As long as generating the faucet, water flow first passes through a filter non-woven screen. This screen acts as the first layer to block large sediments such as sand, debris, and dirt.

Then, the water will reach the second layer. This layer is a compressed block of activated carbon.

The carbon granule contains millions of pores on its surface, which can ultimately absorb chemicals in the water such as chlorine, typically.

One gram of activated carbon has a corresponding surface area of 32,000 square feet.

Thanks to a natural reaction called adsorption, the slower the water flow goes through the carbon area, the more responses and more pollutants can be terminated.
