These devices increase the air’s moisture levels while keeping it clean through the use of advanced technology for cleaning.

  • Room Capacity – You should consider the size of the room that the specific models will handle. Think about the room’s current size that you want it to be placed in, and then think about if the model you are looking at can handle that. You want a machine that will be recommended for the room capacity so it will be efficient.
  • Water tank capacity – Another thing that you need to think about is the water tank’s capacity. This is important since you should consider how often it will need to be refilled, along with how long it will be able to operate. You also need to think about the maintenance required for the water tanks and how often you would need to undertake it.
  • Humidistat – This is another important piece of the machine, which maintains the current moisture level. This will tell the device what point it shouldn’t pass since you will customize this. Make sure that you choose one with this since it can determine the moisture levels in the air.
  • Sound level – The final factor you need to think about is the noise level since almost every model will have some noise. If you are using these in your office or bedroom, you want to choose a model that won’t be overly loud while you are sleeping.

These are only a few of the top tips that you should make sure you are considering when you are picking a model. The more you know, then the easier it will be for you to make the right decision.

Types of Filterless Humidifiers

There are plenty of types of humidifiers that you need to be aware of, and they come in 2 types, including warm and cool mist models. Here is what you need to know about these types, including:

  • Warm mist – These models should be operated carefully, especially when there are children around. This is because the warm mist models use the water to be boiled before it is placed into the machine. This would then create hot or warm steam, which could cause burns if touched. This is a great option if you want a warm mist, but not if you have children who like to touch everything.
  • Cool mist – These are the opposite of warm steam, and they don’t require warm or boiling water in the tank. You would be able to put any water into the tank, but it is recommended that you use distilled water. These would create a mist out of the water that would then be pushed into the air, which increases the humidity levels.

Ensure that you are looking at all of these models and what is available to make the final decision. If you are aware of the available types, you can figure out and see which one fits your needs the best.


  • What do I need to do to clean the humidifier?

Keeping your device clean needs to be a top priority since you want to have healthy and clean air. You should ensure that you have white vinegar on the handle along with running water and then disassemble the machine. Wipe the outside down with some water, which includes the filter-based area.

The tank also needs to be cleaned at least 1 time every month if you regularly use it. Pour a small amount of white vinegar into the tank so the bottom and corners are covered, and then let sit for around 30 minutes. If there are parts that have build-up, you can wipe them down with a cloth before letting the entire tank dry before usage.

  • Can I leave the humidifier running all night?

It will be extremely safe to leave these running overnight, especially if you pick one with an automatic shut-off feature. This would turn the machine off if there is a low level of water or overheating. Ensure that you are placing it in a location where it won’t create damage due to the mist or tip over during the night.

  • Can I use some tap water in the machine?

You should never use tap water in these devices, but instead, you want to use distilled water. The tap water can be challenging and have debris and build-up already in it that can cause problems. If you don’t use distilled water, then you might end up damaging the device when it is being used.

  • Where is the best location to put my machine?

If you are uncertain about where to put it, you should place it in a central location. Ensure that wherever you are putting it, it isn’t on top of wood since it can wrap it. Also, make sure not to place it on carpet or any other fabric, but instead put it on a plastic stool or even on a side table. You also need to ensure that the area you choose is sturdy and won’t tip over easily, which could cause a big mess if the tank is opened or spilled.


Make sure that you are thinking long and hard about which filterless humidifier you will choose, especially if you haven’t bought one of these machines before. You should ensure that you determine what room capacity the various models can handle and what the water tank capacity is. Also, make sure that you pick one that will operate quietly when it is on and that would be easy to clean and even refill when the water tank is empty.
