The innovations of sophisticated industrialization processes, the search for comfort and the improvement of the quality of life of man; They have led to great inventions; but in turn they have also generated high rates of devastation and pollution, air pollution being one of the factors that most affected people’s activities and normal lives.

According to studies by the Environmental Protection Agency of the United States, indoor air is usually twice as polluted as that from outside, a fact that is worrying and we tend to observe too much pollution in the street; caused by dust, smoke from vehicles and industries, among other elements.

However, although a person does not observe these types of factors in their workplace, it does not mean that the indoor air is clean; since in this one they are contained countless microparticles and organisms imperceptible to the human eye, but the workers of an office, days coexist with them.

In addition to pollutants that can come directly from outside to inside an office; The ducts of the air conditioning system of the same usually play a fundamental role in the protection and proliferation of germs that in some cases can severely affect the health of the occupants.

In general, the person in charge of the maintenance of the building thinks that it is only enough to perform cleaning tasks to the air source, that is, to address the coil, the evaporator, the filter bank and the elements of the unit; but forgot about the ductwork.

Undoubtedly this is a serious error, since the air ducts (cold, hot or fresh) will be taken through the pipelines, as required and in the event that these transport systems are contaminated by pollen, fungi, bacteria, parasites and other harmful biocontaminants; All of these will be absorbed by the people who inhabit the property.

In the pipelines it is common to find remains of construction materials such as stones, nails, pieces of cloth, plastics, glass bottles, among others; which are mostly inert, do not directly affect, however, they do lead to the accumulation of dust and the spread of germs.

The accumulation of dust inside the ductwork is subsequently expelled through the grilles or diffusers, reaching the users of the building, who breathe this element, which can cause mild discomfort such as a sneeze or serious conditions that impact on the ability to concentrate entrusted activities; There are even cases in which death has occurred due to this cause.

Of the great variety of pollutants that accumulate and are transported through the pipelines, there is no doubt that organic is one of the most powerful against health; since there are frequent respiratory diseases whose duration is prolonged, severely afflicting all the inhabitants of this environment due to their ability to spread.

The most recurrent symptoms presented by the occupants of the property, whose indoor air quality is bad, are:

• Difficulty breathing
• Itching
• Headache
• Irritations of eyes, nose and throat
• Hoarseness
• Skin rash
• Increased incidence of respiratory infections and colds
• Mental fatigue
• Sequence sensation in mucous membranes and skin
• Nausea, dizziness and dizziness

When presenting these symptoms on a recurring basis, the first recommendation that the person suffering from should follow is to see a doctor, but it must be taken into account that many times when being examined, they do not present any type of condition. It can also happen that these symptoms are widespread among the inhabitants of a property, so it can be considered as a problem of the building.

Hence the importance of the aseptic measures of the place, but above all the cleaning and disinfection of the air conditioning ductwork.
