Usually used as the first stage for 20 in. whole house water filters, iSpring FP25B sediment filter is effective in removing dirt, rust and sand particles down to 5 micron. Depending on the inlet water quality or usage, it needs to be replaced every 12 months or 100,000 Gal. of water.
Replacement filters for iSpring whole house filter systems (fits systems WGB32BM and WGB22BM )
Powerful Iron and Manganese Reducing: iSpring FM25B is specially designed for iron and manganese removal, reducing iron (MAX 3.0 ppm down to 0.01 ppm) and manganese (MAX 1.0 ppm down to 0.01 ppm)
Higher linear velocities than conventional media delivers high Flow Rates and very low pressure drop; feed water pressure: 20 - 100 psi
Pressure impact: up to 5 psi drop at a flow rate of 8. gpm; f low Rate: 4 - 8 gpm; the iSpring FM25B effectively removes harmful substances, improves water quality and protects family health
Stable and satisfactory performance at wider pH range 5.8 - 8.6 and temperature range 40 - 113F
Lasts up to 3 times longer than green sand due to the catalytic media not being consumed in the process
Safe for Drinking Water Applications
Manufactured to comply strictly with FDA standards and tested by independent third party against NSF/ANSI standards for water quality, material safety and structural integrity
Unlike an RO membrane, the filters don’t reduce Total Dissolved Solids (TDS), and instead keep healthy minerals in your water; if you are interested in a filter that removes TDS, consider our iSpring Reverse Osmosis (RO) systems
