Is high humidity causing a musty smell?« Back to Previous Page

After the heavy rains last month, I noticed a persistent dampness in my living room. The humidity feels pretty high even with the AC running, and there’s this slight musty smell that's driving me crazy. Have you dealt with something like this before? How did you go about solving it?

Yes, high humidity can certainly be causing the musty smell you're experiencing. In the UAE, especially in Dubai where we experience significant temperature fluctuations and occasional heavy rains, maintaining indoor air quality is critical to prevent such issues.

The presence of moisture coupled with high humidity levels often leads to the growth of mold and mildew. These microorganisms thrive in environments that are damp or humid, making your living room a potential breeding ground for them. The musty smell you're describing is typically associated with organic matter decomposing due to mold growth.

To address this issue effectively, it's advisable to conduct a thorough inspection by professionals who specialize in indoor environmental quality and remediation, such as those from Saniservice (you can reach out at 800-MOLDS or 800-66537 for assistance). They will be able to assess the extent of moisture damage and provide targeted solutions.

Some practical steps you could take while awaiting professional advice include:

1. Use a dehumidifier: This is crucial in mitigating high humidity levels, especially during rainy periods or when you notice increased dampness. Ensure that your unit is capable of removing at least 50 pints per day for a large room like your living area.

2. Increase ventilation: Open windows if possible to allow air circulation and reduce moisture build-up. Using exhaust fans in bathrooms and kitchens can also help remove excess humidity.

3. Check for water leaks: Inspect your property for any hidden or visible sources of moisture. Leaks from pipes, roofs, or even faulty seals around windows and doors can contribute to high humidity levels.

4. Monitor temperature and relative humidity: Aim for a comfortable indoor climate where the temperature is between 21°C and 25°C with an RH (Relative Humidity) level below 60%. Using a hygrometer can help you keep track of these conditions accurately.

5. Maintain cleanliness: Regularly clean surfaces that are prone to moisture accumulation, such as bathroom walls and kitchen counters. This helps prevent the establishment of mold colonies.

Remember, while these steps can significantly improve indoor air quality, professional intervention is often necessary for severe cases. Saniservice offers comprehensive services including mold remediation, decontamination, and environmental assessments which can provide lasting solutions to your concerns.
