How cabin air filters work

Pollutants, smells and irritants can not only distract motorists, they can also become a health hazard if they are not dealt with correctly. Cabin air filters ensure that no harmful substances from the road enter the vehicle cabin, with two options available to purchase: particle filters and combination filters.

DENSO’s particle filters have a multi-layer fleece material that removes dust and solid matter from the air. With a large dust-holding capacity and minimal air flow resistance, they offer exceptional protection from dust, soot, pollen and particles. Our range of combination filters purify the air in a range of ways. First, they capture particles in a close meshed, non-woven filter layer. Then, any small charged particles are held back by electrostatic interaction. Finally, a layer of nanofibers is spun into the filter media, preventing the air pressure from dropping.

This superior technology means you can be sure that a DENSO air filter provides a safe, relaxing in-cabin experience kilometer after kilometer.

Cabin air filters types

Particle filters

With five individual layers that trap pollutants and particles as small as 0.01 micrometers, our non-woven fleece material ensures superior performance and protection.

Combination filters

With an added layer of carbon and a filter that is sealed to the housing, almost 100% of pollutants, particles and odors are captured in DENSO’s combination filters.

Characteristics

Our non-woven fleece material has five distinct layers that capture and remove potentially harmful pollutants and particles journey after journey.

Installation and fault finding

Installing a cabin air filter correctly and ensuring any faults are fixed quickly will help maintain a safe and relaxing driving experience for customers.

Installation

Find out more about how to install cabin air filters.

Following the car maker’s fitting instructions, locate the filter. Remove the filter, taking care not to knock any particles from the old filter into the cabin.
Insert the new cabin air filter into the designated filter box.

Fault finding

Cabin air filters can be kept in good condition with regular checks and replacements where necessary.

If a cabin air filter becomes too full of dirt, particles and pollutants, then it can stop working as effectively and even affect the performance of the HVAC system.

If you start to notice strange smells, sneeze or get eye irritation in the cabin, then this could be a sign that the cabin air filter needs changing.
A drop in the performance in the car’s HVAC system can also be an indicator.

To keep cabin air fresh, clean and safe to breathe it’s important that Cabin Air Filters are changed every 10-15,000 km, once a year, or as specified by the vehicle manufacturer. This is because cabin air filters become less efficient as dust and dirt builds up over time. Dirty filters can even harbor mildews and bacteria, causing allergies and discomfort. Failure to change a dirty filter will greatly reduce the air quality inside the vehicle. It can even affect the performance of the car’s air conditioning system.
