@RidleyDM @Rose_Marie_Holt If you're ever in a situation of needing one, try the VFlex N95. They're so breathable, I honestly can't detect any breathing difference, little issue of temperature, doesn't block voices (does block lip visibility of course), many smells penetrate (they're not particles).
@RidleyDM@Rose\u Marie\u Holt如果您需要，请尝试VFlex N95。它们非常透气，老实说，我检测不到任何呼吸差异，温度的小问题，不会阻挡声音（当然会阻挡嘴唇的可见度），许多气味穿透（它们不是微粒）。
