I use it and love it. I’m really picky (I guess) about water taste. The filters need to be changed every 2–3 months, (you can start to tell). The filters take the taste up to (just below) R.O. or distilled quality IMHO. Changing the filter isn’t hard, assuming you have the pitcher I have, you soak the new filter in water 10 mins, then drop it in. Run 2 pitchers through it that you dump out to prime it. Then you’re ready to go.
