Hello Patsy! My late friend used to have a Brita filter jug thing, but I'm not sure I'd get one. I read that the filters need changing very frequently, as they grow bacteria in them. I've taken to putting two teabags in the mug to get a decent brew, which I suppose is even more expensive. Another friend has a water softener plumbed in, but my finances don't run to that. My old mum used to say that hard water is good for you. (Don't know if it's true, it might cause kidney stones!)
