I don't need to test it. Empirical evidence showsI that a filter media can block things. Think of air filters oil filters even the screen on a storm window. You can test it as well. Get some water sensitive paper for testing sprayer nozzles. Sniff some ground pepper. Sneeze on a sheet of the test paper. Next time put a mask on just before you sneeze on the test paper. | |
