Reply to comment by gerkletoss in UIUC Researchers propose a new way to get fresh water from seawater, without the disadvantages of traditional desalination. They say that a vertical “capture surface” that is 210 m wide and 100 m tall, could extract enough vapor floating above warm oceans to supply 500,000 people with freshwater by lughnasadh

Salt has a boiling point of nearly 1500C so it is only going to be present in air as an aerosol which again would be trivial to filter out. A coffee filter could probably get the majority of it.

Boiling and aerosols are not the only way for solids to end up in the air. For one thing, things that begin as aerosols can turn into vapor and leave airborne dust behind.
