People who travel to work using their own cars or public transportation are exposed to a significant amount of air pollution during their commuting routine. The primary source of this pollution is the emissions from vehicles in proximity. In passenger vehicles, the air intake filters typically have low efficiency, allowing air pollutants to enter through open windows, gaps in door and window seals, and other openings. It has been observed that the concentration of air pollutants inside vehicles is greatly influenced by the operating conditions of the vehicle.

Hundreds of various materials, such as plastics, fibres, adhesives, paints, and lubricants, are used in the assembly of cars. And most of these materials disperse volatile organic compounds (VOCs) in the air inside cars. These VOCs include irritating chemicals and well-known carcinogens like benzene and formaldehyde. While the highest levels of off-gassing occur when the vehicle is new, commonly known as the “new car smell,” this release of compounds continues for several years and becomes most apparent on hot days.

Can Air Pollutants and VOCs Cause the Symptoms of COPD?

Chronic obstructive pulmonary disease (COPD) is exacerbated and its progression accelerated by lung damage. The presence of minuscule particles known as “irritants” in polluted air is responsible for damaging the lungs.

Regular exposure to air pollution increases the likelihood of developing COPD. When combined with smoking, the risk of COPD is further heightened.

Most vehicles currently on the road are equipped with a cabin air filter that serves the purpose of safeguarding occupants from harmful pollutants. This cabin air filter is distinct from the engine air filter commonly found under the vehicle’s hood and is a component of the ventilation system. Like air filters used in home HVAC systems, cabin air filters require periodic replacement to maintain their effectiveness.

If you detect a musty odor or experience reduced air circulation when you activate the air conditioner, it could be an indication that your filter needs to be replaced. Experts recommend using more efficient car air purification system like PetriMed CA APS 20 to reduce your exposure to traffic-related emissions and in-cabin air pollutants.
