Which system is better?

Question

What make this reverse osmosis http://cgi.ebay.com/5-stage-50GPD-Reverse-Osmosis-RO-Water-Filter-Luxury_W0QQitemZ120279224679QQihZ002QQcategoryZ20684QQssPageNameZWDVWQQrdZ1QQcmdZViewItem

and is it really worth buying the more expensive one?

Answer 1

In my opinion they are both equally useless. Unless your water is so bad that you have to boil it, filtering will only change the taste. Water filters are one of the big cons of the Western World!!!
