This Pentek DGD-7525 spun polypropylene filter cartridge reduces sand, silt, scale, and rust particles in residential, commercial, and municipal drinking water.It has two separate gradient layers for higher particle reduction efficiency and dirt-loading capacity than standard spun or string-wound cartridges.The nominal filtration rating of the pre-filter layer is 75 microns, and the rating of the post-filter layer is 25 microns.The filter is made of spun polypropylene fibres for resistance to chemicals and bacteria.It has an initial pressure drop of less than 0.5kg per square inch (psi) at a flow rate of 37.9ls 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 treatment of residential, commercial, and municipal drinking water.

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, 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 application...
