What are we breathing in every day at home?

1. Air pollution and home air purification: How can we protect our health?

2. Did you know that 99.1% of the world's population lives in areas where the level of air pollution exceeds recommended values?

3. The effects of air pollution on our daily lives

4. According to the World Health Organization, one in three deaths caused by stroke, lung cancer, and heart disease is due to 5. polluted air 6. due to its negative effects, which are comparable to the harmful effects of tobacco smoke. Are there solutions to reduce the impact on people's health and improve the situation? 

7. Air pollution is one of today's biggest environmental challenges, significantly affecting people's health. Air pollution is not only a problem in large cities or industrial areas – the air in our own homes can also be filled with harmful substances that can lead to respiratory diseases in the long term. The 8. pollution of the air 9. contributes to respiratory disease, 10. the development of allergies and even increases the risk of cardiovascular diseases in the long term.

11. How clean is the “fresh” air?

12. When we open the windows to ventilate our homes or offices, we believe we will be breathing fresh and clean air. Fresh, yes, but is it also clean? Most people live in cities and towns where 13. air pollution 14. is constantly present. The 15. air pollution 16. allows pollutants from the outside to easily enter our homes, carrying dangers such as the 17. development or the 18. exacerbation. allergy its formation or the respiratory disease intensification.

Disheartening statistics

According to the United Nations, 15. air pollution it poses one of the greatest threats to human health. More than 90% of the world's population breathes air that exceeds acceptable pollution levels. Particularly dangerous are tiny pollutants, such as fine particles with an aerodynamic diameter of less than 2.5 microns (PM2.5), which penetrate deep into the airways and can contribute to various respiratory disease health issues.

Pollutants vary in size (between one micron and 0.1 mm) and origin. Studies have shown that fine particles with an aerodynamic diameter of less than 2.5 microns (PM2.5) cause the most significant harm to human health. When inhaled, these particles do not remain in the nose and nasopharynx but immediately enter the lower airways (bronchi, bronchioles, alveoli) and the cardiovascular system. Numerous viruses and bacteria can enter the human body with them. Due to their light weight, fine dust can remain suspended for a long time and is almost constantly present in the air.

The World Health Organization (WHO) has also published its own data on the issue: in 2019, 99% of the world's population lived in areas where air pollution levels exceeded the values set in WHO recommendations. According to the organization, the combined effects of outdoor and indoor air pollution contribute to the premature death of 6.7 million people each year. WHO estimates that in 2019, air pollution caused 4.2 million premature deaths worldwide. Consequently, polluted indoor air was responsible for approximately 2.5 million premature deaths. And this is just data for one year.

Children are at the greatest risk

Children are particularly sensitive to air pollution and its effects. Scientific data indicate that frequent exposure to polluted air at an early age leads to long-term health consequences, such as respiratory diseases, lung and cardiovascular diseases, lung cancer, neurological and neurodegenerative diseases, diabetes, and other illnesses. Respiratory diseases associated with air pollution include common childhood illnesses such as upper respiratory infections, otitis media, and allergic diseases.

Due to their physical characteristics, children are more sensitive to the effects of air pollution than adults, as they breathe twice as fast and often through their mouths, inhaling a larger amount of pollutants. Moreover, their respiratory organs are closer to the ground, where the concentration of pollutants is highest. Children are physiologically more sensitive to air pollution than adults because their brains, lungs, and other organs have not yet fully developed, so their defense mechanisms against toxic pollutants do not function as well as those of adults. Long-term exposure to pollutants can disrupt the growth and development of their organs and affect brain development during the crucial early years of life, leading to long-term consequences for physical and mental development.

Sources of pollution

The environmental and indoor air pollutants are a complex mixture that includes particulate matter, ozone, nitrogen dioxide, carbon monoxide, and sulfur dioxide. It may also contain benzene or heavy metals such as arsenic, chromium, lead, and mercury. The most common sources of air pollution are the burning of fossil fuels (e.g., coal), as well as waste and garbage, industrial production processes, agricultural activities, construction, demolition, vehicles, etc.

The level of indoor air pollution directly depends on the air parameters and the presence of various pollution sources within the indoor spaces – in houses, apartments, kindergartens, schools, healthcare facilities, etc. The quality of indoor air typically deteriorates due to smoking, the use of household chemicals and personal care products, cooking, heating with coal and biofuels, etc. It should be noted that solid fine particulate matter from combustion processes is one of the most harmful forms of air pollution. They are colorless and odorless and can penetrate deeply into the lungs, bloodstream, and brain, causing health problems.

Since air pollution has both outdoor and indoor sources, maintaining proper air cleanliness must meet two ultimate requirements: the continuous removal of polluted exhaust air from the rooms must be ensured, and a constant flow of external supply air must be provided.

What can we do about it?

1. Although a comprehensive solution to the problem of air purification requires the cooperation of the entire international community, we can take care of the cleanliness of indoor air locally on our own.

2. Ventilation plays a key role in this. Modern ventilation systems not only continuously draw out polluted air but also clean the fresh supply air entering the room. For this purpose, coarse and fine filters are used, which can be installed in the ventilation systems.

3. Coarse filters (G1-G4 filtration class) capture the largest pollutants: large synthetic particles larger than 0.4 microns at 60-90%. These filters form a primary barrier to prevent the penetration of large pollutants (insects, feathers, fluff, animal hair, large seeds, dust, soot, etc.) into the ventilation system and the room. Coarse filters have a simple design and can be made from thin sponge, metal mesh, or synthetic fabric.

4. Fine filters (F5-F9 filtration class) can retain particles smaller than 0.4 microns at up to 75%. Due to the high density of the filter medium, they retain the most dangerous particles to human health – medium and fine dust, pollen, mold and mildew spores, as well as bacteria. The design of most fine filters is not much different from that of G class filters, but they are made from denser material, which is most often synthetic fabric.

5. The advantage of ventilation systems equipped with air filters is that the filters can be easily removed and replaced. Any filter can be purchased separately and installed independently in both existing air handling units and in ventilation systems placed in a single room (heat exchanger), by selecting the desired filtration class. In addition, there are separate filter units (filter boxes) that are placed in supply ventilation systems. Such filter boxes can have not only coarse and fine filters but also so-called HEPA filters, which provide ultra-fine air purification (with a minimum efficiency of 99.97% for particles of 0.3 microns in size).

6. Household exhaust fans installed in bathrooms also contribute to the rapid removal of pollutants caused by household chemicals such as detergents, cleaning agents, etc.

7. Thus, ventilation systems not only ensure continuous air exchange and the supply of fresh air, creating a comfortable microclimate in the rooms, but also maintain a high degree of air cleanliness for adults and children to breathe.
