Its polypropylene string-wound construction offers superior dirt-holding capacity and supports flow rates up to 10 GPM with a low pressure drop of 5 PSI.

## Description

This Pentek WP.5BB97P string-wound polypropylene filter cartridge reduces fine sediment, rust, and scale particles for municipal drinking water and industrial fluid applications. It has a nominal filtration rating of 0.5 micron at an efficiency of 85%. The filter is made of polypropylene fiber cord that is wound in a precise pattern on a rigid polypropylene core for greater surface area, providing a higher dirt-loading capacity than standard wound cartridges. It has an initial pressure drop of less than 5 pounds per square inch (psi) at a maximum flow rate of 10 gallons per minute (gpm), and operates over a temperature range of 40 to 165 degrees F (4.4 to 74 degrees C). This string-wound filter cartridge is for use in various applications, including drinking water purification, irrigation, and industrial processes, among others.SpecificationsNominal filtration rating0.5 micronInitial pressure drop at 10 gpm5 psiTemperature range40 to 165 degrees F (4.4 to 74 degrees C)Maximum dimensions (H x W)9-7/8 x 4-1/2 inches (251 x 114 mm)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 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: How often does this filter need to be replaced? We are using it as a whole house filter.**
A: Ours is a whole house system as well. We need to replace the filter on average about every 4-6 weeks. However, that really depends on the amount of sediment the well pump is encountering and that varies. Our well is 475 feet deep and we are in North/Central Massachusetts.

**Q: 0.5 microns or 5.0 microns???   Thought any filter under 5 was not string wound.**
A: This filter (WP.5BB97P) is rated at 0.5 Micron.  It is constructed from polypropylene string that is wound around a rigid polypropylene core.

**Q: Our current Pentair filter is 9 3/4" - will this 10" fit in the housing?**
A: Hi Kathy.  This filter will fit standard 10" Big Blue housings and should fit into most all industry standard Big Blue or heavy duty housings that take the 4" diameter cartridges.
