Best Filterless Humidifier Buying Guide – Top Reviews 2018

A humidifier is a valuable household device as it helps to moisturize and clean the air. It is important for babies and individuals with respiratory issues like sinus problems and asthma. But, like any other device there are many types of humidifiers out there, and so you will need to know them to make the right pick.

One of the important decisions that you will need to make is whether to go for units with filters or the filterless ones. Although both are useful in humidifying the air, they are suitable for different situation or users. And so it is important to understand the difference between the two to make the right pick. More and more people nowadays seem to prefer the filterless units. However, it is still important to know how to choose the best filterless humidifier from the many types and brands on the market.

Top 4 Filterless Humidifiers On The Market

​Filter VS Filterless Humidifier

Although these units might look the same on the outside, there are some clear differences between the two. The main difference is the fact that one has a filter while the other does not use one. Also, the mechanism or how they work is different. The units with a filter will work by boiling and drawing water through the filter to a fan that then expels it in the form of a mist to humidify the air.

Unlike the filter humidifiers, the filterless ones will use an electrostatic charge to remove impurities from the air. These units also produce less noise, and they will require minimal maintenance and cleaning. You will also never need to change the filter which means that they are cheap to own since you do not need to buy anything else in future.

​Factors To Consider When Shopping For Filterless Humidifiers

Almost all companies that make humidifiers will have a filterless model. And so you can always be sure of getting many options when shopping for one. But, to ensure that you get the best filterless humidifier you should consider the following factors before making your pick.

Best Filterless Humidifier


​The size will determine the area that the humidifier can humidify. And so it should always be one of your first considerations. Your house/room size should guide you when it comes to choosing the right capacity. It is always vital to make sure that you go for a unit that produces enough mist. Also, ensure that you do not go for one that is too large because it will be energy inefficient and can also create too much moisture and encourage the growth of mold.

Ease Of Cleaning​

Although the filterless humidifiers do not have a filter, they will still need regular cleaning and maintenance. The impurities from the water and air will accumulate in these units and affect their efficiency, and so you need to clean them regularly. A good one should make this easy, and you should be able to take it apart and assemble it quickly. Also, the best ones are those that will not require you to clean them daily.


​The more the control that the best humidifier offers the better it will be for you and your baby. A unit that lets you control the moisture level with variable fan speeds makes it possible to adjust the moisture level according to the season or time of the day. Also, those with a timer and auto shut off feature will offer you better control.


​A humidistat is an essential element of any humidifier since it prevents the humidity level from going beyond a certain point. You should make sure that you always go for a humidifier with one because those without one can produce excessive amounts of moisture which is also not good for your health. If your filterless humidifier does not come with a humidistat, you should consider investing in a separate hygrometer.
