  • Excellent filtration
We started getting clay & sand in our water well. 40 micron filter was allowing solids into our home so we went with this 5 micron filter. Seal is excellent and zero solids passing through.

  • Love it
We have been using this filter and it works great and last to use over and over.

  • Saves up big time!
We have a community well... good water, but chlorinated and has a bit of a sulfur smell. Also, the tank is an old steal tank, which gives us some rust now and then. We were about to invest in a filter system costing thousands... decided to try the AO Smith whole house system, with this 5 micron carbon filter. Works great! The housing is clear, so I can tell if the filter is getting dirty. If I start noticing the sulfur smell, I will go ahead and change it (usually about 3 months). Tip: Tee off the outside faucets BEFORE the filter if you can. ... show more

  • Water is better
Pressure seems to be unaffected. There is no longer a taste to the water. There is no residue in the shower. Hopefully hit will last a few new months.
