Thanks for the reply mateyou are correct. it could be that the fan is pulling air too fast through the filter. or that the filter is low quality, or depleted. but giving OP the benefit of the doubt it could also be that he has set it up properly but just has very, very, very smelly plants.
he says he has no windows in his garage so exhaust is not really an option. i see a scrubber as his only option really.
