How Does Uv Lamp In Water Filter Work?

Overview Of The Uv Lamp In Water Filter Mechanism

A uv lamp in a water filter is used to eliminate harmful microorganisms and bacteria from water. This is achieved by exposing water to uv-c light, which speeds up the process of sterilization and provides clean drinking water.
