How actively dusting of ventilation systems occurs depends on their complexity and the type of object. The system becomes clogged the faster, the more it turns, bottlenecks, additional elements. Also, accelerated clogging of ventilation occurs with poor installation.
However, in addition to direct dust pollution also leads to the spread of bacteria. The activity of this process largely depends on the functional purpose of the serviced premises and is especially high for, for example, exhaust systems from sanitary facilities, kitchen premises, and local suction.
In any case, pollution of ventilation leads to a number of negative consequences.

Deterioration in performance and decrease in ventilation efficiency
Dust and dirt in the air ducts, as well as airborne equipment leads to a decrease in the efficiency of each element of the system, and the system as a whole.
In practice, this means underheating of the incoming air, its underworking, reduction of consumption, increase in energy consumption for the operation of the system. And these are only obvious factors that can be seen or measured.

Any contamination increases the risk of fire, and this is especially true for ventilation systems, since they contain both electric drives (fans) and directly heated surfaces (air heaters).

So, through constructive gaps the dust gets inside the fans and electric drives of the fans. As a result, the friction between moving parts increases, they are heated and overheated, the failure and the risk of fire occur.

At the same time, the dust on the surface of the stove plays the role of thermal insulation. At the same time, the air does not have time to warm up to the desired temperature, and the heater automatics increases its operating temperature, which ultimately also leads to overheating of the equipment, breakdowns and increased fire hazard of the system.

Dust and dirt in the ventilation system can be a source of infection.
However, there are also a number of unobvious factors that the functioning of polluted ventilation systems carries with it. Among them, for example, deterioration in the well-being of apartment owners or office employees, a decrease in their immunity, and an increased risk of diseases due to a sharp increase in the number of bacteria.

These factors are difficult to notice and impossible to measure. Since the process of clogging of ventilation systems is slow and stretched in time, the gradual deterioration in the quality of the air environment is imperceptible.

Ventilation ducts before and after cleaning
However, the effect of cleaning measures is always noticeable: literally in a couple of days, after the completion of cleaning, it turns out that there is more air and it has become cleaner and fresher. In fact, there is a feeling of moving to a new level of comfort, and this in turn has a positive effect on the general mood of the staff.
