Overview
Mercedes-Benz USA is the first automobile manufacturer to achieve asthma & allergy friendly® Certification for their cabin air filters. Rigorous testing conducted by Airmid Healthgroup demonstrated the filters’ effectiveness in removing airborne allergens such as Birch tree, Timothy grass, and Ragweed pollen, improving air quality for vehicle occupants and providing a healthier driving environment.
Background
About Mercedes-Benz USA:
Mercedes-Benz is a global leader in automotive innovation, known for its commitment to safety, luxury, and cutting-edge technology. With growing concerns about air quality, Mercedes-Benz USA sought to enhance the in-cabin experience by addressing the health needs of drivers and passengers, particularly those with asthma and allergies.
About Airmid Healthgroup:
Airmid Healthgroup is a world leader in health-focused testing, specializing in allergens, air quality, and consumer product validation. Their expertise supports manufacturers in achieving rigorous certification standards.
Context:
Air pollution, including exhaust fumes, particulates, and allergens like pollen, can accumulate in vehicle cabins, impacting air quality. With urban populations spending significant time in cars, cabin air filters play a critical role in improving in-cabin air quality, reducing exposure to pollutants, and creating a safer environment for sensitive individuals.
The Challenge
Mercedes-Benz sought to validate the efficacy of their cabin air filters in addressing:
- Allergen Removal: Effective filtration of airborne allergens such as Birch tree, Timothy grass, and Ragweed pollen.
- Particle Filtration: Removal of allergen-associated particles ranging from 3 µm to >10 µm.
- Material Integrity: Ensuring the filters met fiber shedding requirements to maintain performance over time.
Meeting these challenges was essential to earning asthma & allergy friendly® Certification and demonstrating their commitment to occupant health.
Goals
- Primary Goal: Achieve asthma & allergy friendly® Certification by meeting stringent criteria for allergen and particle removal.
- Secondary Goal: Enhance consumer trust by validating the filters’ health benefits through independent scientific testing.
Solution/Approach
Airmid Healthgroup conducted comprehensive testing of Mercedes-Benz cabin air filters using a modified ASHRAE 52.2 test rig to evaluate their performance against certification standards:
-
Allergen Removal Testing:
- Filters were tested for their ability to remove airborne allergens associated with Birch tree (Bet v 1), Timothy grass (Phl p 5), and Ragweed (Amb a 1) pollen.
- These allergens were chosen to represent different points in the pollen season: tree pollen in Spring, grass pollen in Summer, and weed pollen in Fall.
-
Particle Filtration Efficiency:
- The filters were assessed for their initial and final efficiency at removing particles ranging from 3 µm to >10 µm using allergen-containing test dust.
- Efficiency was measured after loading the filters with dust to simulate real-world conditions.
-
Fiber Shedding Test:
- Filters were subjected to a fiber shedding assessment to ensure compliance with standards and confirm material integrity under prolonged use.
Key Results
- Allergen Removal: Filters effectively removed Birch tree, Timothy grass, and Ragweed pollen allergens.
- Particle Filtration: High efficiency in removing allergen-associated particles ranging from 3 µm to >10 µm, even under dust-loaded conditions.
- Material Integrity: Filters passed the fiber shedding test, maintaining structural integrity and performance over time.
Impact
Industry Leadership: Mercedes-Benz is the first automobile manufacturer to achieve asthma & allergy friendly® Certification for cabin air filters, setting a new standard in vehicle air quality.
Enhanced Consumer Trust: Independent validation by Airmid Healthgroup provides consumers with confidence in the filters’ ability to improve in-cabin air quality.
Healthier Driving Experience: Certified cabin air filters contribute to a healthier and more comfortable environment for drivers and passengers, especially those with asthma and allergies.
Lessons Learned
- Comprehensive Testing Drives Innovation: Rigorous allergen and particle testing ensures products meet the highest health standards.
- Vehicle Air Quality Matters: Cabin air filters play a critical role in mitigating exposure to allergens and pollutants in confined spaces.
- Independent Validation Builds Trust: Certification by respected third-party organizations like Airmid and AAFA enhances credibility and market differentiation.
Conclusion
Mercedes-Benz USA’s partnership with Airmid Healthgroup highlights the importance of scientifically validated health claims in consumer products. By achieving asthma & allergy friendly® Certification for their cabin air filters, Mercedes-Benz has set a new benchmark for in-cabin air quality, enhancing the health and comfort of vehicle occupants.
