What to Look for in a Room Humidifier

Because there are so many small humidifiers out there, it can be difficult to sort through the options and make a selection. The good news is that we’ve scoured the market and vetted the best small humidifiers on the market to bring you our top 7 picks.

We considered the following criteria in making our selections:

  • Size and capacity – We considered not only the size of the unit itself, but the size of the water reservoir and the amount of square footage each unit can effectively humidify. Most of our choices are ideal for small rooms under 700 square feet.
  • Customization – Control is important when it comes to a home humidifier. We looked for models that have variable fan speeds and built-in hygrometers that enable you to customize the humidity level as well as other controls.
  • Runtime – Size is the major determining factor for the runtime of an air humidifier but having multiple settings to choose from helps as well. We did our best to offer a variety of options.
  • Ease of maintenance – No one wants to hassle with complicated maintenance, so we chose room humidifiers that are easy to empty and refill, simple to clean, and easy to operate.
  • Safety features – We looked for small humidifiers that incorporate safety features like automatic shutoff. Not only did we prioritize models that shut off when the water reservoir is empty, but we prefer models with built-in hygrometers to shut off at the desired humidity level.

Some additional factors we considered were noise level, warranty, and operating design. Room humidifiers come in a variety of styles, so we recommend taking the time to learn about the different types to determine which option will best suit your needs.

Now that you know how we made our top picks, let’s take a look at them!
