I own a Katadyn Combi water filter. Carbon refill packets for it are expensive. There are many places to buy activated carbon in bulk relatively cheap. Physically it's a trivial matter to buy in bulk and use it in the filter but I'm wondering about the quality of the carbon, the form of the carbon and how suited it is for the filter or anything else I need to be aware of when buying carbon in bulk.
I think you might be in for more trouble than its worth. Activated carbon will come in a powder form, most likely. So then you'd have to open the filters, dump out the old stuff, and hope your system has enough pressure to push through that much carbon.
I would look into some heavy research on the fabrication of carbon filters before I tried to do something like that.
Its sort of like saying "gas is expensive, i think i'll just buy oil on the open market, and refine it at home to make the gasoline."

Yes and no
activated carbon removes chlorine and chloramines (chemicals your water utility puts in water to slow bacteria growth) and activated carbon removes SOME organics. Some of the oils may be removed, but they may quickly saturate the activated carbon bed and pass through. Benzene and toluene are typical organics that are removed to some degree by AC beds.
As to bacteria, in fact activated carbon provides an excellent medium for bacteria to grow. AC is porous and since it is collecting organics, it provides water, food, and darkness. perfect for bacteria. And since you're removing agents that control bacterial growth in the first place, you should expect MUCH higher bacteria counts after an AC bed.
From my decade working with AC beds.

I spend $35 to replace the carbon filter on my water filter/pitcher every few months. Would the activated carbon used by home distillers be as good an option to filter my water? The exact brand I'm thinking about is Prestige stone activated carbon (.4-1.4mm), and I would be running it through a coffee filter in the existing housing on my water pitcher.
Can any chemists - amateur or professional - tell me if this would be a good or bad idea?
Not sure but if you want more information on filters look up the website for a company callled CUNO.

can anybody tell me why we put a pouch of activated carbon in a water filter ?
what are its advantages? any disadvantage ? when we have to remove its pouch . any defined time for its expiration ?
It isn't needed really. Your tank only needs a filter media. Most advanced aquarists only use carbon to remove meds after treatment of a tank and not much more. I really has no benefit for absorbing ammonia or nitrites. Your dechlor water conditioner De chlor will remove all the heavy metals (neutrilize them)
f
Other than neurtalizing meds there are no real advantages to carbon or not.
Carbon depending on what is in the tank is pretty much useless after only a few days in the tank before it starts to leach out what it has absorbed.
Salt water tanks do not use carbon at all. Even without a skimmer

Activated Carbon in HEPA Air Purifiers
Unless you’re an aquarium hobbyist or own a water purification system that uses carbon, the idea of activated carbon in HEPA air purifiers probably seems strange to you. Even if the concept isn’t completely foreign, most still don’t know exactly what activated carbon actually does.
How Is Active Carbon Used In HEPA Air Purifiers?
The first time most people encounter activated carbon is in choosing HEPA air purifiers. When most customers begin searching for air purifiers, generally due to allergies or asthma, they really have no idea how they work. As they are further educated about HEPA air purifiers, however, they will learn that odors and chemicals are the cause of the vast majority of their respiratory problems. Most quality HEPA air purifiers are designed to take care of not only allergens, but also the odors and chemicals in the air as well.
...BU research offers hope for Vrushabhavathi
&Ldquo;After the black coloured water was made to pass through the carbon column, we could extract colourless, odourless water within five minutes,” explains Sucharitha. Sucharitha, who is researching on activated carbon under the guidance of Dr Nandini, adds that apart from removing odour and colour, that activated carbon also extracts heavy metal like Copper, Chromium and Zinc. Elaborating further, she says 20 kg of activated carbon is sufficient for treating one thousand litres of water. And to prepare 20 kg of activated carbon, about 40 kg of agro waste is needed. The metals that are extracted by the carbon column can be used by electroplating industries and the carbon can be decomposed and used as manure, Sucharitha explains. Activated carbon prepared using bagasse has lignite content and 60 per cent more carbon. It is more effective than activated carbon obtained from other products like coconut shell, rice husk, almond seeds and maize cob. It is also found to be better equipped to remove metal content. A proposal has been submitted to construct a treatment plant in the varsity to treat Vrushabhavathi water.
