Its glazed finish enhances chemical resistance and prevents fiber shedding, while its robust solids-holding capacity ensures longer service life and fewer replacements. Compatible with Pentair BPHE-410 and BPHE-420 housings, it withstands fluids up to 200Β°F, making it a reliable choice for both industrial and home water filtration systems. ## 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 | #47,842 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #2,067 in Pumps & Plumbing Equipment | | Customer Reviews | 4.4 4.4 out of 5 stars (330) | | Date First Available | February 19, 2008 | | Is Discontinued By Manufacturer | No | | Item Weight | 3.04 ounces | | Item model number | BP-420-1 | | Manufacturer | Pentek | | Product Dimensions | 4 x 18 x 4 inches | ## Images ![Bag Filter, 155384, BP-420-1 Polypropylene 1 Micron, 4.5" x 20" - Image 1](https://m.media-amazon.com/images/I/61sMmcOOO0L.jpg) ## Questions & Answers **Q: Has anybody tried using this with a Venturi style pool vacuum? If so, how well did it work?** A: I found that these bags work every bit as well as the more expensive ones that our plumbing sub sold us. I will definitely reorder them. **Q: if you pour water into this how long does it take to drain with just gravity?** A: Don't know, we pump the water thru it with a pump. I think it would flow right it, with just gravity. A great filter. **Q: Is this bag "food grade"** A: Yes it is by definition of β€œFood Grade” **Q: Can this be used to filter cold brew coffee?** A: Not sure. Its ised to filter sediments from water so I'm mot sire why not. But I would think it is for cold water only. ## Frequently Bought Together - Bag Filter, 155384, BP-420-1 Polypropylene 1 Micron, 4.5" x 20" - Captain O-Ring - Replacement 151122 O-Rings Compatible with Pentair Pentek Big Blue Water Filters OEM Size ORing Buna-N (3 Pack) - Pentek BP-420-5 Polypropylene Bag Filter --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ph/products/21569282-bag-filter-155384-bp-420-1-polypropylene-1-micron-4](https://www.desertcart.ph/products/21569282-bag-filter-155384-bp-420-1-polypropylene-1-micron-4) --- *Product available on Desertcart Philippines* *Store origin: PH* *Last updated: 2026-07-21*
