Excessively dry air in our homes can lead to a number of problems. It’s bad for the structure of your home as well as for furniture and carpets, and can make our homes feel less comfortable. Mist humidifiers are helpful for raising home humidity levels, but that moisture comes at a cost.

Operating humidifiers increases your electric bill and your overall carbon footprint, due to the emissions associated any new electronic. There are a few approaches to increasing the humidity in your home without a machine, like adding houseplants and using shallow dishes of water. However, if you tried to naturally humidify your home yet still need more moisture, you can invest in an energy-smart machine.

Although Energy Star doesn’t rate humidifiers, it does certify air purifiers so you can find some dual-purpose devices with the Energy Star seal on the market. You can also contact the manufacturer directly to find out about the energy-efficiency specs of the product. We've made it even easier by identifying some of the best eco-friendly and energy efficient humidifiers, among other high-quality options to consider.

What to Consider When Shopping for a Mist Humidifier

Cool vs. Warm Mist

There are both cool and warm mist (aka steam vaporizers) humidifier options. Warm mist models use a heating element to boil water and make steam, so keep these out of reach of children or pets. This variety is better for reducing bacteria and germs, but avoid them if you have a cold because they can swell nasal passages, making it harder for you to breathe.

Cool mist humidifiers are more widely used. They come with a fan that evaporates water into the air. This can add a chill to the air, so they may be a great option if you live in a warmer, drier environment.

Filters and Cleaning

No matter which humidifier you buy, cleaning it regularly is a chore. However a few humidifiers, like the BONECO W200, can be placed in the dishwasher for sanitizing.

It's always a good idea to look at how often the manufacturer recommends cleaning the tank and base, and how often you need to replace the filter. Some units even have two filters that need to be swapped out, which can add expense to operating the device. We also don't like that most filters can't be recycled, which is another disadvantage of mist humidifiers generally.

Size

Follow Goldilocks' “just right” rule and match the model you buy with the room size, to make it easier to maintain the humidity level that you want. You can also consider portability, which will allow you to take one machine with you into different rooms rather than having multiple machines running simultaneously. Smaller units may even be possible to travel with, if dry air tends to bother you in hotel rooms.

Additional Features

Look for models that include air purifying filters, automatic shutoffs, and mold resistance to bacteria that may build up inside the machine.
