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 higher than
that of bicyclists, pedestrians and public transfer riders.
Increased exposure to these pollutants can produce serious
health problems. Benzene is a known carcinogen and VOCs are also likely
cancer agents. Almost all the pollutants can irritate the eyes, nose, and
respiratory systems of people 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 conditions like asthma. Car air filters purify the air inside
a car, allowing the passengers to have healthy and clean air to breathe.
Car air filters come in two main types: the panel style, as
used on most 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 the engine.
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 rule of thumb is to change filters once or twice a year, or roughly once
every 15,000 miles. Replacing a clogged air filter has two-fold impact on the
engine: a fuel economy benefit: up to 10%, which makes for equivalent gasoline
savings up to 15¢ per gallon.
Dirty and dusty driving conditions will require more frequent filter replacements. It is important to avoid using the wrong size filter in a car.

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