The main ingredient in almost all water filters is activated carbon, which is a form of carbon that has been processed to make it extremely porous and thus to have a very large surface area available for absorption of chemicals and impurities.
Furnace filter options abound in the 20x25x1" size category. We sell filters that range from MERV 4 to MERV 13, as well as a washable filter that you can reuse.
