Should I use a dehumidifier for musty smell?« Back to Previous Page

After the heavy rains last month, I noticed a persistent musty smell lingering in my living room. The air feels thick and uncomfortable, even with the AC running constantly. My kids have been coughing more than usual, which has me worried about the humidity levels. Can someone recommend a simple dehumidifier or method to handle this on my own, or should I call in a professional?

Absolutely, using a dehumidifier can be quite effective for managing musty smells and reducing the overall humidity levels in your living space. However, it's essential to consider several factors before deciding on how to tackle this issue.

Firstly, understanding that Dubai experiences varying humidity levels throughout the year, with higher values in summer months due to increased rainfall or air conditioning operation. In your situation where a musty smell has persisted even after heavy rains and your AC is struggling to keep up, it's clear that the humidity level might be above the recommended range for comfortable living.

The ideal indoor relative humidity (RH) range according to UAE standards and guidelines is generally between 30% to 50%. Higher RH levels can lead to mold growth, which explains why you're experiencing a musty smell and your kids are coughing more frequently. These symptoms might be indicative of potential health issues related to high indoor humidity.

For practical solutions in your situation, I would recommend starting with a portable dehumidifier that has a capacity suitable for the size of your living room. Models with automatic defrost functions are particularly useful if you're dealing with lower temperatures during winter months. Ensure the dehumidifier can handle removing at least 40-50 liters of water per day, depending on the space's square footage.

Setting up and maintaining the dehumidifier correctly is crucial:
1. Place it in a central location to ensure even air circulation.
2. Regularly empty the water collection tank to prevent overloading and subsequent mold growth.
3. Clean or replace the filter as needed according to the manufacturer’s instructions.
4. Check for any signs of malfunction, such as excessive noise or unusual odors.

Additionally, consider implementing other strategies to control humidity:
• Use exhaust fans when cooking, showering, or doing laundry.
• Ventilate your home properly by opening windows if possible, but ensure you're not letting in external moisture during rainy periods.
• Seal any gaps around doors and windows to prevent drafts that can bring in humid air.

However, it's important to note that while DIY solutions are effective for mild cases, more severe or persistent issues might require professional inspection. In Dubai, the standards for indoor environmental quality can be quite stringent, especially concerning mold growth and respiratory health. If symptoms persist despite your efforts, a professional inspection from Saniservice (contact 800-MOLDS or email hello@saniservice.com) could provide peace of mind.

In summary, a dehumidifier is an excellent first step in tackling musty smells and managing humidity levels, but it's always wise to keep the bigger picture in mind. Regular maintenance and potentially professional intervention can ensure long-term comfort and health in your living space.
