FAQs

Is this filter compatible with my 2014 BMW 320i?

Yes, the LAO 812 is designed to fit F30/F31/F34 models produced from 2012 onwards.

Does this filter remove pollen?

Yes, the anti-allergic layer is specifically designed to trap pollen and other fine airborne allergens.

How often should I change this cabin filter?

We recommend replacing it every 15,000 miles or at least once a year for optimal health benefits.

Are there any cross-references for this part?

Yes, it is compatible with BOSCH 0986628543, CORTECO 64119237555, and FRAM CFP.

Can I wash the filter to make it last longer?

No, washing the filter will destroy the active carbon and antibacterial chemical layers.

What if the filter arrives damaged?

This product comes with a 60-day return policy; please contact the seller for a replacement if the unit shows any signs of defects.

Troubleshooting

Reduced airflow from the vents

The filter may be improperly seated or clogged with debris; remove the filter, check for blockages in the intake housing, and re-install.

Odors persist after installation

Ensure the filter is oriented correctly according to the airflow arrow indicator; if the issue continues, the HVAC system ducts may require professional cleaning.

Pros and Cons

Pros

  • Significantly higher air quality compared to standard cabin filters
  • Effective at neutralizing odors from traffic and external pollutants
  • Meets or exceeds original equipment manufacturer quality
  • Compatible with a wide range of F30, F31, and F34 BMW models
  • Durable construction ensures consistent performance over the service interval

Setup, Compatibility & Care

This filter is designed specifically for BMW 320 models (F30, F31, and F34 series) produced from 2012 onwards. Installation typically involves accessing the filter housing located under the passenger side dashboard. Always ensure the vehicle is parked on level ground and the ignition is off during replacement. To maintain maximum performance, replace the filter every 15,000 miles or annually, whichever comes first. Avoid washing or using compressed air to clean the filter, as this damages the active carbon and anti-allergic layers, rendering the specialized protection ineffective.
