Ventilation and Filter questions for 1000w hps, I'm confused

So I recently bought this (sorry for the quality of the pic)
Its recommended that i have a 400cfm fan to cool this fixture, I also need to scrub my air.... so my question is would it make sense to by this air scrubber with the inline fan built in http://www.amazon.com/LED-Wholesalers-GYO2301-Hydroponic-Scrubber/dp/B003UL8JMM/ref=pd_sim_sbs_ol_1

Or do I need to by an inline fan and filter combo like thishttp://www.amazon.com/LED-Wholesalers-GYO2301-Hydroponic-Scrubber/dp/B003UL8JMM/ref=pd_sim_sbs_ol_1

I just want to hook this up on the light side and vent it through the light and out of the room/box, right? I think the airfilter with the built in fan makes more sense and is cheaper. thanks for any advise or suggestions. stay high!

You'll want the fan and filter to be separate.

Awesome and thank you so mucho Canna! weather you know it or not you have always been a great help to me inderectly!!! thanks bud. Stay high

Always a pleasure. ~grin~ cn

thing is if the fan is pulling air out and there are minor leaks in the connections, smell can escape. The heat from the light could potentially limit the life span of the inline. I'd like to push my air through, though it is not as efficient, for those reasons. However, I like to keep my exhaust separate from my light, just so I can have the exhaust on a timer. Not really sure what you are working with, as the pics aren't uploading for me.
