xiaomi purely air pollution mask replacement parts

thingiverse

Since COVID-19, the new world order has mandated mask-wearing throughout the year, which isn't a problem for me since my city consistently ranks among the top-10 most polluted places on earth. Wearing a mask is highly recommended from 3 to 6 months of every year due to our notoriously poor air quality. However, I've noticed that constantly reassembling and replacing the filter while cleaning the outer fabric layer takes its toll on the plastic components. I have a standard air pollution Xiaomi/Purely mask found online. The parts that suffer from excessive wear and tear are the top and bottom plastic rings that come together to compress the filter with fabric, and also enable you to twist into place the small fan adapter. Since there isn't a 3D model available for these components, I've decided to draw them myself. Feel free to use this design and stay safe!
