Carbon media and KDF55 needs to be replace every 5-7 years depending on water usage or every 1,000,000 gallons.
Resin (Salt based water softener) will need to be replaced every 10-12 years. If you have carbon filtration prior to the softener this will drastically expand the years of replacement to 12-20 years. If your water softener doesn’t put out any soft water or it regenerates and runs out of soft water quickly (in just a day or so), you probably have a damaged “resin bed” and it is time to replace.
The effective average lifespan of FILTERSORB SP3 (Salt free conditioning) is 3 to 5 years, depending on the feed water conditions. Can double lifespan with Whole House Filtration prior to salt free filtration.
