2. Add a portable humidifier (or dehumidifier)
During the winter months, when drier air leads to scratchy throats and runny noses, having a floor or portable tabletop humidifier makes a huge difference. A device like this basically moisturizes a room’s air so it reaches healthy ranges — estimated to be around 35-50% humidity, depending on the weather.
Choose one that has enough power for the size of the room, and consider buying a model that comes with a built-in hygrometer, which provides automatic humidity control. Now, if you’d like to have a device like this in several rooms, you should consider investing in a whole-home humidifier.
On the flip side, if you want to take moisture out of the air, keeping a dehumidifier in the basement or other dampness-prone areas may help you prevent the growth of dust mites and mold.
