From dust to hexavalent chromium (a chemical sometimes found in dyes, paints and plastics), natural latex to pollen, almost any material or substance can be a potential allergen. Ford testers make sure dyes and formaldehyde are strictly limited to levels that are acceptable even for clothing.Cleanest possible cabin airCabin air filters improve driving comfort by reducing particle concentration, improve cleanliness and protect climate control components from particle deposits. These filters also capture soot, smog and tobacco smoke. Because of the seamless way it works, many customers may not realize they have a cabin air filter. In most cases, the filter is accessed through the glove box. Ford dealers change the filters as part of the recommended maintenance for all vehicles. Health and wellness researchIn 2011 Ford kicked off a series of research projects for in-car health and wellness-connected services such as medical device connectivity, cloud-based health management services and mobile app integration. In just more than a year, Ford delivered on the initial research with launch of the SYNC AppLink-compatible Allergy Alert app – available on the 2013 Fusion and other new Ford vehicles – and as one of the first steps toward helping drivers take care of themselves and their passengers. With SYNC ® AppLink ™, drivers can quickly access allergy information through the Allergy Alert app. Through the app's pollen index rating, drivers can request to hear the types of allergen conditions they are likely to encounter that may cause a flare-up in personal allergy symptoms. The app also provides a risk index for asthma, flu/cough/cold and ultraviolet rays. Drivers can access Allergy Alert app information simply by connecting smartphones or tablets to their cars using simple voice commands, while keeping their hands on the wheel and eyes on the road.
