Product review (5 stars): Very easy to use and clean
I bought this on another site for $420 shipped but I figured I'd review it here because this is where I always come to check reviews on products.

I have this 200 pint/day IdealAir unit and 2 of the 80 pint/day units.  At first I tried using this 200 pint/day unit with the upper fan attachment and the directional head because the directions didn't say not to and it wasn't putting out nearly as much humidity as the 80 pint/day units so I resorted to using it without the directional head which got the humidity up to levels I needed but also soaked everything above 4 feet in a 6 foot diameter circle surrounding the unit.  I finally decided to try removing the upper fan attachment and replacing the directional head and the unit is working perfectly for me ... it puts out enough humidity to easily keep my 10 x 13 room at 70% RH while keeping everything dry as well.  So, when using the directional head with this unit do not use the upper fan attachment or you will be very disappointed.

Other than the missing info from the manual I have had zero issues with this unit but I've only been using it about a month now.

I tried a diy 10 head ultrasonic humidifier in the same room and while it worked well, and they do have their application, I much prefer these IdealAir units over the ultrasonics as long as the directional head is used as it keeps everything dry.
