Factors to Consider When Choosing the Best Ultrasonic Humidifier

Before you go out in the market or place an order for an ultrasonic humidifier online, it is important to consider several factors first. This way, you will know exactly what to look for among the wide number of available options. These factors include:

Noise

By far, ultrasonic humidifiers are the quietest type of humidifier. However, still, different units create different levels of sounds. While most of the units create noise less than 35 dB, which is barely noticeable, other low-end units may create considerable noise.

In case you buy a model that creates noticeable noise, it can interrupt your sleep and concentration while working. Hence, we suggest you always go for an ultra-quiet model, regardless of its price point.

Tank capacity

The maximum tank capacity of ultrasonic humidifiers is a direct indication of the area that they can cover. Typically, most of the humidifiers with a medium-sized tank can humidify from 200 to 500 square feet of area.

Though expensive options may be able to humidify an even greater area, the tank size may also directly determine the speed of humidification. In case you aim to humidify the entire house, consider choosing whole-house humidifiers.

For as long as you only want to use it in a small room or office, a compact ultrasonic humidifier will do the trick.

Ease of cleaning

It is highly crucial to clean the humidifier from time to time so that it can work efficiently. If not, you will be giving way to harmful bacteria or other microbes. Since all ultrasonic humidifiers do not have an ergonomic design, some can be hard to clean. This means that the far to reach corners in such units can become a breeding ground for bacteria.

This is especially true for the ultrasonic humidifiers that are shaped like a water droplet. Of course, they are pleasing to look at. But they do not certainly have the best design from a cleaning standpoint.

Budget

Lastly, whatever you buy is directly determined by your budget. It is not true that an expensive humidifier is the best option. Typically, the high-end ultrasonic humidifiers come with a wide number of advanced features that you may never use.

In case you just want to humidify your bedroom or a small office room, then a medium-end compact humidifier will do the trick. However, if you are planning to humidify the entire house, then do not stick with the cheaper options.

Hence, the amount of money that you should spend directly depends on the functionality that you are expecting. Of course, expensive humidifiers are made of better materials and tend to last longer due to their sturdy build.

Ultrasonic Humidifier and Evaporative Humidifier

When you are going to buy a humidifier for the first time, you may look for an ultrasonic vs. evaporative humidifier comparison. To help you make a better choice, I have outlined the major difference between both of them below:

Ultrasonic humidifier

Ultrasonic humidifiers produce a very fine mist by using sound vibrations of high frequency. This mist is then expelled into the environment, to increase the moisture in the room. Since it does not boil water, it is very quiet in comparison to the evaporative humidifiers.

People usually prefer ultrasonic humidifiers over evaporative humidifiers due to their safety. It is safe to be used around with kids or pets as it does not contain any hot water.

Evaporative humidifier

Evaporative humidifiers are a more traditional form of humidifiers. In this type, a fan is used to expel tiny droplets of water into the air. Generally, this is considered to be a much more efficient way of humidifying the room.

However, since these humidifiers use a fan, they tend to create more noise in comparison to ultrasonic humidifiers. Hence, they are often not preferred for use over-night.

In comparison to the ultrasonic humidifier, evaporative humidifiers are cheaper. However, ultrasonic humidifiers come with more attractive design options with high-end technological features. In that sense, they are more effective for use despite being slightly more expensive.
