How To Clean And Maintain Your Humidifier

Humidifiers are the best way to provide moisture to the dry indoor air. The article provides a comprehensive guide about cleaning and maintaining humidifiers.

Nobody wants to live in a home choked with dry and dusty air. Running a humidifier is by far the best way to add moisture to the dry indoor air, especially in winter. However, dirty humidifiers can do more harm than good and create a dangerous environment.

Uncleaned humidifiers can omit harmful particles in the air causing several respiratory problems. Cleaning your humidifier regularly will decrease the presence of these particles in the air, thus decreasing the chances of you inhaling dirty air.

The article below explains everything about how you can clean and maintain your humidifier and when to replace it.

Why Should You Clean Your Humidifier?

Humidifiers are responsible for releasing moisture into the air. Along with moisture, other elements such as;





These particles are invisible to the naked eye or perhaps settle as white dust in your room.

However, breathing in these particles can cause irritation and soreness in the lungs. Individuals with allergies, asthma, or other breathing diseases are especially prone to be affected by the unwanted particles in the air.

People without any such conditions can also develop harmful symptoms (flu-like or other breathing problems) by inhaling dirty humidifier air.

Humidifier Basics

Humidifiers have a tank or a reservoir that you can fill with water. The other parts of the machines that help pump moisture in the air are:

Rotating disk




In addition to having the same basic components, there are several types of humidifiers fit for various functions:

Central Humidifiers: as the name indicates, they are installed to humidify your whole home.

Cool Mist Humidifiers: impeller and ultrasonic humidifiers emit cool mist.

Warm Mist Humidifiers: like warm water humidifiers, they first heat the water and then release the warm mist in the air.

Evaporators: these are portable and inexpensive humidifiers. They blow air on the water from the fan that is released through a wick, belt, or filter.

How To Clean A Humidifier

There are several ways you can keep your humidifier clean. As a general rule, you should rinse and dry out your humidifier every day and carry a more deep cleaning once a week. Remember to unplug your machine before cleaning.

Following are some tips to get your humidifier clean safely

Wash And Dry Humidifier After Each Use

Empty the water tank or reservoir between each use. Clean the tank with water and soap after. Dry the basin every time you replace the water. Remember to keep your machine unplugged during the whole process.

Read The Manufacturer's Instructions

Before proceeding to deep clean your humidifier, first consult the manufacturer’s instructions to get the process correct. This will give you proper guidance on how to clean your humidifier and which parts need to be cleaned or replaced.

Moreover, if you have a permanently installed humidifier, a professional humidifier repair and maintenance company will need a biannual service.

Use The Right Cleaning Products And Tools

You can use water, vinegar, hydrogen peroxide, and other manufacturer-recommended cleaning materials to clean your humidifier. This will clear out any potential toxins from your machine.

According to the environment and natural resources department, using 2% hydrogen peroxide for efficient cleaning is beneficial. Use a scrubbing brush to clean small areas of the machine to ensure that the whole device is cleaned thoroughly. Watch out for scales or any other build-up, and make sure to clear away all of it.

Moreover, if you are using the cleaning solution, then remember to rinse the machine thoroughly.

Replace The Filter

Some humidifier parts need to be replaced regularly. Central humidifiers and evaporators have filters that need regular replacements. At least every quarter or even more frequently in high activity times.

You can find the optimum number of filter replacements in your manufacturer’s manual. It is better to buy a few additional filters to have them on hand in case of an emergency.

Use Fresh Distilled Water For Every Use

Distilled water is free of minerals and other materials that can cause build-ups in various parts of the humidifier and release particles into the air.

Keep The Area Around The Humidifier Dry

You can avoid mold formation and other build-ups in the machine by keeping the surrounding area as dry as possible. Check upholstered furniture, windows, rugs, and carpets for moisture. If you find the area damp around the machine, turn off the humidifier immediately.

Clean It Before And After Storing

Make sure to deeply clean and dry the machine thoroughly before storing it for any length of time. Dispose of the replaceable parts like filters. Store the device in a dry place. Repeat the cleaning and drying process before using it again.


Cleaning and drying the humidifier each time you use the humidifier is the best way to maintain the machine. Even though cleaning can increase the lifespan of the machine, some parts still can’t be reached and become unhealthy over time. Therefore, it is better to replace your old humidifiers.
