Indoor air quality is getting more and more popular these days, and for very good reason. An average person spends 18 hours a day inside their home and the air that they breath is very critical. A typical ducted system comes with a cheap 1" filter that has a low Merv rating. By adding a 5" filter you can achieve a very good Merv rating which will take out Bactera and Pollin and other pollutants in the air.
Another good option is UV lights. These Uv lights steralize the air and kill Bactera and virus found in your duct work.
