Do you know what we breathe?
Why is it important to know the level of air pollution?
Air pollution is caused by gases and particles emitted to the atmosphere by a variety of human activities, such as the inefficient combustion of fuels, agriculture, and farming. There are also natural sources contributing to air pollution, including particles of soil dust and salt in sea spray.

Air pollutants can be emitted directly from a source (i.e. primary pollutants) or can form from chemical reactions in the atmosphere (i.e. secondary pollutants). When concentrations of these substances reach critical levels in the air, they harm humans, animals, plants and ecosystems, reduce visibility and corrode materials, buildings and cultural heritage sites.

The main pollutants affecting human health are particulate matter, ground-level ozone (O3) and nitrogen dioxide (NO2). The fine particles that damage human health are known as PM2.5 (particles with a diameter of less than 2.5 micrometres), which can penetrate deep into the lungs and pass into the bloodstream affecting different organs and bodily functions. These particles are can either be emitted directly or formed in the atmosphere from several different emitted pollutants (e.g. ammonia (NH3), and volatile organic compounds (VOCs)).

Ozone (O₃), is an important secondary pollutant. It is a potent lung irritant and stunts growth in plants. It is also a powerful greenhouse gas (GHG). O₃ is formed in the troposphere, near the Earth's surface, when certain precursor pollutants react in the presence of sunlight. The powerful GHG, methane (CH₄), is responsible for a significant portion of O₃ formation. This tropospheric ozone is different from the ozone in the upper atmosphere (stratosphere), which protects us from ultraviolet light from the sun.

Nitrogen oxides (NOx) are a group of air polluting chemical compounds, comprising nitrogen dioxide (NO2) and nitrogen monoxide (NO). NO2 is the most harmful of these compounds and is generated from human-driven activities. It impacts human health, reduces atmospheric visibility, and can play a significant role in climate change, at high concentrations. Finally, it is a critical precursor to the formation of O₃.

How do I know the level of the pollution problem in my country/community?
Many cities have implemented monitoring networks that continuously measure air pollutants as part of their air quality management systems. Many of them regularly report an Air Quality Index (AQI) that is easy to interpret, and often color-coded, to warn of dangerous levels of air pollution. The information is accessible through websites, newspapers and apps. Countries define their own indices based on their own air quality standards. Therefore, they are not comparable between countries and are designed for public information purposes.

The availability of air quality monitoring is unequal globally and regionally. This is because high quality monitors are expensive, as is the cost of training people to run and maintain monitoring networks. Even in places with good monitoring, there are discrepancies. For example, in some parts of Europe, there are very dense monitoring networks, while in other parts the networks are less dense. In many developing countries across the world there is no official air pollution monitoring.

Investing in air quality monitoring is very important because the larger the networks are, the more information we can have for a city, a region or country. This information can be invaluable for helping people understand the air pollution levels where they live and take action to reduce their exposure. It's also important for governments, to be able to make short and long-term planning decisions to reduce air pollution.

In many places, private companies are developing lower-cost air quality monitors that people can install in their own homes. This is leading to networks of citizen scientists reporting on air quality and citizen led online air quality databases.

A number of international and civil society organizations, and private companies, also collect and report air quality information, often based on a combination of monitoring and satellite data. Where local information is unavailable, these can be useful resources to understand the air pollution problem in your city or country.
Is clean air a human right?
In at least 155 countries, a healthy environment is recognized as a constitutional right. Obligations related to clean air are implicit in a number of international human rights instruments, including the Universal Declaration of Human Rights and the International Covenant on Economic, Social and Cultural Rights.

In 2019, at the 40th session of the Human Rights Council, the right to breathe clean air was highlighted in a report by the Special Rapporteur for Human Rights and the Environment. The report highlights the seven steps that States must implement , to fulfil the right to breathe clean air.

What are the most harmful substances in the atmosphere?
The main air pollutants affecting health are fine particulate matter (PM2.5), ground-level ozone (O3) and nitrogen dioxide (NO₂).
Fine particulate matter of carbon, nitrogen, sulfur, heavy metals, etc. penetrate deep into the lungs and circulatory system. They cause damage to organs and tissues mechanically and toxically.
Ground-level ozone (O3) is produced in the atmosphere. Its aggressive effects affect the lungs, irritating them and causing discomfort when breathing.
Nitrogen dioxide (NO₂) also has a harmful effect on the lungs, and its high concentration causes secondary pollution.
The pollution level is measured in units of PM2.5. This means the presence of particulate matter smaller than 2.5 mm in diameter in the air - they are the most dangerous to health. Clean air has a value of PM2.5 = 0. A normal city gets 40-60 PM2.5. Values over 100 are already dangerous to health, and over 200 cause serious consequences. According to meteorological services, in megacities, PM2.5 values can reach 600.
Why is there not enough publicly available data on air quality?
In most large cities, pollution levels are measured with specialized stations. But such measurement does not always provide up-to-date data. Monitoring stations work only within 1-3 km and upload information within a few hours or a day. Their limited number is not able to cover all areas of the city, so the data on pollution is very inaccurate. And also after a few hours, the information may already be outdated.
At the moment there is no unified database where all the information about the state of the air is uploaded. Therefore, it is very difficult to track the level of pollution at the regional and global level.
1 out of 8 deaths in the world is due to poor air quality
This is one of the largest public health threats of our time
Air pollution poses a major health risk, while people are unaware of to what extent the air they breathe is bad. The limited number of costly measuring stations does not allow for a thorough examination of air pollution.

Small, smart devices that sit outside your window and detect air quality by networking together to be as efficient as possible. Every time someone connects this device to their wifi - it extends the global air monitoring network.

Unlike reference sensors, the new digital sensors are smaller, more compact, much cheaper, easier to use and provide high-resolution spatiotemporal concentrations of air pollutants. They pick up odorless, invisible particles that are very harmful to our bodies.
Every major city contains hundreds of harmful substances that we breathe.
But in order to detect air pollution and warn you about it in time, you only need to identify one substance contained in almost all urban emissions - PM2.5
According to the World Health Organization (WHO), the average daily level of PM2.5 should not exceed 25 µg/m3 and the average annual level is 10 µg/m3.

Fine particulate matter is the most dangerous form of air pollution. They instantly penetrate the lungs, circulatory system and other important organs, accumulating there and causing health problems.

Nebo Air can quickly and accurately detect the concentration of PM2.5 in the atmosphere. The more Nebo Air sensors installed in one area, the more accurately they can detect regional levels of pollution.

So by installing Nebo Air, you are not only taking care of your health and that of your family, you are also contributing to global pollution monitoring.
How it works
The device sends a focused laser beam into the air and uses a fan to direct the airflow into the beam. Microparticles in the air cause scattering of the laser beam - the degree of scattering is registered by a photodiode.

The microprocessor processes the LED data and converts it into a digital PM2.5 value. This value is displayed on the Nebo Air screen.
