## Overview

The Pentair Pentek EP-20BB is a 20-inch Big Blue carbon block water filter cartridge featuring a 5-micron rating that effectively reduces chlorine taste, odor, and fine sediment. Its high-porosity design ensures maximum carbon utilization with minimal pressure drop, while a polyolefin outer wrap extends cartridge life by trapping sediment. Certified to NSF/ANSI Standard 42, it fits all 20-inch Big Blue housings and delivers up to 44,000 gallons per cartridge. Sold in a convenient 4-pack, it offers a reliable, year-long supply of cleaner, better-tasting water for whole-home filtration systems.

## Description

The Pentair Pentek EP-20BB is a 20-inch Big Blue whole-house carbon block cartridge that reduces chlorine taste and odor and other unwanted tastes and odors for cleaner, better-tasting water. It is molded from bonded powdered activated carbon (PAC) and rated at a nominal 5 microns, so it also captures fine sediment.A high-porosity design keeps water moving through the block as the carbon works, so more of the carbon is used before the cartridge plugs, all at low pressure drop. A polyolefin outer wrap acts as a pre-filter, trapping sediment that would otherwise plug a carbon block and extending the cartridge's useful life.Measuring 20" x 4.5", it fits all 20-inch Pentair Pentek Big Blue and other heavy-duty housings and is tested and certified by NSF International to NSF/ANSI Standard 42 for material requirements. Each cartridge provides up to 44,000 gallons at a low 2 psi drop at 4 gpm and handles water up to 180°F. Ships as a value 4-pack; replace about every 12 months.

Review: Save a lot of money DIY - Water softener plumber wanted 285 to replace this filter each year. Failed to inform me I could do it myself for less than a third the price. Glad my handyman pointed this out this year. Will save me a ton of money paying a plumber to do simple task of changing the filter.
Review: Excellent filter! - I used this filter with a Pentair Big Blue housing as part of my water filtration system. Unfortunately, after plumbing was done and when I took the filter out, I discovered that the blue rim on one end of the filter was broken. The damage was not visible until I removed the filter from its packaging. This is not a defect of the filter itself; rather, desertcart needs to ship these filters more securely, perhaps with bubble wrap or additional protective packaging. Fortunately, desertcart made it easy to request a replacement. The replacement arrived without any defects, but it was still simply placed in a box without much protection, which could easily result in damage during shipping. As for the filter's performance, it has been exceptional. I experienced very little pressure loss—about 2 to 4 PSI at most. The filter is also NSF-certified, which was one of the main reasons I chose to purchase it. Overall, I am very satisfied with the product; my only concern is the inadequate packaging during shipping.
