What is a charcoal filter?

A charcoal filter is an excellent way to remove chlorine, lead and pesticides from your water.

A charcoal water filter works by adsorption, in which pollutants in your water that need to be treated are trapped inside the pore structure of the carbon cartridge.

What does charcoal do in water filtration?

With charcoal filters, these contaminants are trapped by the large surface area of the highly porous carbon granules inside a charcoal cartridge.

The adsorption process occurs when contaminants become stuck onto its pore structures.

What is Activated Charcoal?

Charcoal is a black powdery substance derived from burning a source of carbon such as wood or coconut shells.

High-temperature activation changes its chemical structure to create ultrafine particles with more surface area which binds and helps remove many heavy metals, chemicals as well as intestinal gases.

The Difference between Carbon Block and Granular Carbon Filters


There are two types of carbon filters: Carbon block and Granular Carbon. 

Both filters are made from carbon ground into small particles.

Granular activated carbon filters have loose granules of carbon similar to grains of sand. 

Solid block carbon filters have blocks of compressed activated carbon that are formed with the combination of heat and pressure.  Solid blocks are ground to a much finer mesh up to 19 times smaller than granular activated carbon filters.

Why Is Charcoal Good For Filtering Water?

In the 19th century, scientists discovered that activated charcoal can be used as a poison antidote.

In 1825 French chemist Charles Pierre Sublaine demonstrated this when he ingested arsenic and strychnine then chased it with an amount of his own making—and not only did he survive but was said to feel better than ever!

One gram of activated carbon has a surface area in excess of 3,000 m2 (32,000 sq ft).

One teaspoonful of activated charcoal has about the same total surface area as a football field!
