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.

OEMatch Pollen/Particle Filters — Service Ready, Reliable Running
Porsche cabin air quality depends on effective pollen and particle filters that trap dust, pollen and fine particulates before they enter the ventilation system. Regular replacement keeps the interior fresh, reduces allergens for occupants and helps maintain consistent HVAC airflow and operation for Porsche models.
Understanding OEMatch Pollen/Particle Filters
OEM (Original Equipment Manufacturer) parts are made by the same company that produced your Porsche’s original pollen/particle filters.
OE (Original Equipment) refers to parts matching original specifications for the pollen/particle filters and may be supplied by alternative manufacturers. Aftermarket parts offer alternative options, sometimes with enhanced features or better value. OEMatch supplies non-OEM pollen/particle filters engineered as direct-fit alternatives to OEM parts, made to original-spec dimensions and tolerances for Porsche models.
Pollen and particle filters capture airborne contaminants drawn into the HVAC system, protecting occupants and preventing clogging of heater and air‑conditioning components. Filters are available in standard media, activated carbon and multi-layer constructions; selection depends on needs such as allergen removal or odour control. OEMatch lists more than 4,000 part numbers and over 8,700 OE cross-references aimed at supporting Porsche applications, with further items in development.
Available Types
- Standard particle filters for dust and pollen removal
- Activated carbon filters for odour and gas adsorption
- Multi-layer filters combining fine particulate capture and odour control
Benefits Include
- Cleaner cabin air and reduced allergen exposure for occupants
- Protection for HVAC components against dust buildup and blockage
- Improved climate control performance and consistent airflow
Why Pollen/Particle Filters Wear and Fail
- Gradual accumulation of dust, pollen and road debris leading to blockage
- Moisture ingress encouraging mould or bacterial growth in the filter media
- Saturation with soot and urban pollution reducing filtration capacity
- Physical damage or incorrect handling during servicing
The Importance of Replacing with OEMatch Pollen/Particle Filters
Timely replacement restores filtration performance and airflow, helping the HVAC system to work efficiently and preserving interior comfort in Porsche vehicles. Choosing the appropriate media—standard, activated carbon or multi-layer—addresses specific concerns such as allergens, odours or fine particulate pollution. Using correctly specified filters also reduces the likelihood of secondary issues caused by clogged units and supports routine maintenance intervals.
Advantages
- Options for basic particulate removal or enhanced odour control with activated carbon
- Media and dimensions selected to match Porsche model requirements for straightforward replacement
- Extensive part coverage with cross-references to help identify the right item for each model
