Oof, assuming indeed "95% filtering", PM2.5 is still going to be around 15, which is the recommendation for staying under... But that's still a huge improvement. There's going to be some chemical contaminants those masks won't be able to do that much about, but, nonetheless, huge improvement.
If you can, elastomeric respirator with P100 filter will be even better, especially combined with a charcoal chemical absorption filter.
