Shopping for an air purifier and dehumidifier all-in-one combo? 

You’ve come to the right place. 

According to the EPA, indoor air quality is five times worse than outdoor air. 

And while closing doors and windows helps conserve energy and keeps some harmful pollutants out, it also traps airborne allergens inside that can cause health issues. 

While you can use an air purifier to address this issue, it can’t reduce the humidity that often breeds allergens like fungi and mold. 

For this, you need a dehumidifier. 

Fortunately, you can purchase an air purifier and dehumidifier all-in-one device that improves air quality by filtering out contaminants and removes extra moisture from your home. 

In this guide, you’ll learn all about these unique air machines.  In addition, we recommend a few of our favorite models.

Do You Need an Air Purifier and Dehumidifier Combo?

While you can invest in an air purifier and a dehumidifier separately, a combination unit is a better purchase. 

With a combination unit, you will save on energy costs by running just one device in place of two. 

Plus, a combo unit will take up less space than two separate units.

Our Review

The first thing we noticed about this unit is its design. It is sleek yet minimalistic, making it perfect for any modern interior. With its large capacity, you can use it in any part of the house, especially the basement and living room. 

It also features 360° wheels and ergonomic lift handles that allow you to easily move it from one place to another. 

The Waykar model features an easy control panel on top. It has a digital display with 4 buttons for power, fan speed, timer, and settings. A light on top of the display indicates when the bucket is full. 

You can adjust the fan speed according to your needs and even set it to turn off itself with the 24-hour timer function. It also comes with washable and reusable filters, which saves you the cost of frequent filter replacements. 

The device also boasts intelligent technologies such as auto-shutoff and humidity auto control. 

The automatic shutoff turns off the device when the water reservoir becomes full. 

Meanwhile, the humidity auto control sets a target humidity level and turns off once the humidity levels reach the target range.

Also known as the “Moisture Maniac,” the Vremi 50 Pint Dehumidifier can remove 50 pints of moisture per day and is suitable for spaces from 3000 to 4500 square feet. 

It has a simple and clean look that goes well with most decors and has convenient built-in handles and wheels for convenience. 




Our Review

This is one of the best-selling units from Vremi. It boasts a powerful performance with 40 pints of moisture removal per day. It also doubles up as an air purifier, removing dust, pollen, and other contaminants from the air. 

It is equipped with a washable filter that you can reuse, saving you from the hassle of buying a new filter every time. 

A noteworthy feature of this device is its built-in humidistat. It is a technology that monitors the humidity levels and automatically adjusts the speed accordingly. 

It allows you to adjust it at 5% incremental settings between 40% and 70%. Its high capacity can cover medium to large spaces, ranging from 3,000 to 4,500 Sq ft.

The device is designed to be temperature-resistant. It can operate at temperatures as low as 5°C and as high as 35° C. 

You can also choose between three drainage options; built-in water reservoir, direct-to-drain with a hose, and with pump draining. The hose for direct draining is included in the package, but you might need to purchase the pump separately.

The Afloia Air Purifier and Dehumidifier with True HEPA Filter is a low-priced combination unit. It comes with a 1000 ml tank capacity and a true HEPA filter to remove extra moisture and the smallest particles from the air.




Our Review

The Afloia air purifier and dehumidifier is a powerful yet energy-efficient device. It is quite compact (dimensions: 8.5 x 7.8 x 12.4 inches) and doesn’t weigh much (only 5.9 pounds), so you can easily move it from one place to another. 

This small device can remove up to 750 ml of moisture per day. However, for such a small unit, its wide operating temperature range of 59°F to 86°F is pretty commendable. 

The Afloia combination unit is cylindrical, which deviates from traditional rectangular designs. It pulls in air from the front and blows out clean and dry air from the top. 

But what makes the Afloia dehumidifier and air purifier stand out is the filter. While other models usually have a washable filter, this unit has a true HEPA filter that can remove particles as small as 0.3 microns. 

