Not true...it's just not as good as the N95 masks.
Wearing masks is doing more harm than good, because cloth masks are being reused, laid down on unsanitary surfaces, and recycling bacteria from the wearer.
Disposable mask, the same. Being reused, laid down on unsanitary surfaces, and recycling bacteria from the wearer.
Also, if they are not being reused, they are thrown onto the ground in the store's parking lot, trashing the environment and expecting store workers pick up these dirty mask from the ground...
