When it works, this humidifier does a wonderful job. However, at least once a week it goes on strike. Since we first got it my husband has been dutiful in taking it apart and cleaning it thoroughly. Sometimes it decides to start working again, sometimes it doesn't. Sadly, my husband (who is the most laid back human you will ever meet) decided to have it out with humidifier after spending 30 minutes cleaning - only to have it refuse to get back to work. He dropped a punch on it (which makes me laugh now that I think of it) and it's now headed to the humidifier graveyard. Good riddance.
