I always recommend this water filter to my clients. I have researched water filters extensively and this is by far the most affordable option for good clean water. This filter is a stand alone system you can have on your counter top. You fill it up with water from your tap and it mimics the way the earth filters water. This removes an extremely high proportion of fluoride and 100% of chlorine from your drinking water. It also re-mineralises the water which is very important.
