How to stop closet mositure and mold in humid bedroom?« Back to Previous Page

Our master bedroom closet, which is on an interior wall, has a faint damp smell that's getting stronger. I just pulled out my winter clothes from the back and found several jumpers with small black speckles on them. We run the AC constantly, but the room always feels a bit more humid than the rest of the apartment in Marina. Besides a dehumidifier, what's the most effective way to stop this moisture from building up and prevent the mold from coming back?

The damp smell and visible mold on clothes indicate a consistent moisture issue, often from high humidity condensing in cooler, stagnant areas. Since you're in Marina with constant AC, the problem is likely insufficient airflow and temperature differences causing condensation inside the closet.

First, improve air circulation. Leave the closet doors slightly ajar and ensure no furniture is blocking the AC vent in the bedroom. If the vent is elsewhere, a small battery-operated fan inside the closet can significantly reduce stagnant, humid air. Second, check the AC's drainage line and drip pan; a clog or malfunction can cause excess humidity. Setting your AC to a slightly lower temperature, around 22-23°C, can also help it remove more moisture from the air.

For the mold, discard any heavily affected porous items like paper or cardboard boxes. Wash moldy clothes with a disinfecting laundry additive. Wipe down all closet surfaces with a solution of detergent and water, not bleach, as bleach doesn't kill mold roots and can worsen indoor air quality.

Given the persistent smell and recurrence, a professional inspection is advised to rule out hidden issues, like a small plumbing leak in the wall or compromised AC insulation, which are common in Dubai's climate. They can use moisture meters and thermal cameras to find the exact condensation source. For confirmed growth, a targeted hygienization treatment by a company with a microbiology lab ensures the mold is properly identified and addressed at its source.
