I was really hoping this would save my iron. It's not like this. My iron did not dissolve. I put in 1 micron instead of the 5 microns that originally came with this kit. It increased my iron from 3ppm to 0.5ppm. This worked for about 2 weeks when we were working part time. Maybe 1000 gallons (I have a water meter). I chose a similar filter from Pentair and then a 0.5 micron carbon filter, also from Pentair. The Pentair installation has now been up for a month and has eliminated the hardware entirely. At 0.5 ppm iron, Pentair is rated for 80,000 gallons. These filters from iSpring lasted about 1000 gallons. Pentair's iron filter is priced similar to the iSpring. Pentair's 0.5 micron carbon filter is quite expensive.
