Finding the right ventilation for your bathroom is not difficult. First of all, you need to remember that it must be selected for the size of the room, but also whether there are windows in it or not. A common problem that appears in the bathroom is moisture or mold. It is worth learning more about how to get rid of them.

Why does damp occur in the bathroom?
Moisture, although not dangerous in itself, can destroy grouts and, even worse, lead to the development of mold, which is already harmful. Using hot water causes water vapor to settle, which in turn creates good conditions for the development of fungi, which are the cause of many respiratory diseases, but also the aggravation of asthma. Properly functioning ventilation is crucial. In the case of small bathrooms, gravity ventilation is sufficient, which requires the use of a ventilation grille.
It is worth knowing that the ventilation grille is available in many variants. You can choose a round, square or rectangular one and match it to the aesthetics of the room. Gravity ventilation consists of ventilation channels through which air is sucked out, while clean air enters the interior. This movement is forced by the draft that is created as a result of the temperature difference.
In the case of larger rooms, gravity ventilation is not efficient. Mechanical ventilation , which is enriched with electrical power supply elements, will work better. It uses small fans that are mounted at the outlet of the ventilation duct. When the fans are connected, they work efficiently, creating a healthy microclimate. If the humidity in the room is really high, it also results from leaky windows.
Recuperation, which recovers energy from exhaust air, will work very well. After recovering heat, recuperation transfers it to the incoming fresh air. Hybrid ventilation is also worth noting, which is actually a combination of gravitational and mechanical ventilation. This means that it works on the principle of gravitational ventilation, but if necessary, it is supported by a fan.
How to ventilate the bathroom to get rid of moisture?
It is worth knowing that during a bath in a bathtub about 1000 g of water vapour is released, while in the case of a warm shower from 1500 to 2000 g. Without properly selected ventilation, moisture will appear very quickly, and as a consequence fungus or mould. According to the building law, gravity ventilation can only be used in a room that is larger than 6.5 m2.
Regardless of the surface area, it is necessary to use ventilation ducts that remove 50 m3 of air per hour. Their cross-section cannot be larger than 16 cm, and their length should be at least 2 meters. In addition to selecting the appropriate ventilation, you can also use airing, which should be done at least once a week. It is best to open the windows wide and then close the doors. However, no such method will give as good results as mechanical ventilation , which removes even large amounts of moisture. The power of the device should be at least several times greater than the cubic capacity of the room. Of course, in some cases, gravity ventilation will work, which works on the principle of convection, which means that water vapor rises up and is then drawn in through a ventilation grille connected to the duct. However, its proper operation can be disturbed by strong wind. Therefore, you can choose hybrid ventilation. In this case, the fan will be turned on only in specific situations.
Can ventilation help remove mold from the bathroom?
Proper ventilation helps control moisture in the bathroom, while also preventing mold from forming. However, once it does appear, it must be removed. The most harmful is black mold, which disrupts the immune system, but also promotes the development of asthma. This type of mold is very invasive.
It appears on walls, ceilings and even in silicone joints. It is accompanied by a musty smell. Therefore, in accordance with the principle that prevention is better than suffering the consequences, it is necessary to ensure proper ventilation as soon as possible, which will allow for full moisture control. In warm times of the day, e.g. in the summer, you can additionally open the window.
