Covid filter for trumpet
thingiverse
A simple COVID filter for trumpet made from a kitchen extractor hood filter that utilizes carbon filtration. I'm experimenting with this setup and unsure about its effectiveness. The filter easily attaches to the horn via three plastic tabs without requiring any modifications to the trumpet itself. This design is specifically tailored for 121mm trumpet horns, but it can be resized to accommodate other instruments. If you find this design helpful, a small contribution would be greatly appreciated!
