I have been running this system for a couple of years now in a 2 unit apartment house on city water. Annual consumption with 7 college students is about 66,000 and I still typical only need to change the filters annually. However after 3 months of use the tenants reported loss of pressure. Highly unusual for that short of interval but upon checking the sediment screen found lots of contamination. When I pulled the paper sediment filter I was shocked to see it covered with a gooey layer of rust looking contamination. Turns out the town water lines have been under construction multiple blocks away throughout the fall semester and everything agitated has come into the near by properties. So glad I installed the system and kept all that crap out of the drinking water, water heater and plumbing screens. I am currently shopping for a system for my personal property on well water and will install an iSpring filter here as well. Thanks for a great product. Well done!

We have recently moved into a new community and noticed that the public utility company water taste like chlorine. I am extremely happy with this whole house system. Now I have great-tasting, -smelling, &-felling water from every faucet at home!

Delivered on time and their Youtube video is really helpful in terms of installation. The chlorine smell and taste is gone. 5 stars

Great filter system. I also installed a 50 micron sediment filter before and a UV filter after. There is a noticeable positive difference in the water immediately. 100% satisfied!
