@jklmd123 @FinchTH Some of them e.g. Aura are definitely better than very often poorly fitting KN95s that are also often fake.
KF94s seem better at fitting random people reasonably well. Similar in design to Aura may be part of it.
@jklmd123 @FinchTH 其中一些，例如Aura 绝对比通常很不合身的 KN95 更好，这些 KN95 也经常是假的。
KF94 似乎更适合随机人群。与 Aura 类似的设计可能是其中的一部分。
