We had a reverse osmosis filter put in when I was a kid. In 6 months I ended up with 14 cavities from 0. If you have soft teeth or kids with soft teeth I wouldn't recommend it as it pulls any fluoride out of the water. I live in Calgary now and I know we don't have fluoride in our water but I still wouldn't bother installing one.
