Molds can be found everywhere, but they are also hard to spot on the surface. While there are some molds that are totally harmless, all kinds of molds can be quite dangerous if left naturally growing inside your home. Thankfully, there are ways to make sure we are not inhaling those nasty spores they throw up in the air.
While mold reaction can vary depending on the individual, accidentally inhaling abnormally high quantities of mold spores may cause some respiratory problems which can trigger asthma, sinusitis, or in some worst cases, may cause mycotoxin poisoning which can eventually lead to death.
To make sure your house is guarded against these harmful spores, many air purifiers in the market are designed specifically to filter out these microscopic air impurities. Today, we will be listing some of the most popular of these said devices.

Air Purifiers for Mold Spores - Buying Guide
What is Mold?
Mold is a type of fungus that thrives on moisture and reproduces through spores that travel through the air. Mold spores can range between 3 to 40 microns (to put that in perspective, a human hair is 100 to 150 microns) so they are really hard to spot on. It can grow in a moist area of your house, like windows, ceiling, carpets, and even books. So it’s always advisable to fix any water leak to stop it from reproducing itself.
Buying a specialized air purifier for mold can also help you if you have existing mold issues inside your house.
How does Mold impact human health?
As mentioned above, not all molds are harmful to humans, however, if it is left growing naturally inside your home, this becomes a huge problem. Mold throw spores in the air to reproduce which, if accidentally inhaled in abnormal amounts, can lead to serious respiratory problems, including death by mycotoxin poisoning.
Mold exposure issues can vary between different people. Sensitive people with existing health issues like allergies, asthma, and a compromised immune system may experience an inflammatory and toxic response to mold spores. If not, it can trigger the said diseases, and cause more respiratory issues like hypersensitivity pneumonitis, allergic alveolitis, chronic rhinosinusitis, and allergic fungal sinusitis.
Some of the more harmful molds also produce mycotoxins which spread through spores. If accidentally inhaled in large quantities, this could lead to death.
Factors to consider when buying the best air purifier for mold
1. Maximum area coverage
The first thing you should consider when buying an air purifier is the maximum area coverage it can clean up. Your room should at least be below the minimum area of coverage of the considered air purifier, or you can purchase two of them to cover the entire area.
One of the air purifiers we listed here, for example, the Alen Breathesmart Classic Air Purifier can cover a whooping 1,100 sq. ft. of the room area. That means, it should effectively clean and circulate the air in an area that is below 1,100 sq. ft.
2. Type of particle filter
Each air purifier contains a filter that will be able to capture pollutants at the microscopic level. However, the effectiveness of the filtration depends on what type of filter the air purifier has. If the primary concern is all about pet hair, and pet dander, options like true HEPA filters will be able to capture fine air pollutants down to 0.3 microns.
This is because, to meet the HEPA standard, a filter must remove at least 99.97% or more of particles that are as small as 0.3 microns in diameter. In perspective, the size of human hair is approximately 80 to 100 microns in diameter. That is how small a HEPA filter should be able to capture.
Beware of air purifiers with HEPA-type, and HEPA-like filters as these are not true HEPA. They will not be able to remove 99.97% of particles that are 0.3 microns in diameter and is only used as a term to confuse consumers to buy low-quality air purifiers. However, if your concern is not about an allergen, and just some larger than 0.3 microns dust particles in the air, these options will work just fine too. But don’t expect it to release a fine purified air as with the true HEPA.
3. Optional ionizer
None, but only one of the products on this list includes an ion generator, the SilverOnyx Air Purifier.
While not that big of a requirement, having a negative ion generator in the air purifier can become one of the major considerations when purchasing an air purifier that is designed specifically to eliminate mold and bacteria in the air.
Negative ions exist in nature in many places after some natural phenomenon like discharges of electricity after a thunderclap, or wherever water collides with itself like a waterfall or ocean shore. It can also be found on ultraviolet (UV) rays from the sun or produced as a normal growth process of many plants.
Researchers believe that exposure to negative ions can reduce symptoms of depression and anxiety for some people, promote antimicrobial activity, and improve breathing and blood pressure.
4. Recurring cost
Air purifiers are known as an expensive investment, and expenses continue even after the purchase. To make sure that the air purifier works efficiently and effectively as it was first bought, you should also be ready to spend money on filter replacement. However, some air purifiers come with a washable filter (usually odor filters) that you can just wash and are ready to use again as it is. If recurring cost is a big issue for you, look for air purifiers that come with a washable filter. This will help you in keeping the running cost in check.
Finally, the warranty is also a big factor in purchasing air purifiers. As you can tell, air purifiers are an expensive home investment. With that said, you expect to get the most out of your money with the device by using it for a long period.
If you are purchasing an air purifier, also look for how long the manufacturer will be able to provide free service to your device. In this list, for example, the highest number of warranty goes on for three long years. That is three years of manufacturer support if you have any problems with your air purifier within the time range.
An air purifier is an expensive investment, but it is also a worthy one. Mold is ubiquitous, they are everywhere. The last thing you want them to thrive in is inside your home, and they’re nasty. It can cause many health issues especially to kids and sensitive individuals. It may even cause death if accidentally inhaled in large quantities.
Specialized air purifiers can help eliminate this issue. Not only that they remove mold and bacteria from the air, they also make sure that you only inhale fresh and filtered air that is free from allergens.
Hopefully, our list helps you decide which product is the best for your family.
