I had a water leak for a few weeks and the hard water well added too much calcium to the filter. Got the calcium deposit on the toilet and water spigot cleaned upend put another on filter in early January and it's still working well. Guess I'll have to put an RO system on the well to get much better results but for now it's much better than any GE product I've used in the past
We typically get a lot of mica in our system and this is doing a fantastic job of capturing the mica. I have used the string based filters in the past and this is working much better.
It was exactly as described
Received in a timely manner and they work great. Will purchase again.
