MAHLE LA166 Particulate Cabin Air Filter - Pollen & Dust Filter

The MAHLE LA166 is an OE-quality particulate cabin air filter designed to keep the air inside your vehicle's passenger compartment clean and free of airborne contaminants. As a particulate filter, it captures fine dust, pollen, industrial fallout, soot, and other microscopic respirable particles before they enter the cabin through the heating, ventilation, and air conditioning (HVAC) system.

Key Features:

• Particulate filtration — blocks fine dust, pollen, industrial particulates, and airborne debris from entering the cabin
• OE-equivalent quality — engineered to meet original equipment specifications for reliable fitment and performance
• Reduces HVAC system load — low flow resistance minimizes strain on the blower motor and protects heating and A/C components from contamination
• Prevents window fogging — helps maintain proper air circulation to reduce dangerous windshield and window fogging
• Accurate fit — precision-engineered filter element prevents bypass air, ensuring all cabin air passes through the filter media
• No harmful emissions — manufactured using solvent-free production methods including ultrasound welding technology

MAHLE is one of the world's leading manufacturers of more than 100,000 OE and aftermarket parts, supplying cabin air filters directly to major automotive manufacturers globally. The LA166 particulate filter is the base filtration version; the activated carbon upgrade equivalent (LAK 166) is also available for odor and gas removal. Replacement is recommended every 15,000–30,000 miles or once per year under normal driving conditions.
