Static Cotton Layer
Bosch adds an additional static-cotton layer to increase the filter’s particulate-holding capacity.
Together, these layers are designed to capture microscopic pollutants including:
- Pollen
- Mold particles
- Common allergens
- Fine airborne particulates
Structural Ribs Help Maintain Filter Shape
Filtration performance isn’t determined solely by the media.
The Bosch 6055C incorporates structural ribs designed to increase filter stability. These ribs help the filter maintain its shape and airflow characteristics while installed in the HVAC housing.
This construction can be particularly important as the filter accumulates contamination during normal use.
No Formulated Chemical Odor Neutralizer
Bosch specifically states that its HEPA cabin filters provide filtration without adding a formulated chemical odor neutralizer.
That distinction is important when comparing the 6055C against activated-carbon cabin filters.
The Bosch 6055C is primarily positioned around high-efficiency particulate filtration, rather than activated-carbon odor adsorption.
When Should the Bosch 6055C Be Replaced?
Bosch recommends replacing its cabin air filters at least:
Every 12 months or 12,000 miles
Vehicles operated in environments with high particulate concentrations may require more frequent filter changes.
Dusty roads, construction areas and other high-contamination environments can load cabin-filter media more quickly than normal highway driving.
A contaminated cabin filter can also restrict airflow through the HVAC system, making periodic inspection worthwhile even before the normal replacement interval.
For an example of the basic replacement process, Pro Street’s Honda Accord Cabin Filter Replacement Guide shows how a typical cabin filter is accessed and replaced.
Vehicle-Specific Fitment
The Bosch 6055C is a vehicle-specific filter, but the product information supplied here does not include its year/make/model application list.
Because of that, I would not publish a fitment table or claim compatibility with specific vehicles yet.
Bosch recommends verifying the vehicle’s:
Year + Make + Model + Trim
before purchasing.
This is especially important because a cabin filter that looks dimensionally similar may not correctly fit or seal inside a particular HVAC housing.

Frequently Asked Questions
Is the Bosch 6055C a HEPA cabin filter?
Yes. Bosch identifies the 6055C as a HEPA cabin air filter.
What filtration efficiency does Bosch specify?
The supplied specifications state 99.97% filtration efficiency at 0.3 microns.
Does the Bosch 6055C contain activated carbon?
Activated carbon isn’t specified in the supplied product information. Bosch specifically states that this filter doesn’t use a formulated chemical odor neutralizer.
What does the Bosch 6055C filter?
Bosch describes its HEPA cabin filters as designed to capture microscopic airborne pollutants, including pollen, mold and common allergens.
How often should the 6055C be replaced?
Bosch recommends at least every 12 months or 12,000 miles, with more frequent replacement in areas with high particulate levels.
What vehicles does Bosch 6055C fit?
The supplied product information doesn’t provide a year/make/model list. Exact vehicle compatibility should therefore be verified before adding fitment claims to the product page.
