Vicks makes great humidifiers. I would have preferred the option to put vicks, or vicks drops into the humidifier but they were out of that model at the time. It is rather small, and needs to be filled up often but is very reliable and emits a lot of moisture into the air.
It is a nice cool moisture that keeps us moist in the winter, when it gets really dry here. The great thing about it is that it's very easy to refill, and is nice and small - a very low profile humidifier. It has a nice large vent in the front for the moisture to come shooting out at you.
The filters are available at the local drugstore, and I like to change them monthly to ensure that the air i fresh that we are breathing in, the humidifier, along with an air purifier has made a great difference in the air that we are breathing in .
This is not a silent humidifier, and sounds like that of a fan - but I wouldn't call it too offensive. On the lower setting it is actually quite low.
