Michael Greene Jan 27, 2026 7:01 AM
An activated carbon water filter is a type of water filtration system that uses activated carbon to remove impurities and contaminants from water. Activated carbon is a form of carbon that has been treated with oxygen to make it highly porous and capable of adsorbing (not absorbing) various substances from water.
When water passes through the activated carbon filter, the porous surface of the carbon attracts and traps impurities such as chlorine, volatile organic compounds (VOCs), pesticides, and other chemicals. It can also remove some bacteria, however, it may not be effective in removing all types of bacteria or viruses.
Activated carbon filters come in different forms, including countertop, under-sink, and whole-house units. They are commonly used in households, as well as in industrial and commercial settings, to improve the taste, odor, and purity of water. Activated carbon filters are considered an effective and affordable method for water filtration, however, the lifespan and effectiveness of the filter can vary depending on usage and the quality of the water source.
