Here is my system for aerating wort, i use a wine degasser (from Marcello's) with a aquarium pump with the air run thru a filter and valve assembly to isolate the filter when not in use. this system keeps the carboy at a positive pressure so hopefully no bacteria can float in. and I Use a 3/8 drill to run the wine degasser. Notice the blue bottle filled with Isopropyl alcohol for sanitising all connections
and the final product aerated wort, though a sugestion add your yeast before aerating

Where did that filter come from? Doesn't look like the ones I have from morebeer. Interesting method however. Seems to have solved my prior concerns with unfiltered air. Presumably the pump is providing positive air pressure in the bottle, so air is blowing out around the metal shaft.

As a note to others, always make sure that you use 70% isopropyl alcohol. While its generally not entirely understood what mechanism of alcohol is actually performing the sanitization, one popular theory is by denaturing the cell proteins. Proteins are not denatured readily in the absence of water, so 70% is considered better than 90% or 100% at sanitization.

Your mileage may vary. Alternately, you could just fill it up with vodka, and alternate between sanitization, and misting yourself.
