Allergies: Humidifier vs Air Purifier

There can be confusion between a humidifier and an air purifier because it seems like they both help with similar issues. There are, however, quite a few differences between the two, and knowing these differences can help you better decide what you actually need to purchase.

When to use an air purifier

Air purifiers are mainly used for issues that are associated with allergies, asthma and any other respiratory problems. Air purifiers help to cleanse the air within the room or house, and help to filtrate out any dust, pollen, pet dander in the air. The result is clean and fresh air that helps in alleviating any symptoms that individuals with the issues above may have.


Air purifiers help to filter the air, and hence there are plenty of different types of filters on the market. It’s best to purchase an air purifier that utilizes mechanical filtration. This means that the air purifier will usually physically trap the pollutants that pass through them.

The main filter is an important component of an air purifier and a HEPA filter is usually what you should be looking for. While you do need to replace HEPA filters regularly, they help to trap 99.97% of particles. You do want to be careful with purchasing air purifiers with HEPA filters as some of them falsely advertise them. You should opt for a reputable brand that uses either HEPA or true HEPA filters.

Other filters include electrostatic filters but there isn’t really a filter replacement and only about 30% of airborne particles are eliminated. Ozone filters help to eliminate heavy odors, mold and more but they’re also extremely dangerous and generally unsafe for residential use. Another popular filter is ionizers as they clump airborne particles into larger particles and is a great complement to HEPA filtration. Ionizers can be effective without HEPA filtration though, so it’s important that they work in tandem.

When to use a humidifier

The main function of a humidifier is to help in adding moisture back into the air within your home. How a humidifier works, is that it pumps water vapor into the room. To keep the humidifier running, you usually add water to a reservoir which will then convert this into a fine mist that is released into the air.

Most individuals that use humidifiers do so because they need moisture to be added back into the air as the air within the room or the house is exceptionally dry. Humidifiers also help in relieving dry skin, sinus issues, throat irritation, nose bleeds and more.
