## Overview

The iSpring 3-stage whole house water filter replacement pack features sediment, CTO carbon block, and iron & manganese reducing cartridges designed to fit standard 20x4.5" housings. It effectively removes iron (down to 0.01 ppm), manganese, chlorine, rust, pesticides, and VOCs while maintaining healthy minerals. With a high capacity of 100,000 gallons per filter set, it supports a family of four for up to a year, offering easy DIY installation and NSF/ANSI certified quality.

## Description

Used as the first stage of defense on the system, the stage 1 housing holds a 5-micron high-capacity polypropylene sediment filter. This filter removes dirt and other various larger sized particles from the water that can clog the following filters. The second stage of the WGB32BM houses a 5-micron CTO coconut shell carbon block filter. Block carbon is more effective than other forms of carbon in that it is finely ground up carbon packed into a solidified block. This means they have a higher density than other types of carbon filters, and are therefore more effective in removing their targeted contaminants. The carbon block filter knocks out bad tastes and odors, removes up to 95% of chlorine from the water, and is highly effective on organic chemicals (VOCs) like pesticides, herbicides, and industrial chemicals. The third stage of the F3WGB32BM has an iron and manganese reducing filter - also great for the plethora of heavy metals found in well water sources.

Review: Very good filters that take the metal out of our system. When I changed them out they were full of rusty metal. I’m on a tough well and these work very well. I change them out at 6 months. I left them to 8 months which was too long.
Review: This is iSpring, quality is second to none. Excellent product, very pleased, bought a back up set of filters immediately after system install to ensure we are covered in case of supply issues from the USA. Would buy again without second thought. Highly recommended!

## Features

- [Protect Your Family and Household Appliance from Iron, Manganese, and More] Our filter (FM25B) is specially designed for iron & manganese removal, reducing iron (MAX 3. 0 ppm down to 0. 01 ppm) and manganese (MAX 1. 0 ppm down to 0. 01 ppm). It lasts up to 3 times longer than greensand due to the catalytic media not being consumed in the process. The filter set also removes sediment, chlorine, rust, pesticides, herbicides, industrial solvents, VOCs, and various other contaminants.
- [DIY Installation and Maintenance] Refer to our manual and our helpful YouTube videos for easy DIY installation. The 20? x 4. 5? filter cartridges have a minimum impact on water flow (up to 15 GPM) and require minimum maintenance. Our filter set fits standard 20? x 4. 5? housings, including brand name models.
- [Top-Notch Quality] The first stage high capacity polypropylene sediment filter is able to achieve filtration down to 5 micron. The second stage CTO Carbon Block filter is made of high-quality coconut shell carbon for maximum filtration efficiency and filter life. Both are tested by an independent third-party to meet NSF/ANSI standards. Both filters have a capacity of 100, 000 gallons of water, enough to supply a family of four with clean water for a full year.
- [Please Note] The cartridges are individually wrapped to ensure freshness. Please unwrap the cartridges before use. For well/pond water with very high iron/manganese please contact us for customized solutions. Unlike an RO membrane, the filters don?t reduce Total Dissolved Solids (TDS), and instead keeps healthy minerals in your water. If you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems.
- International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
