Only marginally relevant, this is one reason I use swamp coolers in my home. My windows are open 24/7, 4 months of the year. I hear the birds in the morning and it’s so much more pleasant than shutting in an air conditioned box, in my opinion

Do you not get massive amounts of dust?

Why would opening the windows result in dust, except where there a lot of dust outside (near a construction site)?

swamp coolers work - imples desert - implies dust
