What is Clean Air?
Clean air is air that has no harmful levels of pollutants
(dirt, dust, airborne microbes, and chemicals) in it.
Clean air is essential to good health and a basic
What is Particulate matter(PM)?
Particulate matter(PM) is the term for a mixture of solid
particles and liquid droplets found in the air. Some
particles, such as dust, dirt, soot, or smoke, are large or
dark enough to be seen with the naked eye. Others are so
small they can only be detected using an electron
microscope. PM10 means particles of diameter 10
microns (0.01mm), PM2.5 means particles of
diameter 2.5 microns (0.0025mm), PM0.1 means
particles of diameter 0.1 microns (0.0001mm).
What is the source of PM?
Some are emitted directly from a source, such as
construction sites, unpaved roads, fields, smokestacks or
fires. Most particles form in the atmosphere as a result of
complex reactions of chemicals such as sulfur dioxide and
nitrogen oxides, which are pollutants emitted from power
plants, industries and automobiles.
What are the Harmful Effects of PM?
PM10 / PM2.5 / PM0.1 can be
inhaled into the lungs. From there they can enter into the
Exposure to such particles can affect both your lungs and
your heart. Numerous scientific studies have linked particle
pollution exposure to a variety of problems, including:
premature death in people with heart or lung disease
nonfatal heart attacks
decreased lung function
increased respiratory symptoms, such as irritation of
the airways, coughing or difficulty breathing.
People with heart or lung diseases, children, and older
adults are the most likely to be affected by particle
PM0.1 is made up things that are more toxic (like
heavy metals and cancer causing organic compounds).
What are acceptable PM levels?
According to the WHO air quality guidelines for PM10
is 20µg/m3 as an annual average, but the data
released today shows that average PM10 in some cities has
reached up to 300 µg/m3.
eg. if you spend 1 hour in polluted air of
PM10 300µg/m3 then the rest 23 hours
you should spend in air having PM10 of just 8µg/m3
to reach the daily average of 20µg/m3
What is the quality of air where you live?
Can I monitor the Air quality in my home?
Yes, you can. A portable air quality monitor can accurately
tell you the condition of air around you.
What can be done to improve the air I breathe?
We breathe 20,000 liters of air everyday. 24x7. We cannot
control the quality of air we breathe outdoors but can
definitely control the quality of air we breathe when we are
at home, in our car or at work.
