What is the Difference Between an Air Purifier and an Air Humidifier?

|Jan 18, 2022

Contemplating between an air purifier vs. humidifier?  An air purifier is confused with an air humidifier most of the time.  Having some fresh air to breathe becomes critical for folks who have allergies and can't stand dust mites, pollen, and other harmful allergens.  Folks with allergies have it tough, from runny noses to watery eyes, itchy throats, to blocked noses.

The answer is a good-quality air purifier.  However, when you start searching, air purifiers are mixed with an air humidifier.  The differences between humidifier and air purifier start with the purpose of the appliance.  An air purifier benefits you by cleaning the indoor air of your rooms by removing air pollutants like dust, smoke, pollen and more.

On the other hand, an air humidifier makes the indoor dry air moist by adding moisture.  They are of two types, hot or cold mist spray machines.  Humidifiers are usually used when the air moisture falls below twenty to thirty percent.  An average room requires above fifty percent humidity levels, without which the skin starts to feel dry.  Healthline reports that dry air can cause irritation to your eyes, worsen the symptoms of asthmatic patients, increase your stress levels, cause nosebleeds or more.  Research shows the need for cold and dry air for those with dry cough symptoms.

The United States Environmental Protection Agency recommends a moisture level of at least 30 to 50 percent inside your home.

Now stop thinking about air purifier vs. humidifier, and get yourself one of the quietest air purifier from our recommendations below.

Difference Between Humidifier and Air Purifier

Difference Between Humidifier and Air Purifier

Air purifiers vs. humidifiers are some of the most common appliances in homes and offices. Both are excellent options to improve indoor air quality. Still, it can be tricky to choose between both options since they're similar but also provide different things, making them useful for different people in specific situations.

Both of these devices can be helpful for people who struggle with breathing or sinus issues. However, the difference between an air purifier and humidifier comes down to how they offer relief to the user.

We will now explore the similarities and differences between an air purifier and a humidifier. This way, it’ll be easier for you to choose one over the other based on your needs. Is an air purifier the same as a humidifier?  You can also learn more about dehumidifiers vs. air purifiers.

Air Purifier: What is it for?

Air Purifier: What is it for?

As its name suggests, an air purifier eliminates all the airborne contaminants that are present in the room. The list includes allergens and dust particles but doesn't leave behind bacteria, and mold spores, among many other particles that could worsen the indoor air quality.

Once your air purifier starts working, it will suck the air in your home into the machine and then will pass it through several filters to clean all the potentially harmful particles. The filters can vary depending on the model.

So, given this information, between air purifier vs. humidifier, an air purifier can be helpful for people with allergies, asthmatics, and those who want cleaner air at home.

Humidifier: What is it for?

Humidifier: What is it for?

Next up, we have humidifiers, which put moisture back into the air within the area. The humidifier pumps water vapor into the air, and sometimes it is visible; sometimes it is not. It depends on the model. Hence, it has the exact opposite function as a dehumidifier.

Humidifiers need water to function. Therefore, once it runs out of water, you’ll need to replenish it for it to be able to function properly.

Does a humidifier help with dust? These devices can be helpful for people who struggle with irritated respiratory tracts or those who would like to soothe dry skin. It is also helpful for those who struggle with nosebleeds and asthma. However, they are not recommendable in places where the humidity is already high, as it may encourage mold growth. It’s often advised to keep the humidity levels in your house around 30-50 percent.

So, which one should you choose?

Both devices can coexist together. However, if you aim to add only one of them to your home, here's what you should consider:

  • If you or someone you live with has asthma, allergies, or any breathing issue that's caused by polluted air, perhaps an air purifier is a better option. This device can also be helpful if you live with animals and would like to reduce the pet dander and allergens present in your home. Overall, these devices can contribute to keeping your house cleaner.
  • On the other hand, it’s highly recommended to choose a humidifier if you live in a dry or arid climate and would like to improve the moisture levels at home or at the office. It can also be helpful for those with sinuses problems, skin, hair, or eye dryness, as well as those who tend to snore while sleeping.

As you can see, the air Purifier vs. humidifier comes down to what you're looking forward to. Hence, we highly recommend evaluating the problems you're having at the moment so you can be sure of which option could work better for you.
