In practice many N95s filter over 99% of particles including around the important sizes for COVID. I think of them like drinking coffee from a paper disposable cup: convenient in many ways but more expensive over time and a crappier experience than ceramic. Lots of people will do it. I do however use a 7502 with 2297 filters for high exposure and GVS Elipse for medium exposure like grocery store.
