I bought just what you need its a $1-200 investment but worth every $$$ filter last 2-3 years....AERO SPACE TECH

They sell smaller systems too....it all depends on your grow areas size as to what size filter and fan you need

You will need a fan also.......my set up/ filtration system cost me $500
I grow skunk alot of it.......no smell leaves the grow area and what does exit out of the filter/fan/exhaust has no smell of weed
