Went that route for a while but the costs kept going up and after a while the big plastic jugs are just a pain.

Bought a 5 stage reverse osmosis system from SAMs club like 6 years ago for a few hundred and have never looked back. Every night I just fill up the jugs I take to work with me that I drink throughout the day (1.25 gals).

We also use it for all of our cooking and even ran a line to our refrigerator ice maker. Best tasting clean water ever. Love it.

Recently added an inline mineral unit (puts the good minerals back in).

We have a well now but we also used it when we had the chlorinated city water.
