So how do we possibly use this? What if I soak regular mask (I have a cache of simple ones, not surgical) in a strong saline solution and then dry it - how much

So how do we possibly use this? What if I soak regular mask (I have a cache of simple ones, not surgical) in a strong saline solution and then dry it - how much effective is it going to be against flu and 2019-nCoV?

Without testing it, it seems unlikely you would get enough airflow. If it works at all then only through a perfectly sealing mask, as others point out. Maybe treating the filter of a cheap air purifier could have positive effects against airborne diseases indoors?
