Is it okay to run a HEPA cleaner without the carbon filter installed?

The activated carbon gives off a noticeable smell and since I don't smoke or have any chemical exposures (I'm using the cleaner mainly for the HEPA/particulate filtration), is it okay for me to run it without the activated carbon filter? The cleaner already has a separate prefilter and HEPA filter, but are there any concerns to using the air cleaner in a mode whereby the fan/blower is exposed to LESS incoming air resistance than it was designed for? Any way of damaging the motor or equipment by doing this?
