Product review (5 stars): Great bargain for extreme filtering
There are so many filters available.  When you read the fine print, most are just ANSI 42 rated, which treats just taste and odor.  And that is what most people buy because they don't read the fine print and are looking for the lowest cost product.  There are a small handful of ANSI 53 rated filters, LG being one of them.  This is even better with ANSI 53 + 401 to filter BPA and pharmaceuticals, and you can get 3 for less than the price of 1 LG.  I hated paying that premium for the LG filters to get the 53 rating, so now I'm excited to be getting these.  The company appears to specialize in water, so I hope it is all legitimate.  Obviously, there is not any practical way for me to test the claims, and judging just based on taste is hardly a test.
