Infection Risk in Transportation

Passengers in most forms of transportation are susceptible to the germs of the people around them, and frequently touched surfaces represent additional opportunities for the spread of communicable illness. Cleaning these spaces can be problematic, because there are so many surfaces requiring sanitizing, and any time spent to decontaminate is time spent not in transit.

  • Sick passengers contaminate the air as they exhale, cough, or sneeze bacteria or viruses

  • Germs can spread via contact with commonly touched surfaces such as handles, seats, and airline trays

Colony Forming Units in Transportation

A way to estimate the microbial content of air and surfaces, colony forming units (CFU) can show how contaminated a space can be. Clean and acceptable levels of surface contamination in schools, public buildings, and workplaces is under 5 CFU/sq. cm

The New York City Subway was tested with surface swabs and shown to have and average of 2,000,030 CFU/sq. inch

Airline tray tables were similarly tested and shown to have 2,155 CFU/sq. inch

airPHX Technology in Transportation

airPHX technology is a proactive strategy for continuously cleaning these public spaces, sanitizing the air and surfaces

  • Airlines deploying airPHX can create a healthier environment that lowers risk of spreading illnesses and reduces sick days for staff

  • The constant decontamination effects of an airPHX device can clean a subway car of microbes spread by passengers


airPHX technology deployed in transit makes a safer environment for passengers and staff.
