This Pentek EPM-BB carbon block filter cartridge reduces fine sediment and chlorine taste and odor in residential and commercial drinking water. It has a nominal (85 percent) filtration rating of five microns. The filter will reduce free available chlorine (FAC) at two parts per million (ppm) by at least 90 percent in up to 22,000 gallons at a flow rate of two gallons per minute (GPM). This cartridge is made of bonded powdered activated carbon (PAC) filter media wrapped in a polyolefin pre-filter with polyethylene outer netting. The nitrile butadiene rubber (Buna-N) gaskets seal the cartridge against the housing (sold separately). The cartridge has an initial pressure drop of 4.3 pounds per square inch (PSI) at a flow rate of two gallons per minute (GPM) and operates over a temperature range of 40 to 180 degrees Fahrenheit.

 Pentek EP-BB Carbon Block Water Filters (9-3/4" x 4-5/8"):

The nominal filtration rating is for a particle removal efficiency of 85 percent
 
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 90 percent
 
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 fibers 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 2 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
