What Is The Difference Between Air Purifiers And Humidifiers?

Air purifiers and humidifiers affect the air you breathe in your house, but they each have different benefits. Suppose you want to treat allergies, respiratory issues, and dry air or build a healthy home for your infant. In that case, you need to know the differences between an air purifier and a humidifier and how to use them. We will explain how each device works, how to operate it safely, and when to use an air or humidifier.

Air purifier vs humidifier: which one should you get?

Air purifiers and humidifiers sometimes need to be corrected. Yet, each machine handles distinct challenges. Portable air purifiers are designed to eliminate allergens, pollutants, mold, and odors from the air. Adults and children who battle allergies and asthma may benefit from this. The two fundamental components of an air purifier are a fan and a filter surface. However, the specific filtration technology might range from conventional HEPA filters to ionizers to brand-new technologies.

Choose an air purifier to:

  • Reduce pet dander and allergens.

  • Reduce the tendency for indoor dust particles to accumulate.

  • Remove scents from cooking, dogs, and mold from the home.

  • Avoid adverse responses caused by severe respiratory disorders such as asthma.

Therefore, does a humidifier clean up the air? No. Their function neither improves air quality nor decreases airborne pollutants. Humidifiers, conversely, are machines that emit water vapor or steam into the air to enhance humidity levels in a room or the entire house. Depending on the type of humidifier, it may generate either hot or cold water vapor.

Congestion-stricken adults and children can benefit from a room's increased humidity. In addition, higher humidity levels may alleviate dry, cracked skin and nasal passages caused by the winter air's lack of moisture.

Forced-air heating, ventilation, and air conditioning (HVAC) systems may drastically dry out the air in your home, making humidifiers a need. Yet, when it is extremely cold or hot outside, HVAC systems recycle significantly more inside air because they cannot quickly heat or cool enough outdoor air. HEPA air purifiers are essential for removing dust, allergies, and pathogens without fresh air.

Choose a humidifier to:

  • Combat arid, dry environments.

  • Raise the level of moisture in a home.

  • Decrease respiratory difficulties such as nosebleeds and sinus pressure caused by dry air.

  • Provide relief for dry, itchy skin and other skin disorders, such as eczema.

Air purifier vs humidifier: which works better for different conditions?

For babies

Air purifiers and humidifiers may be beneficial for your infant. But, leaving a humidifier on continuously is not advised. Condensation on floors, walls, and other surfaces can be caused by excess moisture in the air, making your home more susceptible to mold, dust mites, and bacteria. A buildup of these microorganisms may cause an allergy, asthmatic flare-up, or respiratory symptoms in adults, children, and infants.

Use a hygrometer if you are concerned that your home has excessive moisture. This gadget measures the relative humidity and temperature of a given space. In general, indoor humidity levels above 60 percent are considered high.

If your infant has chest and nasal congestion, a humidifier may assist in alleviating their discomfort.

Note: if your babies are sleeping, we recommend our quiet or mini air purifiers.

For allergens

An air purifier can aid in reducing allergy concentrations in the air. This technique goes beyond only trapping particles by eliminating allergies in the air. Even though humidifiers may alleviate a stuffy nose or other irritations, they can exacerbate allergies since higher humidity increases dust mite survivability.

For asthma

A humidifier helps alleviate asthma symptoms if dry air is also an issue, but it does not affect asthma itself. Higher indoor humidity levels are linked to asthma attacks because they can stimulate the growth of dangerous bacteria, dust mites, and mold. As air contaminants frequently trigger asthma attacks, an air purifier that can eliminate these particles is preferable.

Can both an air purifier and a humidifier be used?

Both an air purifier and a humidifier can be utilized together. Although the air purifier removes allergens, the humidifier adds moisture to the atmosphere. For people with respiratory problems, this provides the utmost ease of breathing. 

Remember that each gadget should be put separately, preferably at opposing ends of the room. Otherwise, the humidifier's moisture could block the air purifier's filter, leading to mildew and bacteria growth.


Do air purifiers dry out the air?

Hence, the answer to whether air purifiers dry the air is no. Air purifiers cannot reduce indoor humidity but only enhance air quality. When cleaning the air and improving air quality, an air purifier will not affect the relative humidity.

Do you sleep better with a cleaner in the room?

Will a purifier improve my sleep? A clinical trial in May 2019 indicated that only altering the air quality significantly improved participants' sleep. Air purifiers eliminate airborne particles. These cleaning gadgets alleviate allergy symptoms and enhance the quality of sleep.

Should you operate a humidifier during the day or only at night?

Keeping your humidifier on overnight positively affects your health and well-being. You'll have far better sleep, reduced risk of infection, and hydrated skin. A better night's sleep: When your humidifier is on while you sleep, it maintains the humidity in the room.

Should I operate my air purifier 24 hours a day?

Indeed, it would help if you operated your air purifier around the clock and never turned it off. You should never turn off your air purifier, even when you are asleep or away from home.

Have air purifiers had any adverse effects?

In addition to an increased risk of respiratory infections, potential side effects include throat discomfort, coughing, chest pain, and shortness of breath. Some ozone air purifiers also have an ion generator, sometimes an ionizer. Ionizers are also available as standalone units.


So, what is the difference between air purifiers and humidifiers? We provided the answers and usages of them in this article. We hope this will be helpful for you in choosing your personal air purifier and humidifier.
