I did the pot on the stove for a few years, never saw a difference.
Bought many $20 humidifiers (3-4 a year for 2 + years), and no difference, just blew through a lot of them.
The entire time I was doing this, I kept going back to one of these, but never purchasing one because I kept telling myself that it was to much money, blah, blah, blah. That's when I said enough, and bit the bullet. Considering what I spent on the $20 ones, it was a no brainer.

Works like a charm. Fill it every 2-3 days (I keep a couple of water cooler jugs ready for refilling), and my sinuses thank me
