what is the difference between humidifier and air purifier

what is the difference between humidifier and air purifier? When it comes to improving the air quality in your home, air purifiers and humidifiers have their benefits. However, it is important to remember that they are not the same and have completely different uses and properties.

The air purifier is designed to produce clean and healthy air by removing or deactivating gaseous and polluting particles from the air. Air cleaners usually consist of a motor, a fan, and an air filter. The motor and fan are used to circulate the air, while the filter is used to remove contaminants from the air circulating in the machine.

Many types of air filters are available, from mechanical HEPA (High-Efficiency Particulate Filters) filters to ionizing filters. They all have different strengths and uses. So it pays to do your research to make sure you’re buying the right type for your needs. What

air purifiers have in common is that they direct air through the unit and remove or trap contaminants such as dust, dust mites, pollen, and mold spores through the filter media, creating a flow of fresh air. Air filters do not add moisture to the air during this process.

The humidifier adds water to the air. This can be done in a number of ways, such as boiling water into steam, vibrating water droplets in the air using ultrasonic technology, or using fan and wick evaporative humidifiers. It should be noted that ultrasonic humidifiers combined with tap water can introduce fine mineral particles into the air.

There is currently little research into the effects of these particles, but some research suggests that they may affect lung tissue. Since humidifiers are not designed to purify the air, they are best used with distilled water and a regular cleaning schedule, or in conjunction with an air purifier, which filters the air and removes dust and other fine particles and impurities from the air.

When purchasing an air purifier, consider the size of the room and the noise level it produces.

You must also specify the type of filter you want. The most common type of filter is the mechanical filter, which retains particles in the air.

What is a humidifier?

A humidifier is a device that increases the humidity in a room. This is beneficial in dry or cold climates when there is a lack of moisture in the air.

Humidifiers come in many shapes and sizes, but all add water vapor to the atmosphere. In the United States, humidifiers are used in New York City and other areas with cold winters.

Consumers can purchase humidifiers at most home improvement or online retailers. Depending on the size and equipment, their price ranges from around 30 to 400 US dollars.

Before purchasing a humidifier, consider the needs of the room or space in which it will be used.

Key Differences Between Air Purifiers and Humidifiers

While air purifiers and humidifiers contribute to a healthier indoor climate, they have different functions and meet different needs. Understanding the key differences between these devices will help you determine which device best suits your specific needs. Here are the key differentiators:


The primary purpose of an air purifier is to remove pollutants and contaminants from the air, thereby improving overall air quality. A humidifier, on the other hand, adds moisture to the air, increasing the humidity level to alleviate dryness in the area.


Air purifiers draw in air and pass it through filters that trap and remove particles and pollutants. They focus on removing allergens, dust, pet dander, smoke, and other harmful particles from the air. Humidifiers, on the other hand, emit water vapor or mist to increase humidity, relieve symptoms of dry air, and improve respiratory health.

Air Quality Impact

Air purifiers are designed to remove pollutants from the air and improve air quality by reducing allergens, odors, and volatile organic compounds (VOCs). While humidifiers can help alleviate the discomfort of dry air, they have no direct impact on air quality or the removal of pollutants.

Respiratory Health

Air purifiers are helpful for people with respiratory problems like asthma or allergies as they help remove allergens and irritants from the air, relieve symptoms, and improve breathing. On the other hand, humidifiers relieve symptoms of dry air such as congestion, dry throat, and skin irritation.

Recommendations for use

Air purifiers are generally recommended for people who are sensitive to indoor air quality or who suffer from allergies or respiratory diseases. Humidifiers are recommended for people who experience dry air symptoms, especially in dry weather or in areas with low humidity.
In general, the main difference between air purifiers and humidifiers is their purpose and function. Air purifiers focus on removing pollutants and improving air quality, while humidifiers add moisture to the air to relieve dryness and its associated symptoms. Based on your specific needs and room conditions, you can decide whether an air purifier or humidifier is right for you.

How do they work?

air purifiers have different types of filters inside. Some even have different filter combinations including HEPA, ionizers, pre-filters, and activated carbon filters.

They remove small and large particles and absorb all unwanted smells and odors. They also have fans that can create airflow.

Most people assume that air pollution only occurs outside of their homes, but that’s not true: the indoor environment contains just as many pollutants as the air outside.

Also, indoor air can often be more polluted since many of us spend most of our time indoors.

For Kids

If you have young children, an air purifier can help protect them from pollutants that are too small for their lungs to filter naturally. It also keeps your home clean and comfortable by eliminating odors and other pollutants. Read our guide to the best air purifiers for kids’ rooms.

For Pets

If you have pets or smoke in your home, you need an air purifier to remove large particles like dust, dander, and smoke. Read our guide to the best pet air purifiers.


If you have asthma or allergies, you need an air purifier with a high CADR rating that can remove small particles like pollen, dust mites, and pet dander from the air. Read our guide to the best air purifiers for allergy sufferers.


Works by adding condensation to the air. Some humidifiers have a tank that needs to be filled with water, while others use a filter to absorb moisture from the environment. The water vapor then penetrates the room and increases the humidity.

Is it possible to over-humidify? Unfortunately yes! The surface moisture must be between 40% and 60%. If they exceed this range, condensation will form on surfaces such as walls or ceilings, causing water damage over time.
Is it possible to under-humidify? Yes, if you are using a humidifier that is not appropriate for the size of your home, it may not meet your needs.
