For our systems with 10” diameter tanks that include our bacteriostatic carbon filter media, SilverShield® HYgene®, the carbon must be replaced every 112,500 gallons of water used, which for a typical family of 4 is about 12-18 months. Our 8” diameter tanks have a replacement interval of 75,000 gallons, and our 12” diameter tanks have a replacement interval of 150,000 gallons. Our smart iGen® series measures the amount of water that is filtered and informs you when it is time to change the filter media by saying “Call for service” on the display. For our older generation systems, you will need to estimate how often the maintenance needs to be done based on the size of your family and an estimate of your water usage. Our systems that use salt for back flushing need to have the salt replaced periodically. Keep the salt at least half full in the salt tank.
