    • Abstract: Our water filter serves a dual purpose: it aids the environment and supports human health. In regions like Bangladesh, where many suffer from illnesses due to contaminated water, our research revealed alarming statistics of daily fatalities caused by waterborne diseases, not limited to Bangladesh alone. To address this global issue, we developed our water filter. Contaminants such as chlorine, lead, and bacteria are prevalent in dirty water, posing severe health risks. Failure to address this crisis could lead to further deterioration of our planet, potentially resulting in dire consequences, including loss of life. Our eco-friendly water filter, crafted from cardboard, underscores our commitment to sustainability. Utilising materials like quartz sand, crushed granite, charcoal, pebbles, and active carbon, our filter effectively purifies contaminated water, offering a lifeline to communities in need.
