Basically I set this up in about an hour.   I put a foot deep hole in the flower bed and gave the antenna mast a moderate soil base to keep it from moving.  I also used a piece of yellow twine and and two small penny nails to keep it from swaying up top.  I put a V bend in the air filters and sewed a trash bag onto the filters to catch the runoff and flow in back into the sump.  I sewed the vinyl tubing to the air filter in a few spots with yellow twine to keep it from moving around  and cut  pretty small notches in the tubing across the top to turn it into a soaker hose.   It does not need to be a large amount of water, just enough to keep the fabric mesh wet.  Inside air is pulled in with a box fan.  No water has to come in contact with your window sill.   Very few drips make it to the ground, and water loss is kept to a minimum.  One or two  gallons every other day
