It has a nominal filtration rating of 25 microns at an efficiency of 85%. This filter is made of two polypropylene felt layers on a supporting scrim with thermal glazing of the outer surface for high solids loading capacity and reduced fiber migration. Polypropylene fibers are compatible with a broad range of corrosive fluids, including organic solvents, oils, acids, and alkalis. The filter has a maximum flow rate of 20 gallons per minute (gpm), and operates at temperatures up to 200 degrees F (93.3 degrees C). This felt polypropylene filter bag is used for treatment of residential and commercial drinking water and industrial fluids.SpecificationsCompatible bag vesselsPentek PBH-410-1, PBH-410-1.5Nominal filtration rating25 micronsMaximum flow rate20 gpmMaximum temperature200 degrees F (93.3 degrees C)Maximum dimensions (H x W)8-5/8 x 4 inches (218 x 102 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.What’s in the Box?20 BP-410-25 filter bags ## Features - Reduces sand, silt, scale, and rust particles in residential and commercial drinking water and industrial fluid applications - Nominal filtration rating of 25 microns - Glazed polypropylene felt layers on a supporting scrim for high solids loading capacity and reduced fiber migration - Maximum flow rate of 20 gpm - Maximum temperature of 200 degrees F (93.3 degrees C) ## Images ![Pentek BP-410-25 Polypropylene Felt Filter Bag, 8-5/8" x 4", 25 Microns, Pack of 20 - Image 1](https://images-na.ssl-images-amazon.com/images/I/519pqyF0g2L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Value! *by M***E on Reviewed in the United States on December 30, 2018* Worked great as a way to buy inexpensive replacement filters for my well. ### ⭐⭐⭐⭐⭐ Five Stars *by A***R on Reviewed in the United States on July 8, 2016* Just what we needed ### ⭐⭐⭐⭐ Four Stars *by A***R on Reviewed in the United States on January 8, 2017* Worked perfectly --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/86500578-pentek-bp-410-25-polypropylene-felt-filter-bag-8-5](https://www.desertcart.pl/products/86500578-pentek-bp-410-25-polypropylene-felt-filter-bag-8-5) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-28*
