Very Satisfied
Takes care of sediment from my well. Also I have a slight iron problem. The staining is virtually gone and the taste of the water is very neutral.

Great product
Seems to do a great job and the product was here the next day! No noticeable difference in the water flow. We have bad smelling water also and it takes care of that too!

Difficult to seal
The filter seems to work okay but getting it to seal was a problem. I keep new O-rings on hand but that didn't help. I noticed it uses a fairly hard plastic gasket as opposed to the silicone gasket Culligan uses and is slightly taller filter. It took quite an effort to seal off. They are cheaper than the OEM but not sure I will use again.

Best filters out there
We have bad smelling water. Everything smelled like rotten egg. Until we found these filters. My water is clear, smells great and tastes amazing. I have been using these for 3 years. I change them 2 to 3 times a year and well worth the money.
