Should high humidity cause concern in my closet?« Back to Previous Page

After the heavy rain last month, I noticed a musty smell lingering in my bedroom closet. The humidity gauge on my phone reads over 70% even after running the dehumidifier all day. Can anyone recommend any DIY solutions or suggest when it might be time to call a professional?

Absolutely, high humidity should indeed cause concern in your closet. In the UAE context, particularly Dubai, maintaining an indoor relative humidity (RH) level below 60% is crucial to prevent the growth of mold and mildew which could lead to structural damage and health issues.

Firstly, let's address why a RH over 70% in a closet is problematic. High humidity creates an ideal environment for microorganisms such as fungi, bacteria, and dust mites. In the UAE, with its warm and humid climate, these conditions can quickly deteriorate the quality of stored items like clothing, shoes, and other textiles. Moreover, high humidity promotes corrosion of metals and rusting of iron-based objects.

Given your experience with a musty smell and the persistent high RH reading even after running a dehumidifier, it’s important to investigate thoroughly. Here are some steps you can take:

1. Professional Inspection: Contact local environmental inspection companies such as those offering 800-MOLDS or email hello@saniservice.com for an expert assessment. They will use specialized equipment like thermal imaging cameras and moisture meters to pinpoint the sources of excess moisture.

2. Ventilation Assessment: Check if your closet has adequate ventilation. In Dubai, ensuring proper airflow is essential. Consider installing a fan or opening windows (if weather permits) to reduce humidity levels naturally.

3. Dehumidifier Placement: Positioning the dehumidifier correctly can be critical. Place it near the source of moisture for maximum effectiveness. Ensure it's not placed on a carpeted surface which could interfere with its operation and efficiency.

4. Closet Design Modifications: If your closet is in an area prone to high humidity, consider adding mold inhibitors or implementing a dehumidification system integrated into the building’s HVAC (Heating, Ventilation, and Air Conditioning) design.

5. Regular Maintenance Checks: Regularly clean and maintain your dehumidifier as per manufacturer guidelines. Also, inspect areas like wall junctions, pipes, and air conditioning systems for leaks or condensation that might be contributing to the high humidity levels.

In Dubai’s climate, where temperatures can soar during summer months, maintaining indoor air quality is paramount. High humidity can lead to not only structural damage but also affect the health of occupants through increased allergens and respiratory issues. Therefore, addressing this issue with diligence and professional help will ensure a healthier and more comfortable living environment in your home.

Remember, prevention is key! Regular monitoring and maintenance are crucial steps towards maintaining optimal indoor air quality in Dubai's challenging climate conditions.
