With open windows, you are guaranteed at least some additional airflow and circulation. While airflow and circulation help get rid of moisture on their own, they also introduce more air into the inside environment. Dehumidifiers work best in a sort of “closed-loop system,” where the same air stays in.
It depends if you want a freezing cold house. In the summer we open windows. In this weather if rather keep the heat so use the dehumidifier. Also if it's really cold and damp outside then opening windows isn't going to dry things out as well as the dehumidifier will.
Opening the windows would only be allowing humid air into the room. You should also keep the windows closed when there is cold weather or if it is raining but the exception to this is if you are having a hot shower or cooking then your windows should be open.
While it may seem counterintuitive, it is actually helpful to open the windows and remove the stale, dry air from your house. Open windows during the daytime to let the fresh air in. It will help you breathe easy, and your skin won't feel that dry and itchy. Plus, it will also improve your home air quality.
Set the Right Humidity
To get your manually-controlled dehumidifier up and running, set its humidity level. You want it set at 30 – 50%. If there's too much moisture, you'll get dampness and mould. If there's too little moisture, your home will be too dry and attract bacteria.
A dehumidifier typically needs between 24 and 72 hours to completely dry out a room. It's critical to continue using the dehumidifier until the humidity levels are normal.
Can I leave the dehumidifier running at night? Yes, we recommend using a dehumidifier 24hrs, however, be aware that there will always be a noise generated from the machine when it is operating.
If the outdoor air is already humid, then opening the windows will almost certainly increase the moisture levels indoors. In that case, you may not need to run a humidifier when the windows are open.
Condensation occurs when humid, warm air becomes trapped in your home and then meets a cold surface, like a window. Opening a window allows humid air to escape from your home, thus reducing condensation.
Keeping a window open reduced concentration of carbon dioxide, volatile organic compounds, and some particulate matter in participant bedrooms. People slept better. Keeping a door open also reduced carbon dioxide concentration, without a direct correlation to improving sleep.
The short answer? Yes. 'Ventilation is key to preventing mould growth,' says Jordan Chance, product manager at PlumbNation. 'Make sure to leave bathroom windows open for at least 10 minutes after showering and bathing in order to clear excess moisture from the atmosphere.
So to recap, run your dehumidifier unit for at least 12 hours a day. This is a good rule of thumb. Again, it's okay if you don't stick to this schedule every day, but be aware that the more your family runs your dehumidifier unit the fresher and cleaner it will be all year long.
Avoid putting it in the bathroom, too. 'We don't advise using a dehumidifier in the bathroom because it isn't IP rated,' says Meaco's Chris. 'But positioning a dehumidifier as close to the bathroom as possible with the door open still can help to reduce moisture quickly. '
Can you dehumidify too much? There is a chance of dehumidifying your home too much with a dehumidifier, especially if you are leaving your dehumidifier running for several hours on a timer unattended. Over-dehumidifying your home can lead to an increased chance of respiratory illnesses and dry and cracked skin.
air exchanger that modifies the humidity while overturning the air. To prevent these issues, it is recommended to keep windows closed in humid areas and consider investing in a dehumidifier to control moisture levels.
The most common condensation solutions are based around controlling humidity in your home and improving ventilation. To stop condensation forming on the walls in your bedroom, kitchen, or bathroom, you should: Open your windows to allow air to circulate more freely.
Open Your Window
This might seem obvious, but it's effective. Opening your windows will release the humid air outside, and therefore, will prevent the humidity from collecting onto your windows. So, if it's not too cold out and you're suffering from condensation, open a window.
Research from the Building Science Corporation found that humidity of 70% or higher adjacent to a surface can cause serious damage to the property. The Health and Safety Executive recommends that relative humidity indoors should be maintained at 40-70%, while other experts recommend that the range should be 30-60%.
During the winter, if you open the window when the outside air is colder than the air indoors, the cold air will come into contact with the warmer air and the level of humidity will fall automatically.
Prevailing wisdom is that at least 5 minutes—and ideally 15 to 20 minutes—a day of ventilation significantly improves indoor air quality. For a strong ventilation, open the front and back door, along with windows on the path in between, to get the baddies out.
Yes it is perfectly safe to sleep in the same room as a dehumidifier. If you are particularly interested in a dehumidifier for the bedroom the noise level will be particularly important to you. The quietest model we offer is the compressor-free DNC65.
Mold stays “dormant” in the air or on surfaces even when there's no excess moisture to help it grow. If the humidity in a room increases, mold will start growing in patches on walls, clothes, and more. So, to answer your question, dehumidifiers do NOT kill mold, but they do prevent it by reducing humidity.
Not only is it safe to sleep with a dehumidifier on, but it can also bring some surprising benefits. One of the main advantages of using a dehumidifier while sleeping is reducing allergens and irritants like dust mites, mould, and mildew that thrive in high humidity.
