SAFE
ccording to the European Environment Agency, air pollution remains Europe’s most significant
environmental health risk. Many drivers are unaware that the majority of conventional vehicle air filters are designed to capture only dust and pollen. These filters do not remove harmful microscopic pollutants such as nitrous oxides (NOx) and sulphur oxides (Ox), which can accumulate to dangerous levels inside vehicles, endangering drivers without their knowledge. Harmful emissions are an

receives significant media attention, it is among the least harmful emissions to drivers. Carbon monoxide (CO), NOx and SOx pose far greater threats. For instance, CO, a product of incomplete combustion, is highly toxic to humans even at concentrations as low as 1% by volume. Additionally, nitrous oxide (N2O) is a potent greenhouse gas with 265 times the warming potential of CO2 over a 100-year timeframe. Mechanical filters in cars fail to
capture these harmful emissions, leaving drivers unaware since gases like CO and NOx are odourless. Harmful compounds like benzene and toluene are also a risk, as while the sale of these compounds are tightly regulated, their production by petrol and diesel vehicles remains largely overlooked.
