N95 masks work. Well designed, well fitted, correctly worn, hygienically cleaned cloth masks probably work okay, though good evidence of this is still limited and based largely upon assumptions. From my own observations, the overwhelming majority of people are wearing a mask of poor quality and/or in a manner which the scientific consensus couldn't possibly agree was effective. And I doubt most people are washing them with soap and water every single day.
If we're not going to mandate an effective mask, I honestly don't see what the point of the mandate is. It makes as much sense to me as seatbelt mandates accepting a knitted scarf as an acceptable seatbelt.

"Cloth face masks show minimum efficacy in source control than the medical grade mask. The efficacy of cloth face masks filtration varies and depends on the type of material used, number of layers, and degree of moisture in mask and fitting of mask on face."

"The use of cloth masks during the coronavirus disease (COVID-19) pandemic is under debate."
"Until a cloth mask design is proven to be equally effective as a medical or N95 mask, wearing cloth masks should not be mandated for healthcare workers."
"In 2015, we conducted a randomized controlled trial to compare the efficacy of cloth masks with that of medical masks and controls (standard practice) among healthcare workers in Vietnam. Rates of infection were consistently higher among those in the cloth mask group than in the medical mask and control groups."

"Your cloth face mask isn't protecting you against the coronavirus variant omicron, health officials say. As common as cloth face masks have become, health experts say, they do little to prevent tiny virus particles from getting into your nose or mouth and aren't effective against the new variant."

"They found that the effectiveness of the masks varied widely: a three-layer knitted cotton mask blocked an average of 26.5 percent of particles in the chamber, while a washed, two-layer woven nylon mask with a filter insert and metal nose bridge blocked 79 percent of particles on average. Other masks scored somewhere in between."
