Air O Swiss Ultrasonic Humidifier 7135

I got the Air O Swiss Ultrasonic humidifier almost 6 months ago during winter. My lips were so chapped they hurt all the time before I started using the humidifier. I use it in my bedroom, which is luckily near the living room, so the humidity goes out there too. I was running it 24/7 during the really dry months. Not as much now. It worked great the whole time.

I love that it is so quiet, since I am a light sleeper. The fan noise is just a hum. It probably would be less noisy if there wasn't a fan, but I wanted one as I think it helps humidify the room. It is pretty easy to refill. It was a little tricky to figure out how to put it together initially. I like the warm mist option. I used that when it was really cold, but don't need it now, so I use the cool mist option and save energy.
I did want to mention that I soak the filter in vinegar every month or so and this increases the humidity output nicely.
The only thing I wish were different is that I did have to refill the humidifier about every 12 hours when running it non-stop and a 24 hour refill would have been nice. But, then again the tank would have been heavier for refills?!
