Mask are protective respiratory devices designed to achieve a very close facial fit that is typically round and designed to form a tight seal around the nose and mouth. It is critical to properly fit and wears for them to work effectively.

Challenges I ran into

Challanges like to build the filter of mask. It took time to research to build the respirator. At last we came to an iteration where we used 4 layer of cloth to use filter.
