I found this, ordered it, it's on its way. Hoping it really works well. Too bad I can't afford a full house filter like this. It seems to be the least expensive. I've looked at other vendors, found the same thing for $50+ more. It says it has long lasting filters. I don't know what long lasting means. I think the fluoride filter lasts a couple of years. The other filter (dual cannister) probably last a year.
