Air Purifier vs. Dehumidifier: Which Is Best for Mold Removal?

Your family has been experiencing some respiratory problems, and there’s also an awful smell that lurks in your home. You suspect that mold could be the cause of all these. 

You’ve tried different sprays and deodorizers, but nothing seems to solve the problem. Have you tried an air purifier or a dehumidifier? These devices have been proven effective in eliminating mold and preventing reproduction. 

In this article, we look at the difference between air purifiers and dehumidifiers, so you can see which might be best for your situation. 

Air purifier vs. dehumidifier – What do they do?

You can use a combination of air purifier and a dehumidifier to clean the air and control mold in your home. However, one device can’t be a substitute for the other.  

The function of an air purifier is to get rid of air pollutants from the air in your environment. These pollutants may include dust, mold spores, bacteria, allergens, and pet dander. An air purifier is equipped with a series of filters through which it circulates the air in your home. 

Some air purifiers can rid your environment of up to 99.97 percent of pollutants that are at least 0.3 microns in size. Others are also equipped with an Activated Carbon Filter. This filter can eliminate damp and stuffy smells that result from mold. 

There are several types of air purifiers that are available on the market today, including:

  • Filter air purifiers – These are equipped with HEPA or ULPA filters, which cycle air and trap pollutants.
  • Ionizing air purifiers – A powerful electric field gathers and settles oppositely charged particles out of the air. 
  • Adsorbents – Adsorbent material is used to neutralize fumes, odors, and chemicals present in the air. 

The function of a dehumidifier, on the other hand, is to control the moisture levels in your home’s air. Moisture is the primary cause of mold, especially in basements and small rooms. A dehumidifier sucks moisture from the air and collects it inside an in-built bucket. 

Unlike an air purifier, a dehumidifier doesn’t get rid of pollutant particles from the air. Nonetheless, reduced humidity can help minimize dampness and mold-induced musty smells in your space. Dehumidifiers are also effective in getting rid of dust mites and keeping your home cool.

There are two major types of dehumidifiers available on the market:

  • Refrigerant Dehumidifier – These work by condensing moisture out of the air.
  • Desiccant Dehumidifier – Air is passed through a rotor containing adsorbent desiccant material. After removing water from the air, dry air is blown into the room to encourage drying. 

Regardless of the type of dehumidifier you choose, both are effective in maintaining healthy levels of humidity in your environment. This protects you from the health effects of excess humidity like mold-induced allergies. 

Air Purifier vs. dehumidifier for mold – which is best?

Mold is the major culprit when you notice musty, milder odors in your home. These organisms need water to thrive. So, when they begin to develop and emit unpleasant odors, there’s a high chance there’s an increase in the amount of moisture in your home, room, or basement. 

An air purifier can help reduce the smell. However, the most effective way to get rid of that smell is to remove the excess moisture also. That means a dehumidifier would be a better choice for mold removal.  

Several other factors can help you decide on whether to get an air purifier or a dehumidifier. An air purifier would be a great choice in the following situations:

  • You or a family member has respiratory issues like asthma
  • You have animal allergies and want to reduce pet dander in your environment
  • You want to create a healthier living space by reducing dust
  • You want to neutralize unpleasant odors in your home

Conversely, consider getting a dehumidifier in the following situations:

  • Excess humidity is worsening your respiratory problem
  • You want to neutralize musty smell in your space
  • You want to get rid of dust mites
  • You want to keep your home cool without using the air conditioner

Air purifiers and dehumidifiers work to complement each other. However, they are not interchangeable. An air purifier can’t control the amount of moisture in your home’s air, while a dehumidifier can’t get rid of pollutants from the air. However, there is no reason you can’t use both at the same time. There are even combo-devices available, though in most cases separate units cost less.

Personally, I have always been fascinated with home items. I’ve learned long ago that when buying these products, there needs to be a balance between functionality and creativity. Otherwise, they get old and boring, and I don’t get to use them as much.
