One of the items I wish to change in my household is the use of plastic water bottles. We buy several cases of bottled water every couple of months but I'd like to curb that and go with some kind of a convenient water filter at the sink. I'm just tired of tossing so many plastic water bottles into the recycle bin.

I don't mind doing the work to tie it into the plumbing under the sink but we'd like to poll the collective here on what's been used and what you like and don't like about whatever system you've used.

We do have a built-in water filter to the refrigerator but the cartridges are pricey to replace every 3-6 months or whatever plus LOML doesn't like the taste.

Thanks!
