The quality of the air we breathe during daily travel plays a huge role in our short- and long-term wellbeing and quality of life. In public transportation, the air in the common space shared by commuters causes disease transmission and pollution exposure.

B-SAFER™ System for Cleaner Vehicular Cabins


Numerous studies indicate the increasing concentration of fine particulate matter, black carbon particles, and other gaseous pollutants in the cabin air as a bus travels along its commute. Carbon dioxide accumulates in cabins on crowded and idling buses due to limited ventilation. Various other traffic-related pollutants (TRP)’s also accumulates inside bus cabins through intake of the polluted air amid traffic. Additionally, viruses and bacteria are exhaled, sneezed, and coughed into the air constantly by the bus passengers and drivers.

The B-SAFER™ System contains a supercharger, powered by the bus, to bring and circulates clean air inside bus cabins, eliminating biological contaminants and with a catalyst, chemical pollutants. Testing has been conducted on a prototype system to demonstrate a reduction in traffic-related pollutants.

Trains and subway

Train cars are difficult to ventilate with pure air, particularly in subway settings. Recirculating the internal air through a B-SAFER™ unit will substantially improve air quality, reduce the spread of airborne viruses and bacteria, and can also reduce the number of Volatile Organic Compounds (VOC’s) and organic particles from diesel exhaust. Studies have illustrated that train cars can contain more than 15 times the normal level of exhaust pollutants when the diesel locomotive pulls the coaches (in the front). Moreover, risk of infection or disease transmission is very high on subway and rail coaches where people are within proximity (especially high risk with flu viruses in the fall and winter months).

Other Areas


Aircraft cabins are notorious for the spread of cold or flu viruses. The B-SAFER™ System can be designed to integrate into the air handling systems of aircraft. The improved air quality onboard will have a positive effect on the health of both passengers and crew, while also helping to mitigate the risk of infection spread during long flights.

Ships & Naval Transport

The B-SAFER™ System can be scaled and configured to provide clean air for large naval vessels and other maritime transport vehicles. Hospital ships can take advantage of the isolation and prevention capabilities by manipulating the airflow for quarantine units as well as operating rooms. B-SAFER™ also offers a highly effective method for mitigating airborne viral outbreaks on cruise ships.


SUV & Commercial trucks

In smaller passenger vehicles such as SUVs and commercial trucks with sleeping quarters on-board, exhaust and other environmental pollutants can tend to accumulate and recirculate inside the smaller cabin. Recirculating the internal air through a B-SAFER™ unit will substantially improve air quality, reducing the number VOCs and organic particles present in the cabin.
