Chemistry keeps the air clean

The air around us has a big impact on our daily lives. In fact, recent studies have shown that air pollution can increase the risk of breathing problems while we sleep. Our catalytic converters reduce harmful emissions from cars and industries. It’s chemistry that keeps our air clean.

Chemistry of clean air

Smog is formed by a large number of fine particles floating in the air. These particles come from many sources but mostly from transportation and industry. The good news is air pollution can be fought with chemistry.

For more than 50 years, BASF has been developing solutions for clean air, including the invention of the catalytic converter for automobiles in 1970. Catalysts remove up to 99% of pollutants from the air we breathe. They help reduce harmful emissions from cars and industries so the oxygen around us is cleaner and safer to breathe.

From the minute we wake up to the moment we go to sleep, our lives are impacted by the quality of air we breathe. That’s why we’re constantly developing new, cleaner air solutions that, even if not seen, make our lives better.  


1. Rise and shine

Our catalysts help ensure the air around us is cleaner and safer to breathe. Recent studies have shown that breathing cleaner air can lead to a better night’s sleep.  

2. Driving

Worldwide, there are more than 1.4 billion motor vehicles on the road. Our catalysts – which are incorporated into the exhaust systems of cars, trucks, motorcycles, and other vehicles – are designed to reduce harmful emissions.

3. Flying

Our quest to improve air quality isn’t focused on just motor vehicles and buildings. We also offer products designed to improve air quality in commercial aircraft cabins by reducing the harmful ozone found at high altitudes.

4. Dining out

We have also developed systems that work in parallel with air conditioning in commercial buildings, to ensure the air you breathe will be cleaner and safer.
