Nice write up.

Don't forget the FFU (Fan Filter Unit) which is all the rage these days. Close to a hood just without the hood part. Lots of people use it with success.

12" thick filters are not preferred at all, they are half the static pressure of the 5-7/8" (at the same airflow/speed) because there is twice as much surface area in the "W" shaped accordion fold that makes up the filter...More surface area equals less resistance.

The reason many used them is because they are much more commonly available because they are used in air scrubber filters and such. You can (or used to be able to) find 12" thick 24x24 filters for around $100 or so on amazon etc pretty easily because they are very common for air scrubbers used in commercial applications.

You may read the specs and see that 1.0" static pressure but you are missing the tested speed or CFM which is very high, they are designed for high volume (i.e. speed) filtration. The pressure drop of a filter changes as the airflow changes. More airflow more pressure. See my signature link.
