What standards do children's masks meet?

In terms of epidemic prevention performance control, the bacterial filtration effect has been increased to 98%, reaching the international leading standard; the particle filtration effect has reached more than 85%, which is much higher than that of disposable medical masks and medical surgical masks.

In terms of safety risk control, requirements are put forward on the folding resistance of nose clips, pH value, formaldehyde content, decomposable carcinogenic aromatic amine dyes, etc., so as to avoid affecting the physical and mental health of students.

In terms of technical requirements for comfort, indicators such as ventilation resistance, mask belt breaking strength, and folding ratio are specified.
