There are many types of air purifiers and some work better than others for microbes such as mold.

Are air filters the same as air purifiers?

Air filters only clean the larger particles in the air such as dust and dander. However, air purifiers will sanitize the air using ozone, heat, negative ions, or UV and UV-c light. Most air purifiers also have a filter to remove those large particles. However, some air filters don’t have a purifying mechanism and thus just filter the air of large particles like dust.

Are there any mold-removing air purifiers?

No air filter or purifier can remove mold that has settled into household items like walls, kitchens, bathrooms or furniture. This means that an air purifier doesn’t work on its own to fix a mold issue. However, once mold has been cleaned and removed from the house, an air purifier can prevent mold from returning. Air purifiers can help remove spores and some models can actually burn up the spores completely.

air purifier turned on - homebioticDo I Need A HEPA Filter For Mold?

A HEPA filter is an efficient filtration system that can help reduce mold spores circulating in the air. HEPA stands for high-efficiency particulate arresting or high-efficiency particulate air. A true HEPA filter is considered the best air purifier on the market. It is also a good air purifier for mold. However, it won’t kill mold so you may need an air purifier that also contains a strong UV light or UV-c light. A UV light takes things one step further and can literally fry mold spores.

What is a true HEPA filter?

There are HEPA-type filters and then true HEPA filters. The main difference is in the efficiency of the filtration system. A true HEPA filter works almost 100% and can grab extremely small particles that a HEPA-type filter can’t grab.

What is the best air purifier for mold and mildew?

The best air purifier for mold in your house is a true HEPA filter with a UV-c light. Not only can this filter trap spores and remove them from the air, but it can also kill off spores so they don’t lodge in air purifier filters. Unfortunately, mold can damage filters if too many spores build up inside the HEPA filter system. Having a HEPA filter with UV-c light is the best solution as it will reduce mold spores and kill them.

Mildew is generally less harmful than mold even though it is a type of fungi as well. It usually grows on wet surfaces like kitchen and bathroom tiles and in moist corners where water builds up and remains. In this case, an air purifier can help with circulating spores but can’t actually remove mildew. Removing mildew is easy and requires a simple wipe using hydrogen peroxide or just vinegar and water.

dehumidifier - homebioticWhat’s Better For Mold, An Air Purifier, Or A Dehumidifier?

Air purifiers and dehumidifiers are two very different pieces of equipment. Often you can find units that have both an air purifier and a dehumidifier built-in. But they are also sold separately. An air purifier cleans the air whereas a dehumidifier removes excess moisture from the air. Both mechanisms are important in treating and preventing mold.

Mold needs the following circumstances in order to grow: food, moisture, and free space without competition. Mold grows by emitting spores into the air that settle on surfaces and multiply. Air purifiers can help grab mold spores out of the air before they settle anywhere. As we said above, it’s not the only way to prevent mold, but it certainly helps when the problem is simple or in a preventative manner. Dehumidifiers help reduce mold by taking excess water out of the air and surrounding items. This robs mold spores of the moisture that they need in order to grow. So as you can see, a combination of both an air purifier and dehumidifier can really help reduce and prevent mold.

How Important are air purifiers in reducing or preventing mold growth?

Air purifiers, especially those with a UV light or UV-c light, can be invaluable in reducing or preventing mold. However, one should never rely solely on air purifier units. Instead, adopt a more broad approach by preventing all the conditions necessary for mold to grow. Remember that mold needs space, food, and moisture so anything that can be done to prevent those conditions will help reduce and prevent mold and mold spores. Some ways to do this are: use fans, open windows, keep air circulating in the home, fix water leaks, prevent water build up, and remove food sources around moist areas. All of these measures plus the addition of an air purifier will help reduce and prevent mold spores and mold growth.

happy family - Do Air Purifiers Help With Mold Growth?Conclusion

Air purifiers can be a very beneficial investment when you want to reduce or prevent mold issues in your home. Although they can’t fix an established mold problem, they can certainly help with removing and reducing mold spores and improving air quality. Be sure to find air purifier products that have a UV or UV-c light as this is the best way to actually kill mold spores not just trap them in the filter. Remember that filters can get overrun with mold too which is why UV light is more effective.

In short, air purifiers can be a really helpful part in preventing mold growth and mold spores. If you’ve ever had a mold issue or you have family members with mold-related allergies or illnesses, it would be very beneficial to do some market research and get the right air purifier for your home.
