Are you currently confused whether should you choose air purifier over dehumidifier or otherwise?

In case you have missed it, both the air purifier and dehumidifier are effective appliances in terms of improving the quality of air that you breathe in, especially when at home. However, there are significant differences between the two – from its features to its main purpose.

So, to find out which makes more sense, you have to carefully read this post and other similar reliable posts about choosing between the air purifier and the dehumidifier.

How does air purifier work?

Air purifiers have internal fans that pull the air and passes through a series of filters, which helps remove harmful airborne pollutants such as smoke particles, dust, pollen, and other respiratory disease-causing-particles found in the air inside your home. Then, it circulates the clean air back to the room, while it sucks in dirty air back to the air purifier to separate the clean and the bad; this whole procedure repeats itself multiple times a day until you have to turn off the air purifier.

How does dehumidifier work?

The dehumidifier works much like an air conditioner, when the warm and moist air enters the device it passes through the refrigerant cooled coils. And as the air starts to get cool, the moisture starts to condense. Then, by the time the moisture is removed, the air that had entered earlier is being re-heated through a heat recovery system. Afterward, the re-heated air is returned back to the room at 2 degrees Celsius warmer and noticeably drier than before.

The main function of dehumidifier is to remove the excess moisture present in the air; thus, it helps to eliminate all the possibilities of harboring dust mites, mold, and other allergies-causing-organism.

The mechanics of both devices show how different they are from each other. For a more clearer understanding, here are each device’s pros and cons.

Air Purifier

  • Pros:

o    It helps clean the air from disease-causing-airborne particles.
o    It helps remove some of the mold spores.
o    It helps clean your home from harmful microscopic debris.
o    It is best for people with asthma and other respiratory problems.
o    It is easier to maintain

  • Cons:

o    It does not have the ability to regulate humidity within the room.
o    Some air purifiers are noisy


  • Pros:

o    It is excellent in removing or regulating the surrounding humidity.
o    It helps prevent the formation and the spread of mold spores, especially on areas that are often humid.
o    It can remove particular allergens such as dust mites and mold, which the air purifier is unable to do so.

  • Cons:

o    It is unable to remove disease-causing- dust and toxins present in the surrounding air.
o    Some dehumidifiers are a bit noisy.

So, which one makes sense?

Well, both devices make sense; however, if you are still choosing between an air purifier and dehumidifier, you have to determine your current needs when it comes to keeping the air healthy inside your home.

Is your place mostly humid – day and night? Well, you need a dehumidifier. However, if your place is well-ventilated but you have allergies with pet dander or pollen, you have to choose air purifier.
