What is the Difference Between an Air Purifier and Humidifier?

Do you know the difference between an air purifier versus humidifier? They both work to improve your indoor air quality, but there are differences in how they operate and what they do. Here’s what you need to know.

Air Purifier

Air purifiers do just as the name suggests – they help to purify and clean the air in your home. Using a filter and a fan, they pull in pollutants that the filter then traps and prevents from recirculating through your home. They can remove more than 99% of airborne contaminants, including dust and dust mites, pesticides, pet dander, mold, chemicals, pollen, and more.


Unlike an air purifier which filters the air, a humidifier improves air quality by adding moisture. When the air in your home is too dry, it can lead to feeling unwell, increase the chance of getting sick, and impacts your mucus membranes. Increasing the humidity level has many benefits, including reducing the presence of viruses, relieving dry skin, reducing congestion, and relieving asthma and allergy symptoms.

Which is Best?

Whether an air purifier or a humidifier would be a better choice depends on many factors. There is an option to install a combination unit. An integrated system gives you the best of both types of equipment by cleaning your air while bumping up the humidity.
