There are some factors that one needs to consider to make the right choice when it comes to filterless humidifiers. In the following section, we have listed the basic factors that will help you select the best one for you.
Tank Capacity: The tank capacity is an important consideration as it determines the time required between two fillings of the humidifier. There are two capacities- small and large with their own set of pros and cons. The small tanks are suitable for those who need the humidifier to run for small intervals while the large ones are suitable for those who use the humidifiers for longer periods in time. Mist Output: This factor shows the amount of mist that the humidifier produces in one hour. There are many models that allow you to customise the settings according to convenience. While considering this factor, you need to make sure that you choose a humidifier with mist output of eight ounces per hour or more as anything below that will not be as effective as you want it to be. Auto Shutoff: The auto-shutoff feature is especially important when you are looking at filterless humidifiers due to their smaller tank capacity. This feature turns off the humidifier when it is no longer needed which prevents overheating and reduces power consumption.
More details on the factors to consider when buying filterless humidifiers are discussed in the “Buying Guide” given later in the article. To make your job easier, we have listed the best filterless humidifiers with notable features, pros, and cons. Check them out to make the best choice.

Things to Consider When Buying a Filterless Humidifiers
There are several benefits of choosing a filterless humidifier but still you need to consider various things to choose your perfect humidifier. We have listed some of the basic factors that will help to make the choice easier. Read them all carefully before investing in the filterless humidifier.
1. Tank Capacity
This factor will decide the time your humidifier will work without needing to refill it. The tank capacity is the first factor that will allow you to use the humidifier peacefully without the hassle of refilling it. Both the large capacity and the small capacity tanks have their individual benefits and drawbacks. The large capacity tanks are suitable for the ones who need the humidifiers to run for a longer period in time, more suitable for regular home usage. While the small tank humidifiers are suitable for office use where you need the humidifier to run for just a few hours.
2. Mist Output
The mist output is determined by the ability of the humidifier to produce the amount of mist in one hour. This factor will let the user know the effectiveness of the humidifier and if it is suitable for you. There are several brands and models which specify the maximum and minimum mist output, which also depends on the settings of the humidifier as well. For the maximum output, the settings need to be adjusted to the highest mist output settings. The average mist output is around eight ounces in one hour. Make sure that you choose a humidifier that has a mist output of not less than seven ounces per hour as the product will not be as effective as you want it to be.
3. Auto Shutoff
This is an important factor as the filterless humidifiers are smaller in tank size as compared to the whole house humidifiers. Therefore, the water in the tank needs to be refilled earlier as it runs dry quickly. So, the auto-shutoff feature is a good consideration as it enables the humidifier to turn off when it is no longer required. This, in turn, helps to prevent overheating and unnecessary power consumption. This also saves it from being a fire hazard.
4. 360-Degree Nozzle
As filterless humidifiers are not sufficient as whole-house humidifiers; this factor becomes important when you are looking at direct mist production in some specific position. It is better to go for humidifiers with this feature as it would provide a better user experience. You would find yourself using this feature more than you plan to.
5. Maintenance
Cleanliness is the key when it comes to maintaining the filterless humidifier. As there is an absence of the filter, germs and bacteria can accumulate and pollute the tube and the tank. So, most of these humidifiers come with instructions as to how to clean them. However, cleaning these humidifiers is easier said than done. So, look at humidifiers with a broader opening, so it is easier to reach the insides of the product.
