ClearAir+ Cabin Air Filter: Five Layers of Protection, Powered by A/C System Expertise

With decades of experience in thermal systems and A/C System technology, DENSO applies its OEM-level engineering standards to every aftermarket product. Cabin air filters are an integral part of the vehicle’s A/C  system, and DENSO ClearAir+ reflects its commitment to delivering optimal airflow, filtration efficiency, and comfort — the same principles trusted by leading vehicle manufacturers worldwide.

Five Layers. One Mission: Cleaner Air Inside Your Vehicle

DENSO ClearAir+ is not a standard cabin air filter — it’s a multi-stage defense system designed to address the full spectrum of contaminants found in modern driving conditions:

• Pre-Filter Layer 

Keeps your cabin air filter cleaner for longer! The silver chlorite technology actively prevents mold and fungi growth, ensuring lasting performance and a healthier environment inside your vehicle.

• Antimicrobial / Anti-Virus Protective Layer

Your first line of defense against harmful microbes. This advanced layer captures aerosol-borne bacteria and viruses, while its special impregnation stops bacteria from multiplying and eliminates enveloped viruses. Plus, negatively charged ions (anions) actively fight viruses, giving you peace of mind every time you drive.

• Activated Carbon Layer 

Breathe easier with premium activated carbon. It absorbs harmful gases like NOx, SOx, and ozone, while neutralizing unpleasant odors from traffic and fuel emissions, so every journey feels fresh and clean. 

• Anti-Allergen Layer 

Say goodbye to allergy discomfort! This layer binds or inactivates pollen proteins, reducing allergic reactions and improving comfort for sensitive passengers.

• Electrostatic Microfiber Layer 

Maximum protection against fine particles. Filters out pollutants as small as 1 µm, including PM10, PM2.5, PM1.0, pollen, and brake dust, helping protect your respiratory health and ensuring cleaner air for everyone on board.

Why Choose DENSO ClearAir+?

• Unique Health Protection: DENSO ClearAir+ goes beyond standard filtration with an activated carbon layer by offering multi-layer defense against viruses, bacteria, and allergens,  creating a cabin environment free from these harmful contaminants: removes over 99% of viruses and bacteria.
• ISO-Certified Performance: Independently tested and certified by external EU-accredited laboratories to meet international standards for air quality and filtration efficiency, in compliance with ISO 18184 and ISO 20743, delivering proven protection you can rely on.
• OEM Expertise: Developed using DENSO’s global engineering standards for A/C systems, delivering balanced filtration and airflow for real-world driving conditions.
• Comprehensive  Vehicle Cabin Safety: Protects the cabin air while maintaining optimal airflow for A/C System performance.

Why A/C System Integration Matters?

Cabin air filters are not standalone components — they are a critical part of the whole A/C system. That is why a proper integration ensures:

• Stable Airflow: Filters designed for A/C system specifications maintain correct pressure drop, preventing strain on blowers and ensuring consistent heating/cooling performance.
• Energy Efficiency: Optimized cabin air filter minimizes unnecessary load on the A/C system, helping improve fuel economy and overall performance.
• Comfort & Safety: Effective filtration combined with A/C system airflow management ensures clean, temperature-controlled air reaches all vehicle cabin zones.
