Product review (2 stars): Definite quality difference from more expensive filters...
I was swayed by the inexpensive price to try this 3-pack since we had previously used more expensive filters.  We ran well over the recommended 4-5 gallons of water through the filter to flush it out during installation, but the water had an obvious dirty taste.  We continued to use the filter for over a week to see if the taste got any better, but it did not.  We ending up resorting to drinking tap water instead.  Bottom line, the taste may not bother you as much as it did to us, but if you are used to a good filter, you will almost assuredly notice a difference using these.
