About This
- Product 1: [Two-Stage Effective Filtration] Our featured 2nd stage filter (FM15B) 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). Using high quality coconut shell carbon and highly compact fabrication tech, 1st-stage CTO filter(FC15B) knocks out cloudiness as well as bad tastes and odors, removes over 90% of chlorine, and is highly effective on VOCs like herbicides and industrial solvents. iSpring WGB21BM is THE system you need to protect your family and household appliance from iron, manganese, and more.
- Product 1: [Easy Installation and Filter Change] The system comes pre-assembled onto the mounting bracket for a streamlined, DIY installation. Filter wrench included to make routine filter changes easy and quick. Refer to our manual and our helpful YouTube videos to install this point-of-entry (POE) filtration system at the main water supply to get clean and healthy water for the entire family. With 1” NPT inlet/outlet and 10” x 4.5” filter cartridges, the system has a minimum impact on water flow (up to 15 GPM) and requires minimum maintenance.
- Product 1: [Top-Notch Quality] The first stage CTO Carbon Block filter is made of high-quality coconut shell carbon for maximum filtration efficiency and filter life. It is tested by an independent third-party to meet NSF/ANSI standards. The iron and manganese reducing filter lasts up to 3 times longer than greensand due to the catalytic media not being consumed in the process. Those filters have a filtration capacity of up to 50,000 gallons of water, enough to supply a family of four with clean water for up to a year.
- Product 1: [Peace-of Mind Customer Service] Backed by a 30-day money-back guarantee, 1-year warranty, and extended manufacturer warranty upon warranty registration at iSpring. Lifetime CS and tech support from Atlanta, GA USA. We stand behind our products. If you encounter any problems with any of our products, please reach out to us immediately. We are happy to help!

Free of surfactants, binders, and adhesives. No leaching carbon ash.
- Product 2: [Exceptional Filtration Performance] Knocks out cloudiness as well as bad tastes and odors, removes up to 99% of chlorine, and is highly effective on Organic Compounds like herbicides, and industrial solvents and other contaminants like trihalomethanes. Steady flow and high absorption.
- Product 2: [Long Filter Life] Filters up to 50,000 gallons depending on the use and feed water quality. Replace the filter every 6 months or every 50,000 gallons of water for optimal performance.
