Air purification is increasingly important nowadays. Taking into account urban pollution, caused mainly by fossil fuels, and ever more present in our daily lives, methods are needed to filter the air. In view of the harmful health consequences of this situation, it is then necessary to destroy pollutants and contaminating agents. In regard, PARTTEAM’s digital billboards indirectly also play an important role, in that they can function as air purifiers.
The WHO (World Health Organization) estimates that 50% of the world population suffers from harmful air quality. The same study points to the worsening of diseases in the cardiovascular system, eyes, skin and head. Keeping the air cleaner is therefore a necessity to protect and prevent some health problems.
Improving the quality of life and air can be facilitated with the appropriate use of technologies, specifically air purifiers, which in turn filter oxygen and return clean air to the environment. In addition, they degrade contaminating agents as well as sources that cause bad odors.
In this sense, PARTTEAM & OEMKIOSKS digital billboards also end up being part of this process, but in a simplified way. That is, despite not fully purifying the air, the kiosks have fans that absorb the air and others that expel it. When the air is absorbed, it passes through a filter that prevents dust from entering, for example. In a way, when the air is expelled, it comes out cleaner. This help from PARTTEAM & OEMKIOKS – which creates a healthier environment, improving air quality – promotes, once again, the movement of cleaner and, therefore, smarter cities.
Still regarding air purification, it should be noted that, just as there is a wide variety of pollutants in the air, there are also different filters that can partially retain these pollutants. The most common filters are made of cellulose or plastic fiber. However, some may consist of plastic foam.
The use of UV in air purification
Depending on the type of pollution, different methods of purification can be used. For example, if we are purifying in order to remove airborne bacteria, we need to ensure that the bacteria in the air becomes inactive. We don’t need to physically remove them. In this case, the air can pass through a channel where it is exposed to germicidal radiation for a sufficient period of time. A common form of germicidal radiation is ultraviolet radiation (UV). Ultraviolet light has been used for several years by health professionals in the cleaning of rooms and equipment, being recommended for its ability to destroy germs and other biological pollutants.
The demand for domestic air purifiers is growing substantially, which can be explained by concerns about air quality. Although the houses were designed as a “shelter”, they are increasingly used for teleworking – especially now considering the global health crisis we are facing due to the COVID19 pandemic. Therefore, even indoors, we are exposed to indoor pollutants that can induce or worsen lung diseases. Indeed, an air purifier can help remove the following particles: allergens, mold, smoke and toxins from cleaning products (for example). Purifying indoor air has thus become a priority, because cleaner air prevents the spread of viruses.
