There are a couple of certification standards that are more well known globally and recommended by governments and authorities around the world during Covid-19:
N95 - US Standard
FFP2 - European Standard
KN95 - Chinese Standard
Air Mask Active, Urban Air Mask 2.0, Air Mask Lite & Lite Air Mask all comes with our Opti filter included in the purchase. These filters are tested and certified with KN95, the filters that are included with Air Mask Lite has both KN95 and FFP2 Certification.
There are very few differences between the different standards and most of them are so minor that the user won't be able to recognize a difference. In the table below you'll find a comparison between FFP2, KN95, N95.
