The World Health Organization (WHO) states that 92% of people worldwide do not breathe safe air. Cities are more polluted than ever before; people are exposed to Particulate Matter (PM) from various sources. Although masks have long been used to protect human respiratory system from pollutants, they face a major problem of inward leakage due to air gaps. This project aims to enhance the ergonomics of the mask by designing a new geometry while remaining at low filter cost. The design targets urban population who are constantly exposed to polluted air. Mask geometry is redesigned in order to accommodate various facial sizes and thus reduce air leakage. While keeping the new mask design cost-effective, new filtration techniques are considered to enhance airflow through the filter
