This water filter removes Fluorine and Chlorine from the water to make the water suitable for baby food and increase taste.
New $189 on amazon (bought 10 months ago, receipt still available).
The filters are still fine but can also be replaced for $30.

Selling it because we moved and a similar system is already installed at our new place.

Additionally removes "arsenic, lead, perchlorate, chromium, copper, TDS (total dissolved solids), sodium, and a long list of other water contaminants like parasytic cysts, such as giardia and cryptosporidia".
