Product review (2 stars): NOT THE SAME!
I bought and installed this filter with no problems and it works as described,  I was so happy to have found a less expensive alternative that was also a green product.  However it does NOT last as long as the manufacturers do!  I just filled a glass with water from my fridge as I always do and I can taste all the chemicals that I taste from the tap.  I now have to buy the manufacturers filters at an additional cost.  Today is April 11,2013 and I will already need to install the 2nd filter until I can order the other ones. These I bought in Jan of 2013.  I recommend that you not waste your money buying these as they last for such a short period of time.  The Matag ones last me almost a year!  These, barely 2 months!  Just want to add that I also live alone so I am the only one using the water from the fridge.
