Carbon Filter Cartridges

Carbon Filter Cartridges are primarily used to remove taste and odor from chlorine present in all water from a public water system. Some carbon cartridges reduce or remove lead that can be present in water.

Micron Rating Pollutant Removed
0.4 Micron Chlorine, Taste, and Odours
0.5 Micron Chlorine, Taste, Odours, and some cartridges Heavy Metals, Cysts, Hardness, Chloramines, TDS
1 Micron Chlorine, Taste, Odours, and some cartridges Heavy Metals, Cysts, Hardness, Chloramines, TDS
5 Micron Chlorine, Taste, Odours, and some cartridges, TDS, hardness
10 Micron Chlorine, Taste and Odours

This chart represents the pollutants being removed according to the micron rating in our selection of filters. The micron rating indicates the pore size of the cartridge. However, the filtration media within the filter indicates the pollutants being removed. 

Carbon Filter Cartridges

Activated carbon block is a blend of fine activated carbon, water, and a suitable binder that is mixed and molded and hardened to a filter cartridge of any size and shape. Sometimes activated carbon is combined with specialized media to provide customized performances for specific contaminants. For example, Nano-Silver Carbon Filters are well known, and use not only the properties of the carbon, but Impregnated Silver, which gives the filter bacteriostatic properties, and prevents the growth of bacteria within the filter.

Also, the binder used to hold the carbon and create a solid matrix for the carbon block, gives faster adsorption kinetics and generally two to four times greater adsorption capacity than equivalent volumes of loose granular activated carbon.

Carbon Filters Filtration Capability

Activated carbon block filters typically have a 0.5 to 10 micron filtration capability, making it also helpful for particulate filtration, removing taste and odor from chlorine, insoluble lead reduction, and demonstrating, in some cases, removal of Giardia and Cryptosporidium.
Carbon is a very versatile and highly effective water treatment medium. It has immense surface area. Approximately half a kilogram of carbon contains a surface area of over 50 hectares (0.5 square kilometers). It is the best known treatment for organic chemicals, volatile organic chemicals, pesticides, herbicides, chlorine and its by-products. It is also an unchallenged taste-and-odor improver. When arranged in solid carbon or extruded carbon block format, it also provides very high quality particulate filtration, in some cases down into the submicron level.

Filter cartridge manufacturers rate cartridges in “microns”. Microns are a size measurement of the pore size, so the smaller the number, the tighter the filter. One-micron filters are for drinking water only. In general, they are too tight to filter large amounts of water without slowing the flow to unacceptable levels.Filter cartridge manufacturers also use the words “absolute” and “nominal” to describe their products’ micron ratings. Absolute means absolute. Nominal means “more or less.”Carbon block cartridges are available in a variety of sizes and flow rates, and effectively provide good general-purpose drinking water filtration.


Most carbon water filters are efficient removing: chlorine, particles such as sediment, volatile organic compounds (VOCs), taste and odor. However, there are other harmful pollutants that are encountered in the water. For instance, Iron, Molybdenum, Lead, Vanadium, Nickel, Zinc, Cadmium, Copper, and Chromium are the most common heavy metals found in drinking water, and the best way to reduce significantly their levels in drinking water is through a reverse osmosis system. It is also known that distillation and ion exchange methods are effective. However, there are only two world wide known carbon cartridges, which remove these harmful contaminants. Firstly, GEYSER Aragon Water Filters are highly efficient removing not only Chlorine and Chloramines like all carbon filters do, but removing Particles >2 microns, Lead, zinc, cadmium, cesium, Chlorine, Chloramines, Pesticides, Iron, Aluminium, Turbidity, Oil Products, and radio active elements. Secondly, Omnipure Carbon Filters with LEAD removal properties, remove heavy metals as well, but their filtration capacity is not as high as the one in Aragon Filters.
