Quality filter for a rainwater filtration system.
I've been using these filters in our whole-house rainwater system that serves as our primary potable water source for 9 years, so I've probably bought them over fifty times. They hold together well and filter the water exactly as they should. As long they make them I'll continue to use them.

Good filter for wells
Unlike some comments, the Pentair, Pentek ECP1-20BB 1-Micorn filter does not come packaged with notations not to use with non-chlorinated water. We use it on our well and even with just pressure tank pressure (Less than most city supplied water), it works superbly. Will buy again. PS: We have a professional well company who also recommends this filter.

Great Product
Filters fit great in the housing and after checking on them after 30 days of use, they seem to be stopping all of the sediment as intended.
