Why do you require Air Monitors and their Solutions?
Air pollution is any chemical, physical, or biological factor that contaminates the interior or outdoor environment and alters the natural properties of the atmosphere. According to WHO report, 99% of the world’s population breathes air that exceeds its guideline limits i.e 9 out of 10 people breathe bad air quality. Annually, 8 million deaths are claimed due to air pollution, 3.8 million indoor & 4.2 million outdoor pollution.
There has been a significant increase in air pollution levels around the world as a result of the dramatic growth in the world population. As a result, people are at an increased risk of respiratory illnesses. So, day by day, the reason for possessing an Air Monitor and its solution becomes clearer. The air quality monitor from Prana Air gives you the power to know what pollutants are in the air around you and how much they are polluting it. As a result, you can continue on with the solutions to make the air you breathe indoors healthier and cleaner.
Air Quality Sensor
The Technology We Use
Prana Air – air pollution monitors are packed with durable air quality sensors that infuse modern and accredited technology to measure air pollutants. An air quality sensor is a device that measures the air quality inside and outside the buildings as it pertains to the inhabitants’ health and comfort. The sensors are an important part of air handling systems in both residential and commercial buildings.
|Air Sensor||Operating Principle|
|Particulate Matter |
|Type of sensor: Optical 90˚ Light Scattering |
The light that strikes the aperture of the mirror at 90° is reflected towards the sensor. The photodiode registers pulse for as long as the light is reflected. The electrical signal thus received is converted into a concentration of particulate matter.
|CO2||Type of sensor: Non-Dispersive Infrared Sensors (NDIR) |
When infrared (IR) radiation interacts with gas molecules, the gas molecules absorb the light at a particular wavelength, causing vibration of the gas molecules. The sensors detect the reduction in transmitted IR light which is proportionate to the gas concentration.
|TVOC||Type of sensor: Metal Oxide Sensors (MOS) |
When semiconductor particles are heated in air at a high temperature, oxygen is adsorbed on the particle surface by capturing free electrons. A depletion layer is formed which is dependent on the radius of the semiconductor. The depletion can extend up to the whole area of each particle.
|Toxic Gases |
(CO, O3, NOx, SOx,
H2S & C2H5OH)
|Type of sensor: Electrochemical Sensors |
These are amperometric fuel cells with two electrodes. When the toxic gas comes in contact with the working electrode, the gas will get oxidized on the working electrode through a chemical reaction with water molecules in the air.
Air Quality Management System
All living things require air to survive. It is the basic necessity that sustains life on this planet. Everybody has a right to breathe pure air. However, the population explosion and fast-paced urbanisation have worsened the air quality over the last few decades. This decline in the air quality has left people around the globe gasping for breath. Therefore, there is an emerging need for efficient air quality management practices.
An Air Quality Management System is a comprehensive scheme for abating air pollution. It includes the effective monitoring of the parameters that impact and steer the air quality of an environment (indoor or outdoor). Monitoring is instrumental in identifying the chief pollutants in that environment, and thus, in chalking out a precise and holistic management plan to combat air pollution. Hence, air quality monitoring becomes the prime factor that enables us to breathe fresh and pure air.
Common air pollutants that render the air surrounding us unbreathable are particulate matter (PM), nitrogen dioxide (NO2), sulfur dioxide (SO2), carbon monoxide (CO), and total volatile organic compounds (TVOCs). However, some parameters that drive indoor and outdoor air differ from each other due to the difference in the sources of the pollutants. Thus, the permissible limits for air pollutants are also different for indoor and outdoor environments. These standards may also vary or can be relaxed depending on factors, such as country, availability of sources, etc.
Prana Air Outdoor Air Quality Monitor is Continuous Ambient Air Quality Monitoring System (CAAQMS) which works digitally and gives real-time air data. The monitor is installed with different sensors to detect the presence of PM 10 and PM 2.5, SO2. NO2, O3, H2S, and CO. It is low cost, easy to use, portable consumes very less time for analysis and has GSM, Wi-Fi, and RS-485 connectivity type. There are no after-purchase expenses and have GSM, Wi-Fi, and RS-485 connectivity type.
