There are two types of appliances that can help you breathe easier in the winter: an air purifier and a humidifier. The decision between air purifier Vs humidifier can be difficult to make, especially when you are not familiar with how each of them works. Many factors count in the decision, including what you need in your home and how much money you want to spend. 

Air Purifier vs Humidifier

For example, if your goal is simply to lower allergens in your home and moisture is not a problem, then a humidifier may not be the best option for you. Similarly, if you have a dry throat or nose because of cold weather conditions, then a humidifier might just do the trick! 

The truth is that both air purifiers and humidifiers play important roles in creating an environment that is safe for your family. However, there are some differences between them. Understanding these differences will help you make a more informed decision when deciding which one best suits your needs.

What does an air purifier do?

An air purifier works as a filter, trapping and eliminating airborne contaminants that can cause allergies or other health problems. You should consider an air purifier if you are sensitive to allergens like pollen, dust mites, or pet dander.

Air Purifier

Air purifiers remove particles and allergens from the air. They do this by creating a negative pressure environment, which forces these toxins out of the home into the purifier filter or through an exhaust vent (for larger units). This is effective for people who suffer from allergies or asthma as well as pets that are prone to shedding hair and dander. 

What does a humidifier do?

Humidifiers are designed to add moisture back into the air in dry climates or when heating your home with a furnace. They work by taking water and converting it into steam which can be distributed throughout the room via an overhead fan as well as through cool misting nozzles that you can manually adjust. 


Humidifiers are great for people who have dry skin or suffer from allergies. It is also a great option for those who are prone to having a dry throat, nose, or sinuses. A humidifier can also help alleviate symptoms of coughs and colds when the air is dry. Also, it is perfect for those with asthma and other respiratory conditions as it helps to keep the nasal passages moist and clear.

What are some things to consider in choosing either or both?

Some things to keep in mind before purchasing an air purifier or humidifier include cost, size, and your health needs. For instance, if allergies are your main concern, then an air purifier may be a better option. If it’s dryness that is causing problems such as sinus congestion or coughing spells, then humidifiers can help alleviate those symptoms.

What are humidifier benefits?

The humidity level in your home can have a severe impact on how you feel. In winter, it’s necessary to keep the air moist so that dry indoor heating doesn’t cause too much static electricity or uncomfortable skin and eye irritations. 

  • Moisturizes dry skin and nose 
  • Reduces sinus infection risk by keeping nasal passages moist 
  • Helps relieve a sore throat
  • Reduces symptoms of asthma, bronchitis, and other respiratory diseases 
  • Improves quality of sleep by reducing dryness or congestion during nighttime breathing, thereby reducing snoring and dry mouth
  • Limits exposure to allergens 

What are air purifier benefits?

An air purifier removes allergens, pollutants, and irritants from the air, while a humidifier only increases humidity levels in your home by adding moisture to it. Air purifiers work well for people with a history of asthma or allergies because they cut down on those triggers that cause symptoms.

  • Removes airborne particles, allergens, bacteria, viruses from the air and reduces symptoms of allergies 
  • Kills germs on household surfaces such as tabletops or countertops 
  • Air purifiers also reduce the need to clean your home as often

It is important to note that there are some overlaps in the benefits of these two appliances. For instance, using a humidifier can help relieve some respiratory problems caused by allergens. Also, the right humidity level can protect you from viruses. According to some studies. The infectiousness of certain viruses is less powerful when the humidity level is raised to a range of 40 to 60%. Of course, using humidifiers or air purifiers cannot cure you if you are already sick due to allergens. But they can help relieve the symptoms so that you feel less miserable. 

Is It Safe to Use an Air Purifier and Humidifier Together? 

Yes! You’ll be able to breathe easier by removing things like dust mites and pollen from the air while also adding moisture to it. They may not both be necessary at the same time, depending on your environment. 

Experts recommend using a humidifier during winter months when heating systems may create a dry environment. Air purifiers remove allergens and other pollutants from the air, which is especially important if someone in your home has asthma or allergies. When combining these two products, it’s recommended that you place the humidifier close to where people spend most of their time, like in living areas and bedrooms.

Air purifiers are often more expensive than humidifiers, so you may want to purchase the air purifier first and then get a humidifier if needed. If your home is too dry and dusty, investing in an air purifier with built-in dehumidification might also be a good decision for you.


An air purifier and humidifier are both great products to have in your home. The best option for you will depend on a variety of factors, including the size of your space, how often it is used, what types of allergens or pollutants may be present, as well as whether you prefer more cool or warm air.
