What are water filters?

A water filter is an appliance with the help of which water is purified for human consumption and other applications.

Water filters using activated carbon have a maximum surface area that maintains the flow rate and provides clean water. There are three simple steps activated carbon technology uses to filter contaminants. Let’s understand the working of a water filter in simple steps. 


  1. The first step of the working of the water filter is physical absorption. In this process, the large internal surface area physically filters out the sediments and contaminants.
  2. As water passes through it the activated carbon begins to act like a magnet for compounds such as lead and VOCs.
  3. Then finally, the chemical reactions take place inside the filter and reduce chemicals and pharmaceuticals.
