How to choose the best brand and model

The most important thing to consider is that even though you don’t have to worry about buying and instaling a filter, you need to clean a no filter humidifier more often than if it had one.

The point of a filter is to keep the water and vapor as clean and germ-free as possible. The filter collects all the particles that can lead to bacteria and mold growth inside the unit. A filterless humidifier means that you don’t get this extra protection from allergens.

Does this mean you shouldn’t buy a filterless humidifier? No, it just means you need to take extra care when using one. Clean your filterless humidifier at least once per week, and use filtered water if you have access to it.

Before making your choice, know the approximate size of the room you want to use the humidifier in. This helps you work out the coverage area you need.

Will you be using the humidifier in a bedroom or in a living space or in the whole house? If it’s for a bedroom, you can get away with using a type of humidifier with a smaller water tank capacity.

If it’s for a living room,  a larger water tank capacity is best.

Finally don’t forget to consider the pros and cons of each humidifier model before making your choice.

Now let’s check out our best humidifier without filter reviews!

Frequently Asked Questions

What’s the difference between a humidifier with a filter, and a humidifier without a filter?

The main difference between a humidifier with a filter and a humidifier without a filter is the ongoing cost. A humidifier without a filter means you don’t have the ongoing cost of replacing filters. But you will usually pay more to purchase a humidifier without a filter than one with a filter.

While not having a filter in your humidifier will save you money in the long run, you need to ensure that you clean your humidifier on a regular basis.  This is one of the cons of using a humidifier without a filter. It is recommended that you change the water inside the humidifier each day.

Once a week you should clean the unit using vinegar, to remove any potential mold, germs or dust.

Humidifiers with filters do not have to be cleaned as often as those without filters.

Another difference is that humidifiers without filters tend to disperse more dust and other contaminants into the air. This is because there is no filter within the humidifier to filter the contaminants before they are dispersed.

As discussed in our post HERE, our water contains many different particles and contaminants. One way to remove these is to filter your drinking water. If you do not use a filter for your drinking water, then the water that you put into your humidifier will contain these particles. In a humidifier without a filter, they will be dispersed into the air. Sometimes this results in a white dust from the mineral deposits found in the water.

This will not be an issue if you already use a water filter that can filter out minerals and other fine particles. If you are interested in finding out more about water filters or want to purchase one, you can do so via THIS LINK.

One final difference between a humidifier with a filter and a humidifier without a filter is the operation noise. Most humidifiers with filters use a fan within them to cool the water down, and so are noisier than those without. Most humidifiers without filters do not have this fan, and so are quieter.

Can I use a filterless humidifier?

Yes you can, as long as the humidifier is one that’s made to be used without a filter. Not all humidifiers should be used without a filter. Most of the best filterless humidifiers are cool mist humidifiers, because the warm mist type create more allergens, mold and bacteria hence why they’re better used with a filter.

Do I need a filter for a humidifier?

Most humidifiers use a filter, but if you buy one of the humidifiers recommended in this post, you can use the humidifier without a filter. When shopping for the best filterless humidifiers, look at the features of each model before choosing the right one for your home.

Which brand of filterless humidifier is the best?

This depends on a number of factors including the room size, your budget and the features you want. Most have an auto shut off feature, and many have a low or high speed function.

Do cool mist humidifiers need filters?

No, most cool mist humidifiers don’t need filters. The cool mist humidifiers recommended in this post don’t use filters. You need to check each model to see if it requires a filter or not. Make sure you do your research on cool mist humidifiers.

Do you need to use a filterless humidifier in the summer?

This depends on where you live- if you live in a dry climate with very hot, dry summers with little moisture in the air, you may want to use a humidifier in the summer. Humidifiers add moisture to the air and if the air in your home is very dry in the summer, you might want to use one. Humidifiers are also great for helping with asthma and allergy symptoms in the summertime.

Is it good to use a filterless humidifier in the summer?

Yes, you can sleep with the best filterless humidifier still running all night. If you want to buy a humidifier that can operate all night, make sure you choose one that has a high enough water capacity to be able to operate for longer hours.

Do filterless cool mist humidifiers make the room cold?

Generally speaking, cool mist humidifiers don’t make the room cold. The amount of mist output that is dispersed isn’t enough to make a room cold. However, some people prefer using a warm mist humidifier instead. In this article we have reviewed the best filterless humidifiers that are cold mist and warm mist so you can choose the one you prefer.

How do I clean my filterless humidifier?

You can use warm soapy water to wipe down your humidifier and also to rinse out the water tank and wipe down any dust. Vinegar is also a great natural ingredient to use when cleaning out your humidifier. Make sure your unit is unplugged from the electrical socket before cleaning, and do NOT immerse in water. Follow instructions in the manual you receive from your humidifier’s manufacturer.

A Humidifier With A Filter Or A Humidifier Without A Filter: Which Is Better?

Let’s look at the pros and cons of both a humidifier with and without a filter.

The best humidifier with a filter is better for those with respiratory problems who do not use a water filter in their home. This is because the mold, bacteria, germs and dust is filtered out before the mist is dispersed. This is not an issue if you already use a water filter in your home.

The best filterless humidifier is better suited to those who prefer a quiet operation, such as when it is being used in a baby’s nursery or a child’s bedroom. It is also better suited to those who do not want to pay the ongoing costs associated with replacing filters. The negative aspects of having the best filterless humidifiers can be eliminated by using a water filter in your home.
