It's not completely accurate. Just another show pushing propaganda. I'm so disappointed in a episode telling which mask was the best. Both doctors say the N95 is better than the KN95 bc the KN95 was made in China well I bought the N95 and it's made in China too. I was trusting those doctors and the 3 women doing the tests all togather but now that I see the truth for myself and realize they didnt do a comparison with the KN95. Can't trust anyone they all in it together.
