Will carbon filter remove (capture) CO2?

Simple question, if CO2 enriched air is sent through a standard active charcoal type filter, will the air exiting the filter have less CO2?

If someone with a CO2 meter could make a quick test, I would be very grateful, otherwise does anyone have an opinion?

Thanks!

A carbon filter traps odour.

However if you are Co2 enriching the air whilst exhausting out of the grow through a carbon filter then you ARE loosing Co2 and wasting money.

In order for Co2 to be of the most benefit you need a sealed environment where a fan and filter is setup just within the room. To scrub the air within the grow and not exhaust it out of the grow.

This along with elevated temps and generally a stronger nute mix makes the most of Co2.

Thanks J for your response, I understand your point about being wasteful, in this case filtered air is not exhausted outside but instead cleaned air is recycled (think closed loop system).

The point of my question is to understand if the filter is capturing any CO2?

Is it scientifically possible that carbon in the gas form can bind to carbon in the solid form as it passes through a carbon filter? To my limited thinking CO2 put through a carbon filter might result in O2 coming out and some amount of carbon atoms sticking in the filter... Either clogging it up or helping it gain more carbon efficiency (blows my mind to think this one through).

From a practical stand point, I simply can't afford a metered CO2 controller right now, calculations and best guesses are my only tools. I want to factor in loss from filtering and also, to know if filters will clog faster with enrichment (clogged by CO2 directly, not into debating how much more smelly CO2 can make a plant which in turn wears the filters faster, etc.).

OK, so I know that carbon traps smell (traps the smelly particles floating in the air I guess), and I think I know that CO2 has no smell so I assume no smelly particles to clog up the filter. However in truth the only thing I know for sure is that I don't know jack about such scientific things so I figured the very best way to know 100% for sure is to ask if anyone could run a quick test and meter the air for CO2 before and after the filter to confirm.

Short of empirical data, does anyone with scientific knowledge of this topic have an opinion?

Thanks kindly!

I have done it in room 1500 ppm to 690 in 7 min so take what you will. I had scrubber>duct>light>duct>fan for 1st day all out tent fast

I answer is no but I can't prove it. How ever most people will say that you need to replace your carbon in the filter every 2/3 grows or at least bake it to refresh.

The reason weed smells up the place is described well in the grow Bible but I don't have my copy on hand and I don't remember the technical term.

I just built a co2 generator using sugar, yeast, and water in a 2-3 tent with carbon filter. I have a co2 meter on the way. I will know then.

You had a leak somewhere. Been working with co2 since before it was cool. I work with 20lb bottles with regulator and a co2 sniffer. Each bottle lasts over a month during flower.

Scrubbers do not filter co2. Co2 molecules are too small for the pores in active carbon to trap them.
