So which is the better solution? Or should I be looking at car type pleated filters instead?
Here are some pics:

The thin dense foam.

A/C units tend to have more powerful fans than are available or appropriate for a silent PC setup. They also tend not to be very quiet. Using both foams in series will be hideously restrictive and reduce airflow hugely. If I had to choose I'd go with the thinner foam, but really if your dust problem is that bad you should focus on eliminating the source (ie carpets/pets/smoking) or at least keep them out of the immediate vicinity of your PC.Why not both? I notice that a lot of air conditioner filters feature more than one layer. First is the coarse layer, so it can catch big stuff and keep it from prematurely clogging up the finer layer behind it.
