MY DIY Carbon Filter

Here is are a few pics of my DIY carbon filter. I make the fiter from this thread https://www.rollitup.org/do-yourself/101248-best-diy-ez-walmart-carbon.html . I got a 6" In-Line Duct fan from Home Depot. The total cost of everything is about $50. Couldv'e made it cheaper if I wanted to order some of the stuff. But I'm impatient. Let me know what you think.

looks good, but how is it working?

It's working amazing actually. No smell whatsoever. If I put my hand on the filter it sucks my hand to it. Pretty strong.
