Benefits of Getting a Dehumidifier and Air Purifier Combo


As mentioned earlier, there are perks that a dehumidifier and air purifier combo can provide. We already said that it can keep your home safe and clean. However, in this section, we will dig deep and discuss how these machines can do that for your home.

Safer Place

Due to high humidity and changes in temperature, your home can develop fluctuations of humidity in the atmosphere. The rise of humidity levels can result in the buildup of more moisture. Damp or rooms that are too humid could result in the formation of harmful particles like molds and mildew. These microorganisms when inhaled can cause difficulty in breathing. Such incidents can be dangerous especially for people who have sensitive lungs.

Therefore to make sure you will get to balance the humidity levels in your room in other areas of your house, getting a dehumidifier can resolve this dilemma. A dehumidifier can dry up a room and absorb excess moisture that is building up in an area. This could result in the elimination of particles like molds, and it can even prevent such harmful microorganisms to form in the future. This is how a dehumidifier can make your home a safer place for you and your loved ones.

Cleaner Air

Do you know how an air purifier works? Maybe you have already heard about it, but here will tell you how this machine can clean your air. There are microparticles in the air that can be hazardous to people with allergy or asthma. These particles are called allergens which can be dust mites,  pet dander, pollen, and so on.

When inhaled by a  person who is sensitive to these microparticles, it can result in constriction of the air passages in the lungs. It can also cause sneezing, or itch in the eyes and nose. Air purifiers work using filters like a HEPA filter which can gather and trap microparticles like allergens. These machines, therefore, can result in cleaner air in your rooms.

Save Money

You can always separately purchase a dehumidifier and an air purifier. But why would you do that if you can buy one product that can do both? A dehumidifier and air purifier combo can help you save money as you won’t need to buy two different products. However, most products that can both dehumidify and purify the air can only cover small areas. If you just need such models for home-use, the smaller units can work great.

However, if you’re looking for a model that can work for large spaces, you may want to opt for more powerful and bigger units. Nonetheless a product that can do both dehumidifying and air purifying is an excellent choice if you’re opting for a safer, cleaner, fresher air to breathe inside your home.

Factors to Consider When Getting a Dehumidifier and Air Purifier Combo


To make sure you’re getting the right product, there are a few factors that you should consider before you get a dehumidifier and air purifier combo. The features below are just a few of the factors which you should check in a product you’re getting. There are a few more other highlights and capabilities that you should look for a 2 in 1 machine that can purify and dehumidify the air.

However, the factors we discussed below are some of the most crucial features you should know about. Learning about these factors can help you purchase the perfect product for your needs. 

Pint Per Day

The volume of moisture that a dehumidifier can gather is typically measured by pint per day. This feature is also called the product’s moisture removal capacity. It means the amount of excess water in the air that the product can gather. Most of the time, the product’s ability to gather moisture in the air depends on how powerful and immense is the machine equipped in the dehumidifier.

Typically for models that can do both dehumidification and air purification,  it can collect about 750 to 1000 ml of moisture in the air. Products like this are usually for home use. For more powerful models that cover larger areas, in most cases, these dehumidifiers can gather up to 40 pints per day or more.

Water Tank Capacity


The water tank capacity must compliment the product’s moisture removal capacity. For smaller models that are used for homes, a water tank of 1,000 ml is good enough. However, if you’re looking for a model that can cover large spaces, you must opt for a machine that can gather large pints per day. The size of the water reservoir of the machine you’re getting also dictates how frequently you should empty its contents. The smaller the water tank capacity, the more frequent you need to unload the reservoir.

However, in some models that do not require manual emptying of the water tank, an option for continuous draining is available. This feature allows you to connect a hose from the water tank to drainage, which works using gravity or a pump system. Models like this are easier and more convenient to use as you won’t worry about regularly emptying the water tank. 

Coverage Area

The coverage area of the product you’re getting plays a crucial role in the product’s efficiency. You can find models that can work or cover a space from a small 200 square feet area to 2,000 square feet or more. You will know which one unit by first identifying where you are planning to place the machine.

If you’re planning to use the product for small rooms like the bathroom or the kitchen, you can opt for dehumidifier and air purifier combos that are good for small spaces. The rule of thumb, though, is to get a machine that can cover a larger space than where you’re planning to place it. It’s always better to get a model that has a bigger coverage area than the room where you will use the machine.

Ease of Use


There are a couple of features that support the product’s ease of use. For instance, features like auto shut off, and automatic humidity control are both highlights that make the product easy to use. The automatic shut-off feature turns off the machine whenever the water reaches its full capacity. This feature also turns on the machine on its own when the water tank has been emptied.

On the other hand, automatic humidity control provides convenience for the user. With this feature, the model can sense the humid of the room, and then sets the right humidity levels to achieve healthy amounts of moisture in the air. Another feature that supports the product’s ease of use is the controls. Some models are plug and play without needing you to pre-set up the machine.

They’re also other dehumidifier and air purifier combos that come with easy touch button controls, where you can conveniently set up everything you need for the machine.


When getting a humidifier and air purifier combo you should also consider if it’s easy to carry. Portability is an important feature for this type of machine because you usually move the product from one place to another. Therefore, the more compact and lightweight the product is, the better especially if you know you will use it in different areas of your home.

However, if you’re willing to buy multiple units for each area of your home, you may skip this feature. Still, we recommend a product that is portable as you can bring it anywhere you want to go even if you’re going to use it during your travels or outdoors. 

Operating Temperature Range

The operating temperature range of a dehumidifier and air purifier combo determines its versatility when it comes to temperature changes. Usually, you will find models that can work from 45 degrees Fahrenheit to 122.  Due to the changes in temperature of a room, the coils of the machine can form ice which can stop it from working.

But if you’re going to get a product that has a wide temperature range, you won’t need to worry about getting frosted coils. Getting a model that can defrost on its own is highly recommended as well especially for heavy-duty dehumidifiers. Furthermore, an auto defrost feature also prolongs the lifespan of the product as it protects the coil from damages.



When getting a dehumidifier and air purifier combo you must also check what kind of filters are equipped with the product.  For excellent air purifiers, you will usually find HEPA filters. This type of filter can’t trap up to 0.3 microns of particles in the air. You can also gather up to 99.97 percent of these microparticles and efficiently keep them inside the filters. You may also want to get a unit with washable or reusable filters.  This way you can save costs as you won’t need to regularly replace the filters.

Noise Level

Some models can be noisy. If you’re planning to use a dehumidifier and air purifier combo for long hours, you should consider how much noise the machine produces. Typically, noise levels of 42 decibels are considered quiet machines, which work without disturbing the people near it. Many dehumidifiers are used for 24 hours straight especially during the high humid seasons. 

Therefore, it’s just wise to get a machine that can work without producing too much noise, giving you the freedom to keep the machine going for as long as you want.
