Only an air purifier with a HEPA filter will remove more than 99 or 97 percent of mold spores from the air. Mold spores are larger than the particles that HEPA filters are designed to capture; however, an air purifier alone isn't enough to prevent mold growth. Overall, the best air purifier for mold is the Levoit Core 300 with powerful filtration. It is a compact air purifier that can draw air from any direction and has an easy-to-use screen that controls functions such as the three fan speeds.
One of the fan speeds allows the purifier's silent mode, which reduces noise to 24 dbs, as if someone were whispering to you. While a good air purifier can filter mold spores in the air, it's important to combat mold at its source. Breathing in black mold is especially dangerous for asthmatics, as even non-toxic molds can cause asthma attacks. All black mold has the potential to trigger allergy symptoms in people with allergies, but not all black mold is toxic.
While the health effects of exposure to toxic black mold are widely debated, there is sufficient evidence that black mold in the home endangers all occupants. Mold spores are always present, but air purifiers with HEPA filters can remove them from the air and improve air quality. In independent laboratory tests, the filter was found to effectively eliminate 99.9% of airborne mold spores after two hours of operation. That said, some mold species can create microscopic toxins called mycotoxins, which are even smaller than mold spores.
If you suspect that there is black mold (or any other mold growth) in your home, you don't have to resign yourself to breathing in spores or other dangerous byproducts. Considering the complexity of each person's immune response to mold antigens and the variation in the byproducts of a particular group of molds, it's easy to understand why the same variety can produce very different health effects. One of the best things you can do to protect yourself from inhaling mold is to use a high-quality air purifier for mold. However, there are some indoor molds that pose significant health risks, and black mold is one of them.
If you find black mold, an air purifier can capture, reduce and destroy the mold particles that are released into the air when you remove it. If all the material that has touched the mold is not removed and the moisture problem is not solved, rapid recolonization will occur. While most air purifiers don't get rid of mold or mildew that is already growing on surfaces, these machines help prevent mold spores from falling in the first place. Eliminating mold from your living and working environment is generally the best way to control symptoms.
It takes time to determine if there is black mold in your home, and an air purifier can reduce mold particles in the air while you gather more information.
