What Does a Humidifier Do? 

A humidifier is a portable device that increases the moisture content of the air. While whole-home humidifiers exist, they can be very expensive. They may also be an unnecessary expense if you spend most of your time in one or two rooms. Large room humidifiers increase humidity in the spaces you use most. 

While humidifiers use various technologies, they all perform a single function: to increase humidity. Some produce warm mist and others cool, all by absorbing water from a reservoir tank. 

Evaporative humidifiers absorb water through a filter and pass air through the moistened filter to release vapor into the air. Steam humidifiers, also known as vaporizers, boil the water to produce steam. An ultrasonic humidifier uses a vibrating diaphragm to create water droplets in the form of a cool fog. 

If you plan to use a humidifier in your home, it doesn’t hurt to invest in a hygrometer as well. Some humidifiers have one built in but if not, a hygrometer can help you monitor the humidity in your home so you can adjust the output of your humidifier. 

What Are the Benefits of Using a Humidifier? 

Low indoor humidity can cause dry, irritated skin as well as chapped lips. When the air is too dry, it may dry out the mucus membranes in your nose and throat, resulting in a scratchy throat congestion. Low humidity can even increase your susceptibility to colds and flu. 

Winter is a particularly bad time for humidity. Cold air has a lower ability to hold moisture than warm air. As the cold air enters the house to be heated, it reduces the relative humidity in the home. Arid climates may also experience low humidity due to the use of excessive air conditioning. 

By adding moisture to the air in your home, a humidifier can ease dry skin and scratchy throat. It may also ease the symptoms of asthma or allergies and help your body fight off colds, flu, and other respiratory conditions. If you do get sick, a humidifier can help make your cough more productive. 

How to Choose the Right Large Room Humidifier

The first factor to consider when shopping for a humidifier is the size of your space. A small bedroom or nursery may cover under 100 square feet while a large bedroom or open living space could exceed 200 square feet. 

There’s generally no harm in getting a bigger humidifier than you need as long as you make sure the humidity doesn’t get too high. Purchasing a humidifier too small for the space, however, may make it difficult to achieve and maintain the desired humidity level. 

Once you’ve determined the size of your space, think about what kind of humidifier you want. Cool mist humidifiers like evaporative humidifiers are generally safer for use around babies and children. They also tend to run a little quieter, so it may be a good choice for a large bedroom. However warm mist humidifiers may be more effective in reducing bacteria and germs – they can also generally achieve higher levels of humidity than cool mist models. 

Finally, think about what features are important to you. Most humidifiers have an automatic shut-off that prevents the unit from running dry. Consider whether you want a smart model with WiFi or smart home connectivity and whether you want to be able to set a specific humidity level. The other option is a humidifier with different fan settings.

Best Large Room Humidifier Picks

A large room humidifier should have a generously sized water tank. A large reservoir not only enables the humidifier to accommodate bigger spaces, but it may help the unit work longer before running dry. This saves you the hassle of refilling the tank every day.
