Summer is approaching and many people wonder if it will be dangerous to use air conditioning in the car, at home, at work, indoors and if the mask could protect them from possible plant-borne coronavirus infection. air conditioning.
The principle of not transmitting the disease is the very good ventilation of the spaces, says Professor Virgil Musta, doctor of infectious diseases in Timișoara. Only if these spaces are ventilated with air conditioning systems that do not meet the conditions to have a filter with a bactericidal effect or if this filter is not changed according to the recommendations, then yes, they can be a source of contamination, said Dr Virgil Musta, Tuesday night, on Digi24.
In the case of air conditioning in the car, it can weaken the immunity of the body. It is those theories in Indian and Chinese medicine that the wind weakens the body. Therefore, people who remain in air conditioning, some of them, catch a cold very easily after these exposures, Professor Musta explained.
In the rooms, it is recommended that they be well ventilated, not necessarily with air conditioning, which, if you do not have the appropriate security filters, could be a source of contamination. There are special filters for air conditioning, which are made to sterilize the air, but they are very expensive and not all air conditioning equipment has these filters, says the doctor.
It also depends on what type of space we are talking about, if they are habitable spaces, where practically only the people in that house can contaminate the air, or common spaces, offices, where it is not known if they are sick people who carry the virus and can contaminate the air. If these facilities do not have special filters, they are a source of contamination. In such spaces, whether or not air conditioning is used, it is important to wear a mask and maintain that 2m distance.
The question is whether the air conditioning is good to work or whether it is not better to ventilate the rooms. Because good ventilation and natural ventilation in these rooms may be better than an air conditioning installation that does not meet clean air conditions, says Dr. Musta.
How good are sterilization lamps?
There are, on the other hand, lamps with a bactericidal effect. Even hospitals use this equipment that sterilizes and cleans the air or surfaces. It’s just that those in the hospitals are professionals, and the hospitals are documented beforehand before buying them.
In the case of people, there is a risk of buying products that do not really meet the specifications and the person has the impression that they are protected, but in reality they do not have this protection, explained Dr. Virgil Musta. Here, state control institutions would play an important role, which would not allow the exchange of anything. Verified and known things should be marketed, says the teacher.
There are lamps that act by ionizing the air, others by ozonating it, there are also ultraviolet lamps, but here there is also a problem, because it cannot stay in the room while they work: there is a risk of burning the skin or it can damage the skin. the level of the eyeballs and that is why they are used only when there are no people in that perimeter, warned Professor Virgil Nasta.
