Cool Mist Humidifiers Explained

A cool mist humidifier is an electronic device that works to release tiny water vapor droplets into the environment. They can do this in a few different ways depending on the type of humidifier you are using.

— Ultrasonic Humidifier

The Ultrasonic humidifier is the most popular option for bedroom and small areas, such as home offices. They use an ultrasonic plate that vibrates to create fine water droplets that are then blown out via a fan. Many of these can also double as a diffuser and be used with essential oils.

— Evaporator

 

Evaporators are more popular for larger spaces, such as living areas or large bedrooms. These units use a filter or wick that draws up water which is then blown into the room. They are a bit more effective than an ultrasonic unit, but do require regular filter changes and maintenance.

Humidifier Benefits

Using a humidifier as instructed has some awesome benefits you can take advantage of. Be sure to use a unit that works for the space you need moisture added to, and keep in mind that small units work well to help direct moisture where you need it- such as while you sleep. Look over the many reasons why you might want to add a cool mist humidifier to your space.

  • Ease and help reduce snoring
  • Keeps skin moisturized
  • Soothe symptoms of allergies and respiratory illness
  • Create a less favorable environment for airborne virus spread
  • Support clear airways
  • Protect and lubricate sinuses and throat
  • Help with winter and summer temperature control
  • Reduce and prevent static
  • Keeps wood furniture from drying out
  • Helps support healthy houseplant growth

Issues to Pay Attention To

You do need to pay close attention to the use of a humidifier however. A dirty unit can grow mold and mildews and then introduce them to your air. Always clean them according to directions, and try using distilled water whenever possible to avoid hard water mineral buildup.

Using a humidifier in a humid environment can also lead to excess moisture that can settle on surfaces and create problems with mold or mildew. It can also make your room feel stuffy or thick. Many units have controls over how strong a mist you want used, so be sure to control the amount of moisture you are introducing.

You also want to be very careful about placement since you are dealing with both water and an electrical source. Also, you don’t want moisture buildup on furniture or books.
