The idea of this product is to filter and purify airplane air, which anyone who flies often knows can get very stale and very uncomfortable very quickly, depending on how large the plane is and how many people are on the flight. Just attach the Plane Clean Air Filter to that little air vent that's right over your seat (the one next to the "summon flight attendant" button) and the filter cleans the air and directs the flow of air straight at your face.

The filter creates a "clean air curtain" that takes fresh air and delivers it straight to you, and somehow repels bacteria, viruses, allergens, or other irritants in the all-too-often stuffy air inside a jet. Personally, I don't have much faith in a product like this keeping viruses and bacteria out of the air that you breathe; you have a much higher chance of getting ill from bacteria picked up on items that you touch, or from people sneezing or coughing on you than from random airplane air.

Even so, I know firsthand how stuffy and stale cabin air can be, and I'd like something like this not so much to keep my air clean, but to blow a constant stream of air on my face during an entire flight. Now the real trick will be convincing a flight attendant not to report you to Homeland Security for "affixing a suspicious item to the air vent."
