Filtration Process

Mechanical - A physical barrier traps particles to remove them from water.

Adsorption - Traps particles and some dissolved contaminants through physical and chemical interactions.

Ultrafiltration - Removes ultrafine particles and bacteria.

Multi-stage - Multiple filter stages that target specific contaminants.

Reverse Osmosis - Removes all contaminants to produce pure water.

Alkaline - Increases alkalinity (pH) and antioxidant level.

Mechanical
Type of Filter

Activated Carbon Block - Removes chlorine, organic compounds, and other contaminants from water.

Catalytic Carbon - Removes chloramines and some heavy metals; more effective chlorine and organic compound removal than activated carbon block filters.

Anti Scale - Prevents hard water scale and corrosion.

Sediment - Removes suspended particles such as sand, dirt, rust, and sediment from water.

Pleated - Removes bacteria, viruses, ultrafine particles, and other contaminants from water.

Granular Activated Carbon - Removes chlorine and some other contaminants; less effective particulate filtration compared to carbon block filters.
