What’s the difference between KN95 and KN90 mask?

1. Different grades. Mask KN90 has a lower non-oily particulate protection level than KN95.
2. Different filtration efficiency. The mask KN90 can filter more than 90% of particulate matter; The KN95 mask can filter more than 95 percent of particulate matter.
3. Different air permeability. The more efficient a mask is, the less breathable it is. Therefore, the KN90 has better air permeability than the KN95.
4. KN90 and KN95 which can be antivirus? It’s all preventable. In the case of face mask shortage, the KN90 rating can fully meet the requirements of our non-medical staff. KN90 and KN95 are only mask filtering grades, not mask models. The two are just different filtering levels, but for the general public, the KN90 is also available. At the same time, the higher the filtration efficiency, the worse the air permeability. Usually, the KN95 series of masks are for industrial use. Due to the high protection level, the air permeability of the mask is not good, and it will easily cause discomfort if worn for a long time.
