How N95 And KN95 Respiratory Masks Protect Against Pandemic COVID-19?


Since the outburst of 2002 SARS [severe acute respiratory syndrome], the popularity of respiratory masks has steadily increased. Scientists have been debating whether a respiratory mask will help to avert the spread of the virus, since the influenza pandemic in 1918 to 1920.

Today, the majority of people agree that high-quality respiratory face masks offer good infection control, which includes regular hand sanitizing or washing. However, normal masks cannot protect against pollution and germs.

FFR or filtering face respirators are also termed as disposable respirators. These are subject to specific regulatory standards, which define the needed performance characteristics and physical properties. During emergencies or pandemic, the healthcare agencies refer to these standards while recommending facemasks like certain public must use FFP2 or N95 or KN95 masks.

Social distancing is the best way to avoid getting exposed to coronavirus. Another best practice is to wash hands for 20 seconds regularly and avoid touching surfaces as much as possible.
