Looking for a washable fabric mask I wonder if the fabric type will really filter PM2.5 dust or not, try to find out.
Selected image Every shop said that it is a N95 model that can filter PM2.5 dust, but not quite sure. Who has any information?

Thank in advance.

People have studied this. Here is one example.

Just think. Robert Redford, head of the CDC, says that if we wear the masks for 6, 8, 10, 12 more weeks, we will completely eliminate Covid. In fact, he thinks that the mask is better than the vaccine. Lol. Watch this.
