Can You Use Dehumidifier and Air Purifier in the Same Room?

Since the spread of the coronavirus, several people have chosen to use air purifiers. This is an additional form of protection in hopes of cleansing the air. Aside from the coronavirus, air-related diseases have become a severe discussion. Because the air in their room may contain aerosols that carry the virus. However, several people also prefer to use a dehumidifier. But due to pollutants, some consumers may have both. It has similar benefits, which begs the question, can you use a dehumidifier alongside an air purifier in the same room?


🍃 An air purifier is an electronic appliance that is used to filter and cleanse the air. Air may have dust particles, microbes, radon, odors, smoke, and various aerosols. These can’t usually be cleansed by using standard cleaning equipment. It works by collecting dirty air and filter it through different stages. After filtering, it will release air cleansed and sterilized.

🍃 A dehumidifier is an electronic appliance similar to an air purifier. Its main purpose is to reduce the moisture and humidity in the air. High levels of humidity can usually cause various problems in the room. Too much moist can lead to the formation of molds and spores that can add to indoor pollutants.

Both of these appliances work similarly by applying changes in the air of a room. However, they have different varying uses and benefits depending on what the residents of the household need and what issues they may face in their respiratory health.



1. Removes dust particles that are floating in the air, which usual cleaning products can’t usually remove.

2. Eradicates pollutants and allergens that can pose a threat to people with respiratory problems such as asthma.

3. Reduces the chance of becoming infected with airborne diseases.

4. Eliminates terrible odors that can trigger respiratory diseases like asthma.

5. Promotes good sleep and therapy to external stress.


1. Removes excess moisture in the room that can cause less visible mirrors and windows, mold growth in walls, and build-up of moisture, especially during rainy seasons, which causes wet marks in the walls or ceilings.

2. Prevents certain pests who prefer living in moist areas from entering your house.

3. Reduces the growth of microbes that thrive in moist environments.

4. Eliminates certain allergens, such as dust mites, that can grow in excessively moist environments.

5. Prevents the damage caused by excess moisture to particular possessions (such as books and electronics).

Similar benefits of both appliances are preventing diseases, and allergic reactions hinder the growth of harmful microbes that can affect both the household and its inhabitants and improve overall respiratory health.


Several people more prefer the air purifier for its general cleansing effects on the air of the room since the dehumidifier is for a more specific purpose. Air purifiers gained even more popularity because of the pandemic despite certain issues that some people mention, such as their ecological effects. However, it is proven that alongside following protocols, air purifiers can help eradicate the virus that may have entered the room through aerosols and droplets in the air.

It is also worth noting that even though the air purifier can destroy the allergens and diseases that the dehumidifier can also eradicate, it can’t perform the same specific role that the dehumidifier can, which is keeping the humidity and moisture levels of the room stable. They can both help in cleansing. The difference between the two is in their technicalities and worthiness


🏠 The answer is yes. However, there should be a distance between the two appliances, which may not be suitable for smaller rooms. This distance is necessary because the humidity that the dehumidifier is absorbing is not suited for the filtering system of the air purifier. So if the two appliances are near each other, it may cause moisture to build up in that area, which can damage the filtering system of the air purifier.

🏠 If you are planning to put these two appliances in the same room, always make sure to put them where they are the furthest away from each other as much as possible. Preferably, they are being placed in two opposite corners of the room so that the moisture that the dehumidifier is absorbing is far away from the area of the air purifier, thus causing minimal to no damage to its filtering system. However, this is not to say that it is always optimal to keep these two appliances together because the owner has to make sure that they are prepared for the cons of having these appliances.

The Cons Of Having Both Appliances In The Same Room

Having both of these appliances may be beneficial to health. They work the same as to clean the air we breathe. But everything has its own diadvantages. It would help if you looked for these downsides to avoid accidents and avoid spending more than the set budget.

High Maintenance

Both of these appliances require you to have the budget, time, and effort for their maintenance. Buying these appliances first off can be quite pricey, and the cleaning you have to provide for each one can be quite time-consuming for both your time and energy. It is always a good idea to think of which one you need the most. And if you can be accountable to provide the maintenance to ensure it lasts longer. Remember that if something goes wrong with high-quality appliances, it’s better to buy a new one than to spend on its repair.

Energy Consumption

The air purifier is known for giving additional numbers for your electric bill. But having a dehumidifier alongside it can boost your electric bill to an even more significant amount. You can try to test one appliance first and see how much energy it consumes. As a result, if you can sacrifice your budget for that additional price before getting both appliances. And aside from having these appliances, remember that you still have other electric-consuming materials in your house.

Having Both May Not Work Well In Small Spaces

As previously mentioned, you need to have a reasonable amount of distance between these two appliances. So if you are planning to keep them in a room that is relatively small, it can potentially damage your air purifier, which can lead to even more expenses. Both appliances need enough space to let the machine work properly. Lastly, it is not practical to have both if you have a small space because each needs a larger space to ensure proper airflow.


Having both of these appliances can serve you effectively if you are able to manage those cons. The maintenance and energy consumption is much smaller than the bills you have to pay in the event of some conditions. These conditions are respiratory illness, pest control, or the damage done by moisture to your furniture and electronics. Preventions are better than cures. Having these appliances can definitely do more good than harm as long as you are willing to provide time and energy in order to keep them in good maintenance.

But if you cannot afford to acquire these appliances, you can maintain cleanliness. Disinfecting and sanitizing using mild cleaners may help, and just take notes of the harmful chemicals that may add as a pollutant and allergen. There are also available inexpensive air sanitizers that work the same. But before acquiring such appliances, make sure that your electricity box can handle its power to avoid a short circuit leading to an explosion and fire.
