10 20 Inch Activated Carbon Filter Cartridge Granular Carbon Block Water Filter Element For Drinking Water Treatment Industrial Waste Gas Purification

Carbon filtering is a method of filtering that uses a piece of activated carbon to remove contaminants and impurities, utilizing chemical adsorption. When a material adsorbs something, it attaches to it by chemical attraction. The huge surface area of activated charcoal gives it countless bonding sites. When certain chemicals pass next to the carbon surface, they attach to the surface and are trapped.
When used for air purification, they are simply installed up high in the room's ventilation system, or they can operate as stand-alone units if that is more convenient.

Properties of activated carbon include:
• Has a capacity for virtually any vapor contaminant; it will adsorb some of almost any vapor.
• Has a large capacity for organic molecules, especially solvents.
• Will adsorb and retain a wide variety of chemicals at the same time.
• Has an extremely large capacity to catalytically destroy ozone, a major component of smog.
• Works well under a wide range of temperature and humidity conditions.
• Adsorbs odors and chemicals preferentially to moisture. It is not a desiccant and will release moisture to adsorb chemicals.
• Can be used as a carrier of one material to attract and hold or react with another material.
• Is inert and safe to handle and use.
