## Description

iSpring F3WGB32BPB 4.5” x 20” 3-Stage Whole House Water Filter Replacement Pack Set with Sediment, Carbon Block, and Lead Reducing Cartridges, Fits WGB32B-PB

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

- U.S.-Made Lead-Reducing Water Filter: Our American-made lead water filter (FCRC25B) is specifically engineered to reduce lead levels. This high-capacity whole house filter provides up to 150,000 gallons of filtration at 100 ppb lead levels. The F3WGB32BPB system also effectively removes sediment, chlorine, rust, herbicides, industrial solvents, and a wide range of other contaminants for cleaner, safer water throughout your home.
- Standard-Sized Whole House Filter: Our water filter set is designed to fit standard housings that use 20" x 4.5" whole house water filter cartridges, compatible with many popular brand models. These cartridges maintain strong water flow (up to 15 GPM) while requiring minimal maintenance, providing a reliable and efficient filtration solution for your home.
- Premium Whole House Water Filtration: The first-stage high-capacity polypropylene sediment filter captures particles as small as 5 microns, while the second-stage carbon block filter, made from high-quality coconut shell carbon, maximizes filtration efficiency and longevity. Both filters are independently tested to meet NSF/ANSI standards, with a combined capacity of 100,000 gallons—enough to provide a family of four with clean, filtered water for a full year.
- U.S.-Based Customer Service: Register online to activate your manufacturer warranty and enjoy lifetime free technical support from our dedicated U.S. support team. We stand behind the quality of our products—if you experience any issues, don’t hesitate to contact us. We're always here and happy to assist!
- Important Note: Each whole house water filter replacement cartridge is individually wrapped to maintain freshness—please be sure to unwrap them before use. Unlike reverse osmosis (RO) systems, these filters do not reduce Total Dissolved Solids (TDS), but instead preserve beneficial minerals in your water. If TDS removal is a priority, we recommend exploring our iSpring Reverse Osmosis systems.
