Benefits of Filterless Humidifiers

Both filtered and filterless humidifiers are good when it comes to adding more moisture into the air. However, there may be some benefits to filterless humidifiers that trump those of the filtered ones. Here are some of them:

1. Easier maintenance.

2. Reduces costs of maintaining the humidifier.

With a filter, you will need to buy a replacement for it. Some come with permanent filters, but others may have to be replaced every time they are inundated with dirt. If you opt for one that doesn’t come with a filter, you don’t need to worry about buying a replacement filter anymore. Some humidifiers have costly filters and they can add up in the long run.

3. There is usually an antibacterial protection installed.

But what about keeping bacteria, molds and mildew out? That might be the concern of many people when it comes to filterless humidifiers. But the thing about most filterless humidifiers you can find out there is that they are equipped with features and materials that stave off the growth of bacteria and other microorganisms that can grow in the tank and in the internal features of the humidifier.

Important Factors to Consider When Buying the Best Filterless Humidifier

There are so many filterless humidifiers out there that it can be confusing as to which one to choose. To make sure you are buying the right one, use the following factors as a guide:

Tank Capacity. The bigger the tank capacity, the better if you want a longer run time. You would want to make sure it is running continuously during the time you need it. Most people keep it on overnight to help improve their sleep, so make sure it has a capacity that will produce mist for at least 10 hours. However, if you are using it for your baby’s room where you might need to run it for a longer time, you might want something with a bigger water tank capacity.

Moisture Output. The moisture output will tell you how fast it will humidify a certain room. If it has a low moisture output, it might have a hard time humidifying a bigger space. If you plan on placing the humidifier in your living room, or office, for instance, where the space might be bigger, you need to make sure it has a high moisture output.

Variable Setting. It is more ideal to get a humidifier that comes with a variable mist setting. That will allow you to control how much mist it is going to dispense. If you are using it in a small room, a lower mist setting should be ideal. Aside from low, medium and high mist setting, a sleep setting might also be ideal.

Antibacterial Properties. Since it doesn’t come with a filter, it is a must to look for antibacterial features. It should have properties that inhibit the growth of bacteria and many other microorganisms.

Nozzle Functionality. Also consider finding a dual nozzle or one with 360-degrees functionality that will allow it to humidify a room faster. The nozzles should dispense mist in the air more effectively than your standard humidifier.

Ease of Use. You also need to make sure that it can be used without difficulties. The water tank should be emptied out and refilled easily. It should have features that make the tank easier to clean. There should be knobs or touch functions that won’t take a genius to figure out.

Size. Many humidifiers today are compact in size. But they do differ in shapes. Some come in elongated form while others might be fatter, thereby taking up more counter space. How compact the humidifier you are going to choose will depend on where you intend to place it. If you have a small space to begin with, something that takes up a smaller footprint would suffice.

Price. Compare the costs of the humidifiers. Make sure you look for one that has a good price range and will not cost a lot of money to acquire. The price should be justified by the features integrated into it.
