We have a well, and our water has a bit of brown tint to it due to the sediment. This filter cleared it right up, and our water is now as clear as bottled water. Installation was time consuming, but not really difficult. I’m sure some of the other brands are similar in functionality, but this one was less expensive, making it a better value.

Really cleans up our well water.

The orange filter in the picture is originally white in color, it is full of iron bacteria in our well. Tested water shows no bacteria. Did mount the filter to the wall with an extra spacer. Water does taste a little strange, could just be me.

Great filter

worked as advertised
