not to get off subject.... and i do like these filters... they seem nice... i would maybe customize the idea a bit.... maybe a couple of layers of those filters with the carbon dust in between.... thats pretty much what i did on my setup.... all of the vents have those filters cut to the duct size and stuck inside with foil tape... but i have to say that i would recommend the following much more... its a liquid caled ONA. and you can make these little buckets with a fan on the top that disperse the smell really good I have it attached in the inside acting as a second exhaust... it works great.....




you can see on the other exhaust i put coming from the flowering chamber has those carbon filters in the inside ....

I have tried the ONA bucket SO many ways, and none lasted more than a couple (literally 2 or 3) days. If I ever try it again, I will use straight ONA, no cut with water (9 cups water to 1 cup ONA...HA!...BS).

What was the bucket size you used? I have used the ONA STORM with a 7 gallon bucket---it lasts 8 to 10 weeks for me( I run it 24/7 all through flowering) I have a canfan 12" with matching scrubber as well on 24/7. the final exhaust is through a canfan 6"HO and matching carbon filter. I also run two ion generator from hydrofarm. I know this is overkill but I sleep great at night and my pad always smells like fresh laundry.

i feel ya. the bucket is 5 gal. listed in thumbnail photo above. i had tried extra strength febreeze before the ONA. nothing worked long. i'm trippin' because i really want a more advanced and heavy duty scrubber, but i cant justify it because my cheapo is pulling its weight. (now what the hell was the kermit joke? )

you could wrap the entire screen cylinder with a panty hose, fill it with fish tank carbon...and lose the prefilter for more airflow, all in all this is a good design...good shit

super awesome diy filter, thx for the infoyou could throw put a screen on the end of the filter that meets the duct and fill the hollow filter with vapor phase activated carbon(better than fish tank carbon, which is liquid phase) for super boosted filtration. 7 pounds would probably fill the one you made. like jordan said, you could probably even lose the pre filter w/ carbon

yeah. i ended up putting the prefilter inside with pantyhose on the outside. works great for grapefruit haze. purple kush forced me to fill the inside with activated carbon. i wish i knew where to find that vapor phase activated carbon.
