The difference between humidifiers and dehumidifiers

Discover the differences between these products and how they balance the moisture in the air with our handy guide.

Humidifiers and dehumidifiers help you manage the moisture in the air, so they’re great for combatting the effects of indecisive weather. They both improve the air quality in your home, but the difference is how they work and the best time to use them. In our handy guide, we’ll tell you what these products do and some of the health benefits of them.


A humidifier increases the moisture in the air. They push an invisible mist out that adds moisture into the air and they can help stop headaches, sore throats, dry skin and other conditions that thrive in a dry environment. They also protect things like wooden fixtures, antiques and musical instruments from cracking or splitting, so a humidifier can also help your home stay in tiptop shape too.

Too much moisture in the air creates the ideal environment for damp and harmful moulds to grow, which can make allergies worse. They’re ideal for use all year round – especially where ventilation is an issue. For example, during winter months when you have the heating on, windows closed and clothes drying on the radiator. They work by sucking in warm air like a vacuum and reducing the amount of moisture in the air. Moisture is then collected in a tank that you simply pour away, so there’s no need for an external drain. They can really help to reduce hay fever and asthma symptoms, so they’re great for those who suffer with allergies.
