Is Dubai AC mold causing our cough and headaches?« Back to Previous Page

Yes, the black mold from your AC leak is a very likely cause of your persistent dry cough and headaches. In Dubai's climate, AC units that leak create a constant source of moisture, which is the primary condition mold needs to grow. The airborne spores from that patch can easily circulate in your bedroom air, leading to the irritation and inflammation you're both experiencing.

For a situation like this—visible growth with health symptoms—professional remediation is strongly advised, not a DIY cleaning. Disturbing the mold yourself can release a large number of spores and make symptoms worse. The safest approach is to first have a certified inspector conduct a proper assessment. They can identify the exact species (like Stachybotrys, the "black mold" often associated with toxins, or another common type like Aspergillus) and the full extent of the contamination, which often spreads behind walls from a leak.

In Dubai, look for a company that follows IICRC S520 standards for mold remediation. The process should include sealing off the area, using HEPA filtration to capture airborne spores, safely removing the contaminated materials, and then treating the area to prevent regrowth. Crucially, the job isn't complete until a post-remediation verification test, typically done by a third-party lab, confirms the spore count inside the treated area is lower than the outdoor baseline. This is the only way to verify the cleanup was truly effective and your bedroom is safe to reoccupy.
