Why won't dehumidifier eliminate damp smell?« Back to Previous Page

After the rain last month, I noticed a damp musty smell lingering in my bedroom closet. Despite turning on the dehumidifier and keeping windows slightly open during sunny spells, the odor persists. I suspect it might be due to condensation building up behind the wall. How can I effectively prevent this from happening or recurring?

Dehumidifiers can be effective at reducing moisture levels and minimizing damp smells but they may not always eliminate them completely. In Dubai/UAE, the climate is typically warm and humid, especially during the summer months. This makes it challenging to solely rely on dehumidifiers for eliminating a musty smell.

In your case, it sounds like there might be an issue with condensation building up behind walls. This can often occur when moisture from outside gets trapped within walls or cavities in your home. Turning on the dehumidifier and keeping windows open during sunny spells are good temporary measures but may not address the root cause.

To effectively prevent this, you should consider a professional inspection of your house. In Dubai/UAE, regulations require buildings to be designed with proper ventilation systems that can handle high humidity levels. However, over time, these systems might need maintenance or could have issues that aren't immediately apparent.

Here are some steps you can take:
1. Inspect the affected area for any signs of water damage or leaks.
2. Ensure your building has adequate ventilation. This includes checking all exhaust fans in bathrooms and kitchens as well as ensuring there's a proper air flow through the walls and ceilings.
3. Use moisture barriers when constructing or renovating to prevent water penetration into wall cavities.
4. Consider installing a whole-house dehumidification system, which can be more effective at lowering overall humidity levels.
