These filters often utilize triggered carbon; activated carbon is a form of carbon processed to have small, low-volume pores that increase the surface area offered for adsorption of pollutants or chain reactions with the contaminants triggering them to comply with the carbon. At Epic Water Filters we utilize solid triggered carbon blocks for our filters which our company believe is the exceptional method to filter impurities out of your water.

Granular activated carbon filters (GAC) have loose granules of carbon that look like black grains of sand. These black grains of carbon, are discarded into a container and the water is required to take a trip through the container to reach the other side, passing by all of the grains of carbon.

These filters force the water to try to find a method through the solid wall and countless layers of carbon until they reach a channel which leads the water out of the filter. Both filters are made from carbon that's ground into little particulate sizes. Strong triggered carbon blocks are ground even further into a fine mesh 7 to 19 times smaller than the (GAC).

Flow channels also establish in between the granules of carbon themselves, leading to less reliable filtering as there is less and less contact time in between the water and the carbon.  https://olympiancares.com/questions-and-answers-about-water-quality  triggered carbon blocks, on the other hand, are much tighter and will not even let microbial cysts like giardia and cryptosporidium (7 to 10 Microns in size) go through the filter without getting captured in the millions of layers of carbon.

During this contact time is when hazardous impurities like lead, comply with the carbon and are gotten rid of from water. This happens during a procedure called adsorption, the other purification technique that strong activated carbon obstructs use is called depth filtration. This is where the thickness of the carbon block filter enters into play to assist remove contaminants as they have to travel through these thick carbon walls.

This is why when you are using a Brita water pitcher filter (GAC), the filter will keep going and going long after it has stopped getting rid of any water contaminants. A good 5 micron sediment filter in front of your carbon block filter is an excellent way to extend the life of the strong triggered carbon blocks and make it more efficient.
