Black mold in bedroom: health risk and who to fix?« Back to Previous Page

That black patch is likely Stachybotrys, commonly called "black mold," which thrives in the consistently damp conditions created by an AC leak. In Dubai's high humidity, this is a frequent issue where condensation or leaks occur.

The persistent dry cough and congestion you both are experiencing are classic symptoms of prolonged exposure to mold spores. While not everyone reacts, it can significantly irritate the respiratory system and worsen allergies. For individuals with asthma or compromised immunity, the risk is higher.

This is not just a job for building maintenance. They can fix the AC leak to stop the moisture source, which is the critical first step. However, the existing mold growth itself requires proper remediation. Simply wiping it can aerosolize harmful spores throughout the room.

For a patch larger than a square foot, or due to the health symptoms, a professional assessment is recommended. Remediation involves containing the area, using HEPA filtration to capture spores, safely removing the contaminated material, and verifying removal with post-remediation testing. In the UAE, look for providers who can document the process with before-and-after lab analysis to confirm the environment is safe.
