Our iSpring whole-house water filtration system WGB21BM and most whole-house systems that use 10" x 4.5" filters can effectively reduce the levels of iron (max 3.0 ppm down to 0.01 ppm) and manganese (max 1.0 ppm down to 0.01 ppm) in the water entering your home, providing you and your loved ones with safe, clean, and healthy water.

Introducing the iSpring FM15B, a powerful iron and manganese reducing filter specifically designed for efficient removal of these harmful substances. This filter can effectively reduce iron (max 3.0 ppm down to 0.01 ppm) and manganese (max 1.0 ppm down to 0.01 ppm), improving water quality and protecting your family's health. It is compatible with the iSpring whole-house water filtration system WGB21BM and most whole-house systems that use 10" x 4.5" filters.

The iSpring FM15B offers exceptional performance, with higher linear velocities than conventional media delivering high flow rates and very low pressure drop. It operates within a feed water pressure range of 20 - 100 psi, with a pressure impact of up to 5 psi drop at a flow rate of 8 GPM and a flow rate of 4 - 8 GPM.

This filter demonstrates excellent stability and durability, with satisfactory performance across a wider pH range of 5.8 - 8.6 and a temperature range of 40 - 113°F. Furthermore, it lasts up to 3 times longer than green sand due to the catalytic media not being consumed in the process, with a filter life of 30,000 gallons at a 3.0 ppm iron level.

Manufactured to comply strictly with FDA standards and tested by independent third parties against NSF/ANSI standards for water quality, material safety, and structural integrity, the iSpring FM15B is a high-quality product you can trust.
