Lumin-Air announced it is providing MERV-13 filters to improve the air quality in school buses and mass transit vehicles.
In the Centers for Disease Control and Prevention’s Feb. 9, 2021, update on Ventilation in Buildings, they state, “CDC recommends using the highest efficiency ventilation filters possible, without having detrimental effects on overall HVAC system performance. ASHRAE, has similar guidance, however, they recommend a minimum filtration efficiency target of MERV 13, provided there are not substantial negative impacts on the HVAC system performance and occupant comfort.”
“MERV-13 air filters will provide an additional level of protection in high density spaces like school buses and mass transit vehicles where the density of people can be greater than in buildings. Improved filter efficiency will help mitigate the airborne transmission of harmful pathogens like SARS-CoV-2,” Lumin-Air’s Dan Fillenwarth says.
MERV-13 air filters are high efficiency filters that capture pollen, allergens, molds, bacteria, viruses and other particles that are missed with less efficient air filters.
“The challenge is to improve filtration without adding additional pressure drop that transit ventilation systems can’t handle. So, we provide a polarized media filter with the efficiency of a MERV-13 filter, but the low pressure drop of a typical MERV-4 bus filter. Independent certified airflow tests on a school bus show no airflow decrease with our MERV-13 equivalent filters compared to standard MERV-4 bus filters,” says Fillenwarth.
Andrew Desmarais of Lumin-Air adds, “Another benefit of our filters is that the dust holding capacity is several times that of a typical bus filter, which allows the duration between filter changes to be extended, and replacement filter media is very economical.”
Lumin-Air’s MERV-13 air filters are a perfect complement to their UV retrofit, or they can be provided as a stand-alone improvement for any bus, the company says.
