All-Filters CP-6005 Cut to Fit Carbon Pad for Air Purifiers

could anyone tell me the thickness of these carbon pads?

Would this work for a window air-conditioner? Thanks for all the great, albeit contradictory (hehe) answers. Bought it, figuring I can use it for my vacuum cleaner and car's cabin air filter as well. Based on all the answers, I'm thinking it can work with the AC unit as a pre-filter before a regular AC foam filter.

For a whole-house air conditioner system w/ a 3M a.c. filter, do I just place a cut piece of this over the air intake to increase cleanliness of air?

What is the thickness of the Pre-Filter???
