Air Filter pipe | Covid-19

This is a little air filter that I came up with I don't know how effective this would be but depending on what you put in it to filter its better then nothing. Look fancy as you fight for that TP. I made a smoothed version I couldn't decide what I liked better so I uploaded both. there is a 3mm hole in the hinge so a I used a filament piece for the time being but it should work with a 3mm diameter screw.