Air Quality Standards
Despite the fact that the recommendations are neither standards nor legally enforceable criteria, they are intended to provide direction for decreasing the health effects of air pollution based on the expert appraisal of current scientific information. These recommendations integrate scientific information from a variety of nations, making them applicable to a wide range of global situations and capable of supporting a wide range of air quality management policy alternatives.

Types of Air Quality Monitoring
Ambient Air Quality Monitoring
Outdoor Air is also called ambient air. Ambient Air Monitoring is one of the main aspects that determine environmental stability. Air pollution does not only harm us, but it is also detrimental to the ecology and the atmospheric chemistry of the earth. Meteorological factors also alter and impact air quality. Thus, outdoor air monitoring is essential.
Sources of Ambient Air Pollution
A blend of natural and anthropogenic (human-induced) sources are responsible for releasing harmful air toxins. Natural sources include forest fires, volcanic eruptions, earthquakes, sea spray, landslides, weathering of soil, pollination, wind storms, etc., and release considerable concentrations of air pollutants. Typical anthropogenic sources of air pollution are the emissions from various modes of transport, construction, and demolition, burning of waste, agricultural activities, oil and gas production, exhaust from chimneys, industrial activities, etc. Human activities also exacerbate some of the naturally-caused emissions.
- PM !
PM is the abbreviation for particulate matter (also called particulates). It includes a mixture of solid particles and liquid droplets found in the air, or simply aerosols. They vary in size. Some particles, such as dirt, smoke, fly ash, mists, condensing vapors, mist, soot, or dust, are conspicuous enough to be visible to the naked eye. Others are so tiny that they can only be detected with the help of an electron microscope things into perspective, PM2.5 is almost 1/30th of the size of a human hair! These include dust, dirt, and smoke.
These particles originate from both natural and anthropogenic (human) activity.
– Primary: Industrial processes, combustion, agricultural activities, construction and demolition, unpaved roads, windblown dust, smokestacks, and forest fires.
– Secondary: Other air pollutants, like NOx, SOx, and VOCs, that act as precursors for the formation of PM in the atmosphere.
- CO2 !
Carbon Dioxide CO2 occurs naturally from the atmosphere. It’s an essential ingredient in photosynthesis, the method by which plants produce food and energy. Degrees of carbon dioxide have grown since the Industrial Revolution.
– The principal causes are deforestation and the burning of all fossil fuels such as coal.
– Decomposition, ocean release, and respiration are the natural sources
Nitrogen Dioxide NO2 is traceable in the ambient air in the form of seven oxides. It is formed upon the oxidation of nitric oxide in the atmosphere. In its liquid form, nitrogen dioxide is colorless to brown.
Sources: Combustion sources are mostly responsible for the release of nitrogen dioxide. Vehicular emissions are its principal outdoor source. Power plants, industrial boilers, and diesel-powered heavy construction equipment are some other sources of this gas.
– Natural sources include volcanoes and bacteria.
Sulphur Dioxide (SO2) is a colorless, soluble gas with a characteristic pungent smell. It is highly reactive in nature and can react with other pollutants in the air to form fine particulate matter.
Sources: This gas is produced mainly from the combustion of sulfur-containing fossil fuels, such as coal and oil (eg, coal being burnt in a home fireplace for heating and diesel-powered vehicles). The chief sources of sulfur dioxide are industrial boilers, power plants, and other industrial processes like metal processing (Aluminium smelting and manufacturing of steel) and petroleum refining. Diesel engines are another key source, including old buses and trucks, locomotives, ships, and off-road diesel equipment.
– Natural sources include geothermal activity.
- O3 !
Ozone (O3) is a form of oxygen. Three atoms of oxygen bind together to form gaseous ozone. Ozone is considered a pollutant when its concentration in the lower atmosphere (troposphere) increases beyond the stipulated limit. Direct exposure to living with ground-level ozone (GLO) is very harmful.
