Activated carbon filter purification comparative analysis

With various types of water filter become more and more popular, more and more people began to wonder if the water filter exactly is what to do, how they work, such as 'activated carbon' and 'charcoal' word in most filters is quite obvious, whether it is a whole house filter, under the sink filter, filter, mesa and even filter bottle, will appear an understandable question: 'what is activated carbon, charcoal is what? And activated carbon filter is common in the present moment. Charcoal is carbon, we can simply say, activated charcoal is treated with oxygen carbon, when doing so, the carbon atoms in charcoal can open the millions of small openings, so they are 'active', the reason to do so, because when the pore of carbon atoms in open, they will become highly absorbent, they have a smell from the gas or liquid absorption or coloured substances, as well as a number of other chemicals and pose a threat to our health. If the use of special manufacturing technology, the surface area of porous carbon can be achieved 300 - per gram 2000 square meters, a few people use 'activated carbon', while others use 'charcoal' when was the cause of activated carbon is activated, it will become a charcoal, so, for water filter, activated carbon and charcoal is the same thing.
