3 µm. This curve is produced by overlapping filtration mechanisms. Some mechanisms do the job only on particles bigger as opposed to size of your gaps throughout the filter while others only work on lesser particles.
3-micron particles, H13 can goal even more compact particles at a small 0.1-micron. This Superior degree of filtration is your best option for highly vulnerable patient populations. It is just a prime option for many who experience allergic reactions as the filtration is significantly simpler than a normal HEPA filter.
