Looking for recommendations 6" or 8" carbon filter

I have two 6 " inline carbon filters that I've had since 2018. i seem to be getting loud odor from 4x4 tent after putting into 12/12, so I hooked the filters one on each side of the fan. I had used one filter sparingly when first purchased and the other very little if at all. They seem to be doing nothing at all. I have washed the prefilters also. I've read that you can wash the filters by dunking in very hot soapy water and then in hot clean water then letting them dry, I will be trying that. I was wondering can you disassemble the canister by taking one end off empty out the old charcoal and replace with fresh activated charcoal? What methods have worked for you?

Yes, you can open them up and replace the charcoal, depending on the brand/construction it can be easy or difficult. There are instructions on several internet sites. I don't think just washing the filter will do a lot of good, it might work short term. Much better off to either open it up and wash the material , then dry it in the oven (to re-activate it) or simply replace it with new activated charcoal.

Any idea where I can find the DIY videos? I'll keep looking. Do you think it is worth it?

I like my large can-Filters, mainly because I can open them up and clean and re-activate the 16lbs of carbon in there, reseal it up and use it for another year. I own 2 of them and have been using them for about 10 years.

Any luck replacing the socks inside? Mine was torn in numerous places making it a real pain to replace afterwards :rolleyes:

if you have a cannister type with screws holding the top and cages it's pretty self explanatory. i've recharged a few.
 
If you have a pot large enough for the size filter you have you can recharge it easily by boiling the entire filter in water and vinegar for a couple hours then let it sit for a few days to dry the charcoal.

Had a buddy that did this service for commercial ops. He told me at first he would remove the charcoal from the canister body but, depending on the manufacturer, it would not always go back in very easily. It was much easier and just as effective to boil out the entire unit and not have to disturb the charcoal inside.

These were for Can Max type filters that were all metal. If your filter has any plastic parts it may not survive the boiling process.

That sounds fantastic but what happens to the mesh nylon “bag” inside of it that keeps the charcoal from falling through the holes of the filter? It doesn’t melt in the boiling water?
