ETA: The reason this one works for the whole house is that it is big. Follow the link for exact dimensions, but my guess is about 4 cubic feet.
This is the model I bought
It was much cheaper at Homedepot, but seems to be out of stock at the moment.

Other than using an “F” to show the tank is empty I have no complaints about it. The auto mode can keep the whole house at 40-45% humidity when it would have been 10-20% without it. The tank is large enough that I fill it every 1-2 days.
The fan makes noise, but 
that’s how these things work. It doesn’t run continuously, so it’s only intermittently annoying. It is possible to force it to only run at the lowest fan speed, but I just let it run in auto, where it will run the fan faster the farther away it is from the set point.
The white film from the ultrasonic ones is also in the air, and made my PM2.5 and PM10 air quality meter go crazy. This one captures all that in the filter, which I’m sure will be disgusting whenever it is time to change it.
