Product review (4 stars): Not too bad, cheaper than original
These work and are cheaper then the original, so those are two pluses.  I do know they don't filer out and much as the original one (they don't filter down to the microscopic level the original does) but I am not afraid of getting viruses from my tap water. I want the filter to filter out the chlorine smell and take the hard water minerals out,  which this does.  Your water will flow faster too, which is another plus.  If you brush your teeth with tap water, drink the tap water in the bathroom, or otherwise let your kids bath in it where they get bath water in their mouths, then why worry about filtering your tap to contain nothing?  Our water in America is some of the safest and cleanest and best tasting in the world.  Nothing to worry about folks.
