George,
Most of my birds are outside. However. I have a Grey, Lesser Sulfer Crested,
Bronze Wing Pionus and Sun Conure inside. All are, cough...sneeze, molting.
Can't figure out who is under the most stress, them or me.
 GD> I thought all your birds were outside? Need filtering in general, or a
 GD> breeding room? My sister is currently using two 10" fans with furnace
Then, six months out of the year I am handfeeding chicks and when the are 
putting out feathers the dust gets knee deep. My next step is to try the fan 
and filter along with the hepa and my AC.
Ideally, I would like something that vents to the outside. But, I also want 
the benefits of my AC. In Texas you NEED it.
