Should I install a dehumidifier for my master bedroom?« Back to Previous Page

After the heavy rain last month, I noticed a musty smell in the master bedroom closet, especially after it rained. The clothes stored there seem to be getting damp even though they’re in sealed bags. Should I consider installing a dehumidifier? What size would you recommend for an average-sized bedroom?

Absolutely, installing a dehumidifier is a wise decision for your master bedroom situation. The presence of musty odours and dampness even within sealed bags can be indicative of elevated humidity levels. In the UAE, particularly during the monsoon season or heavy rains, such issues are not uncommon.

In Dubai, the climate can lead to high relative humidity levels indoors, especially in areas with poor ventilation. The primary concern with high humidity is the potential for mold growth and structural damage to your home's materials over time. It’s advisable to have a professional conduct an inspection before proceeding, as they can provide accurate measurements of your bedroom's current moisture content.

For a typical-sized master bedroom, I would recommend considering a dehumidifier with a capacity between 50 to 70 pints per day (ppd). This size is suitable for rooms ranging from approximately 180 to 240 square feet. It’s essential to select a model that has a dedicated room setting, as this mode adjusts the unit's performance based on the interior conditions.

When choosing a dehumidifier, look for models with adjustable settings and an auto-drain function if possible. This will help maintain optimal humidity levels without constant monitoring. Additionally, ensure that it’s Energy Star certified to optimize energy efficiency.

Given the specifics of your situation, it might be beneficial to have regular maintenance checks by a professional. This can include cleaning the unit regularly and checking its performance against the desired humidity level (usually 50% or lower in most cases).

Remember, if you notice persistent issues despite having a dehumidifier installed, there may be underlying moisture sources that need addressing such as leaks from plumbing or roof damage.

In summary, investing in a properly sized dehumidifier is crucial for maintaining indoor air quality and preventing moisture-related issues. For more detailed advice tailored to your specific circumstances, feel free to contact us at 800-MOLDS (800-66537) or email hello@saniservice.com.
