Carbon filtering is a method of filtering that uses a bed of activated carbon to remove contaminants and impurities, using chemical adsorption. Each particle/granule of carbon provides a large surface area/pore structure, allowing contaminants the maximum possible exposure to the active sites within the filter media. One pound of activated carbon contains a surface area of approximately 100 acres. Activated carbon works via a process called adsorption, whereby pollutant molecules in the air to be treated are trapped inside the pore structure of the carbon substrate. Carbon filtering is commonly used for air purification. Active charcoal carbon filters are most effective at removing chlorine, formaldehyde and other volatile organic compounds (VOCs)
Activated carbon by its very nature is an odor magnet. Each granule of carbon has a specific amount of odor it can hold. When a carbon granule has adsorbed as much odor or VOC as it can it is saturated and needs to be replaced. Carbon filters cannot be washed to make them useful again.
How long will your carbon filter last? It depends on the environment the filter is in, and the amount of carbon in the filter. For this reason we suggest you replace your carbon filters regularly (every 3-6 months in more severe conditions) and purchase our super carbons which hold mor than 10 times more carbon than the standard carbon after filter.
A brief list of some of the VOCs your carbon filter will remove: acetone, formaldehyde, radon, paint fumes, pesticides, refrigerants, air fresheners, glues, spray lubricants, adhesive fumes, dry cleaning solvents, fabric cleaners, colognes, perfumes, rubbing alcohol, hair spray, tar, contact cement, benzene, toluene, xylene, methane, cooking odors, flatulence, smoke, and many many more.
