Problem with getting smell in control

[Rastakari2]

Hi. I have 4 autoflowers currently late in flowering.

I have my grow tent, light and 4 inch fan from this setup: Mars Hydro TS 1000 LED Grow Light+70x70x160cm Indoor Tent Full Kits With Speed Controller(Will ship out on 15th March)

I had a 100 millimeters wide bull filter with 200m3/h, but the air was coming out smelling a lot.

today I just got new bull filter and 100/125mm fitting piece for it. This bull filter now is with 125 millimeters and 400m3/h. It helped a bit but it still smells a lot.
I put also the old 100mm bull filter to the end of the tube where air comes from but still smelling a ton.
Only thing I have in my mind anymore that I could change is to buy bigger bull filter for the end of the tube as well. But I doubt that will make the change still that I need.

How do you guys that need to control smell during growing get it to go away? What kind of setup and filter(s) achieve you that?

Any help is much appreciated!​

Not sure what a bull filter is but a carbon filter attached to my exhaust fan kills all smell from the tent. I use AC Infinity 6 in but anything with activated carbon will absorb the smell. Good luck

+1 on the carbon filter. I even make a filtration system for my smoke spot in the basement with one. I blew into it and had someone smell the cloud as it came out of the filter and no smell.
