Heavy Duty Filtration
Corteco’s heavy duty filtration portfolio includes a wide selection of cabin air filters developed to perform reliably under harsh operating conditions. Designed for use in commercial vehicles, agricultural machinery, and off highway equipment, our particle and activated carbon cabin filters support clean air intake even in dust intensive and high emission environments.
Based on the proven micronAir filtration technology from Freudenberg, Corteco cabin air filters provide original equipment quality for the independent aftermarket. These solutions are engineered to meet the same performance and durability requirements found in original installations, ensuring consistent filtration efficiency and long service life in daily heavy duty operation.
Corteco cabin air filters help reduce exposure to pollen, fine dust, soot, and other airborne contaminants that can cause irritation and fatigue during long working hours. By maintaining cleaner air inside the cab, they support operator comfort, clear visibility, and safe operation in challenging conditions such as field work, construction sites, and transport routes with high exhaust levels.
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.
