Cloth Masks May Not Be Enough to Protect Against New COVID-19 Strains

The highly contagious COVID-19 variants have experts urging everyone to wear much more protective masks. For months, much of the public has worn a bandana or a cloth mask, but now it’s being said that what worked in the past may no longer be good enough. Because of the variants, experts are now pushing for people to wear KN95 or KF94 masks. KF94 masks and KN95 masks have between three and five layers of filtration. Once difficult to find, they are now readily available online.
