Product review (4 stars): The way to cleaner water
My main refrigerator uses MWF filters, so thought I'd give this one a try. It arrived on time and was well packaged. Instructions were clear and I followed them to the letter. I soaked the filter for a number of minutes to activate it, uninstalled my old filter and installed this one. Now the water coming out is clean and clear. Company is US-based, courteous and helpful.
