Designed for 5-micron filtration, it offers 33% more dirt-holding capacity than competitors, fits all standard 20" Big Blue housings, and includes a color-coded white end-cap for easy identification and replacement every six months. Certified by IAPMO, ANSI, and NSF, it ensures high flow rates with minimal pressure drop, making it a trusted choice for clean, sediment-free water throughout your home. ## Description The Pentair Pentek ECP5-20BB is a 5-micron pleated sediment filter cartridge designed for whole house water filtration in standard 20" x 4.5" Big Blue housings. 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. Review: Quality filter for a rainwater filtration system. - I've been using these filters in our whole-house rainwater system that serves as our primary potable water source for 9 years, so I've probably bought them over fifty times. They hold together well and filter the water exactly as they should. As long they make them I'll continue to use them. Review: Good filter for wells - Unlike some comments, the Pentair, Pentek ECP1-20BB 1-Micorn filter does not come packaged with notations not to use with non-chlorinated water. We use it on our well and even with just pressure tank pressure (Less than most city supplied water), it works superbly. Will buy again. PS: We have a professional well company who also recommends this filter. ## 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 | #10,532 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #3 in Industrial Process Filter Cartridges | | Brand | Pentek | | Brand Name | Pentek | | Customer Reviews | 4.7 out of 5 stars 350 Reviews | | 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 | Polyester | | Material Type | Polyester | | Model Number | ECP5-20BB | | Number of Items | 1 | | Product Benefits | Removes Dust | | Product Dimensions | 4.5"D x 4.5"W x 20"H | | Set Name | Big Blue | | UPC | 182682388345 051678494431 807032972622 | | Unit Count | 1.0 Count | ## 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 ### ⭐⭐⭐⭐⭐ Quality filter for a rainwater filtration system. *by S***N on May 30, 2024* I've been using these filters in our whole-house rainwater system that serves as our primary potable water source for 9 years, so I've probably bought them over fifty times.
