The pollen particle filter traps dust, pollen, dirt, and airborne particles before they enter the cabin through the ventilation system. It helps improve cabin air quality, protects the HVAC system from debris, and supports effective heating, ventilation, demisting, and air conditioning performance.

Functions
• Filters incoming cabin air
• Helps trap pollen, dust, dirt, and airborne particles
• Supports cleaner air inside the vehicle
• Helps protect the HVAC blower and ventilation system
• Supports efficient heater and air conditioning airflow
• Replaces dirty, blocked, damp, or damaged cabin filters
• OE Match replacement for routine service and maintenance.

Why Replace This Part?
Pollen particle filters become blocked with dust, pollen, leaves, moisture, and road debris over time. A dirty or clogged filter can reduce airflow, cause musty smells, misted windows, poor demister performance, increased blower noise, or reduced heating and air conditioning efficiency. Replacing the filter helps restore clean airflow and improves cabin comfort.

When to Replace This Part
•  Cabin airflow from the vents is weak
•  The ventilation system smells musty or stale
•  Windows mist up more easily than normal
•  The heater, demister, or air conditioning feels less effective
•  The blower motor sounds louder due to restricted airflow
•  The filter is dirty, damp, clogged, or overdue for service
•  Routine service or cabin filter replacement is being carried out.

Where it fits on the car
This pollen particle filter fits within the cabin ventilation / HVAC intake system. It filters air before it enters the passenger compartment through the heater and air conditioning system.
