Not a scientific test, but I was installing a dry chem system in a paint
booth. In the dumpster was some used filter media. I was wondering about
the flammability, so I got a match, with the thought of touching the match
to the used filters. Then I had a better idea, take a piece of the filter
and put in on the ground, then put the match to it. Wow! That stuff burns
quick! So, I do not think placement of the sprinkler heads above the intake
plenum filters would hinder the spray pattern. Having said that, we do not
put the dry chem nozzles above the filters, but below.

If the filters are clogged-or-saturated to point of needing changing,
then these filters might retain heat and smoke, so sidewalls could work.
If the filters are new, or can burn through, then heat and smoke might
flow virtually unobstructed to the ceiling, where ceiling sprinkler spray
would flow down through the filters, or what was left of them.
