Yep. I'd like to consider myself an expert. I suffered from horrible nosebleeds 2-5 times a day due to the dry Los Angeles air. At the doctor's recommendation, I bought a Vicks humidifier, but it made a whooshing noise that was just too loud and obtrusive to sleep with. I then started purchasing every different kind of humidifier, and they were all badly designed, hard to fill, or too noisy. I saw this on a demo at a neighborhood Do It Center, and immediately knew it was special. It produces a flow of fog (like a Halloween fog machine, but evaporates instantly) and is as silent as they get. I have owned it now for 4-5 years and use it all night, every night. The tank also lasts at least 3 nights of running at half power. The only issue I found with it is that it gathered a scaly buildup of minerals from the extremely hard tap water I put into it. A bottle of CLR and a scrub brush fixes the problem once a year. I came back to the website to buy another one for my college dorm. Thanks for making a great product!
