Corteco Cabin Air Filter Set

Corteco micronAir® Cabin Air Filter Sets: OE Quality for Cleaner In-Cabin Air

When it comes to the air you breathe inside your vehicle, Corteco occupies a uniquely authoritative position. Corteco's cabin air filtration products are backed by the engineering heritage of Freudenberg Filtration Technologies — the company credited with inventing the first cabin air filter in 1989. That legacy of innovation has made Corteco's micronAir® filter line a benchmark for original equipment (OE) quality in the independent aftermarket.

More than every second new car worldwide is equipped with a micronAir® filter from Freudenberg, and these OE filters are supplied to the independent aftermarket by Corteco. That means when you install a Corteco Cabin Air Filter Set, you're often getting the same filtration technology that came fitted in your vehicle from the factory.

The micronAir® Filter Lineup

Corteco's cabin air filter sets are available in several distinct configurations, each engineered for a specific level of protection:

• micronAir® Particle Filter: Corteco's micronAir® particle cabin air filters ensure pristine air quality and improved visibility, designed to remove pollen and other PM10 (<10 µm) particles from the air, extending the life of your air conditioning and ventilation system.
• micronAir® Activated Carbon Filter: Corteco's micronAir® activated carbon cabin air filters remove pollen, soot, and other PM2.5 particles (<2.5 µm), extend the service life of your air conditioning and ventilation system, and prevent misted-up windows. They also protect passengers from exhaust fumes and ozone, making unpleasant odors a thing of the past while increasing driving comfort and minimizing health risks.
• micronAir® Blue Filter: micronAir blue cabin air filters provide active protection by significantly reducing the concentration of viral and microbial aerosols. The filter allows you to breathe freely during every journey, with the assurance of its vegan composition — both the filter and adhesives used are 100% vegan, and neither the final product nor its components have been tested on animals.

Multi-Layer Filtration Technology

The micronAir® combi filter builds on the particle filter's media with an additional layer of activated carbon to adsorb PM2.5 particles (<2.5 µm) such as odors and gases including benzene and ozone, which in turn is protected by a top layer. The micronAir blue takes this further, designed with 4 layers of filtration media.

Corteco's filtration portfolio offers a wide selection of cabin air filters with approximately 850 different variations, with an extensive range of particle and carbon activated filters to suit different vehicle models and specifications. Whether you drive a European luxury vehicle like a BMW or a more common domestic make, there's very likely a Corteco cabin air filter set engineered to fit your exact application.

Why Choose a Corteco Cabin Air Filter Set?

Replacing your microfilter annually or every 15,000 miles keeps dust, pollen, soot, and pollution at bay, and the OEM-quality multilayer, moisture-resistant material provides nearly 100% filtration efficiency. Corteco cabin air filters are designed to eliminate common irritants that cause discomfort such as sneezing, watery eyes, runny nose, and breathing difficulties — and by providing cleaner air, Corteco enhances visibility and contributes to improved road safety for drivers and passengers.
