Try a Britta filter, it really makes a difference
Tastes much much worse in my opinion! I know it's almost defintely better for me but filtered and bottled water is not as nice as the tap water to my taste buds.
The filter/cooler tap we have at work is just awful, I can't drink a glass of that whereas I can drink litres of tap water with ease.
