Are Dehumidifiers Safe?

Updated April 17, 2017

A dehumidifier is a machine that removes moisture in the air, collecting the resulting water into a small plastic container that you must empty on a regular basis. Although there are several disadvantages to using a dehumidifier, they are safe for many uses and even have health benefits.

If you have water stains on your walls and ceiling or any musty, mouldy areas of your home, you may want to consider using a dehumidifier. Dehumidifiers prevent the growth of mould, mildew and dust mites--all three of which thrive in damp, humid conditions.

Health Benefits

Using a dehumidifier can help reduce allergies from dust, mould or bacteria in the air. You can also relieve asthma symptoms by using a dehumidifier. Removing moisture from the air helps control dust mites, which can be particularly harmful to asthma sufferers.

Risks & Disadvantages

If you don't clean your dehumidifier regularly, the water and damp conditions may cause mould to grow. If the air in your home is already dry and you use a dehumidifier, this may result in chapped lips or skin, a sore or scratchy throat and excess static.
