Breathe Clean Air



Mass Transit Clean Air

Bring back rider and operator confidence in public transportation by reducing airborne contaminants inside your fleet.


Our Metro Bus Solution


MERV-13 Equivalent Filtration

MERV-13 equivalent filtration helps capture pathogens, particulates, and other contaminants from recirculated air without reductions in airflow.



A high dose of UVC helps inactivate pathogens and contaminants caught in the filter and traveling through the moving airstream.


Reduces operating costs related to preventive maintenance by extending the time between filter changes.


Our solution is completely enclosed, ensuring no UVC light shines on occupants. No ions, chemicals or gases are released into the air that people breathe.

Equivalent Filtration

Our solution includes a MERV-13 equivalent filter with low pressure drop, high dust holding capacity. See our Bus Filtration Page for more information.


Public transportation is a necessity for many. As the economy continues to reopen it remains critical for transit authorities to create the safest environment possible and restore peace of mind for commuters. Despite the focus on surface disinfection, it is well understood that many pathogens like SARS-CoV-2 and influenza are primarily spread via airborne transmission. Public transportation environments are high people density spaces and often utilize low efficiency filtration designed to protect equipment, not clean the air commuters breathe. As a result, transit settings are high risk spaces that require intervention.

Customized Solutions

Our solutions are customized to meet the specifications of your fleet.

Patent pending Lumin-19 uses a combination of MERV-13 equivalent filtration and safe, effective, proven UVC to help continuously clean and disinfect the air recirculated throughout your transit vehicle. A filter only solution is also available.

UVC has been used for decades to help reduce the risk of airborne pathogen transmission and is a recommended solution by the CDC and ASHRAE to help supplement enhanced filtration in congregate spaces.

Our solution keeps UVC in an enclosure, helping to disinfect recirculated air, and prevents UVC from shining on occupants or materials.

Our solution does not emit deadly gases, chemicals, ions, hydroxyl radicals, ozone or other pesticides in the air people breathe.

Our solution is easily retrofitted onto existing buses, with or without an existing AC system, and requires very little maintenance.

Lumin-19 is a visible sign to the public of the commitment by the vehicle system's owners to their health and safety.
