Dry air, caused by a lack of humidity, can cause a dry throat and coughing. This can lead to a restless or disturbed sleep - particularly in winter, with the heating on and less outside air coming into the house.
An air humidifier can help alleviate dry coughs, so you get a better night’s sleep. Evaporative humidifiers also control the spread of bacteria to keep your home healthy. When it comes to selecting an air humidifier, one choice you’ll need to make is between ultrasonic or evaporative.
