This is because humidifiers are so essential to help babies, toddlers, and beyond to breathe easier during allergy and cold seasons. In the winter months, when the air can be dry and uncomfortable, humidifiers help to add moisture to the air.

What to Look for When Buying a Humidifier 

Water Capacity 

Because a humidifier works on putting moisture back into the air, it’s important to double check the water capacity. When you’re ready to purchase a humidifier, determine which room the humidifier will be staying in and if there’s enough water to cover the entire room. Too little or too much water can ultimately cause damage or not solve your sinus/dry air issues.

Some humidifiers can hold a lot of water but give you the option on how much humidity you can put back into the air. For example, a humidifier with a large water capacity may work better for you if you plan on running it all night long at a high speed. However, if you’re needing it in a small room for just a few hours, you can opt for a smaller water capacity. 

Auto Shut-Off

One of the most important features to consider when shopping for a humidifier is an auto shut-off option. This not only ensures the humidifier is turned off when the desired humidity level is reached, but also if it runs out of water. 

Many families like to leave a humidifier on while everyone sleeps, but this means the humidifier can run out of water when no one is watching. With the auto shut-off option, the humidifier avoids any potential damage and you and your family can sleep in peace.

Room Size

Whether the air is too dry in your home or you’re having sinus problems, it’s no secret that’s when humidifiers can really save the day. However, how they work depends largely on the size of the room the humidifier will be staying in. Some humidifiers are designed to cover small spaces, like rooms that measure around 250 square feet, while others are made for larger rooms. 

For example, if you buy a humidifier that’s too small for a large room, it will not cover the entire room. It’s similar for small rooms with too much water going into the air; using too much water from a humidifier can actually cause water damage over time if you’re putting too much moisture into the air in a small space.
