Air purifiers vs humidifiers: 5 Best Air Purifier-Humidifier Combos

Updated: May 10, 2022

Although both humidifiers and air purifiers can impact the air quality in your home, each one has unique advantages. You should be able to tell the difference between an air purifier or humidifier. This will help you to avoid dry, irritable, or allergic conditions.

We'll explain the differences between each device and how to use them safely. We've also included our list of 5 great air purifier / humidifier combos that you can get online, so that you can enjoy the best of both worlds.

What's the difference - Air Purifiers vs Humidifiers

An air purifier cleans the air by "inactivating" or removing pollutants. An air purifier consists of a fan and a filter. However, the specific technology used to clean the air can vary from HEPA filters to ionizers or PECO technology.

Air is circulated through most air purifiers. Pollutants are captured or removed by a filter, and then clean air is released back into the room. Air purifiers don't add moisture to the air.

A humidifier on the other hand does not clean the air. It simply adds moisture to the air by heating water into steam, vibrating water droplets in the air, or evaporating it using a fan with a wick.

If tap water is used in lieu of distilled water, ultrasonic humidifiers can also introduce small mineral particles to the air. Although the health effects of these particles on the body aren't well-known, research has shown that they may have some effects upon lung tissue.

The EPA recommends that you use distilled water and that your humidifier be cleaned and disinfected regularly.

How do they benefit your health - Air Purifiers vs Humidifiers

Humidifiers and air purifiers can have different effects on the quality of air, which can improve your health differently. There are some differences in how it is advantageous to have air purifiers vs humidifiers. These are the most common benefits that they have:

Allergies and asthma

Some purifiers can reduce allergens such as pollen, dust mites, or pet dander. Air purifiers are great for people suffering from asthma or allergies. These allergens can be carried in tiny particles suspended in the air. They can stay suspended for hours. These particles are captured by traditional air filters, but the Molekule purifier can destroy them and HEPA filters can remove them from the air.

Humidifiers on the other hand have no effect on allergen levels. Humidifiers may make symptoms less severe if your nose is dry or irritated. Humidifiers don't reduce asthma symptoms or allergy symptoms (Gonzales, Svendsen & Commodore (2018)).

If a humidifier doesn't get cleaned properly, it can become moldy and introduce mold spores to the air. This can trigger allergy and asthma symptoms. If you do use one, make sure that it is cleaned regularly.

Respiratory irritation, colds, flu, and other symptoms

While common air purifiers trap particles in the air, some viruses can still pass through regular filters. Although an air purifier can't treat a cold or flu, it may help to relieve symptoms by eliminating other respiratory irritants.

A humidifier, according to NIH may be able to relieve a stuffy or irritable nose. A humidifier may provide protection against viruses if it is set at the right humidity level. Multiple studies by Lapidus and colleagues (2013) show that increasing humidity to 40-60 percent can reduce the risk of contracting viruses.

A humidifier can't cure you if you are already sick. However, it can reduce symptoms by keeping your nose and throat dry.

Dry Air

An indoor purifier doesn't add moisture to the air. This can lead to a variety of respiratory conditions, such as asthma and sinusitis in extreme cases.

Humidifiers increase the humidity in the air and improve dry air conditions. It can cause irritation to your throat and nose if the air becomes too dry, especially in winter.
