How to remove mold and choose a dehumidifier for damp room?« Back to Previous Page

My kids have been coughing and I suspect it’s from the black spots I just found behind our wardrobe in the master bedroom. We're in a villa in Jumeirah, and even with the AC running, the room feels damp since the weather got humid a few weeks ago. What's the best way to treat this and what kind of dehumidifier should I get to stop it from coming back?

Based on your description, this is a classic case of condensation-induced mold growth, very common in Dubai villas during the humid summer months. The black spots are likely Aspergillus or Cladosporium, which can absolutely cause respiratory irritation and coughing in children.

First, do not attempt to clean this yourself with bleach. This can aerosolize the spores and worsen the air quality. For a small area (under 1 sqm), you can carefully wipe it with a microfiber cloth dampened with a dedicated EPA-approved fungicide. However, given the health symptoms and the hidden location (behind a wardrobe is a major red flag for a larger problem), a professional inspection is strongly recommended. We use thermal imaging and moisture meters to find the exact moisture source and assess the full extent behind walls.

For the dehumidifier, given the room size and UAE humidity, you need a high-capacity unit. Look for a desiccant dehumidifier—they perform far better than refrigerant models in our climate, especially in AC-cooled spaces. The capacity should be at least 20-25 liters per day for a master bedroom. Ensure it has a built-in hygrometer and auto-shutoff to maintain humidity between 45-55%, the range that inhibits mold growth.

Ultimately, the dehumidifier is a solution for the ambient humidity, but the immediate mold issue needs proper assessment and remediation to protect your family's health. We offer free, no-obligation inspections to give you a clear path forward.

For a proper assessment, please call us at 800-MOLDS or 800-66537 to schedule an inspection. We can identify the exact species and recommend the correct remediation protocol.
