FAQ About Humidifiers

It's not just a lot of hot air -- a humidifier can do wonders to improve the air quality in your home. Here we answer a few common questions to explain the basic function, different types, and available features, so you can choose the best air humidifier for your needs.

What is an air humidifier used for?

A humidifier is a device that converts water to mist or vapour in order to raise the humidity, or moisture level in the air, in a single room or even an entire building.

What are the benefits of a humidifier?

Improving the humidity in your home or workspace offers numerous advantages to your comfort and health. Dry air in winter contributes to dry skin and sinuses. A humidifier provides relief and contributes to better sleep and healthy skin. It reduces the spread of airborne viruses like the flu, which move slower in moist air. It's good for wood furnishings and musical instruments, helps reduce static, and makes air feel warmer, so you can turn down the heat and save money.

What are the different types of humidifiers?

All air humidifiers use water to add moisture to the air, but the three common types of these devices do so in different ways.

Cool Mist Humidifiers

Also known as evaporators, these devices work by blowing water through a special filter and releasing it as a mist. They are the most popular variety of humidifier due to their simple and safe operation. These are the best choice for use around small children since they don't boil water and can't cause accidental burns.

Warm Mist Humidifiers

By boiling water to produce sterilized mist, these steam vaporizers require no filters and are generally less expensive. They often have medicine cups that allow you to add cold and flu medication to further soothe cough and congestion.

Ultrasonic Humidifiers

Safe, energy efficient, and low-cost, these humidifiers use fast vibrating metal plates to create a fine mist that's blown out with a fan.

What features should I consider in a humidifier?

Choose a humidifier with the power and capacity to effectively increase the moisture level for your space. Consider the tank size, and how long the unit will operate before requiring a refill. Features like LED indicators or empty tank warnings may prove convenient. Timers, automatic shutoff, and even humidity sensors and automatic operation are available on some models. Many offer quiet operation, and some include an aroma function that lets you add fragrance.
