When it comes to air devices, these machines work amazingly well for getting rid of air pollutants. 

However, do air purifiers dehumidify? 

Air purifiers by themselves do not dehumidify. They are designed to clean the air by getting rid of dust, allergies, particles, pollen, pet hair, mold, and unhealthy airborne contaminants

In this guide, I’ll be going over with you all the questions you may have about air purifiers. As well as some important facts about them.

Let’s jump in…

Do Air Purifiers Dehumidify?

In short, Air purifiers do not have a dehumidifier function. And are unable to dry out the air.

On the other hand, a dehumidifier machine is known to reduce excess moisture. And works incredibly well to extract water from the air.

Can You Get A Dehumidifier And Air Purifier In One?

Although, you can use an air purifier and a dehumidifier in the same room. They can work well together. But the problem with that is, you’ll have to purchase two devices. And that can be expensive. 

However, there is another option that you can go for. And it will save you time and money.

An air purifier and dehumidifier all in one is a good option. By having a dehumidifier and an air purifier combo you will receive the best balance of each device. You can dehumidify a room and clean the air at the same time.

For example, on the air purifier side, it will help to purifier the air by removing dust mites, allergens, and pollutants. And the dehumidifier helps humidity levels in your home. 

By using both in your home not only will you be able to breathe better.

But you’ll also have clean indoor air that is odor-free.

Not to mention, you will have a more comfortable living space.

Key Features To Look For In An Air Dehumidifier Combo:

There are many options on the market to choose from. Keep in mind, they are not all the same. Some are better than others. However below you will find a list of key features to look for when choosing a device.

True HEPA Filtration-

Do air purifiers remove humidity?

One key feature, that is a must-have in any air purifier is a True HEPA filtration filter. This filter blocks out 99.97% of allergens and contaminants as tiny as .03 microns. These airborne particles include pollen, pet dander, household dust, and even tobacco smoke. 

Most importantly, some air purifier brands advertise as having a Hepa filter. But there is a big difference between HEPA and True HEPA filters.

Let me explain the differences…

Normal HEPA Filter:

Captures 99% of particles that are .02 microns in size. Also, the filter is made up of fiberglass and is less dense. Another negative feature is that a regular HEPA filter can not trap as many airborne contaminants as a true HEPA filter can.

True HEPA-

As previously mentioned a True HEPA filter has an efficiency rate of 99.97%. It blocks allergens and can even block bacteria and viruses. This is because it is a highly dense filter.

Noise Level

No one wants a loud machine. Not only, can this affect your sleep, but also can make an uncomfortable home environment. When looking for an all in one machine it is important to take into consideration the noise level of the device. 

With this in mind, all dehumidifier combos have different noise rating.

For this reason, the best devices are the ones that are peaceful and quiet. If you don’t like the sound when the machine is running. Than an ultra-quiet operation is the best option. 

Another key point is to look for a machine that has a noise rating in the range of 35-42 bd. This will be quiet enough that you won’t even notice when it is running.


When it comes to an Air Dehumidifier w/Air Purifying Function they are compact. And smaller than a normal size dehumidifier. This is because they have two functions. 

So keep in mind they are not the normal size dehumidifier. It is important to choose an air dehumidifier and air purifier combo that has a larger water tank capacity. A larger water tank equals longer working time.

Tenergy Sorbi air purifier combo is well known for having a 1-liter water tank. And it can remove 750ml/day. Plus it is lightweight and has TRUE HEPA FILTRATION. 

Additionally, it is highly reviewed. You can find it here on amazon.

Summary (Do Air Purifiers Remove Humidity?)

In summary, Do Air Purifiers Dehumidify? 

The answer is no. Air purifiers by themselves are not enough to dry out the room and remove humidity.

On the other hand, an air purifier with a dehumidifier combo is available on the market. And is a popular choice when wanting both options in one device. 

In fact, by having an all in one machine you can receive the benefits of both worlds. 

Therefore, improving air quality, eliminating allergies, and harmful air pollutants in your home. While getting rid of odors, mold, pet dander, and smoke. You can do all of this with just one single device. Instead of paying for two.
