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: Works very well, heats up fast - 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. Review: Great Filter - 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. ## 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 | B0BF4K8PRY | | Best Sellers Rank | #186,477 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #1,250 in Replacement Under-Sink Water Filters | | Brand | Pentek | | Brand Name | Pentek | | Customer Reviews | 4.4 out of 5 stars 84 Reviews | | External Testing Certification | NSF | | Global Trade Identification Number | 30051678494432 | | Item Dimensions D x W x H | 4.5"D x 4.5"W x 20"H | | Item Highlight | Pleated Cellulose-Polyester, 5 Micron, Reduces Dirt, Sand, Silt, and Rust, 36 Square Feet of Media | | Item Type Name | Big Blue Sediment Water Filter, 20-Inch | | Item Weight | 10 pounds | | Manufacturer | Pentair | | Manufacturer Part Number | 255494-43-APC | | Material | Pleated Cellulose Polyester | | Material Type | Pleated Cellulose 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 | 6 | | Unit Count | 6 Count | ## Product Details - **External Testing Certification:** NSF - **Item Weight:** 10 Pounds - **Material:** Pleated Cellulose Polyester - **Product Benefits:** Removes Dust - **Product Dimensions:** 4.5"D x 4.5"W x 20"H ## Images ![Pentair Pentek ECP5-20BB 20" x 4.5" Sediment Water Filter, Pack of 6 - Image 1](https://m.media-amazon.com/images/I/71GDkFFKw-L.jpg) ![Pentair Pentek ECP5-20BB 20" x 4.5" Sediment Water Filter, Pack of 6 - Image 2](https://m.media-amazon.com/images/I/417kS2hHcaL.jpg) ![Pentair Pentek ECP5-20BB 20" x 4.5" Sediment Water Filter, Pack of 6 - Image 3](https://m.media-amazon.com/images/I/81jjLZDEefL.jpg) ![Pentair Pentek ECP5-20BB 20" x 4.5" Sediment Water Filter, Pack of 6 - Image 4](https://m.media-amazon.com/images/I/71PE+LGszfL.jpg) ![Pentair Pentek ECP5-20BB 20" x 4.5" Sediment Water Filter, Pack of 6 - Image 5](https://m.media-amazon.com/images/I/71ZZBSPbwML.jpg) ## Available Options This product comes in different **Size, Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works very well, heats up fast *by A***G on 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.
