If you just stumbled on this post, then a brief background will help. Molds are certain fungal species that thrive on moisture. They attach themselves to organisms, foods or just any surface that is damp or wet.

However, they are also big occupants of the air, increasing our exposure to them. Although harmless in small quantities, mold can have a harmful effect on your health if you’re exposed to large quantities over a period of time.

To get rid of mold, you need the best air purifier for mold and that is what this post wants to show you.

We have put together the 5 best purifiers for mold you can find on the market. But before that, we’ll show you how to choose an air purifier for mold based on your unique needs and preferences.

Top Air Purifiers for Mold: By Best Performing Feature

Buyer’s Guide: Critical Factors to Consider to Select the Best Air Purifier for Mold

1. Coverage

The Coverage of the air Purifier will determine how much of your room, home or office it’ll cover and clean. It is quite simple; if you have a large room in excess of 500 square feet, you should get an air purifier that can cover that much space and more.

But it’s not just about coverage; the air delivery rate is also important here. How much of that space can be cleaned within 30 minutes or an hour and how much air exchange can be done in a day?

These are very important boxes to tick before you settle for an air purifier for mold.

2. Type of Filter

It is a given that the type of filter an air purifier has determines what it’ll be used for. Let’s see a few of them;


HEPA means High Efficiency Particulate Air. It is a type of filter that is great at capturing and eliminating airborne particles, dust, dander and pollen.

When it comes to mold spores, the HEPA filter is also very effective and it is one that you should look out for. Specifically, look out for the “True HEPA” status if you desire more effectiveness.

Activated Carbon:

This is another filter that is designed to take care of odors from VOCs and other gases.

Although molds are particles, they also let out some irritating odor and Activated Carbon filters can help eliminate those.


Ionizers work by releasing negatively charged ions that attach to air particles, making them too heavy to float and dropping them to the ground or sticking them on walls.

The downside is that while it may prevent mold spores from floating, it doesn’t exactly eliminate them. There is also the concern of ozone release and irritation.


UV-C light is another great option for eliminating viruses and germs. However, the issue of exposure to UV light is a serious concern.

3. Smart Technology

Although not specific to mold spores, having an air purifier that conforms to growing technology will make life easy for you. Flexibility, comfort and convenience come with having extra high-tech features.

Whether it’s app-controlled which offers you the freedom to control it remotely or sensor technology, you can be sure of getting much more value from a smart air purifier for mold.

4. Size

The dimensions of the air purifier are not just a factor to consider but a necessity as well. You don’t want to buy an air purifier that takes up all the space in your room, do you?

Although it is common to find more fan power and efficiency in bigger purifiers, it is not always the case. Try and look out for portability without compromising the efficiency of the device.

You need to be able to stash it in a corner of the room without causing any inconvenience or disruption of movement in your home or office.

5. Noise Level

Noise is measured in decibels. As is the case, the higher the fan speed, the louder the noise. When you shop for an air purifier for mold, be sure to look out for a product that comes with minimal noise level.

The best in the noise category would usually emit between 20 and 50 dbs from the lowest fan speed to the highest fan speed in terms of noise.

A low-noise air purifier will ensure it doesn’t cause a nuisance during operation. This is also important for night use when residents need to sleep.

Thankfully, most air purifiers for mold have a sleep mode feature.

6. Air Quality Indicator

Having an air quality monitoring feature and indicator means you’ll be able to tell at every point how clean or polluted the air in your home is.

This is important because it will inform decisions like whether you need to increase or reduce the fan speed and so on.

Usually, you’ll find a LED feature of different colors like red and green to indicate clean and dirty, or to alert you when a fan increase is needed.
