I wash mine in warm soapy water, then I bake it in the oven 225 degrees,for twenty minutes, till dry and heated well, the soap takes any oil off the oven recharges it, done it several times, works great, if in ahurry and your metal filter housing will fit in the oven you don't have to take it apart

I was thinking about putting the whole filter in the oven too
maybe cleaning the filter in the bath tub with dish soap water. Spin the shit out of it over and over to rinse real good.=======================================
Any other insight? Or did he hit the nail on the head?

I'm not sold on weather ir works or not. Security is an issue,here's a thought http://www.amazon.com/Filter-Coconut-Granular-Activated-Charcoal/dp/B00GKVNI8E or http://www.ebay.com/itm/5-Lbs-BULK-Activated-Carbon-Charcoal-Granular-GAC-AIR-Filter-Odor-Hydroponic-/331660545846?hash=item4d38824f36:g:2HQAAOSwFnFV80oj

Do you mean charcoal for a carbon filter?
None of these methods ^^^^^ work.
You need a kiln. You have to bake it at 1800 degrees for a couple hours.
You can buy replacement charcoal for about $150. It would be cheaper to buy a new filter. Presh filter and green gator filters are the best.

As stated, in order to "re-activate" charcoal, it needs to be heated to high temps that can not be done in normal ovens. Washing and bake drying may help a little, but it will not burn everything out of the charcoal and "re-activate" it.

It seems it can be recharged. Talk to this guy.

Personally I found the thread very helpful. I didn't know you could reactivate them at all. I have bought 4 whole new filters over the years at pretty rediclous costs I might add.

Use a biodegradable, unscented soap - NOT a dish soap..Rinse with RO! Labs use de-ionized water, but RO will work!.....Long dry times are more effective in the oven and a convection oven that moves air inside is really the best.....Rising temps to 500F can shorten times.....go about 2hrs at that temp - about 5 with 250F.
Remove the Carbon to wash and dry and use sheet pans with 1 layer of carbon on it - do not pile it for oven drying.
Many carbons are actually a "charcoal" of some sort......High temp methods can start them "burning"...not good!
That is how the maint. people for chem labs in drug companies do it......

You can re-pyrolize at 800-1000F. Otherwise it's not like new.
Temperatures below that, even 500 in the oven, won't remove everything. So maybe your carbon is back to 50%? 70%? Who knows
The links above show a weed burner / flame thrower from a store, and that'll get temps where you need them
The risk is burning the charcoal, so some ash might be created. No harm, just don't use it in the filter

if you know anyone who powder coats or paints cars or blows glass, see if you can stick in their kiln
