    The Aries AF-20-2015-BB Comparable KDF and Carbon Water Filter by Tier1 is 20 inches by 4.5 inches. The filter can be used in all number 20 Big Blue or number 20 Big Boy housings. Filter cartridge contains 4 pounds of KDF-55 along with coconut shell granular activated carbon to reduce chlorine taste and odor, water-soluble heavy metals, and controls scale, bacteria, and algae in your water. KDF is a patented medium that consists of high purity copper-zinc granules that use redox (exchange of electrons) to effectively reduce chlorine and heavy metals as well as controlling microorganisms in potable water. This filter restricts water flow significantly and, if used as a whole house filter, may require installation in a parallel configuration rather than a series configuration to improve the flow rate.
