A Breath of Fresh Air: How Humidifiers Work

First, a quick humidifier overview. These appliances contain a tank or reservoir that is filled with regular tap or distilled water by the user. The water is then dispersed into the indoor air in the form of a light mist.

There are three main ways humidifiers create this mist:

  • Evaporation: A wick filter absorbs the water which evaporates into the air.
  • Steam vaporization: The water is boiled to create steam.
  • Ultrasonic vibration: A metal diaphragm vibrates at a high frequency to create water droplets.

No matter the dispersion method, the result is the same. The added moisture increases the relative humidity level in a room. This makes the air feel less dry and much more comfortable!

Now let’s explore why increasing humidity is so beneficial.

Perk Up With Soothing Humidity

Running a humidifier provides some great perks:

  • Alleviates dry air irritation like itchy skin, scratchy throat, sinus congestion and bloody noses. Humidity makes everything feel soft and moisturized.
  • Prevents static electricity buildup that can damage electronics and cause zaps when touching metal objects.
  • Lessens cracking and warping of furnishings, wood floors, musical instruments and more.
  • Hydrates indoor plants so they can thrive. Makes your little green friends happy!
  • Eases cold, flu and allergy symptoms. Hydrates irritated membranes in the nose and throat.
  • Reduces airborne viruses and bacteria. Many can’t thrive in humid conditions.

With benefits like these, it’s easy to see why humidifiers are handy devices to have around!

Now let’s move on to picking the right one for your needs…

Choosing Your Ultrasonic Hero

Ultrasonic cool mist humidifiers are a popular type of humidifier. They use high-frequency vibrations to create a cool, invisible mist without heat or fans. This makes them quieter and safer than other options.

Here are the key factors to consider when shopping:

Tank Capacity

  • The larger the water tank, the less often you need to refill it. Look for a 1-1.5 gallon tank for medium rooms and 2-3 gallons for large spaces.

Run Time

  • Longer run times between refills mean less maintenance. Look for ultrasonic models with at least a 24 hour run time on lower settings.

Coverage Area

  • Check the product specs for the recommended room size. More powerful units can disperse moisture across 600 – 700 square feet.

Mist Output

  • Measured in gallons/liters of moisture output per day. Look for at least 3 gallons or 11 liters daily.

Runtime Settings

  • Variable fan speeds let you control the moisture output. Auto shutoff when empty prevents damage.

Noise Level

  • Ultrasonic models operate at less than 50 decibels for peaceful, quiet performance.


  • Automatically monitors and adjusts moisture output to maintain an ideal humidity level. Set it and forget it!

Water Tank

  • Transparent tanks make it easy to monitor the water level. Handles allow easy transport for refilling.

Extra Features

  • Air purification filters, essential oil diffusers, night lights and remote controls provide extra functionality.

Ease of Cleaning

  • Mineral deposits can build up – ensure all parts are dishwasher safe. Look for cleaning reminders.


  • 1-3 years of coverage for defects indicates better expected quality and lifespan.

Tips for Ultrasonic Humidifier Success

You’ve got your new ultrasonic humidifier home – now what? Here are some tips for safe, effective operation:

  • Place it on an elevated, hard surface rather than the floor or carpets which can get damp.
  • Use room temperature tap water rather than cold to maximize mist output. Or use distilled water to limit mineral buildup.
  • Change filters as recommended to ensure proper performance.
  • Keep humidistat between 40-50% relative humidity for optimal comfort and health.
  • Clean it regularly with vinegar or disinfectant to prevent germs and mineral deposits.
  • Absorb excess moisture by occasionally opening a window.
  • Run it constantly on a low setting rather than on/off to maintain steady moisture levels.
  • Adjust settings seasonally to account for changes in ambient humidity outdoors. Shut off between uses to prevent mold growth in the stagnant water.
  • Use a hygrometer to monitor humidity and verify the humidifier is working as it should.

Following these tips will maximize the convenience and benefits of your ultrasonic cool mist humidifier. Just a little regular maintenance is all it takes!

Humidifier Q&A

Still have some questions about ultrasonic humidifiers? Here are answers to some frequently asked questions:

What’s the difference between warm and cool mist humidifiers?

Warm mist models boil the water to create steam vapor which is released. Cool mist humidifiers use evaporation, impellers or ultrasonic vibration to produce a fine spray without heat. Cool mist options are typically safer since steam can cause burns.

How can I tell if the humidity level is optimal in my room?

30-50% relative humidity is recommended. To monitor levels, use a hygrometer which measures moisture in the air. Below 30% can cause dry skin, irritation and static electricity buildup. Above 50% encourages mold, bacteria, and allergens.

How should I clean an ultrasonic humidifier?

Follow manufacturer guidelines, but generally you can use a combination of white vinegar, hydrogen peroxide, and bleach to descale and disinfect the tank and interior parts. Always rinse thoroughly after cleaning. Replace filters as recommended.

What causes white dust with ultrasonic models?

White dust is mineral deposits left behind by tap water as it evaporates into the air. To avoid this, use distilled or filtered water or use a demineralization filter cartridge.

How long can I expect an ultrasonic humidifier to last?

With proper care and maintenance, an ultrasonic humidifier should last 3-5 years. Look for models with 1-5 year warranties when purchasing for an indication of expected quality and lifespan.

I hope these answers helped clear up some common points of confusion around ultrasonic humidifiers!
