Corteco 2128303001 micronAir Cabin Air Filter

The Corteco 2128303001 is a direct-fit micronAir® cabin air filter (also known as a pollen filter, interior air filter, or HVAC filter) engineered as an OE-equivalent replacement. As the aftermarket distribution arm of the Freudenberg Group — the original inventor of the cabin air filter — Corteco delivers factory-level filtration performance for the independent aftermarket.

This particle-type cabin air filter is designed to keep the air inside your vehicle's passenger compartment clean and free of common airborne contaminants. It works within your vehicle's heating, ventilation, and air conditioning (HVAC) system to trap pollutants before they reach the cabin.

Key Features:

• OE-quality micronAir® filtration media — identical in specification to filters used by original equipment manufacturers
• Effectively captures pollen, fine dust, road dust, soot, and other particulate matter
• Helps prevent window fogging by maintaining two-layer airflow filtration
• Protects and extends the service life of the HVAC blower motor and evaporator
• Reduces allergens and irritants that cause sneezing, watery eyes, and breathing discomfort
• Direct OEM-style fit — no modifications required for installation
• Detailed installation instructions included for fast, straightforward replacement

Corteco cabin air filters are trusted worldwide, with nearly one in two new cars equipped with cabin air filtration already using Freudenberg's micronAir® technology. Replacing your cabin air filter at regular service intervals ensures optimal airflow, cleaner cabin air, and improved driving comfort and safety.
