use a car air filter as a prefilter on my RK05's ,it has a large surface

I have two RL02 drives and a single RL01, and am
interested in buying at
least a couple of these filters. However, I've never changed the
absolute
filters in the drives. Is this something that needs to be done in a very
low particulate environment?
No but make sure the dirt is not left behind so that it can get past the
filter.
RL02 PACKS are not hermetic or even closed to the environment so its not
like a modern HDA and the head flying distances are far greater.
Also, unlike the foam prefilters which
deteriorate over time, I'm assuming that the absolute filters (being more
like an A/C filter?) would stay pretty much intact, even though they are
likely quite old NOS?
The prefilter is to keep chunks out and most anything will do.

Thanks for helping a relative newbie :-)
