In recent decades, air conditioners have been widely used, with the main purpose of making the environment in which we live and work more comfortable, mainly in terms of temperature and humidity. This function is vital for some vulnerable populations, such as the elderly, patients with cardiovascular and mainly respiratory problems.
Indoor air pollution – which the Ministry of Environment defines as the presence in the indoor air of natural, chemical and biological contaminants, which are not normally present in the outside air – is an increasingly acute problem.
Indoor air depends on the air quality of the outside environment, to which are added the further pollutants that exist inside the buildings. Indoor pollution data, ie indoor air pollution, confirm that indoor air quality is 2 to 3 times worse than outdoor air quality.
Insufficient ventilation in closed buildings or rooms can damage the nasal epithelium and consequently make it difficult to breathe.
It has also been shown that excessive use of air conditioners can greatly damage the normal nasal breathing filter mechanism.
Inside the airways domestic allergens and germs can be found. When not cleaned effectively, especially those in public areas are the number one culprit for transmitting most influenza viruses, including H1N1. According to experts, they accumulate pathogenic microorganisms from the breath and sweat and diffuse them into the atmosphere, “recycling” them.
