This Pentek P1-20 spun polypropylene filter cartridge reduces sand, silt, scale, and rust particles in residential, commercial, and municipal drinking water. It has a nominal filtration rating of 1 micron at an efficiency of 85%. The filter is made of spun polypropylene fibers for resistance to s and bacteria. It has an initial pressure drop of 0.6 pound per square inch (psi) at a flow rate of 10 gallons per minute (gpm), and operates over a temperature range of 40 to 145 degrees F (4.4 to 62.8 degrees C). This spun polypropylene filter cartridge meets National Sanitation Foundation/American National Standards Institute (NSF/ANSI) standard 42 for quality assurance, and is used for of residential, commercial, and municipal drinking water. Specifications -------------- Nominal filtration rating 1 micron Initial pressure drop at 10 gpm 0.6 psi Temperature range 40 to 145 degrees F (4.4 to 62.8 degrees C) Maximum dimensions (H x W) 20 x 2-3/8 inches (508 x 60 mm) Materials certification NSF/ANSI standard 42 The nominal filtration rating is for a particle removal efficiency of 85%. 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, s, 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 s, or substances that cause a change, such as 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 s, the maximum flow rate, and the a 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.
