Interestingly enough, there are several reasons as to why a significant number of people are opting for the best filterless humidifier. One known reason is cost. You see, standard humidifiers require constant filter replacements. These filters are not particularly cheap, especially among selected brands.
A filterless humidifier also removes the need for changing filters frequently, which, in turn, enhances the convenience of their users. But certainly, the ability of these filterless models to clean and improve the quality of your indoor air should never be underestimated.

As a top-fill humidifier, expect that you will not have any trouble in refilling it. You simply have to pour the water on top. However, I do have to remind you that the inlet is small.

How To Choose The Best Filterless Humidifier
When the time comes that you want a filterless humidifier, you have to make sure that you know how to pick one. Of course, you would really want the humidifier to function the same way as the standard ones.
Either way, your main goal here remains the same: regulate the indoor humidity of your space. Always remember that the primary job of a humidifier is to induce moisture in the air to prevent it from drying. We all know that little or excessive humidity is not suitable for human health. Drying, for instance, can cause irritations in the eyes and skin.
Many people forget that humidifiers are not the same as air purifiers. The latter is designed to cleanse your indoor air from the unwanted pollutants and allergens. Hence, it is not a big deal if the humidifier does not have a filter. After all, it is not its primary function.
It is quite justified if the humidifier should not come without a filter. It is not really that integral. However, I can say that it is useful in helping the air to be clean. But just like I said, it is not that crucial.
When you choose a filterless humidifier, you have a guarantee that it can do its job. And for that, these are the following indicators that you should consider.
Mist Output
The quality of a humidifier is based on how it sprays. Generally, you don’t want the humidifier to spray randomly. It should be accurate, encompassing, and comprehensive. You should check if the nozzle of the humidifier is rotating and spreads upward. Such a design would allow the humidifier to moisturize an entire room or space.
Furthermore, you should check if the humidifier is spraying mist, not droplets of water. The mist must be tiny and fine so that it can be absorbed by your indoor air; otherwise, it is just water that is being sprinkled all over the place. You don’t want to wake up seeing your floor and home items wet and muddy.
Humidistat
I know that not all humidifiers have a humidistat. But for me, this one is an integral part that puts a humidifier in a better position in keeping the humidity of your room correct. A humidistat is basically a gauge that measures the current room humidity. Once it detects the humidity, it will be able to adjust the output of the humidifier.
Always remember that the appropriate humidity level in a room should be around 40% to 60%. It would really be great if the humidifier can measure this for you. It is difficult to assess things based on your instinct. Most of the time, it is not accurate.
Tank Capacity
Next, you need to consider the size of the water tank of a humidifier. Given that you have a large room, it is not cost-efficient to invest in tabletop models. Their reach is limited, and they don’t have enough capacity to ensure that the entire space is humidified. The right choice here is to get a humidifier with a large tank and strong mist output.
But if you are planning to humidify only a specific room of your property, such as your bedroom, there’s no need to get these large and burly humidifiers. You can settle with their compact counterparts. They have small water tanks, but they are sufficient enough to cover restricted room sizes.
Noise Level
Of course, you should not ignore this one. A humidifier should be a friendly home appliance. It should never cause a disturbance in your home. If it does, then it is not a good addition. Noise is not a part of the deal that you want to take. While it is true that these humidifiers do produce sound, it should not be on the level that it disturbs or distracts people.
For me, the acceptable noise level for these humidifiers should be around 20 decibels to 30 decibels. They should not be any louder than this.
