My wife and I, plus my side of the family, skipped cloth masks altogether. We managed to acquire a load of KF94 (Korean N95 equivalent) from friends and relatives in Korea and used them (and continue to use them). Neither my parents (dad is early 70s, mom is late 60s) nor my wife and I have gotten covid yet*
On the other hand, my wife's side of the family quickly abandoned use of the KF94s and switched to cloth masks. All of them got covid in late 2020, and all of them just got omicron again.
Everyone in both sides of the family got vaccinated plus boosters.
* While obviously not 100% certain, we got tested frequently both using in-home antigen kits and PCR. I was probably the most at risk due to having changed jobs in early 2021 where everyone was told to come back to the office. However my employer provided free daily PCR testing, which I took advantage of. Have had 100% negative daily results thus far...
