Product review (5 stars): Amana Water Filters
These filters are available online at a couple of places. Though I feel the price is ridiculous everywhere, I went for the best price and shipping charge deal. I believe I got it on Amazon. Product is the same as others I have purchased. Whether or not you replace them every 6 mos. as recommended I think depends upon your level of usage, i.e., number of people in family. I go around a year with mine before changing. When the water becomes too slow--that's when I change it.
