This Pentek C1 carbon filter cartridge reduces fine sediment and chlorine taste and odor in residential drinking water. It has a nominal (85%) filtration rating of 5 microns, and will reduce free available chlorine (FAC) at 2 parts per million (ppm) by at least 75% in up to 9500 litres at a recommended flow rate of 3.8 litres per minute (lpm. This cartridge is made of cellulose media impregnated with powdered activated carbon (PAC), reinforced by polyester backing and netting for strength and dirt-holding capacity. The nitrite butadiene rubber (Buna-N) gasket seals the cartridge against the housing (sold separately). The cartridge has an initial pressure drop of 4 pounds per square inch (psi) at a flow rate of 5 gpm, and it operates over a temperature range of 40 to 125 degrees F (4.4 to 51.7 degrees C). This filter cartridge meets National Sanitation Foundation/American National Standards Institute (NSF/ANSI) standard 42 for quality assurance, and is for use in various applications, including drinking water purification, laboratory water treatment, and film processing, among others.

The nominal filtration rating is for a particle removal efficiency of 85%. Chlorine reduction capacity is the minimum total amount of water for which the free available chlorine (FAC) at a concentration of 2 ppm is reduced by at least 75%.
Water filters remove undesirable particles, chemicals, and microorganisms from water by means of a semipermeable barrier, adsorption, or biological processes. They are made of densely packed synthetic or natural fibres that trap suspended particles, materials that block microbes or adsorb unwanted chemicals, or substances that cause a chemical change, such as acid neutralisation. For most residential, commercial, and industrial applications, water filters are manufactured in the form of replaceable cartridges that fit inside permanent housings. Filtration systems typically consist of a series of two or more types of filters, each designed to remove different contaminants. The performance of filters is measured by the minimum particle size that is blocked, the percentage of particles or microorganisms that are removed, the downstream concentration of unwanted chemicals, the maximum flow rate, and the amount of water that can be filtered before the filter must be replaced. Water filters are used in a wide range of applications, including drinking water purification, swimming pools, industrial processes, and irrigation, among others.
