Is black mold causing our persistent sickness?« Back to Previous Page

Yes, the black mold behind your bed is very likely causing the persistent coughing and allergy symptoms you're describing. In Dubai's humid climate, AC condensation leaks are a common source of mold growth, particularly in areas with poor airflow like behind furniture. The constant exposure to mold spores, especially in your bedroom over many hours of sleep, directly irritates the respiratory system and can trigger the exact reactions you're experiencing.

For a growth of that size and given the health impact, professional remediation is strongly advised over a DIY approach. The process must address both the visible mold and the hidden moisture source—in this case, the AC condensation line or drain pan issue. In the UAE, reputable remediation companies follow standards like the IICRC S520 for mold removal, which includes containment of the area to prevent spores from spreading throughout your apartment, safe removal of contaminated materials, and HEPA vacuuming to clear the air.

After removal, a diagnostic test from an independent microbiology lab is the only way to verify the spore count has returned to a safe, background level. To prevent recurrence, have an HVAC technician service the AC unit to fix the condensation leak and consider using a dehumidifier, as Dubai's high humidity provides the constant moisture mold needs to grow.
