| contents | <p>Indoor air pollution is a critical public health issue in densely populated countries such as Bangladesh, where PM2.5 levels indoors can reach <strong>75–200 µg/m³</strong>, far exceeding the WHO safe limit of 5 µg/m³. Chronic exposure contributes to respiratory illnesses, allergies, skin conditions, and over <strong>102,000 premature deaths annually</strong>, including <strong>5,000 children under five</strong>.</p> <p>This research presents <strong>Project Nisshash</strong>, a clean-tech startup offering a <strong>modular dual-flow air purification system</strong> that actively exhausts polluted indoor air while supplying purified air. The system combines <strong>HEPA filtration</strong> for fine particulate matter, an <strong>activated carbon layer</strong> for smoke and chemical pollutants, and a <strong>dual-fan airflow architecture</strong> to prevent pollutant accumulation.</p> <p>Project Nisshash provides multiple product categories, including <strong>tabletop purifiers</strong>, <strong>room purifiers compatible with existing cooling systems</strong>, and <strong>kitchen purifiers</strong> that replace traditional exhausts while purifying incoming and outgoing air. The study evaluates the system’s <strong>feasibility, expected health impact, sustainability, and alignment with Sustainable Development Goals (SDG 3, 11, and 12)</strong>.</p> <p>The findings demonstrate that Project Nisshash can significantly <strong>reduce indoor PM2.5 and allergen levels</strong>, improve overall indoor air quality, and provide a scalable, affordable solution for households, educational institutions, and small commercial spaces.