– There is no source on the surface of the Earth that directly emits ozone, which means that it does not occur naturally. It is formed as the result of a photochemical reaction between oxides of nitrogen and volatile organic compounds (VOCs). The pollutants emitted by vehicles, power plants, industrial boilers and precipitators, refineries, chemical industries, and others react in the presence of sunlight to form ozone in the atmosphere.
Carbon monoxide (CO) — a colorless, odorless, tasteless, and toxic air pollutant—is produced in the incomplete combustion of carbon-containing fuels, such as gasoline, natural gas, oil, coal, and wood.
– Water heaters
– Furnaces or boilers
– Fireplaces, both gas and wood-burning
– Stoves (Wood and gas-based) and ovens
– Tobacco smoke
Indoor Air Quality Monitoring
We typically spend almost 90% of our day indoors, whether at our home, office, gym, or other indoor set-ups. We assume we are the safest in our homes.
The indoor air quality can be more toxic as compared to ambient air quality. The concentrations of a few air pollutants can be 2 to 5 times higher than their typical outdoor levels. What’s dreadful is that indoor air pollution influences the overall well-being of the people living in that environment. Having substandard indoor air quality compromises the health of the occupants of a building, putting you and your loved ones in jeopardy. Indoor Air Quality is both a comfort and a health parameter. Thus, monitoring becomes a necessity.
Sources of Indoor Air Pollution
The indoor sources of pollution mostly include the combustion of fuel-based materials and the use of household chemicals. Activities like cooking, burning of candles and incense sticks, painting, dusting, use of deodorants, etc. affect the indoor air quality. However, due to constricted space and clutter, the pollutants stay trapped in the indoor environment. This entrapment creates the pertinent problem of indoor air pollution.
- PM !
Particulate Matter (PM) is the suspended microscopic aerosol (solid or liquid) particles present in the air. PM 10 and PM2.5 are smaller than 10 micrometers and 2.5 micrometers in diameter respectively, out of which PM2.5 is respirable. To put things into perspective, PM 2.5 is almost 1/30th of the size of a human hair! These include dust, dirt, and smoke.
– Infiltration via doors, windows & walls (fenestration).
– Activities like cooking, combustion, and cigarette smoking.
- CO2 !
Carbon Dioxide CO2 is a colorless gas with a density about 53% higher than that of dry air. Its molecules consist of a carbon atom covalently double bonded to two oxygen atoms.
– Anthropogenic sources: production of cement, deforestation, fossil fuel, coal, oil, and natural gas burning
– Natural sources: ocean release, decomposition, respiration
- HCHO !
Formaldehyde is a naturally occurring organic compound with the formula CH₂O. The pure compound is a pungent-smelling colorless gas that polymerizes spontaneously into paraformaldehyde, hence it is stored as an aqueous solution.
– Sources of formaldehyde in the home include building materials, smoking, household products, and the use of un-vented, fuel-burning appliances, like gas stoves or kerosene space heaters.
- TVOC !
We use a lot of chemicals that vaporize upon exposure to air. Such compounds are called volatile compounds.
– Released through everyday household products like vinegar, nail polish, varnish, deodorants, etc.
– Substances like Benzene, Ethanol, etc. can be found in paints, cleaners, detergents, sanitizers, kerosene, petrol, and polishes.
- O3 !
Ozone is nothing but a form of oxygen. Three atoms of oxygen bind together to form gaseous ozone. On the ground, it is formed as the result of a photochemical reaction between oxides of nitrogen and volatile organic compounds (VOCs).
– Activities like cooking, combustion, and cigarette smoking.
- CO !
Vehicular emissions from cars, trucks, etc. are the greatest sources of CO. In the household, several items such as unvented kerosene, heaters, blocked and leaking chimneys, fireplaces/furnaces, etc impacts indoor air quality.
– Gas stoves, kerosene, furnace leakage, car exhaust, space heaters
