Is a cool mist or warm mist humidifier better?
Both warm and cool mist humidifiers will do the job of adding water to the air, which can be great for dry skin, chapped lips and stuffy chests, especially in babies.
Cool mist humidifiers can be ideal for children as they can be quieter than warm mist humidifiers and there’s no risk of them hurting themselves on the hot water. You do have to clean the tank more regularly and thoroughly though as bacteria can grow. The heating process in warm mist, on the other hands, helps to stop any bacteria that may have grown from being distributed into the air.
There are two ways the water can be distributed. Evaporative humidifiers draw air through a moist filter, whereas ultrasonic humidifiers use high-frequency vibration to create water droplets that are distributed via a fan into the air. Users say hard water can affect the ultrasonic process so bear that in mind or use distilled water if you live in a hard water area.
What should I look for when buying a humidifier?
Size – the size of the unit doesn’t always correspond to the size of space the humidifier can work in or how many hours use you will get out of it. Generally though, the larger the tank the longer the humidifier will work. Tank sizes vary from 200ml for personal use humidifiers to six litres or more for whole house humidifiers.
How easy it is to clean – Warm mist humidifiers are designed to heat the water and reduce the risk of bacteria or mould being pumped into the air. Cool mist models don’t have this function so need to be cleaned more regularly according to the manufacturer’s instructions. However, both options need to be cleaned frequently often with a mild bleach like Milton. Look for models where you can remove the water tank easily and ones without fiddly crevices that are hard to scrub.
