Product review (2 stars): Filter works and fits as advertised. Serious doubts as to its actual filtering abilities.
Filter works and fits my refrigerator, as advertised. However, I strongly doubt that it actually filters as effectively as the OEM filter it is replacing. I have no scientific evidence to back this up, but I have noticed a SIGNIFICANT increase in the water pressure coming out of the refrigerator. This tells me - as it has others - that the water is encountering far less resistance through the filter, thereby suggesting far less filtering.

Also, the filters are described as NSF certified, which is nowhere on the filter itself, unlike other filters.

Bottom line, after less than a month, I replaced this filter with another one I purchased at the Home Depot and the flow difference is striking. In addition, the filter from Home Depot has clear marking referencing the NSF certification. It's also twice the price...
