Filter the air you breathe on the plane
An ugly truth about air travel is the fact that there is very little fresh air brought into the cabin by airliner ventilation systems. Most of the air is continually recycled through hundreds of feet of ducting. The result is that the filtered air has to travel some distance through the system before it gets to you. Airline ventilation systems have filters in place, but not on the air nozzle above your seat.
The Solution: Plane Clean Air, a filter that you place on the air nozzle above your seat. The adjustable nozzle on the Plane Clean Air filter focuses the air and creates an air curtain that is similar to that of a clean room. The air curtain ensures that the air that you're breathing is 99.5% free of all airborne bacteria, viruses and allergens. Even though this product is a perfect fit for people whose immune system is challenged, it would undoubtedly help healthy travelers who get sick after spending 3 hours in an aluminum tube with hundreds of other passengers. You might get a few funny looks when you first place Plane Clean Air on the air nozzle, but it's worth it.
