To open or not to open windows when using a dehumidifier is a big topic of discussion, often resulting in several conflicting answers. We've always been taught to open our windows frequently to allow for natural ventilation and prevent damp inside our homes; however, if you've already enlisted the help of a dehumidifier, is it still necessary to keep your windows open?
Before the best dehumidifiers were around to tackle indoor humidity issues, leaving a window open has long been a reliable way to try and prevent the build-up of damp. This is especially true in specific areas in our homes that are more prone to moisture issues, such as bathrooms and kitchens. However, if condensation and mould are persistent issues you keep encountering on a day-to-day basis, it's time to take these as a sign that you need a dehumidifier ASAP.
