The all-new Volvo XC90, which had its world premiere a couple of months back, would feature a bigger and more efficient multi-filter in the cabin. It is a part of the company's standard-setting CleanZone initiative through which it intends to control interior air quality and come up with relatively better driving environment for the wellbeing and health of the occupants.
This multi-filter is being designed exclusively for the SPA platform and the 2015 XC90 would be the first vehicle to showcase this technology. Due to this multi-filter, the drivers can now breathe more easily as majority of the microscopic, hazardous “fine dust” particles wouldn't be able to enter the car. 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. The results are impressive. In a car equipped with the new improved multi-filter, the amount of “fine dust” particles smaller than 0,4 μm can be as much as 70% less than in a car without the filter, according to a standardized component test. This is a significant improvement as studies have shown that dust particles smaller than 10 µm can cause a number of health problems, including difficulty breathing and lung infections.
“Up to 45 per cent of the industrialised world’s population is now suffering from some form of allergy or hypersensitivity. Over ten per cent has asthma. At Volvo, our commitment to safety goes well beyond safety belts and air bags. It’s about making sure that every minute you and your family spend in a Volvo is as safe as it can possibly be. That includes breathing,” says Peter Mertens, Senior Vice President Research and Development. “With this filter we are now at the forefront of the industry in terms of particle separation.”
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 and Gases and unpleasant odours.
