## Overview

The Pentair Pentek BBF1-20MB is a 20-inch mixed bed deionization filter cartridge designed for industrial and laboratory-grade water purification. Featuring semiconductor-grade resin, it achieves ultra-low total organic carbon and total dissolved solids, delivering water with resistivity up to 16 megohms. Compatible with all standard 20" Big Blue housings, it offers a high capacity of 1,850 grains, making it a cost-effective and reliable choice for pharmaceutical, cosmetic, and electronics manufacturing applications.

## Description

Pentair Pentek PCF Series Filter Cartridges have been developed in response to the requirements for deionized water in many industries. They are manufactured using resin that has been subjected to additional post-production steps to minimize the total organic carbon (TOC) level. These high-capacity, semi-conductor-grade resin cartridges are ideal for use in pharmaceutical and medical laboratories, cosmetics, and circuit board printing applications. PCF Series Cartridges are available in three sizes, flow rates and capacities. They are convenient and cost-effective for many applications where low levels of total organic carbon (TOC) and total dissolved solids (TDS) are required.

Review: Excellent filters. Should last long - Wanted to upgrade the 10 inch filters to this and I was able to by getting the 20 inch housings and swapping some parts. I go through a lot of DI water at work and needed larger filters. We run our water through a water softener first. Then it goes through a set of GE Merlin RO filters which brings the TDS down to 11 ppm. Then the water goes through 2 of these 20 inch DI filters and then in to a storage tank. Using 3 calibrated TDS meters, we get 0 ppm. The resistivity through some machines is so high, we have to add a hint of tap water back. So it truly is DI water.
Review: Used it for spot free rinse on my cars. - This has worked great as a post free rinse on my cars i purchased solids parts per million counter and my water is around 180 , Once I'm done washing my car i hook up the filter and put the nozzle on a very low flow and rinse the car off "basically spot free rinse" Car comes out spotless This will hold me over until I'm able to purchase the larger spotless system.

### ⭐⭐⭐⭐⭐ Excellent filters. Should last long
*by G***I on January 13, 2024*

### ⭐⭐⭐⭐ Last longer than Previous Brand
*by D***G on October 21, 2019*

I have purchased over 100 of these filters for my employer to filter coolant on a 3000 hp water cooled VFD. They last 2 weeks longer than the previous brand we were using. Typically they last 4 weeks before we need to replace them because the water starts to measure .75 Microsiemens. The water travels through a cooling tower which cuts the life of these filters due to the introduction of copper piping in the flow path. This is a Deionization filter that Deionizes water for mineral free water, if you are using this for a whole house filter it will probably not work well.
