The filter treats water using an adsorption process. Meaning absorbs contaminants in water and sticks in the filter.

After filtering water for some time the filter gets fully occupied with contaminants demanding you replace the filter. Mostly activated carbon water filter lasts for 6 months but this depends on water quality and usage.
