The best CB filtration
Tara - Carencro, LA (Sunday, January 06, 2013)

I have a dual system and normally order a Carbon block filter as the last filter in line with a 1 micron in front to catch the bulk of the rust. These ones last me about 3 months. I recently tried the other CB's in the $50 range and they each went out after a month. If you have a lot of crap or rust in your water this particular make seems to hold up longer.

This filter does provide outstanding filtration qualities however it is a .5 micron filter and can greatly reduce your flow rate. The spec's don't clearly identify that, so beware.
