Product review (1 stars): Don't Skimp with your water.  Avoid chemicals!
If you're trying to save money this is not the way to do it.  This is a complete waste.  2/4 of the filters did not at all filter the water, the OEM filter that was 'done for' was still actually filtering the water far better than these.  You will quickly prefer the taste of tap water after a couple days of using these filters.

I'd say the best use for these is a gag gift, or just a prank in general.  I couldn't even drink the water without gagging.  I later purchased the OEM LG brand from Amazon and still same result even after about 10 gallons had been ran through.  One review stated this is only occurring with Amazon purchased filters.  Will be taking a trip to Home Depot or Lowes for my next filter soon.
