I just did another cursory review of the article. Can you please point out where it states that cloth mask protect unless worn improperly? It seems as though you are reading the article with extreme bias and drawing conclusion about the article that simple are not there. However, I only did a cursory review so maybe I am wrong. I did not read that cloth mask are effective unless worn improperly. Please post the quote that states that. What I read basically stated that cloth mask are ineffective and might even be the cause of you getting Covid-19 if you touch the outside of the mask after wearing it.The only thing I agree with is the flase sense of security as illustrated by the article pointing out that people wearing masks improperly are not protecting. That is self evident and a major risk. the article mentions risks of reusing the cloth masks, touching them and touching your face, or not disposing of them properly...these are all factually instances of people IMPROPERLY using masks. There are lots of sources of medical staff tlaking about constantly washing their hands after taking off each piece of PPE and disposing of it correctly or for cloth masks, treating them the same way and cleaning them.
We cannot put down the effectiveness of masks due to the idiots who fail to use them properly and touch their mask and then touch their face, their phone or fail to wash their hands or interact with other people with them not covering their nose etc..

Below is the quote I think that you are referring to:
Self-contamination through repeated use and improper doffing is possible. A contaminated cloth mask may transfer pathogen from the mask to the bare hands of the wearer.
Below are several other quotes from the article:
Conclusion: Wearing masks will not reduce SARS-CoV-2.
- Cloth masks will be ineffective at preventing SARS-CoV-2 transmission, whether worn as source control or as personal protective equipment (PPE).
Filter efficiency was measured across a wide range of small particle sizes (0.02 to 1 µm) at 33 and 99 L/min
