Easy install for clean drinking water Review by Mike S
We live in an area with decomposed granite and some particles are less than the 10 micron filter capacity. The 1 micron filter does a great job, installs easily and at certain times of the year, it is almost a monthly occurrance. But we enjoy clean, clear water in our mountainside home.

Just what I need Review by wellwater
Very hard to find 1 micron filters locally. These are just what I need to clean up our well water and they do a very good job at it. It is almost disgusting to see what they filter out. Even more disgusting to realize we'd drinking that stuff if it were not filtered out. When the filters get dirty enough, they restrict the flow of water so much that I have to change them. That's good. They are doing what they are supposed to do. Coarser filters just let the stuff pass through. That's not good. (Posted on 2/13/15)
