Can an old dehumidifier cause health issues?« Back to Previous Page

After the rain last month, I noticed a musty smell lingering in my children's bedroom, and they’ve both started coughing more frequently. The dehumidifier I have is old and barely seems to make a dent in the humidity levels. Is there anything else I can do to reduce the moisture and ensure their health?

An old dehumidifier can indeed contribute to health issues especially in an environment like Dubai where humidity levels are higher due to the climate and periodic rainfall. The musty smell you've noticed along with increased coughing from your children could be indicative of excessive moisture leading to mold growth, which is a common issue during periods of high humidity.

In Dubai, as per local regulations (UAE Code of Practice for Building Services – HVAC Systems, 2016), maintaining appropriate indoor relative humidity levels between 30-60% is recommended. This can help reduce the risk of moisture-related issues such as mold and mildew, which are known to cause respiratory problems.

Your current dehumidifier might be struggling due to its age or inefficiency, making it hard to maintain these ideal conditions. It's not uncommon for older units to lose effectiveness over time, especially if not serviced regularly. Some signs that indicate your dehumidifier may need replacement include:

• The unit is not removing enough moisture despite being plugged in and running.
• There are visible mold spots or musty odors inside the machine.
• The filters of the unit appear to be clogged with dust, dirt, or other debris.

If you suspect that your current dehumidifier is inadequate, it would be prudent to consider replacing it. Opting for a newer model with higher efficiency could significantly improve indoor air quality and moisture control. For best results, choose a unit designed for the specific size of your space; for instance, if your children's bedroom measures 120 square meters, you'd want a dehumidifier rated for that area.

Additionally, regular maintenance is crucial. Even with an efficient unit, cleaning and servicing it every six months can keep it performing optimally. This includes replacing or washing the filters, ensuring proper airflow around the unit, and checking for any damages.

Given the importance of maintaining good indoor air quality in Dubai, I strongly recommend getting a professional inspection to assess the current state of your home's moisture control systems. Call 800-MOLDS or email hello@saniservice.com for an expert evaluation. Early intervention can prevent more serious health issues down the line.

In conclusion, addressing this issue promptly could alleviate the discomfort and potential health risks associated with high humidity in Dubai homes.
