Our fridge has a water source and filter and had to be changed every 2-3 months at the West Valley house. Although we had used our fridge at first house we lived in upon arriving in Oregon, we had never hooked up water dispenser. I have also noticed - even without Wen (which my hair has not seen for over a year now) that my hair is softer than it ever was in Salt Lake. My scalp is also not as itchy.
Another plus in Oregon vs. Utah.
