@MyrneStol @akm5376 @sameo416 @KawasakiKR11 @_stah @Joseph_Browning @armand_kj In other words, not very much. Air is supposedly 50/50 fresh/HEPA which even double 3.2 l/s would not be very much. Wear a good mask, and if you recognize that this isn't a robust solution (e.g. imperfect fit, food/water, inconsistent vent, etc.), minimize flying.

@MyrneStol @akm5376 @sameo416 @KawasakiKR11 @_stah @Joseph_Browning @armand_kj 换句话说，不是很多。空气据说是 50/50 新鲜/HEPA，即使是两倍 3.2 l/s 也不会太多。戴上好口罩，如果您认识到这不是一个可靠的解决方案（例如不合适的配合、食物/水、不一致的通风口等），请尽量减少飞行。
