Product review (4 stars): Great value considering what Brand Names are going for!
Excellent price point to where the brand name filters should be sold as.  Maybe I should give this 5 stars, but honestly it's a water filter and the 5th star should be given by those that can tell the difference in the quality of what it actually filters out.  The technical data for the filter's quality is what I'm not giving the 5th star for as again, I'm not sure on how to rate that other than the water doesn't taste funny or anything unusual to the obvious senses.  Everything else seems perfect and I'd buy this again if available next time we need to replace the filter.  Thanks Waterfall Filter Company! :)
