Home Office Ventilation - Suggestions?

[white_s2k]

Thanks Wharf_Rat and Simple1.

I'm looking into the best way to set up the box fan for the window. I'd like to keep it about halfway shut to avoid losing too much cool air, especially during these warmer months.

Also researched a bit about the ozone units. Seems like a great way to clean out the room after I'm done working for the day.

Thanks!
