaspoon of activated carbon has the total surface area equal to a football field. This contact time causes the contaminants to be adsorbed from the water supply. Other contaminants may be filtered out like a strainer and trapped. Once you identify what your specific water problem is you can then decide which type of carbon filter system will solve your water quality issues.
