First, please remember: it's much better to wear a mask than nothing against COVID-19.

For general people (not medical staff), the mask with best proformance is 3-layer masks.

Moreover, people shoud avoid to use below masks:

In terms of filtering effect, neck guards and headscarves have the worst effect as masks, mainly these are made of thin and porous materials, which are too loose to filter out potentially harmful particles

Two-layer 100% rayon masks are also one of the worst masks tested in the market
