We have a PUR filter that attaches to the faucet. We had a Brita pitcher for years and when it broke a few months ago, we replaced it with the faucet filter. I really like this so much better. It's fast, and it's great to be able to filter not only our drinking water, but also the water we use in the tea kettle, or boil food in, etc. I also like that it gives us more room in the fridge.
At first I thought it would be in the way but when I don't need it, I just swivel it backwards under faucet and it's out of the way.
Regarding distilled water that another responder mentioned...not a healthy choice for regular drinking water. It might be good for someone with a specific health issue but for the rest of us, the minerals that are in water are good for us and the lack of them leeches those minerals from our bodies, which can lead to all kinds of other health issues.
