September begins, and with him the first fresh days and the humidity that insinuates himself silent between the walls of the house are coming: 3 wrong behaviors are enough to increase it by 20% and create condensation also with external 18 ° C and closed windows. In many homes, especially the most isolated or not very ventilated, this phenomenon is more frequent than it is believed.
A wet house may seem only an aesthetic discomfort, but in reality it affects health, structure and bills. Those who have tried to manage humidity know it well: a small mistake is enough, and the air returns to become heavy within a few hours. Fortunately, knowing what to avoid is already a step forward.
In some tests conducted in internal environments with north exposure and poor ventilation, it was found that the incorrect management of domestic ventilation can bring the humidity rate up to 70% in less than 48 hours. An insidious situation, especially in September, when the days still seem warm, but the walls already begin to “drink” excess humidity.
The laundry lying in the house: Error No. 1 underestimated
Many do it, often without thinking about it: hanging the clothes just washed inside the house seems the most comfortable solution when it is cloudy or it rains outside. But one of the main managers of domestic humidity lurks here. Each load of washing machine releases Up to 2.5 liters of water in the air during drying. If there is no effective ventilation system, this steam deposits on walls and windows, creating condensation and, over time, molds. Even in well -heated environments, the effect can be deleterious. The water vapor tends to rise, cool down and condense on cold surfaces such as glasses or little sunny corners.
Many do not notice them until there are halos or small dark spots on the walls. After all, who has never thought: “But yes, is it just for today …”? Spreading the laundry in the house without helping well is like turning on a full -speed humidifier, but without your knowledge.
Kitchen without hood: a silent but constant error
During the preparation of meals, especially in autumn, the kitchen environment becomes a real steam generator. Boil pasta, prepare soups, steam cooking: each activity contributes to increasing humidity.
The aspiring hoodoften forgotten or unused, is instead essential. Not using it means letting all that steam spread in the living room, corridor, rooms, where it cools down and condensation.
In homes with open cuisine, the phenomenon is amplified. The steam moves quickly, making the air thick even several meters from the stove.
In addition, many people leave the lid on the pots thinking they contain the humidity. In part it is true, but without adequate aspiration, the steam will still end up going out and “leaning” everywhere.
A technician who works in the renovation sector said he took over values over 75% of relative humidity in kitchens without working hood, after just an hour of cooking.
Windows closed all day: the error that makes thehumidity in the house
September brings an uncertain climate, and instinct is that of keep the windows closed To avoid sudden currents or cold. But in doing so, a perfect microclimate is created for humidity.
Even without rain, the internal air tends to saturate themselves as a result of breathing, daily activities and simple human presence.
Never open the windows is like sealing humidity inside the house. Enough an hour of morning ventilation, even just 10-15 minutes with crossed currentsto drastically improve air quality.
In some homes tested after 3 days with always closed windows, a 25% increase in humidity was detected compared to the norm, with evident signs of morning condensation on the glass.
Better to have a little more fresh than an less wet wall: thermal comfort can always be adjusted with one more blanket.
Necessary to limit domestic humidity
To avoid these small-large daily mistakes, it is often enough to rely on some simple but decisive ally. It is a thought that everyone has had at least once, but now it’s time to move on to action with concrete tools:
- Electric dehumidifierto be used in the most humid rooms
- Aspiring hood with external exhaust working and clean
- Digital hygrometer To monitor the humidity rate
- Outdoor folding stenndibiancheryeven from a balcony
- Fans on the floor or windowto create recirculation
- Breathable paints in areas subject to condensation
Having these tools is not enough: it is important to use them with constancy and attention, adapting them to climate and domestic habits.
Conservation and maintenance of dry environments
A dry house remains with small constant controls. There is no need to make miracles, just don’t let the small signals pass unnoticed.
Some useful tips:
- Regularly clean the hood filters, aspirators and dehumidifiers
- Check any infiltrations in the perimeter walls
- Check the status of the windows of windows and doors
- Repair small cracks where humidity insinuates
- Use Absorbiumidity salts in the most closed furniture
A dry home is not only healthier: it is also more resistant and easier to heat in the cold months.
Better prevent today than chasing the mold tomorrow.
