N95 Respirator during COVID-19 Pandemic

Main Article Content

Abstract

During a wide spread of airborne Coronavirus (the
COVID-19 pandemic), N95 respirators are highly required
for healthcare professionals to prevent themselves from
the infection. Due to their current shortage, other types of
certified respirators (e.g. KN95, FFP2, or KF94) from
international organizations outside the U.S. could be
substituted. Besides, two different types of surgical and
industrial respirators similarly were able to filter biological
particles such as bacteria and viruses. It was recommended
that both a company name and a code number on the
external side of the respirator be carefully checked before
use. If the shortage situation becomes more critical,
respirators should be reused three to four times after
having been sterilized by several methods.
