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.

I've got a baby red eared slider and I don't have a clue how often I need to replace the active carbon in the water filter.

Does anyone have a rough idea of how often it needs replacing or how to tell that it needs replacing?

ive read every two weeks but i think its a bunch of bull**** just another way for companies to make money. ive always changed mine every couple months or when ever the water starts getting cloudy and isnt staying clear for very long even after you have cleaned the filters out real good

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."

Carbon filters work by absorption.
Once the filter is full, it's dead and should be replaced.
