Sized 4.5" x 20", it fits Pentair BPHE-410 and BPHE-420 housings, supports high solids loading for longer use, and withstands fluids up to 200°F, making it a robust and reliable choice for professional-grade water filtration. ## Description The Pentair Pentek BP-420-1 is a replacement filter bag from the BP Series, built for high dirt-holding sediment filtration in bag filter housings. It is made from glazed polypropylene felt, a media chosen for its high solids-loading capacity compared with similar mesh fabrics, so it captures a heavy load of dirt, sand, silt, and debris while supporting faster bag change-outs. The 1 micron rating makes it well suited to applications that call for fine particle reduction and cleaner water.The glazed finish is created by melting the outermost surface fibers, forming a secure bond that reduces the possibility of fiber migration into the filtered stream. Polypropylene felt also offers broad chemical compatibility, making the bag suitable for use with acids, alkalis, corrosive fluids, oils, and organic solvents. The bag is rated for fluids up to 200 degrees F (93.3 degrees C).This bag measures 4" x 18" (102 mm x 457 mm), the 420 size, and is designed to fit Pentair BPHE-410 and BPHE-420 bag filter housings for a simple drop-in replacement. Replace the bag when you notice a drop in flow or a rise in pressure across the housing; bag life varies with incoming water quality. ## Features - CAPTURES SEDIMENT, DIRT, AND DEBRIS - This 1 micron polypropylene felt bag traps fine particles to help deliver cleaner water and helps protect downstream plumbing, appliances, and filters in a wide range of bag filtration systems - HIGH SOLIDS-HOLDING FELT MEDIA - Manufactured from polypropylene felt for high solids loading versus similar mesh fabrics, so the bag holds a heavy load of particles and allows faster change-outs and higher productivity - GLAZED POLYPROPYLENE CONSTRUCTION - A glazed finish formed by melting the outer surface fibers creates a secure bond that reduces the possibility of fiber migration, and offers broad chemical compatibility with acids, alkalis, oils, and organic solvents - FITS BPHE-410 AND BPHE-420 HOUSINGS - Sized 4" x 18" (102 mm x 457 mm), the 420 size, this bag is designed to fit Pentair BPHE-410 and BPHE-420 filter bag housings for a fast drop-in replacement - RATED TO 200 DEGREES F AND 1 MICRON - Withstands fluids up to 200 degrees F (93.3 degrees C); replace when you notice a drop in flow or a rise in pressure across the housing, as bag life depends on incoming water quality ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0067GPSP8 | | Best Sellers Rank | #2,276,584 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #13,672 in Water Purifier Accessories | | Country of Origin | USA | | Item Dimensions LxWxH | 10.2 x 45.7 x 10.2 Centimeters | | Item Weight | 86.2 g | | Item model number | BP-420-1 | | Net Quantity | 1 Count | ## Images ![pentek Bag Filter, 155384, BP-420-1 Polypropylene 1 Micron, 4.5" x 20", White - Image 1](https://m.media-amazon.com/images/I/61sMmcOOO0L.jpg) ## Questions & Answers **Q: Is this fit for 2 inches pipe for water filteration just to hold the dust coming from water** A: You cannot fit directly to the pipe.
