@tomofthenorth_ @Theresa_Chapple @sciliz @jaketapper There are options.
Flo mask, if it fits (no CI). Double masking a quality surgical (they come in kids sizes) with a tight fitting cloth mask over it also likely to be effective. KF94s also come in kids' sizes, though not sure about 4.

@tomofthenorth_ @Theresa_Chapple @sciliz @jaketapper 有选择。
Flo 面罩，如果合适（无 CI）。用紧身布面罩对优质外科手术（它们有儿童尺寸）进行双重遮盖也可能有效。 KF94 也有儿童尺寸，但不确定是 4。
