I get about 2 months out of one running at 1 bubble/second, but I use a solenoid so it's only on for 10 hours a day. Run 24/7 at that rate, I'd guesstimate you'd get a bit less than a month out of one.
I love mine and wouldn't hesitate to recommend it to someone, but considering the cost of refills I'd call the solenoid almost a neccessity.
