Activated Carbon Cabin Air Filters

AirTechnik engineers and designs our activated carbon air filters with quality, performance, durability, and cost in mind. AirTechnik cabin air filters keep your vehicle clean, smelling fresh, and help prevent particles from circulating in your vehicle to provide a clean and comfortable breathing environment. Cabin air filters are considered the front line of defense and provide a filtering barrier from outside particles and elements that may enter the vehicle. Our activated carbon filters can remove dust and other particles ranging from 5 to 100 microns. These filters also adsorb exhaust gas and road dust, providing a cleaner breathing environment inside the vehicle.

Driver and Passenger Health

Cabin air filters help provide a steady source of clean air to the vehicle, improving breathing comfort for both passengers and the driver.

Breathe Clean Air

Roadside air often contains exhaust gas, dust, and smog that can be concentrated up to 2 to 6 times more inside a vehicle compared to outside air. A clean cabin air filter ensures fresher air circulation for your comfort and safety.

Simple and Fast Replacement

When cabin filters become clogged with debris, they obstruct clean air circulation. Replacing the cabin air filter takes less than 15 minutes and should be done every 12,000 miles or annually. Installation instructions are included with each filter.

Installation Instructions

1. Open hood and locate the two filter covers on either side of the vehicle.
2. Unhook the wire latch located on the front of the filter cover by pulling forward.
3. Lift open the cover and carefully clean debris from the housing.
4. Remove dirty filter and install clean filter.
5. Replace and secure filter covers.
