I've used N95/N100s for work for decades, so I'm familiar with the fit testing, quality and comfort of the industry standard masks. A good respirator should allow one to work 8 to 10 hours somewhat comfortably and these BD masks allow this. Just to test it out, I rode a bicycle 12 miles wearing it.
To test for air gaps at home, I dehydrated a dozen Jalapeño peppers and ground them into a fine flour using a bread flour grinder. The smallest particle size is ~5 µm. The Jalapeño powder inhalation test is a good home method to test for proper fit.
While this test won't determine if it prevents small aerosols (0.5 µm), it does tell you if the respirator fits properly, because the Jalapeño dust will make you sneeze profusely if the dust gets in from air gaps. No gaps when I put it on correctly.
