The Important Function of Car Air Filters

Studies conducted over the past two decades demonstrate that the exposure of the passengers inside a car to the dangerous air pollutants including respiratory irritants, neurological agents, volatile organic compounds (VOCs), carbon monoxide and carcinogens is significantly greater than that of bicyclists, pedestrians and people transfer riders.

Increased exposure to these pollutants can create severe health issues. Benzene is a known carcinogen and VOCs are also likely cancer agents. Almost all pollutants can irritate the eyes, nose, and respiratory systems of individuals exposed to them.

They also may hinder the development of fetuses and infants. Studies indicate that the elevated levels of auto exhausts can also suppress the immune system, making human beings more vulnerable to colds, influenza, and other respiratory ailments like asthma. Car air filters purify the air in a car, allowing the passengers to have healthy and clean air to breathe.

Car air filters come in two main forms: the panel design, as used on many fuel-injected cars, and the radial style, which are usually used on carbureted vehicles. A car air filter is enclosed in a black plastic casing near the center-top of this motor.

The air filter traps dirt particles, which can cause damage to engine cylinders, walls, pistons and piston rings. Changing car's filters on a regular basis can have a significant impact on engine life and performance. A good guideline would be to change filters once or twice a year, or about once every 15,000 miles. Replacing a clogged air filter has exerts impact on the motor: a fuel economy benefit: up to 10 percent, which makes for equivalent gasoline savings up to 15cents per gallon. Dirty and dusty driving conditions will require more frequent filter replacements. It's important to avoid using the incorrect size filter in a car.

Nowadays, car owners are using 'Nanotechnology' based filters to improve cabin air quality. Such filters contain charcoal layers, which eliminate odors. These filters allow'mechanical filtration', where the fiber material of the filter with pores of a particular size will trap particles larger than the size of these pores. Almost 80 percent of the cars sold in U.S. include a built-in nanotechnology-based filter.
