Ask a Question
  • We have a lot of iron & Zinc in our water. It stains the toilets & sinks. We are currently using a whole house three filter system. First is sediment filter, second activated charcoal & the third is KDF. We have to change them every 2-3 months. Are there better filters to use or a better system you would recommend?

    AF-6003 is not right for iron and zinc removal. Better system is AF-6002:

    The service time for the different cartridges is:

    Filter Name Filter Life
    Sediment Filter Cartridge 6-8 months
    KDF + GAC Filter Cartridge 1 year
    Carbon Block Filter Cartridge 6-8 months
