Cleaner air quality in the new Volvo XC90 cabin

By introducing a larger, more efficient multi-filter in the cabin, Volvo Cars continues to refine its standard-setting CleanZone initiative. Drivers can breathe easier because most microscopic, hazardous 'fine dust' particles will now be prevented from entering the car.

The multi-filter was designed especially for the SPA platform and will first appear in the all new XC90. It features a larger design that intercepts more particulates and pollen, as well as a layer of active charcoal that effectively removes a host of contaminants that can impact the health of drivers.

In a car equipped with the new improved multi-filter, the amount of 'fine dust' particles smaller than 0.4 micrometres can be as much as 70 percent less than in a car without the filter, according to a standardised component test.

This is a significant improvement as studies have shown that dust particles smaller than 10 micrometres can cause a number of health problems, including difficulty breathing and lung infections.

The filter is one element of Volvo's state-of-the-art Interior Air Quality System (IAQS). Another element is a sensor that monitors the incoming air for noxious substances. If the level of harmful substances becomes too high (such as when driving through a tunnel), the car's air intakes will automatically close. Together, the multi-filter and sensor keep out a number of harmful and irritating pollutants, including nitrogen oxides, hydrocarbons, ground-level ozone, gases and unpleasant odours.
