I bought this filter for my daughters kitchen in her dorm. She didn't want to lug plastic bottles around and she does a lot of cooking so it made sense. It's super easy to know when it's time to replace or if there is an issue with it because the light will change colors. The price is perfect and it makes me feel better as a parent to know my daughter is getting pure water that has all the chemicals taken out of it and she can drink as much as she wants. The filters last a good amount of time and aren't beyond my budget either.
