DENSO PARTICLE FILTER: 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. OE QUALITY: As the world’s number one OE developer of heating, ventilation and air conditioning (HVAC) systems, you can be sure that DENSO’s air cabin products are manufactured to the highest standard. INNOVATIVE TECHNOLOGY: The fleece material is compliant with DENSO’s strict requirements, with a super-fine filtration of up to five layers. This means our filters can remove particles that are more than 100 times smaller than diesel soot. HVAC COMPATIBLE: Our cabin air filters are designed to work without causing a drop in air pressure. This protects the vehicle’s HVAC system, ensures superior efficiency and protects from condensation. DENSO ASSURANCE: Pollutants, smells and irritants can not only distract motorists, they can also become a health hazard if they are not dealt with correctly. DENSO Cabin air filters ensure that no harmful substances from the road enter the vehicle cabin, with two options available to purchase: standard particle filters and combination activated carbon filters.
