SJ AUTO’S HIGHLY EFFECTIVE CABIN AIR FILTERS remove more than 90% of all pollen and road dust particles entering into the car cabin without inhibiting the flow of fresh air

They are designed to removed particle matter or soot from the exhaust of an engine. This particle matter in the exhaust results from the incomplete combustion of the fuel. In previous years, particle filters were not widely used, but in more recent times tightening regulations on emission levels of vehicles have encouraged an increase in demand for these filters.
