it is not designed only for coronavirus, but also for those who do jobs

that need a protection mask against dust or other .. for example (carpenter, painter ... etc.)

therefore the filter to be mounted depends on the desired protection.

THIS MASK IS;_ washable and sanitizable with interchangeable filter.IS_ it is quite versatile, just enlarge the stl model for your face type.

**** The author does not claim that this mask is a virus known as panacea,but I think it is better than the paper ones and its protection depends a lot on the filter you use.

You can contact me for any information

thanks
