The cold, winter months mean that we often have to turn the heating up a notch. While this creates a toasty, warm home, it may lead to a drier atmosphere, which can affect everything from your skin to your sinuses.
The good news is that a humidifier will help to combat these problems by increasing moisture levels.
However, there isn’t a one-size-fits-all when it comes to humidifiers. You’ll find that there are two main types to choose from: ultrasonic and evaporative.
While both kinds increase humidity by adding water vapor to the air, they do this slightly differently.
Ultrasonic VS Evaporative
Evaporative humidifiers simply speed up evaporation by heating water and using a fan to distribute the vapor produced. They offer a budget-friendly, effective means of adding moisture to your space.
An ultrasonic humidifier, on the other hand, utilizes vibrating plates to create a fine mist without the need of heating, although this usually comes at an increased cost.
Another key difference is that evaporative humidifiers also come with a filter to help to trap impurities. This is a big bonus over ultrasonic units, as humidifiers are prone to emit airborne contaminants such as bacteria, mold and mildew which can make you unwell if inhaled.
With various models out there, we’ve put together our top eight recommended evaporative humidifiers to help you find the right one for your space.

8. Sunpentown SU-9210 Digital Evaporative Humidifier

Frequently Asked Questions About Evaporative Humidifiers
Like any home appliance, humidifiers come in different sizes, technology, and costs. In the past, an evaporative humidifier cost considerably less than an ultrasonic humidifier, but today the price difference is dwindling.
Suppose you compare like for like, then, generally speaking. In that case, evaporative humidifiers cost less than an ultrasonic humidifier but what you might save in initial outlay could be eaten up in maintenance items like the wicks/filters that need to be replaced every so often.
Depending on the model, some filters require replacing every two to three months, and the cost of these wicks/filters can also vary from model to model.
The principal differences between Ultrasonic and evaporative Humidifiers are their method of generating steam or moisture, their noise levels, and their maintenance requirements.
Ultrasonic humidifiers use high-frequency sound vibrations to introduce moisture into a room. This method is generally very quiet but not totally silent. You may feel the vibrations, but the human ear cannot hear the sound at such a high frequency.
Evaporative humidifiers use a fan to blow air over a wet filter into a room. This increases the surface area of the water for evaporation, increasing the amount of moisture in the room.
The short answer to this question is NO.
The white dust everyone is concerned about when using a humidifier is a byproduct of certain minerals found in water that enters the humidifier when it pumps out humidity.
While it may not be a health hazard, it can accumulate on furniture over time and become annoying.
Since evaporative humidifiers incorporate a wet filter or wick, allowing the water to pass through it before converting it into moisture, the filter traps those impurities. It does not emit any “white dust.”
Only ultrasonic and cool mist impellers cause the dust.
🤔 So… Which humidifier is best for you?
When considering purchasing a humidifier, think about the reasons behind your decision.
Many homeowners use a humidifier to combat problems encountered from dry air, such as dry skin or dry sinuses, and dry air is usually a problem when you heat your home in the winter months.
Selecting the best humidifier will depend on various criteria, including the room size.
And don’t forget to consider other factors such as your health, if you have children, or if you have pets. A humidifier can help with congestion, reduce snoring, fight bacteria and viruses, clear nasal passages, and ease asthma, coughs, and allergies.
Of the two main types of humidifiers, evaporative and ultrasonic, it is worth noting that ultrasonic models do not filter any of the water or air used in humidification. In contrast, an evaporative humidifier traps impurities in a filter or wick.
The size of the humidifier is also important. Do you need a whole-house model or one for a child’s bedroom? If you also want to keep the air clean, you should check out what we think is the best humidifier and air purifier combo.
In the long run, choose a humidifier that will best alleviate your problems and is within your budget.
