There is no quality 1 inch filter system available.. If you stick with only a one inch filter slot, check with a quality hvac tech to see if your system can handle using a cheap pleated 1 inch filter and change it monthly..
If you are interested in better air quality thru your system then think about a Aprilaire 2200 or 2400 media cleaner or a hybrid electronic as in a Aprilaire 5000 or Carrier Infinity Air Purifier..
My experience with that type of product is that they are VERY restrictive to airflow.
Since they don't provide any airflow performance data, we can't tell what kind of affect that particular product would have on airflow.
The products of any air filter manufacturer that doesn't provide airflow performance data are to be avoided.
If more government is the answer, then it's a really stupid question.
