DESCRIPTION

Product Overview

• Engineered for modern heavy-duty trucks, this premium cabin air filter ensures your interior HVAC system delivers clean, allergen-free air without restricting airflow. Featuring an electrostatically charged non-woven media layer, it traps up to 95% of airborne particles—including road dust, pollen, diesel soot, and fine debris down to 10 microns—protecting passenger respiratory comfort during long hours on the road.
  
• The optimized pleat design maximizes dirt-holding capacity while maintaining strong vent velocity for rapid heating and cooling. By promoting unrestricted airflow through your climate control system, this filter helps the defroster quickly clear windshield moisture on humid or frosty mornings, keeping your cabin environment fresh and clear year-round.

Key Features

• Utilizes a combination of specialized non-woven synthetic fibers to block road dust, pollen, soot, and airborne allergens before they enter the interior cab.
  
• Features static-charged fiber layers that capture microscopic dust and fine soot particles down to 10 microns without restricting blower motor airflow.
  
• High-flow pleat geometry maintains strong AC and heater vent velocity, allowing your truck's defroster to clear windshield condensation efficiently on cold, humid mornings.
  
• Guards your vehicle's blower motor, heater core, and evaporator coils against debris buildup, preventing costly climate control wear and unpleasant cabin odors.

Replacement Interval

• Replace the cabin air filter every 12,000–15,000 miles or once per year under normal conditions. For trucks operating in dusty, agricultural, construction, or high-pollen environments, replace twice annually to maintain fresh interior air quality and proper HVAC airflow.
  

FAQ

Q: Where exactly is the cabin air filter located on my 2020+ Silverado or Sierra HD truck? 

A: The cabin air filter is located directly behind the glovebox. Simply release the side retaining tabs on the glovebox door to lower it, unclip the rectangular access cover, and slide the old filter out. The entire replacement takes under 5 minutes with no special tools required.

Q: Is this the same cabin filter used in the 2015–2019 trucks? 

A:No. While the replacement process is similar, 2015–2019 trucks require a different sized filter. This CF185 filter is specifically engineered to fit 2020–2026 Chevy Silverado and GMC Sierra models (1500, 2500 HD, and 3500 HD).

Q: Can a dirty cabin air filter affect my truck's air conditioning and heating performance? 

A: Yes. A clogged filter severely restricts airflow through your vents, forcing the blower motor to work harder. This leads to increased fan noise, slower cabin cooling or heating, and reduced defroster efficiency on humid or cold days.

Q: Will this filter help block airborne soot and road allergens? 

A: Absolutely. The multi-layer synthetic media utilizes an electrostatic charge to capture up to 95% of fine airborne particles—including fine dust, road allergens, and diesel soot—keeping the air inside your truck clean and fresh.

Q: Combine this with the engine air filter for a complete respiratory service? 

A: The 2020-2025 Air & Cabin Combo covers both air filtration points in a single order. For the full 2020+ package with fuel and oil filters included, step up to Full Maintenance Kit.
