how long do carbon filters last?

If that's the case I may as well get smaller packaging from an aquarium store.

That's different stuff made for filtering water and won't work worth a damn for filtering air. I'd hunt online for a smaller package of virgin Australian charcoal if you can get it or find the right temp and time to bake yours and get it working again. If the whole thing can fit in the oven you could try that. Will stink out the house tho. Burning toast covers many smells. :)

I wonder how long a brand new, never unboxed carbon filter would keep? Forever do you think?
I've one that's been lying in my garage for 10+ years.
Maybe I'll just need to roll it about on the floor a bit to loosen the compacted carbon in it?
What y'all think?

Is yours all sealed up in plastic wrap still? I never touched mine other than to take it out to have a look. Sealed up airtight in pretty heavy plastic so should be good forever. I don't think rolling it on the floor will do much. Those things are packed with a vibrator at the factory to be in there really tight. Dumping it out and baking it to reuse breaks it down a bit so it doesn't quite fill it all up so laying a ring of foam rubber or something before riveting/screwing the cap back on will keep it snug.

With the addition I am adding to the grow room I could use an inline carbon filter better. Separate fans feeding into a Y junction with back-flow flappers so both feed 6" hoses into an 8" filter but I'll figure something else out. I may just blow the air from the addition into the main grow room and have the new 8" fan take care of things. Hoping to set up a sealed grow room with CO2 but need a bunch more money for that.

We have the 20 yr old making coconut oil infusion all the time. Stink is not an issue here. I'll stick it in the oven at 220c for ? long would you recommend?

I don't know what they put in cheaper ones that makes them work so poorly. I think it may be the quality of the actual carbon. To buy a 25kg bag of quality carbon is over $300 from a air purification specially industry. If someone can answer this it would be greatly appreciated.

They use pelletized coal in the cheap ones, not activated bamboo charcoal.
They put it in a porous bag and drop it in the filter, not even vacuum packed.

I'm not sure of the temp or duration to cook them at to drive out the old stank. I get almost no smell when making my cocobudder and do it on a hotplate beside my desk in the mancave so I can stir it often without having to get off my ass. :) I decarb right in the oil so that doesn't stink up the house either.

House reeks of garlic these days since the wife started packaging up her garlic for shipping out. Over 1500 bulbs and going for double next year. Good thing I like garlic.
