The filter media is constructed from a blend of resin-impregnated cellulose and polyester fibers, providing higher wet strength than standard cellulose cartridges. The pleated design delivers 36 square feet of filter surface area, extending dirt-holding capacity and filter life compared to non-pleated alternatives. The ECP5-20BB features a sonically welded overlap seam that reduces internal bypass for improved filtration efficiency. The cartridge is built around a polypropylene core for added structural strength, with polypropylene endcaps and gaskets for a secure seal. It is compatible with both chlorinated and non-chlorinated water supplies. This cartridge operates at less than 1 psi pressure drop at 20 gpm, with a temperature range of 40-125 degrees F. The white endcap is color-coded for quick 5-micron identification during filter changes. Replace every 3-6 months or when you notice a decrease in water pressure. ## Features - REDUCES SEDIMENT AND PARTICULATES - Pleated cellulose polyester media captures dirt, sand, silt, and rust down to 5 microns while maintaining high flow rates for whole house water filtration - 36 SQUARE FEET OF FILTER MEDIA - Pleated design provides significantly more surface area than standard cartridges for extended dirt-holding capacity and longer filter life - SONICALLY WELDED FOR EFFICIENCY - Overlap seam is sonically welded to reduce internal bypass and improve filtration efficiency; resin-impregnated fibers provide higher wet strength than regular cellulose - FITS 20" BIG BLUE HOUSINGS - Drop-in replacement for any standard 20" x 4.5" Big Blue or heavy-duty filter housing; white endcap is color-coded for easy micron identification at replacement - LOW PRESSURE DROP - Less than 1 psi at 20 gpm maintains strong water flow throughout your system; operating temperature range 40-125 degrees F; replace every 3-6 months ## Technical Specifications | Specification | Value | |---------------|-------| | Asin | B0030ZJYTK | | Best Sellers Rank | #10,471 in Industrial & Scientific (See Top 100 in Industrial & Scientific) #2 in Industrial Process Filter Cartridges | | Brand Name | Pentek | | Customer Reviews | 4.4 4.4 out of 5 stars (84) 4.4 out of 5 stars | | External Testing Certification | IAPMO, ANSI, NSF | | Global Trade Identification Number | 00051678494431 | | Included Components | Big Blue 20-Inch Sediment Water Filter | | Item Dimensions D X W X H | 4.5"D x 4.5"W x 20"H | | Item Type Name | Big Blue Sediment Water Filter, 20-Inch, Whole House Heavy Duty Pleated Cellulose Polyester Replacement Cartridge, 20" x 4.5", White End-Cap, 5 Micron | | Item Weight | 1.4 pounds | | Manufacturer | Pentair Industries | | Manufacturer Part Number | 255494-43 | | Material Type | Polyester | | Model Number | ECP5-20BB | | Number Of Items | 1 | | Product Benefits | Removes Dust | | Set Name | Big Blue | | Unit Count | 1 Count | | Upc | 182682388345 051678494431 807032972622 | ## Product Details - **External Testing Certification:** IAPMO, ANSI, NSF - **Item Weight:** 1.4 pounds - **Material:** Polyester - **Product Benefits:** Removes Dust - **Product Dimensions:** 4.5"D x 4.5"W x 20"H ## Images ![Pentek ECP5-20BB 255494-43 Big Blue 20-Inch Sediment Water Filter, 4.5" x 20", Pleated Cellulose Polyester Cartridge, White End-Cap, 5 Micron - Image 1](https://m.media-amazon.com/images/I/41SnbohCQhL.jpg) ![Pentek ECP5-20BB 255494-43 Big Blue 20-Inch Sediment Water Filter, 4.5" x 20", Pleated Cellulose Polyester Cartridge, White End-Cap, 5 Micron - Image 2](https://m.media-amazon.com/images/I/81jjLZDEefL.jpg) ![Pentek ECP5-20BB 255494-43 Big Blue 20-Inch Sediment Water Filter, 4.5" x 20", Pleated Cellulose Polyester Cartridge, White End-Cap, 5 Micron - Image 3](https://m.media-amazon.com/images/I/71PE+LGszfL.jpg) ![Pentek ECP5-20BB 255494-43 Big Blue 20-Inch Sediment Water Filter, 4.5" x 20", Pleated Cellulose Polyester Cartridge, White End-Cap, 5 Micron - Image 4](https://m.media-amazon.com/images/I/71ZZBSPbwML.jpg) ![Pentek ECP5-20BB 255494-43 Big Blue 20-Inch Sediment Water Filter, 4.5" x 20", Pleated Cellulose Polyester Cartridge, White End-Cap, 5 Micron - Image 5](https://m.media-amazon.com/images/I/71YvAk0UJJL.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works very well, heats up fast *by on Reviewed in the United States August 21, 2023* This heats a 12x12 3 season room very quickly and doesn't have to constantly run, but that could be because the space is well insulated. Still, very satisfied with this heater. ### ⭐⭐⭐⭐⭐ Great Filter *by on Reviewed in the United States April 30, 2014* Fit wonderfully into my Pentek holder. It was cheaper than buying two filters at my local store. The filter seems to be working great as well. ### ⭐⭐⭐⭐⭐ Fits well, lasts about 2-3 years or more *by on Reviewed in the United States May 13, 2020* Fits well, lasts about 2-3 years or a little more, but do not recommend using it for too long since it could tear and fog could get in. ## Frequently Bought Together - Pentair Pentek ECP5-20BB Big Blue Sediment Water Filter, 20-Inch, Whole House Heavy Duty Pleated Cellulose Polyester Replacement Cartridge, 20" x 4.5", White End-Cap, 5 Micron - Captain O-Ring - Replacement 151122 O-Rings Compatible with Pentair Pentek Big Blue Water Filters OEM Size ORing Buna-N (3 Pack) - Pentair Pentek NCP-20BB Big Blue Carbon Water Filter, 20-Inch, Whole House Non-Cellulose Carbon Impregnated Pleated Filter Cartridge, 20" x 4.5", 10 Micron --- ## 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.jp/products/17161248-pentek-ecp5-20bb-255494-43-big-blue-20-inch-sediment](https://www.desertcart.jp/products/17161248-pentek-ecp5-20bb-255494-43-big-blue-20-inch-sediment) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-08-30*
