Generally not.  To get rid of fluoride you need a filter which does ion
exchange, or else distil.  Reverse osmosis also gets rid of some
fluoride, though I'm not sure what fraction.  The general rule with
water filter setups is use the carbon or charcoal fiter LAST in any set
up.  However, frequently it isn't enough by itself, if you want the
purest water.