It delivers cleaner air by capturing both large and small particles, and makes your home a better place to live in.

Buying Guide

How Does the Air Purifier and Dehumidifier Combo Work?

air purifier dehumidifier combo reviews

An air purifier and dehumidifier combo works in a similar way as its separate counterparts. It filters the air to capture airborne particles such as dust, bacteria, pet dander, mold, etc. while condensing excess moisture to remove it as water as well. 

It is usually equipped with a reusable or a High-Efficiency Particulate Absorbing (HEPA) filter to remove nanoparticles measuring up to 3 microns. It also has a water tank to collect all the water, which needs draining when the air moisture is removed. 

Some of these units allow you to turn off the dehumidifying function. When the air is dry enough, you can turn it off. This way, the air-purifying function will continue to clean the air.

Why Should You Buy an Air Purifier and Dehumidifier All-in-One?

Most people find combo units odd when there are separate units available. However, you can’t deny the convenience they promise. Here are some reasons why you should buy an air purifier and dehumidifier all in one:

Save Space

air purifier dehumidifier combo

If you decide to purchase a separate air purifier and a dehumidifier, you will need to make space for both devices in your home. Depending upon the models, they can be big and bulky and take up too much space.

But with an air purifier and dehumidifier combo, you will get a single device that will perform both functions without occupying too much space.

Improve Air Quality

Do you or any of your family members suffer from respiratory issues? If yes, you should definitely look into getting a combination unit. The combo unit clears the air of allergens and irritants, like dust; mold, fungi, pollen, etc., making it clean and safe to breathe in.

On the other hand, such units also control humidity levels and remove extra moisture to significantly improve the air quality around your home.

Conserve Energy

Buying two separate dehumidifying and air purifying units means jacking up your energy bills because both devices will consume their share of energy, putting an extra burden on your budget.

However, a combination model will single-handedly serve both purposes while consuming only one device’s worth of energy. Hence, they conserve energy and put less strain on your budget.

Create a Safe Indoor Atmosphere

An air purifier and dehumidifier all-in-one unit creates a safer and healthier home atmosphere. Allergens like mold and mildew are significantly detrimental to health and well-being. Their spores float around in the air and when the air is moist, they get a chance to grow.

A combo machine removes both the spores and the moisture, preventing them from flourishing inside your home.

What to Look for in an Air Purifier and Dehumidifier All-in-One Machine

While these combo machines are definitely useful, they are quite difficult to purchase. The reason is not lack of availability. In fact, the market is filled with such a huge range that choosing just a single unit for yourself is quite a task. They all boast different features which makes the choice tougher.

To help you out, we have listed some features that set different units apart from each other.

Tank Capacity

air purifier and dehumidifier all in one

Different air purifier and dehumidifier combination units have different tank capacities. One unit may collect 1 liter of water while the other may remove up to 70-pints of moisture from the air.

You should choose a model depending upon the humidity levels in your area. We think that a model with a bigger tank capacity is better because you won’t need to empty it as often. A smaller tank will fill up quickly and will frequently need emptying.


Portability is an important consideration in an air purifier and dehumidifier unit. If a unit is portable, you can easily take it from one part of the house to another.

For this purpose, different units come with wheels and handles, support remote control operation, or have an internal condensate pump that automatically removes the collected water from the machine. Look for a machine that has most of these features for more convenience.

Coverage Area

Perhaps the most important consideration in such a device is the amount of area it can cover. As a rule of thumb, you should always choose a device that can cover the area larger than where you plan to set it up. 

The coverage area of each machine is mentioned on the product. You can measure the square footage of your room and choose a unit accordingly.

Energy Efficiency

Since you are opting for a combination machine to conserve energy, it is best to look for a highly energy-efficient model. 

Some units consume less energy than others; you should also look into getting such a unit, so your energy bill doesn’t exceed considerably.

Ease of usage is also an important consideration in a combination device. During our research, we came across some devices that were quite feature-rich yet complicated to use. 

