Pentek CHLORPLUS 20" Jumbo Carbon Block Filter

This Pentek ChlorPlus 20 carbon block filter cartridge reduces chlorine and chloramine in residential and commercial drinking water. It has nominal filtration rating of 1 micron at an efficiency of 85%. The cartridge is made of bonded powdered activated carbon (PAC) media with a polyolefin core and shell and polyethylene outer netting. A Santoprene gasket provides a watertight seal. The filter will reduce free available chlorine (FAC) at 2 parts per million (ppm) by at least 75% in up to 50,000 gallons at a flow rate of 1 gallon per minute (gpm) and reduce 3 ppm chloramines by at least 75% in up to 1,000 gallons at a flow rate of 1 gpm. The filter has an initial pressure drop of 6 pounds per square inch (psi) at a recommended flow rate of 1 gpm and operates over a temperature range of 40°F - 180°F (4.4°C - 82°C). This carbon block filter cartridge is used for treatment of residential and commercial drinking water.


  • Nominal filtration rating - 1 micron
  • Initial pressure drop at 1 gpm - 6 psi
  • Chlorine reduction capacity - 83,000 gallons at 1 gpm
  • Chloramine reduction capacity - 12,000 gallons at 1 gpm
  • Operating temperature range - 40°F to 180°F (4.4°C to 82°C)
  • Maximum dimensions (H x W) - 9-3/4 x 2-7/8 inches (248 x 73 mm)

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%. Chloramine reduction capacity is the minimum total amount of water for which chloramines at a concentration of 3 ppm are reduced by 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 neutralization. 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.
