The ongoing cost per year for filters is about 80 and the company inform you when you need to change the filters. The equipment is housed in the cupboard under the kitchen sink with an extra tap alongside the taps at the sink. We use it for all cooking and drinking and regard it as one of our best investments as for the past ten years we have drunk our water with confidence and no smells of chlorine and if water is fluoridated we would at least be able to drink fluoride free water in our home. Regards, Liz Vaughan. The issue is not just fluoride - water hardness is detrimental too.
Calcium salts are always bad news in water.
That leaves the choice between distillation and reverse osmosis. The Doulton Fl-2 pod doesn't come close, from the description below. Distillation is a cheaper outlay but costlier to run and leaves the water way too pure and rather distasteful. You have to dispose of the residue safely, which can contain up to 50ppm fluoride. In very hard water areas you'd have to descale the residue reservoir regularly.
