Filter-Free Humidifier VS Filtered Humidifier: Pros and Cons

Sharing is caring!

Have you noticed that the air in your house is dry and almost scratchy in your throat when you breathe? If so, the humidity levels in your house may be out of wack with a drop in the amount of humidity in the air.

Most home renovation experts and trusted healthcare professionals recommend that the air in your home contains around 50% relative humidity level. That is the amount of moisture in each particle of the air throughout your home.

While too much moisture in the house can cause serious health and even structural issues, it is important to note that not enough moisture can do the same. The proper levels of moisture in a home can reduce allergy and cold symptoms, as well as reduce dry skin or flare-ups of common skin conditions.

Dry air can also affect the wood and other materials that were used in the construction of your residence. With too much dryness in the air, the wooden support beams and furniture can also dry out, leading to cracks or splits and a loss of strength. It becomes


brittle and easily snapped when pressure is applied. Fire hazards are also increased because of the dry nature of the wood and linens.

There is an appliance that can help balance the levels of humidity in your home and that is a humidifier. With multiple types to choose from and different unique features associated with each one, it can become overwhelming when deciding. Not only are there different types but there are different styles within that particular type. The most notable difference is the use of a filter during operation. How can a filter help? What does it do? Is it more advantageous to have a filter? Let’s find out together.

What is a Humidifier?

Simply put, a humidifier is an appliance that is used to adjust the level of moisture in the air of your home. The reasons for wanting to adjust the moisture levels could be physical, structural, or a combination of both.

Most humidifiers emit moisture into the air by the use of a fan and motor powered by electricity or batteries to dispel particles of water into the atmosphere. You can purchase cool mist humidifiers, warm mist humidifiers, or even sonic vibration humidifiers. They can be a single unit (portable to each room with an electrical outlet) or big units that are installed directly into the central air system of a home.

Unfiltered Humidifiers

An unfiltered humidifier is a humidifier that doesn’t come with a filter but instead just passes water through its operating system to the air. It generally comes with a built-in purifying system, removing bacteria and allergens from the moisture before releasing it into the air.


Avoid maintenance on the filter

A humidifier, like any appliance, requires some maintenance from its owner. You have to clean the parts of the machine in which the water is stored, the components that omit the water, and the vents from which the water enters the air.

The filter in a humidifier should be cleaned each week, especially if you use it daily. Special cleaning solutions may be required to avoid compromising the fibers of the filter.


Avoid the cost of a replacement filter

Some humidifiers may require a replacement filter every one to two months. This can become costly and frustrating, especially if you use your humidifier on a daily basis. Installation of the filter sometimes falls to the owner (even some central air units), which can be cumbersome for some who live a busy lifestyle and may not always be around to change the filter on time.

Risk of bacteria and allergens entering the air

The main purpose of a filter is to remove harmful bacteria and allergens that can develop in dark, damp areas. Without a filter, there is a greater risk of bacteria that can cause long-term health problems living in the air you and your family breathe on a daily basis. If you already live with respiratory problems, the use of an unfiltered humidifier can increase symptoms instead of reducing them.

Will require more vigorous maintenance on other operating parts

Most humidifiers that come without a filter have other systems in place that reduce the number of bacteria and allergens that enter the air. This means that additional maintenance and cleaning on the unit is required. Cleaning instructions should come with your unit so that you can perform preventive maintenance right at home. Special disinfectants may have to be purchased or a cleaning solution made especially for your humidifier.

A filtered humidifier is a humidifier that omits moisture into the air but only after it has passed through a filter to remove any harmful bacteria, mites, or allergens. This style of humidifier can be considered healthier, but it can also be slightly noisier, according to consumer complaints.


Removes bacteria and allergens from the moisture particles before sending them into the atmosphere

If you currently live with respiratory issues, such as asthma, or skin conditions such as eczema, you know that certain bacteria or allergens can bring on an attack or increase in symptoms. The use of a filter reduces the amount of these nasty critters from entering the atmosphere. They will help you get the most out of your humidifier, instead of leaving you regretting your purchase.


Those who live a healthy lifestyle find peace of mind in the knowledge that the moisture and air in the home are the cleanest it can be, regardless of the appliances being used.


Can be costly when a filter replacement is needed

When a replacement filter is required every one or two months, it can become irritating and costly. The irritation factor is the purchasing of the filter, changing the filter, and the disposal of the filter. The cost factor is the actual price of the filter. Depending on the brand, unit, and style, the filters could cost up to $20.00 each time.


Noisier than an unfiltered humidifier

Some consumers reported that a filtered humidifier is louder than an unfiltered one. Low-end units can omit gurgling noises or wheezing as the moisture passes through the filter.
