Non Woven Triple Layer Disposable Medical Masks Barriers To Dust Particles

Triple Layer Disposable Medical Masks Barriers To Dust Particles

Introduction

Ordinary medical masks are used to block the splashes exhaled from the mouth and nose, and can be used for disposable hygiene care in ordinary medical environments, with the lowest protection level. It is suitable for general health care activities, such as sanitation, liquid dispensing, cleaning bed units, etc., or the blocking or protection of particles other than pathogenic microorganisms such as pollen.

Compliant with the relevant registered product standards (YZB), generally lack of filtration efficiency requirements for particles and bacteria, or the filtration efficiency requirements for particles and bacteria are lower than medical surgical masks and medical protective masks, only 20.0% for aerosols with a diameter of 0.3μm -25.0% protective effect, cannot achieve the filtration efficiency of particles and bacteria, cannot effectively prevent pathogens from invading through the respiratory tract, cannot be used for clinical invasive operations, and cannot protect particles and bacteria and viruses, only for dust particles Or aerosol plays a certain mechanical barrier.
