Mold spores remain in the air for an indefinite period of time. It is important to recognize that if there is a humid area unattended for more than 24 hours, there is a great chance that mold will become infected and spores suspended in the air will begin to accumulate throughout the room. While it's not feasible to maintain a completely sterile environment free of mold spores, there are ways to significantly reduce the number of mold spores in your home's air. To completely remove all mold spores from the air, you will have to be very careful and thorough.
To completely eradicate any mold spores that are present in the air, you'll first have to attack the source of the mold.

Dehumidifiers don't eliminate or eliminate mold spores that are already in the air, but they can help prevent them from growing and spreading indoors by keeping relative humidity levels low. If you've discovered that you have mold growing anywhere in your home, you're understandably concerned about mold spores found in the air. Bleach is a biocidal product that can kill mold on hard, non-porous surfaces, but bleach doesn't kill mold spores in the air. Air purifiers and air purifiers are devices that remove air pollutants from the air in your home, including mold spores.
Mold spores are small reproductive fungal cells that float in the air like microscopic particles that seek a favorable environment to establish new mold colonies.
