Here are some interesting facts about mold. Mold size can be as small as 1 micron (around bacteria size) to as big as a single hair at 80 microns. Because of the size variation, we will unlikely to see any airborne mold through our naked eyes and inhale straight to it. Migraine, Autoimmune disease, Heart inflammation, Respiratory tract damage, and Infertility is some of the known mold diseases. Fortunately, HEPA air purifier would be able to tackle most part of this issue. A HEPA filter is tested and certified to capture allergens as small as 0.3 microns at 99.97% efficiency.
Removing Mold With Air Purifiers
Air purifier does work with mold even though it can only target microbes that are airborne. When the airborne mold spores are drawn into the filtration, the HEPA filter will capture the microbes from proceeding. All the incoming allergens will be safety trapped inside the fibers and the air purifier will only release purified air out. If the air purifier comes with UV-light, it can destroy the microorganisms permanently.
With less mold spore in the air, there is less chance the mold would be able to spread across the room and grow. You will see less mold infestation on the wall, ceiling, shelf, and even settle on the floor. Your mold symptoms will also gradually go away as the exposure is lessened.
Air Purifiers Limitation
An air purifier can get rid of airborne mold but it cannot touch any mold or microbes that are settled on the ground. This includes mold that is stuck on the wall, wood, upholstery or ceiling board. When the environment is damp enough for mold to thrive, it will continue to do so and the spreading never ends. To address the root cause, you will need a dehumidifier to remove the moisture in a room. Without the ideal humidity level, the mold will not survive let alone grow. You can learn more about the differences between air purifier and dehumidifier here.
Another common air purifier problem is mold reproduction in the filter. Mold and other microbes that are trapped in the filter will reproduce if the humidity is just right. When the “new” spores are ready to spread, the air purifier will unintentionally help circulate the mold across the room. This is the reverse effect on what an air purifier suppose to do. To counter this problem, make sure the HEPA filter comes with an antimicrobial treatment that will halt any trapped mold from growth.
What Air Purifier Is Best For Mold?
Air purifiers are good at removing airborne microbes. That is what it is meant to do. After some intensive comparison between many excellent HEPA air purifiers, we handpicked the best of the best.
- Rabbit Air MinusA2
- IQAir HealthPro Plus
- Winix HR1000
- Honeywell HPA300
- Airmega 400
All of the above air purifiers used a genuine HEPA filter with at least 99.97% filtration efficiency. Airflow performance must be decent to cover the entire room from the airborne mold. Few of them even have an antimicrobial coating that prevents microbes from growth. To learn more on the above picks, visit our best air purifier for mold page.
