HD Filtration
Corteco offers a wide range of filtration solutions designed to provide clean air, reliable system performance, and long-lasting component protection. Backed by the filtration expertise of Freudenberg, our portfolio includes cabin air filters with micronAir particle and activated carbon technology, which support healthy air quality, even in demanding operating environments.
These filters are engineered to capture pollen, dust, soot, and other airborne particles that can cause discomfort or irritation to drivers and passengers. By maintaining cleaner air inside the cabin, Corteco enhances visibility, supports clear concentration during long work hours, and contributes to overall operating safety.
As a trusted provider of original equipment micronAir filters for the independent aftermarket, Corteco ensures every product meets strict quality standards. Each filter is produced according to original equipment standards and is designed to protect heating, ventilation, and air conditioning systems from premature wear by stabilizing airflow and minimizing contamination.

With the invention of the first cabin air filter in 1989, Freudenberg Filtration Technologies set a new standard for health and safety in vehicles. The proven micronAir particle filter provides reliable protection against fine dust, pollen, road dust, and bacteria. It effectively filters all PM10 particles (<10 µm).
This was followed by another innovation: the micronAir combi filter. Although the filter media of both micronAir cabin air filters are essentially identical, the micronAir combi filter has an additional layer of activated carbon to adsorb PM2.5 particles (<2.5 µm) such as odors and gases (e.g. benzene and ozone), which in turn is protected by a top layer.
This evolution of the cabin air filter has led to the latest addition to the Independent Automotive Aftermarket (IAM): the micronAir blue cabin air filter. Designed with 4 layers of filtration media, the latest addition to the micronAir cabin air filter range has the same characteristics as the combi filter, but also filters smallest PM1 particles (PM1 = <1 µm) such as viral aerosols. These particles are not only filtered, but also permanently trapped and deactivated by a bio functional layer.

More room for health with less energy
Electric motors require up to 75% less space than typical combustion engines. This opens up spaces to integrate entirely new air design concepts. Larger, multi-layer solutions offer the potential for better air in the vehicle cabin while reducing the energy consumption in electric cars. Freudenberg filters developed specially for circulating air, need about 15% less energy while maintaining the same high air quality.
