You might consider a bigger Can air scrubber or another one - I've seen some as big as me for a similar size grow op. I saw yours in the corner of one pic. It'll last you longer and give you a better sense of security, knowin the smell is contained.
That lil blue filter is great for filtering out microbes like fungal spores, if you can make it the only inflow of air to the grow room. Try to seal off every lil crack if possible so that you reduce the chance of introducing a pathogen; and shower everytime before you go to work there and wash your hands (or wear gloves). Clean is keen for makin green!
Yeah, sounds like me being a germ-phobe, but when you have thousands of dollars in gear and bomb genetics and nutes, the last thing you need is for some bug to fuck your grow op. Prevention is key. You really do not want to be combating fungus or insects, cuz once they are there its too late, they found their new home.
