Key Features

• Dual-action cabin filtration media for particle capture and odor control

• Polyphenol-coated side helps trap and neutralize allergens
• Designed for passenger comfort and clearer in-cabin air quality
• OE-style replacement for select Audi HVAC filter applications

Product Details

Valeo’s ProtectMax line focuses on cabin air protection with a two-sided filter design. One side combines particulate media with active carbon to address dust, odors, and gases, while the other side uses a polyphenol coating to target allergens. This makes the Valeo cabin air filter a practical choice for Audi A4 and Audi A6 platform vehicles where HVAC filtration is part of routine maintenance. Cross-reference part numbers include Bosch 6025C and Gates 24765 for the same application.

What It Helps Address

• Dust and fine airborne particles entering the HVAC system
• Pollen and other inhalation allergens inside the cabin
• Unwanted odors from outside air intake
• Gases that can affect cabin air freshness
• Reduced HVAC airflow caused by a restricted filter
