Jun 12, 2020·The masks are actually best for particles either larger or smaller than that 0.3 micron threshold. “N95 have the worst filtration efficiency for particles around 0.3,” Marr said.
Particle (Contaminant) Size Chart in Microns- n90 Maskenfilter Mikron ,1 Micron = 1000 NanoMeters. Note the size range of viruses in this chart… .005 – 0.3. The .005 is much smaller than many water filters claim to remove! What is important to remember is the size of viruses that have proven to be harmful or deadly to humans.Mask Ratings - N95 vs FFP2 vs KF94 vs KN95Aug 23, 2020·The only difference comes in with N100 and P100 rated masks. Complete filtration is at this point impossible, and a 100 rated mask is effective at stopping 99.97% of 0.3-micron particles.³. …
Mar 29, 2020·As hospitals around the country desperately seek N95 respirator masks to protect health care workers treating COVID-19 patients, the federal government has blocked imports of what might be the world’s most abundant alternative.. That mask is designed to filter out at least 95% of particles that are 0.3 microns or larger in size — the same measure used for the scarce N95 mask.
Surgical mask standards have higher requirements for capturing virus-sized (0.1 micron) particles, however they vary by region. Pollution masks (respirators) typically capture >90% of virus-sized particles. You can use the rating system in the table above to see …
Several 3M masks were able to capture over 99% of tiny 0.01 micron particles (10 times smaller than the coronavirus), even while on people’s face. What’s more, surgical masks were surprisingly effective, capturing 63% of the tiny virus-sized particles. Read more: Scientists randomized nurses to wear masks and tracked who get infected.

Complete filtration is at this point impossible, and a 100 rated mask is effective at stopping 99.97% of 0.3-micron particles.³. In other words, the higher the number the better the filtration efficiency. To be put even more simply, the higher the number, the better.
