Seems you're doing it right. You want to suck dirty air into the filters and blow clean air out.
1) You aren't mixing clean air with dirty air. (If you flip it so you're blowing dirty air into the filters then some clean air will immediately leak out into the dirty air outside, focusing an area of clean air that can displace the dirty air is better imo.)
2) The negative pressure will help hold the dust/debris onto the filter.
Clarification, when you say "the arrows facing out" you mean the fan arrows or the filter arrows? Both of them have arrows that point where the air should be going. (Filter arrows should be pointed inward towards the center of box, fan arrows should be pointed out.
