Product Overview

The Nissan cabin air filter, OEM number AY684-NS018 (AY684NS018), is a replacement air conditioning filtration component for selected Nissan March, Micra, Note, and Latio vehicles. Also known as an AC filter or pollen filter, this component helps capture airborne dust, pollen, and other particles before air enters the passenger compartment through the heating, ventilation, and air conditioning (HVAC) system.

This cabin filter is listed for compatible Nissan March / Micra K13, Nissan Note E12, and Nissan Latio N17 applications. By helping reduce airborne contaminants within the ventilation system, the filter supports cleaner cabin airflow and helps limit dust accumulation on HVAC components.

Over time, dust and debris collect within the filter media, potentially restricting airflow and reducing ventilation performance. A clogged cabin air filter may contribute to weak airflow, unpleasant odors, and reduced passenger comfort. Regular inspection and timely replacement help maintain effective filtration.

GSK Auto supplies AY684NS018 cabin air filters for automotive parts importers, wholesalers, distributors, fleet maintenance suppliers, and repair shops worldwide. We support bulk purchasing, flexible wholesale cooperation, private label packaging, and product compatibility assistance.

What Is a Cabin Air Filter?

Function: A cabin air filter captures airborne dust, pollen, and other particles from air passing through the vehicle's heating, ventilation, and air conditioning system. It helps improve the cleanliness of air entering the passenger compartment.

Working Principle: When the ventilation blower operates, air passes through the cabin filter media. The filter traps airborne particles while allowing filtered air to travel through the HVAC ducts and into the passenger compartment. Proper filtration depends on the media, sealing performance, airflow resistance, and correct installation.

Importance: A properly maintained cabin air filter helps keep the vehicle's ventilation system cleaner and supports normal air conditioning airflow. Replacing a contaminated filter can help restore airflow where filter blockage is the cause of reduced ventilation performance.

Common Failures & Signs: Dust accumulation, clogged filter media, moisture exposure, damaged filter edges, and incorrect installation can reduce filtration performance. Common signs include weak airflow from the vents, unpleasant cabin odors, increased blower noise, visible dust buildup, and a heavily contaminated filter during inspection.
