Covid-19 Mask with changeable filter unit
thingiverse
Respirator Mask Featuring Changeable Filter Unit and Enhanced Airflow I integrate a high-quality vacuum cleaner bag made of 3-layer synthetic material, treated with Carbon nano spray every time I use it. The plain filter canvas measures 77×177 mm in size. Additional filter layers can be easily added for improved performance. It's crucial to apply a protective varnish coating using a spray paint to ensure the surface remains durable and long-lasting. To facilitate easy disinfection, I recommend using PET or ABS materials for the mask and filters units, ensuring they won't melt during the process. Future Development: Implementing an additional airflow enhancement wave to further improve the overall efficiency of the respirator.
