I've been thinking about how to install a unit, so the core is sitting with
the (filtered) outdoor-air-input (carrying the moist air) at the best angle.

I would want the (moist) air coming into the top of the core, so it will
have gravity (and air pressure) helping push the water droplets down and out of the core.
(Into a drain pan with a hose on the bottom).

The longer water is allowed to sit in those passages, the more likely
that water is going to collect airborne dust particles, pollen & etc.

Once a water droplet filled with particles evaporates, the residue
left from the contaminates can build up and be difficult to remove..

The dew point temperature have been so high these last few weeks,
anything that is cold is instantly wet when left out..

Instead of making more holes in my house, I've been thinking of building
my unit like a window AC. (Custom sized for my windows).
So, it could be installed easily and easily pulled out to be tweaked or cleaned.
The drain hose would just water the flowers below the window..

I like the idea, but how am I going to get that good drain angle with a window rig?? Humm...
