The Best Humidifiers Option


Heating and air conditioning strip your home’s air of its natural humidity. The result of uncomfortable dryness leaves your skin feeling dehydrated, contributes to sinus and respiratory problems, and even promotes static electricity—that annoying shock you get every time you cross a carpeted room and touch the television.

A little added moisture in the air helps alleviate dust mites and soothes irritated nasal passages. In addition to a handful of household hacks, homeowners can rely on humidifiers to help the situation. Humidifiers have been around for decades but today’s models offer more choices than ever before. We’ve done the legwork and found out what features buyers want most in humidifiers as well as which models they rate as the best humidifiers.

Keep reading to learn all about today’s room humidifiers and to discover why we’ve selected these as top choices, depending on your home and your needs.

What to Consider When Choosing the Best Room Humidifier

Warm Mist vs. Cool Mist Humidifiers

Both cool and warm mist humidifiers add much-needed moisture to dry indoor air, with slight differences:

  • A standard warm mist humidifier brings water to a boil to inject the room’s air with a little extra moisture. The high heat reduces the risk of bacterial transmission, leading it to be considered slightly healthier. Warm mist humidifiers are also typically quieter to operate since steamy mist naturally rises, eliminating the need for an internal fan. They do require additional cleaning because the boiling process leaves behind mineral deposits.
  • A cool mist humidifier uses a fan to blow air through a damp wick, so it can be noisy when it turns on. Cool mist humidifiers are preferable to warm mist humidifiers in homes with small children since there is no danger of burning little fingers.

Ultrasonic Technology

Ultrasonic humidifiers can disperse a warm or a cool mist, or both. The cool mist option is more common, but some models include an internal heater that facilitates a cool mist in the summer and warm mist in the winter. Instead of utilizing a strong fan, as your standard cool mist humidifier might, an ultrasonic humidifier breaks up water droplets into mist using a ceramic diaphragm that vibrates at a frequency too high to be audible to the human ear. Best of all, most ultrasonic humidifiers are whisper-quiet, so they won’t interfere with your sleep.


A humidifier that is too small may not be sufficient, while one that’s too large could add so much moisture in the room that droplets appear on furniture and other surfaces. Fortunately, humidifiers are rated by the intended room size. A small room humidifier effectively treats rooms with less than 400 square feet of floor space. They are often portable and lightweight, making them a good choice for bedrooms, nurseries, kitchens, and other small rooms. Medium-size room humidifiers treat rooms between 400 to 900 square feet and are only semi-portable. For a room with 1,000 square feet or more, look for a large room humidifier. Large room humidifiers feature bigger water reservoirs and are stationary.
