Product Information

Full details

The Denso ClearAir+ cabin filter (DCF806A) is designed for vehicle owners who prioritize interior air quality and HVAC system longevity. It offers a significant improvement over standard filters by utilizing 5-layer technology to block bacteria, viruses, allergens, and fine particulate matter. While it provides superior filtration and improved air purity, users should note that the high-density construction requires strictly following the recommended 15,000 km replacement interval to maintain optimal airflow.

FAQs

How often should I change the DCF806A filter?

It is recommended to replace the filter every 15,000 km or once every year, whichever comes first.

Can I vacuum this filter to make it last longer?

No, vacuuming or washing will destroy the electrostatic fibers and compromise the filtration efficiency.

Does this filter stop odors?

Yes, the multi-layer technology is designed to reduce harmful gases and odors from entering your cabin.

What is the primary benefit of the 5-layer design?

The 5-layer design allows for superior capture of both fine particulates and biological threats like viruses and bacteria.

Will this filter overload my A/C system?

No, the filter is engineered to maintain even airflow, which actually helps prevent A/C system overload and condensation.

Troubleshooting

Weak airflow from vents

Check if the filter was installed in the wrong direction or if it is clogged and overdue for replacement.

Musty smell when A/C turns on

Replace the filter immediately and consider using an A/C evaporator cleaner to remove mold buildup from the system.

Filter does not fit housing

Verify the MPN (DCF806A) matches your vehicle's specific make and model requirements as cabin air filter dimensions vary.

Pros and Cons

Pros

  • Removes up to 99% of bacteria and viruses
  • Effective at neutralizing unpleasant road odors
  • Reduces strain on the A/C blower motor
  • Captures fine debris like brake dust and soot
  • Reliable manufacturing backed by 75 years of automotive expertise

Cons

  • Requires annual or 15,000 km replacement
  • May restrict airflow more than budget paper filters if left in too long
  • Specific to select vehicle models (verify compatibility before purchase)

Setup, Compatibility & Care

Installation typically requires accessing the cabin air filter housing, which is most often located behind the glove box. Refer to your vehicle's owner manual for the specific removal procedure for your dashboard layout. When installing the DCF806A, observe the 'Air Flow' arrow printed on the side of the filter frame to ensure it is oriented correctly toward the blower motor. To maintain performance, replace the filter annually or every 15,000 km. Avoid attempting to clean or wash the filter; doing so will damage the electrostatic properties of the fibers and render the filtration ineffective. Ensure the housing seal is tight upon reinstallation to prevent air bypass.
