Review on Enhance Your Water Quality with the ISpring 3 Stage Filtration 20 Inch Sediment System by Allie Hull

In general I am satisfied with the filter system. I installed it in combination with a 50 micron pre-filter and an iSpring UV Sterilizer. I dug a well that could potentially pollute surface water and I am very comfortable drinking tap water. I installed the filter directly into the intake which is a terrible idea. iSpring says you can do it, but it does it so close you can't get the filter key on it. In addition, when the filter is turned down, the thread is very short and it is difficult to fasten it in the filter housing.
