I am unfamiliar with any updated guidance stating that anything less than an N95 was ineffective (although efficacy does vary by fit and construction) or any guidance where they ever said that N95 masks were ineffective. I would love to see a source for these claims as when I search for the most up to date guidance from the CDC, I still see them providing information maintaining the same perspective on masks. |

The CDC Is Finally Acknowledging That N95 Respirators Work Better Than Cloth Masks
"The Centers for Disease Control and Prevention (CDC), whose previous advice about face coverings as a safeguard against COVID-19 paid little attention to large differences in the effectiveness of different mask types, recently revised its guidance to acknowledge that N95 respirators work better than reusable cloth masks or disposable surgical masks. As with earlier changes in CDC guidance, it is not exactly clear why the agency waited so long to highlight useful information about COVID-19, although the spread of the highly transmissible omicron variant may have something to do with it."
