Should I worry about high humidity causing mustiness?« Back to Previous Page

After the heavy rains last month, I noticed a persistent musty smell in my children's room, especially after they take their naps. The dehumidifier we have is quite old and doesn't seem to be doing much to reduce the humidity levels. Are there any signs I should look out for that might indicate higher than normal humidity levels?

Absolutely, high humidity can definitely cause mustiness and is a common issue to tackle, especially in the warm and humid climate of Dubai. The persistence of that musty smell, especially after your children take their naps, suggests elevated moisture levels in their room, which could be due to various factors such as inadequate ventilation or an improperly functioning dehumidifier.

In the UAE, particularly in Dubai, humidity can often exceed recommended levels, especially during summer months. The Environmental Protection Agency (EPA) guidelines suggest maintaining indoor relative humidity between 30% and 50%. However, for optimal comfort and to prevent mold growth, it's advisable to keep it closer to the lower end of this range.

You should be vigilant about signs indicating high humidity levels in your home. These might include:
• Condensation on windows or walls
• Musty odors, as you've experienced
• Mold or mildew spots, which can often appear on damp areas like corners and behind furniture
• Peeling paint or wallpaper
• Structural damage from water

Given the age of your dehumidifier and its apparent ineffectiveness, it would be wise to consider a more efficient unit. Dehumidifiers come in different capacities based on their ability to remove moisture per day; for instance, a 50 pint model might be suitable for small rooms like children’s bedrooms.

Regular maintenance is crucial too. Check the dehumidifier's performance by measuring the humidity levels both before and after it has run for an extended period. If you notice little change in the readings, it may be time to replace or service your unit.

Considering your specific situation, I would recommend calling 800-MOLDS or emailing hello@saniservice.com for a professional inspection and remediation if necessary. They can assess the humidity levels throughout your home, identify any underlying issues, and provide solutions tailored to your needs.

Remember, addressing high humidity promptly not only improves air quality but also protects your property from damage caused by moisture.
