I have a space heater in my room that makes more noise than a hepa filter and my girls seem to do just fine with it....and unlike the hepa filter, my heater is not constant since it is on a thermostat. i think they will get used to the constant noise much quicker than a case like mine.
On a side note, i am a hvac installer and was wondering if you have checked into a system called Clean Effects? You can get it from any Trane contractor and it attaches to your current central heat and air system to provide electrostatic air filtration for the entire house. If you have the HEPA filter for your sons alergies then i am sure you will see a great benefit from having the entire house filtered.
