Are Ultrasonic Humidifiers Effective?
Yes, ultrasonic humidifiers work very well.
They are quiet and inexpensive. Plus, you can find them in a wide range of sizes.
They contain a diaphragm that vibrates at an ultrasonic frequency. The vibration breaks water down into a fine mist. (1)
There are two downsides to an ultrasonic humidifier. But these are easy to rectify with a little bit of care.
First, if you fill an ultrasonic humidifier with hard water, it’s likely to leave white dust on nearby furnishings. But if you fill it with distilled water or use a demineralization cartridge, this problem goes away.
Second, cool mist humidifiers (like most ultrasonic models) can spread microbes if they aren’t cleaned regularly. Again, frequent cleaning or the use of a purification cartridge solves this issue.
Which Is Better: A Cool or Warm Mist Humidifier?
Ultrasonic models are usually cool mist humidifiers. But some disperse warm mist.
Cool mist is safest around children. But warm mist boils away pathogens to emit pure vapor.
In either case, although warm mist may feel comforting, by the time the moisture reaches your lungs, the temperature is about the same.
What Are the Differences Between the Different Types of Humidifier?
Ultrasonic humidifiers are advantageous as they generally don’t require a filter. This cuts down on the long-term cost of ownership.
Evaporative humidifiers rely on a filter that needs to be changed every few months. Many times, they also depend on a fan to disperse the water vapor, and that makes them a little noisier.
Using a Humidifier Solves Problems
Dry air below 30% relative humidity leads to a variety of problems.
People who live in homes in desert climates and those with central air and heating know exactly what we’re talking about.
Their skin, eyes, hair, and mucous membranes are dry. Their body feels itchy, and they tire of static electricity shocks.
Their musical instruments, wooden furniture, art, and books may warp and become brittle.
Worse, flu viruses spread easier in dry air (2). And it’s harder to deal with asthma, allergies, and congestion if the air is too dry.
Medical experts recommend keeping your home between 30 to 50% relative humidity to protect your health and your belongings (1).
An inexpensive hygrometer will show you the amount of humidity, or the humidifier itself may display this information.
Take Good Care of Your Humidifier and It Will Take Good Care of You
The EPA reminds us that a dirty humidifier can spread bacteria and mold (3).
Moreover, the American Academy of Allergy, Asthma & Immunology warns about over-humidifying your home. Too much moisture helps dust mites thrive (4).
Be sure to follow the instructions for cleaning your humidifier. If you anticipate that you might not be up to the challenge, invest in cleaning cartridges and filters to do the job for you.
If you’re not sure how to clean your humidifier, avoid disinfectants and cleaning products except for hydrogen peroxide. A 3% solution will disinfect the water tank. Then be sure to rinse thoroughly to remove any residue.
Now, let’s help you find the best ultrasonic humidifier for your needs.
