@JeffCavanagh1 @AvrilaWrites @ryderseashells @wecarryon2 It depends on the cloth (also fit, but that applies to all). Some cloths can function as a good filter.
But there is no way to break this down in the field, especially without any sort of product certification.

@JeffCavanagh1@AvrilaWrites@ryderseashells@wecarryon2这取决于布料（也适合，但这适用于所有人）。有些布可以起到很好的过滤作用。
但在这个领域，尤其是在没有任何产品认证的情况下，无法打破这种局面。
