Proper ventilation in a house or apartment allows for air exchange. Thanks to this, healthy conditions prevail in the rooms. Properly selected ventilation also allows for cleaning the air of various microorganisms. Today we will tell you how to properly take care of ventilation.

What types of ventilation are there?
Good ventilation allows the air inside the building to be exchanged with fresh air from outside. This solution ensures that the house does not accumulate moisture or form mold. Ventilation it also cleans the air from carbon dioxide, particles or dust, as well as mites or fine dust. In addition to all this, it removes unpleasant odors. We can distinguish three types of ventilation such as:
- gravity (also known as natural) - its method of operation is very simple, namely it uses the difference between the density of the air outside and inside.
- mechanical - works by regulating air exchange. The movement is forced by fans that are part of the installation. It is very efficient.
- hybrid - combines gravity and mechanical ventilation solutions. In a situation where gravity ventilation is insufficient or unprofitable, mechanical air exchange occurs.
How to take care of the ventilation system?
The ventilation system should be efficient, because thanks to this you can enjoy healthy air, but also avoid problems with fungi or mold. However, you need to remember one important thing, namely that the ventilation system needs to be taken care of. It is recommended to clean the ventilation ducts once every few years. Most often, it should be done every 5-6 years. Thanks to this, you can avoid major failures. The mechanical ventilation system in particular needs to be taken care of.
It is also worth remembering that there are symptoms of improperly functioning ventilation. They include:
- steamy windows
- condensation water on windows
- the appearance of moisture in the house
- the appearance of an unpleasant odor in the house
- noise from the fan
These symptoms indicate that specific components may be damaged. You should also remember to replace the reduction, which may wear out. Here, we recommend galvanized models, which are resistant to corrosion, but also loads or even heating. It is also worth considering replacing sleeve , which is used to connect fittings and in this case it is also best to choose a galvanized model. An important role is also played by fans , which can be damaged and, if necessary, can also be replaced.
In addition, the ventilation duct systems should be inspected regularly. It is best to do this at least once a year. In this way, you can avoid major failures that would be expensive to repair.
Heat recovery ventilation - why is it worth checking the filters?
Mechanical ventilation recuperators are equipped with filters, which are essential accessories for recuperation . They play a very important role, as they protect the heat exchangers from getting dirty. Filters need to be replaced. Their condition can most often be checked by pulling them out of the cassette located on the housing. If the colour is dark grey, it means it is high time for replacement. If the recuperator is older, the front panel should be unscrewed. If the filter is slightly dirty, it can be vacuumed and reinserted into the cassette. You also need to take care of the air intake and exhaust. It is best to clean them in the spring, when plant pollen production is high. You also need to clean the intake in the autumn, as leaves can get into it. Every few years, you need to clean the ducts using an air brush.
How to choose a roof fan and when is it used?
In places with a low level of air pollution, roof fans are used . They can be elements of a mechanical ventilation system, but they also support natural, or gravitational, ventilation. They are responsible for removing polluted air and maintaining it at a safe level. For ventilation to work effectively, you should choose roof exhaust fans that have a single-phase electric motor. The winding should have overload protection. Thanks to a roof fan, there is no need to use an air intake or exhaust. Its maintenance and possible replacement are simple and quick.
