Does the type of mask matter?

        

• Studies have compared various mask materials 
• The most important consideration is comfort. 
• The best mask is one you can wear comfortably and consistently. 

Surgical masks are generally more protective than cloth masks, and some people find them lighter and more comfortable to wear.

Experts have cautioned against N 95 masks with valves

• They are commonly used in construction to prevent the inhalation of dust
• But they do not protect the people around you. 
• The valve is one- way. It closes when the person breathes in, but opens when the person breathes out, allowing unfiltered air and droplets to escape. 

• The city of San Francisco has specified that masks with valves do not comply with the city's face covering order.

The bottom line

Any mask that covers the nose and mouth will be of benefit.
You can use a handkerchief or a dupatta or a gamcha

The concept is risk reduction rather than absolute prevention,”
