2. Airline Travel
You may be thinking, "why on earth would I get on an airplane right now?" The thought of being in a narrow tube with a bunch of strangers seems counterintuitive but it really is safer than you think.
According to MIT Medical, "For starters, the air quality on a commercial airliner is actually quite high, with the air volume in the cabin being completely refreshed every two to four minutes. Air flows into the cabin vertically — it enters from overhead vents and is sent downward in a circular motion, exiting at floor level. Once air leaves the cabin, about half is dumped outside, and the rest is sent through HEPA (high-efficiency particulate air) filters, similar to those used in hospitals, before being mixed with fresh outside air and entering the cabin again.
There is real and proven evidence that masks are effective in this situation.
