How to tell the difference between an air purifier and a humidifier

Despite the fact that many people mistakenly use these terms as synonyms, there are differences between them. We will find out the difference between air purifier vs dehumidifier in this article. A combination unit of both these products is also on the market. Now let’s see the differences between these two units.

Air Purifier

A purifier filters a variety of contaminants. The devices are capable of removing smoke, pet dander and mold spores. Airborne particles can be removed from the unit when it is in operation.

The HEPA versions of these filters can filter out 99.97% airborne particulates. The contaminants in the air can lead to respiratory issues, allergies, and asthma.

HEPA Filters are typically made from fiberglass and threads of plastic. These filters have a tight weave and are unable to let pollutants pass. You must remember that these units are not able to add or remove humidity from the air. They only filter air pollution.

Other than that, they aren’t air humidifiers. This is why you should consider the difference before you begin to process this unit.


Humidifiers are designed to provide moisture into the air. This humidifier generates water vapour and then releases it into the air. In fact, the biggest difference is between the two. Dehumidifiers are designed to reduce moisture levels in a room. The reverse function of this unit makes it a good choice.

You can continue adding water to the unit reservoir if you’d like to have a humidifier that adds moisture to indoor air. This unit generates fine mist that is spread across the room.

You should place a humidity-deficient room humidifier. A lack of humidity can cause breathing issues, sinus problems, throat irritations, and even android skin.

Keep in mind that humidifiers can increase the relative level of humidity in a space. A high humidity level can lead to mold. The relative humidity in your room is ideal between 30-50%.

All of these issues can occur if relative humidity falls below 30%. You may also have mold and mildew if your relative humidity exceeds 50%.

We suggest you get an air purifier if, for some reason, you can’t reduce the level of humidity in your bedroom. You can also filter mold spores with these devices.

In a nutshell, here is a list of major differences in air purifiers versus humidifiers. Hopefully these tips can help you select the unit that best suits your requirements.
