## Description

This Pentek EP-20BB carbon block filter cartridge reduces fine sediment and chlorine taste and odor in residential and commercial drinking water. It has a nominal (85%) filtration rating of 5 microns. The filter will reduce free available chlorine (FAC) at 2 parts per million (ppm) by at least 90% in up to 40,000 gallons at a flow rate of 4 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 5.5 pounds per square inch (psi) at a flow rate of 5 gallons per minute (gpm), and operates over a temperature range of 40 to 180 degrees F (4.4 to 82.2 degrees C). This carbon block filter cartridge meets National Sanitation Foundation/American National Standards Institute (NSF/ANSI) standard 42 for quality assurance, and is used for purification of residential and commercial drinking water.SpecificationsNominal filtration rating5 micronsInitial pressure drop at 5 gpm5.5 psiChlorine reduction capacity40,000 gallons at 4 gpmTemperature range40 to 180 degrees F (4.4 to 82.2 degrees C)Maximum dimensions (H x W)20 x 4-5/8 inches (508 x 118 mm)Materials certificationNSF/ANSI standard 42The 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 90%.H is height, the vertical distance from lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.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 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.Pentair manufactures industrial, commercial, and residential water filtration components and systems. The company, founded in 1966 and headquartered in Minneapolis, MN, meets International Organization for Standardization (ISO) standards 9001 and 14001 for quality assurance.

## Questions & Answers

**Q: where is it made?**
A: This product is made in the USA.

**Q: when it says "reduces . . . chlorine taste" does this mean it removes chlorine from water or just alters it in some way that you don't taste it?**
A: No carbon will remove the chlorine may not be 100% but you will definitely tell a difference if chlorine is all your dealing with then no need for a 5mic carbon go just carbon it's cheaper if you ever decide you want a water softener it's best to remove the chlorine first... But a great 1x20 filter

**Q: Does it fit inside 10filter housing**
A: I assume you are asking if this cartridge fits in the shorter "big blue" filter housing ... While its actually closer to 13"×7" they refer to it by average filter size which is 10"×4.5". That's a really good question since nowhere does it state which housing to use with it. Dimensions shown for this cartridge are 4.6"×4.6"×9.8". Dimensions for the Big Blue® housing are approx 7.25"×7.25"×13" and calling for a filter approximately 4.5"×10".  This is the housing and filter combination that I use. The cartridge fits snugly and allows proper water flow in that housing.

**Q: Our municipal water in San Francisco is pretty clean, how long before this filter cartridge is recommended for replacement?**
A: This cartridge is rated for 6,000 gallons.  If kitchen sink only, should provide drinking water for a year.  If whole house, run 2 in parralel to get needed flow, the pair might last 3 months.
