I'm considering connecting the vents of two bathrooms to the same inline fan.
See my previous question on inline bathroom fans.
Does the fan and the exterior vent grille really need to be above the level of the bathrooms or can they be lower? I have a bath in the basement and one on the main level. I can't go with the fan above the first level for various reasons and it's hard to do it on the first level as well. Would it be a good idea for that inline fan and the exterior grill to be at the level of the basement (between the floors essentially)? This means that the upper bathroom vent pipe will have to go down to that level. Is it a bad idea?

It's not ideal but will probably work.
Hot air rises so the fan would be more efficient if it were in the ceiling or high up on the wall, but even if it's lower down the wall it should be able to remove most of the moist air satisfactorily.
