Is black mold causing our respiratory issues?« Back to Previous Page

Yes, the black mold behind your sofa is very likely the cause of your family's persistent coughing and allergy flare-ups. In Dubai's high humidity, especially in older Deira buildings, this is a common scenario. Mold releases spores and microbial volatile organic compounds (mVOCs) that are direct irritants to the respiratory system, often presenting exactly as you've described: chronic coughing, congestion, and worsened allergies.

The specific danger depends on the mold species, which can only be confirmed by a professional lab test. However, any significant patch of mold in a living space, particularly black mold, should be treated as a health risk, especially for children. The continuous exposure from your AC system circulating air past it is the most probable culprit for your symptoms lasting a month.

You need a professional inspection. Do not attempt to remove it yourself, as disturbing it will aerosolize a massive amount of spores throughout your home. A certified inspector will assess the full extent of the growth, identify the moisture source (like the AC leak you suspect), and take air and surface samples for lab analysis to determine the species and concentration. This evidence is crucial for building management if the leak originates from a central system.

For remediation, the AC unit and ductwork will likely need cleaning by a company that uses containment barriers and HEPA filtration to prevent cross-contamination, followed by fixing the leak. After remediation, a clearance test from an independent lab is the only way to verify the air quality is safe again.
