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


Both the Urban Air Mask & Lite Air Mask is tested and certified with KN95 and we are in the process of getting both FFP2 and N95 as well.


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.
