Best HEPA Air Purifiers for Mold Spores

For homeowners, mold spores are such a nuisance. I wonder what can be compared to the frustration a homeowner has to go through after seeing mold spores ruin the look of their house interior. While there are different methods to deal with the mold spore issue, using a HEPA air purifier is one of the most affordable ones. In fact, this is one of the best methods to prevent this problem from occurring in the first place. That’s why I have brought together a list of the best HEPA air purifiers for mold spores. 

For those who don’t have a clear idea what a HEPA air purifier actually is, these are specialized air purifiers that come with HEPA filters. HEPA stands for High Efficiency Particulate Air. HEPA filters have to meet specific standards of efficiency. The most significant of those standards is, a HEPA filter must remove over 99.97% of particles with a diameter equal to or less than 0.3 μm from air passed through them. 

Well, you don’t need to memorize all the scientific jargons, as the main priority of this post is to recommend you some of the best HEPA air purifiers for mold spores. I have researched hundreds of such air purifiers, and made a short list based on efficiency, cost effectiveness, longevity, and real user reviews. 



Guardian Technologies is one of the best air purifier brands out there, and the GERMGUARDIAN AC4825 is another great example of their competence. People who are looking for an affordable solution to mold problems, should definitely give it a go. Regardless of being a budget option, it comes with a true HEPA filter that meets very high quality standards. 

Now the question is, how effective this one is going to be for mold control. Well, activated carbon filters installed in the AC4825 will surely help with reducing the irritating odor of mold. This means, it’s a great choice for houses that are located in areas with a lot of moisture in the air. Moreover, it also kills airborne mold spores, not to mention viruses and bacteria as well. 

The only caveat with this product is that it does not come with any other additional filters and relies heavily on the 3-stage air cleaning system of the HEPA filter. If mold control is your main priority, then that should not be a concern for you by any means.


  • Great value for money product
  • Energy efficient
  • Easily takes care of mold and viruses 
  • Good quality filtration system
  • Product from a reputed brand


  • Does not have additional filters
  • Not suitable for large rooms



The next entry into my list is another affordable, but all-round air purifier. Like the previous one, it also comes with a True HEPA Filter that easily deals with mold, fungi, virus, pollen, and allergen particles. It also comes with additional filters that keep your room’s air free from large dust, hair, and fur. The cherry on the top is the ionizer that neutralizes almost all kinds of air pollutants. 

Last but not the least, you will also get an activated carbon filter in the APH260, which includes Cold catalysts, nano material, molecular sieve carbon, and photo catalyst. Harmful chemicals and smoke will not be able to affect your room’s air due to this addition. 

If your room size is not too big, then you will also like the Smart Sensor in it. It will give you details about the quality of air in your room. It is great to know what you are breathing, isn’t it? 


  • Top notch filtration system
  • Lightweight
  • Smart Sensor
  • Silent operation
  • Affordable price tag


  • Sensor range is very low



I am not done with great budget picks yet, and InvisiClean Aura II is arguably the best budget option out there. Despite coming at a really cheap price, this HEPA air purifier comes with both activated Carbon filter and H13 True HEPA filter. It is a nemesis of mold, viruses, and mildew, and you will be surprised how effective its filtration system is for the price. 

You can also use a separate pre-filter to get rid of large particles from your room’s air. It contains an ionizer as well, in order to neutralize air pollutants. When the room doesn’t have large particles, you can simply switch it off. 

The InvisiClean Aura II follows a 5-stage air filtration system, heavily reducing the chances of mold spores to affect your health and your house. It kills mold spores with UV light, one of the most effective methods to do so. 


  • Powerful fan
  • Additional filters
  • 5-stage air filtration
  • UV light
  • Best for the buck


  • Can be a bit too noisy for some people



ACCO Brands Corporation is one of the most reputable home and office products manufacturers in the US. They are well known for their great quality flagship home improvement products, and the TruSens Z-3000 is no different. This is the best purifier ever made by the company, and it comes with PureDirect technology that you won’t find in filters from other companies. 

Apart from the True HEPA filter, the Z-3000 also features an activated carbon filter to remove specific harmful gases and odors. It is also capable of getting rid of Volatile Organic Compounds. And mold spores? The HEPA filter is powerful enough to take care of it! 

The most attractive feature of this HEPA air purifier is the range it covers. The TruSens Z-300 covers up to 750 sq ft, almost the size of an apartment. Buying this one means you won’t have to purchase any other air purifier for your house, as it will cover the entire house, unless you live in a mansion though. You can even enjoy fresh air at night without any irritation, as it has a dedicated sleep mode which makes the purifier almost silent. You are also getting a remote air sensor known as SensorPoD with the Z-3000.

Rabbit Air MinusA2

Rabbit Air MinusA2

If one has to make a shortlist of leading air purifier companies, they will not be able to make one without Rabbit Air. Since 2004, Rabbit Air has been producing some of the best quality air purifiers out there. The MinusA2 too is a high-end air purifier with a plethora of smart features. 

The design and look of the MinusA2 will tell you that it is a premium product. It has five filters, including an advanced BioGS HEPA Filter. As you know, the HEPA filter’s main responsibility is to keep micro particles away from your room’s air. The other four filters deal with large particles, mold, dust, toxins, germs, odor, smoke, and chemical vapors. These five filters are supported by Ion generators as well, making a six layered filtration process. 

MinusA2 is remarkable in terms of coverage, as it’s bigger edition can cover up to 815 sq ft, while the smaller one can cover up to 700 sq ft. It eliminates the need to install any other air purifiers if you live in a moderately sized house. 

One of the premium features of Rabbit Air’s air purifiers is that they come with a specialized Quiet Mode, which takes advantage of a brushless direct current motor technology to run the fan quietly. You won’t even realize that your air purifier is on because it would hardly make any noise with the Quiet Mode switched on.

How to Choose the Best HEPA Air Purifier for Mold Spores

When it comes to choosing air purifiers, you must be very careful. In fact, your air purifier will control what goes inside your lungs, and a bad quality product can make a mess of your health. While mold spores are not that much harmful for your health, you still need to get rid of them. And it’s not the only job of an air purifier to control mold, but to keep the air clean from viruses, bacteria, fume, smoke, micro particles, dust, and so on. 

Here are the key things to remember while choosing a HEPA air purifier for mold spores. 

  • It might sound a bit stupid, but be sure that the air purifier includes a HEPA filter. If you are willing to buy a purifier for mold spores control, then it must come with a HEPA purifier. The filter should be able to prevent 99.97% of micro particles with a diameter equal to or less than 0.3 μm, otherwise it can’t be called a HEPA purifier. 
  • The number of filters is another very important benchmark of the quality of an air purifier. Other than the HEPA filter, a pre-filter, a carbon filter, and a UV-C light filter are great to have in an air purifier. And the point is, you will find air purifiers with all these filters for a very decent price. So why not go for more? 
  • The number of filtration layers is as important as the number of filters. Some confuse these two as the same thing, but they are different. Some air purifiers come with ion generators, adding one extra layer of filtration over the filters. Ion generators are not in fact filters, but they do add an extra layer, clear? 
  • Energy consumption is a big concern while choosing something like an air purifier. You would not want to get a heart attack after receiving the electricity bill right after the month you have installed your new fancy HEPA air purifier, right? Choose an energy efficient option. 
  • You would want to install a HEPA air purifier in your room to get more comfort, not irritation. That’s why you need to be sure how much sound an air purifier makes before purchasing it. If you buy the wrong one, you might not be able to enjoy it at all because of too much noise. On the other hand, buying one with an extended quiet mode will even allow you to turn the purifier on while sleeping.