When choosing a unit for yourself, go for a machine that is straightforward and easy to use. Features like digital display, timer functions, and auto-shutoff are some to be sought-after. A filter change and bucket-full indicator also make operation easier. 

Also, check how easy it is to remove and reinstall the water tank. Since you will regularly remove it from the device to empty it, choose a unit on which it is easy to do so. 

Operating Temperature

Such devices have different operating temperatures. It’s better to choose a device that has a wide range of operating temperatures because it can operate at both high and low temperatures without any difficulty. 

Environmental temperature affects your machine’s overall performance, so go for a model that can operate both in hot and cold weather.


The machine’s performance is regulated by the type of filter it has. Most air purifier and dehumidifier combos feature HEPA filters because they can trap the smallest of particles. So it is a must-have in your machine. Some also have carbon filters to remove odors, so it is also good if you can get that.

Pros and Cons

dehumidifiers air purifiers

With air pollution increasing day by day, the concern about clean air is also increasing. Low-quality air is a serious health hazard. That’s why both air purifiers and dehumidifiers are a must-have inside any home, or you can look into getting a combination of both. 

Air purifiers and dehumidifiers all-in-one units are a fairly new invention. They are remarkable devices that can help you in your fight for clean air. However, they also have some disadvantages associated with them. 


Contaminant-Free Air

Airborne contaminants are a major health risk. Dust particles, germs, viruses, bacteria, etc., enter your body with the air and cause serious infections in your body. The recent Covid 19 pandemic is clear proof. 

But this machine, with its air purification features, sifts the indoor air, removing these harmful particles and making it clean and contaminant-free. HEPA filters can remove particles as small as 0.3 microns, so the unit blows out 99.97% clean air around your home. 

Space-Saving Option

Not everyone is lucky enough to own a huge house with lots of free space to enjoy. So for small homeowners, buying a separate dehumidifier and air purifier is not an option because they don’t have much free space. 

A combined air purifier and dehumidifier shines in such situations because the combination only takes up the space of a single machine. Additionally, you won’t need to move two separate machines around the house to boost air quality in different areas. 

Prevent Condensation

When the air is humid, the extra moisture tends to condense on different surfaces, leading to a plethora of issues. The most worrisome is mold, which is not only a health hazard but also a threat to the integrity of your home. 

Using the dehumidifier function of the device, you can say goodbye to the extra moisture, which makes the air heavy and difficult to breathe in. 

Save Money
dehumidifiers air purifiers

Regardless of the amount of money you have, it is a good idea to make smart investments. An air purifier and dehumidifier combo is one such purchase because it is a two-in-one unit that saves you not only from the cost of buying two separate machines but also from having to pay energy bills. 

Contrary to the two separate devices drawing energy for themselves, the combo will only consume the energy of a single device and deliver the benefits of both. 


Dry Air

While humid air is certainly bad for you, dry air also causes some issues. It causes dry skin, cracked lips, dry sinuses, and sometimes even a bloody nose. If you leave the dehumidifying function on for long, it may cause the indoor air to become too dry, leading to the issues mentioned above. 

Filter Replacement Costs

Because of its efficiency, a HEPA filter is somewhat expensive. Depending upon the quality of the air inside your home, you will need to replace the filter in your machine every four to six months, which can become costly in the long run.

Frequently Asked Questions

Is a Dehumidifier-Air Purifier combo more effective than buying individual machines?

There are several ways to answer this question, and different people will have different answers. 

For example, a small homeowner who does not have much space will find the combination unit more effective, while people with bigger houses might appreciate individual units. 

Similarly, people who want to conserve energy and reduce their energy bills will recommend a combo, while people who don’t want to compromise on air quality will invest in a separate air purifier and a dehumidifier. 

In the end, it all comes down to the individual needs of every user. If you ask us, we think that combination units are certainly a smart choice because of their dual-function and cost-efficiency.
