Can i use a 6 inch duct booster on a carbon filter?

Yes you could try but it doesn't work lol. I've seen lots of DIY "how to recharge" but to truly recharge carbon it does need extreme heat.

Sometimes Budley, your full of shit! This is one of them!
The recharge I speak of is from Pfizer. You think they lie?
I saw the thing about 1200-1500 deg needed to "recharge" activated carbon.
The problem with that is that the FLASH POINT OF ACTIVATED CARBON IS 752 DEG F!
Your thing about "autoclaves" is BS too! They only can reach a bit over 320F . Pressure in them only makes the sterilization faster. Not the autoclave hotter!

Here ya go Doc and sorry autoclave may have been the wrong word, no need to get all attitudy Judy lol.
Reactivation of activated carbon - saturated activated carbon of the SC 40 standard is reprocessed in the rotary counterflow furnace with a gradual increase of temperature from 20 to 830 °C and a delay period of approximately 30 minutes, i.e. conditions similar to those in the production of activated carbon. The activation medium is water vapour and burnt gas. This technological operation gradually results in the drying, thermal desorption of volatile adsorbed substances, and the activation (renewal) of the inner surface to 92 - 100%, exceptionally to more than 100% (additional reaction of the amorphous carbon) of the original value. The operating temperature is sufficient for the pyrolysis of also non-volatile organic substances. Using the equipment, it is possible to reactivate the activated carbon e.g. by polymerising substances, siloxanes, chlorinated hydrocarbons, etc.
This procedure of reactivation has considerable quality advantages as compared to other technologies (e.g. a thermal desorption of 250 - 350 °C), when lower temperatures do not result in the restoration of the activated surface.
The processing operation results in the reactivated activated carbon of the quality standard SC 40. The secondary product, that is a vapour-gas phase containing desorbed substances and burnt gas, is disposed of in an eco-friendly manner by means of mechanical filtration, burning, and alkaline and acid washing. These changes can be identified as a general reduction of the weight of activated carbon by approximately 25% against the saturated activated carbon.
These changes can be identified as a reduction of the bulk density of activated carbon, approximately from 0.6 t/m3 to 0.5 t/m3 and the restoration of activated surface - determination of an iodine value or absorption isothermal line.

Yes we could google search all day doc lol. I actually was at a seminar last month on indoor air quality and the PHD that was talking had said that to fully recharge AC you need extreme heat so am I full of shit as you say, which really, you felt that was necessary? Way to cranky Doc lol. I don't think I'm full of shit but hey if you have tried it and it works then perfect I learned something and that makes me happy.

Give me a link to that please!
I gotta ask them a real interesting question.......If they are going over the flash point of the media being heated. How the hell are they not getting combustion? Something in that process. NEVER MIND! I see it now, water vapor.......Must be held at a particular level till under 400c and then stopped. That would be how the drying is achieved.
The highlighted part points to the fact that the information I give IS factual, and that the info you give is for some kind of rather hard to desorb volatile substance. It also points to the fact that what I listed to do at lower temps as effective for our use.
Read it again Budley! "This procedure of reactivation has considerable quality advantages as compared to other technologies" In other words, I'm listing the "other" technologies!
Your contention that I'm incorrect and the implication that what I suggest to do is not effective, is incorrect!
Phizer does not have the ability to run a system of that sort. They do what works for them. It increases the effective life of their AC by a factor of 6. It's called saving money.
Looks like we're both right!
My way works for what we do!
Yours is more effective in the long run, when the need to remove particular volatile substances, that we, for what we do. Don't have much problem with!
I'd give you half on that but, you missed the FACT that my way works too..... C-
