20" PH Filter
My waters PH was at 4 and this filter brought it to 7 neutral. The copper pipe staining in the shower is gone. This is the second one I've installed and the first one lasted 6 months. I have a deep water well in the country and have a bad iron problem. I have to replace the iron filter every 3 months and this PH filer every 6 months. Works great.

Good Filter
The filter raised my PH level. Could use a little more corosex for a better PH Level raise. Will buy again!
