Which filter is best at removing traffic pollution?

Contamination from airborne traffic pollution is divided into two types: exhaust particulates and gasses, such as nitrogen dioxide (NO2).

To remove both types of airborne contamination from traffic pollution, make sure to use a HEPASilentâ„¢ filter with activated carbon. Filters with activated carbon are the only kind of filter that will adsorb the harmful gases and keep them locked away.
