Someone posted something about a countertop water filter on here a while back. I have been searching the forum for a little while now and can't find that post. It was a filter that used sand, stones, charcoal and other things to filter out the nasties, particularly fluoride. It was a little pricey and so it fell off my radar. I drink water all day and my fridge filter doesn't really cut it. I don't remember what forum sub-heading it was in. I thought I'd ask in "The water cooler" forum and see if anyone remembers.
