Product review (1 stars): Don't waste your time or money.  Get something different.
I got this filter for my fridge as a back up as I already have a Whole House water purification system.  The water that comes out of my faucets is the same as the water that comes out of my filtered fridge, just not cold.  Well after about a month of use, this filter just stopped working.  I have pulled it out and have had no issues with the water from the fridge.
