About This

  • [Great Compatibility] As the official replacement filter set for iSpring whole house water filtration system WGB21BM, this filter pack consists of one 10"x4.5" CTO carbon block filter(FC15B) and one 10"x4.5" iron and manganese reducing water filter(FM15B). Fits standard 10"x4.5” whole house water filtration systems.
  • [Highly Activated Carbon Block CTO Filter] Using high quality coconut shell carbon and highly compact fabrication tech, iSpring CTO filter FC15B 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.
  • [Iron and Manganese Reducing] 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). Together with 1st stage carbon block filter FC15B, this filter meets your water filtration needs to protect your family and household appliances from iron, manganese, and more.
  • [Easy Filter Change] Individually sealed for freshness. Depending on source water quality, replace the filters every 6 months to achieve optimal performance. Please refer to our manual and our helpful YouTube videos for filter change tips if needed.
  • [TDS Note] The system this filter pack works for is installed at the main water supply line in order to treat all the water in your home. Unlike an RO system, this system will NOT reduce Total Dissolved Solids (TDS) and instead keeps healthy minerals in your water. If you are interested in a filter that removes TDS, please consider our iSpring Reverse Osmosis (RO) systems such as RO500, RCC7, RO100 and more.
