So before we get to our reviews,there are a few dos and don'ts to know. UNSW epidemiologist Dr Abrar Ahmad Chughtai,who has writtena paper on cloth masks for journalEmerging Infectious Diseases,says when buying a cloth mask,look for one that will fit snugly around the face,covering the nose and mouth.
The mask should also have at least two or three layers of material in a tight weave,he says."If you can see through,the thread count is too low."Victorian authorities suggest the ideal mask has three layers,including a water resistant outer-layer.

Chughtai adds that cloth masks that mix threads,for example cotton and silk,can offer better filtration and may feel more comfortable.
People are also urged to avoid masks with holes or a valve as it can result in breathing out the virus.
"You just need to have a standard mask that is fitted properly and managed properly,"Dr Chughtai says.
Swinburne University's dean of health sciences,Professor Bruce Thompson,says hands must be sanitised before putting on a mask and after taking it off – and when wearing it,avoid touching it.
