The invisible menace: NO2 in the air we breathe

Nitrogen dioxide (NO2) is one of the nitrogen oxide pollutants produced by combustion processes. The presence of NO2 in urban air is mainly due to traffic. The proportion of NO2 in vehicle exhaust is considerably higher in diesel vehicles because their exhaust after‑treatment systems increase the oxidation of NO, leading to higher NO2 emissions.

Looking to the future

Cabin air filters are already ensuring optimal air inside cars. They protect against fine dust, pollen, bacteria and harmful pollutants in the air. In this interview, Dr. Jörg Sievert, member of the executive management at Freudenberg Filtration Technologies, explains why cabin air filters will continue to grow in importance.

From idea to success story

How micronAir cabin air filters took over the automotive world: These days, practically every car in the world has a cabin air filter as a standard feature. In times of high fine dust counts and smog, it is hard to imagine that just a few years ago this wasn’t the case. A trip through time.

New ideas for air design in cars

Freudenberg Filtration Technologies is the global innovation partner in the development of first-class cabin air filters for the automotive industry. As inventor of the cabin air filter roughly 30 years ago, we have years of expertise that form the ideal basis for producing filter media of the highest quality.

From inquiry to delivery

What does the development of an individual filter actually look like? In other words, the exact filter that could ensure clean air inside your new car model. What happens between the initial inquiry and installation in the vehicle? We offer you an exclusive look.

In search of good air

We only notice how valuable clean air is when it is absent. When particulate matter and smog determine our lives in the cities or the countryside and endanger the health of millions of people. So we decided to search out some unique places where you can breathe deeply without a care.

Fresh air from the can

Carefree breathing of clean air should actually be a matter of course. But not only asthmatics and allergy sufferers have a hard time. Many city dwellers are also increasingly suffering from the growing smog load. Several providers have recognized the need. They operate ‘air-farming’ – and sell air from the can.
