MAHLE LA 1373 CareMetix Multi-Layer Cabin Air Filter

The MAHLE LA 1373 is a premium cabin air filter, or cabin pollen filter, engineered to deliver cleaner, healthier air inside your vehicle. Built to original equipment (OE) standards, this filter integrates seamlessly with your vehicle's heating, ventilation, and air conditioning (HVAC) system to protect both passengers and system components.

The LA 1373 is part of MAHLE's exclusive CareMetix multi-layer filtration platform, offering an industry-leading five-layer construction for comprehensive air purification:

• Layer 1 – High-Performance Particulate Layer: Captures fine dust, pollen, soot, brake dust, and tire debris before they enter the cabin
• Layer 2 – Molecular Layer: Targets microscopic airborne contaminants at a molecular level
• Layer 3 – Engineered Activated Carbon Layer: Adsorbs harmful gases including nitrogen oxides (NOx), ozone, and sulfur dioxide (SO2)
• Layer 4 – Bio-Functional Layer with Activated Carbon: Provides an additional barrier against biological and chemical pollutants
• Layer 5 – Protective Layer: Shields the filter media and ensures structural integrity throughout the service life

MAHLE cabin air filters use a precisely pleated filter media design that maintains low airflow resistance, reducing strain on the blower motor while maximizing filtration efficiency. Accurate dimensional fit prevents bypass air leakage, ensuring every cubic foot of air passes through the filter media.

Key Features:

• OE-quality design and materials for direct-fit replacement
• Five-layer CareMetix construction for superior multi-contaminant filtration
• Filters particulates, pollen, allergens, fine dust, and harmful gases
• Protects HVAC system and blower motor from contamination and premature wear
• Improves air circulation and helps prevent window fogging
• Solvent-free, ultrasonic-welded construction — no harmful emissions from the filter itself
• Engineered for long service life with high dirt-holding capacity

MAHLE recommends replacing cabin air filters every 15,000 to 30,000 miles, or at least once per year, to maintain optimal cabin air quality and HVAC performance. The MAHLE LA 1373 is the trusted choice for drivers who demand OE-grade filtration and proven protection.
