MAHLE LAK 1730 Activated Carbon Cabin Air Filter

The MAHLE LAK 1730 is an activated carbon combination cabin air filter (also known as a cabin pollen filter or passenger compartment air filter) engineered to OEM specifications. Designed as a direct-fit replacement, it effectively cleans the air circulating through your vehicle's heating, ventilation, and air conditioning (HVAC) system before it reaches the cabin.

The LAK-series combi-filter features a three-layer sandwich construction: an activated carbon layer is bonded between two layers of non-woven filter media using a solvent-free heat fusion process. This design allows the filter to capture both particulate contaminants and harmful gases in a single element.

Key Features:

• Activated carbon layer eliminates harmful gases including nitrogen oxides (NOx), ozone, and sulfur dioxide (SO2)
• Pleated filter media traps fine particulates including pollen, dust, soot, tire debris, and brake dust
• Superior embossed and pleated media delivers high dirt-holding capacity with low pressure drop
• Premium sealing technology prevents bypass air and ensures leak-free operation
• Precise OEM-matched fit reduces blower motor load and protects the A/C system from contamination
• Helps prevent dangerous fogging of interior windows
• Produced using solvent-free ultrasonic welding — no harmful emissions from the filter itself

MAHLE recommends replacing cabin air filters approximately once per year. A clogged or failed cabin filter can cause interior pollutant levels to rise significantly compared to outside air, impacting driver alertness and passenger comfort. The MAHLE LAK 1730 is a premium OE-quality solution for maintaining clean, breathable air inside the vehicle.
