Could humidifier cause my son's cold and mold?« Back to Previous Page

After the rain last month, I noticed a persistent damp smell in my son's room, especially during the night. It’s really concerning because he’s had a cold since it started, and I’m worried it might be due to mold or mildew growing from the humidifier we use regularly. Is there anything specific I should look out for or check in his room to ensure their health isn’t compromised?

Could humidifier cause my son's cold and mold?

Humidifiers can indeed contribute to the growth of molds and mildews under certain conditions. The persistent damp smell you're noticing could be a sign of such an issue, especially given your son has had a cold since it started. In Dubai/UAE, humidity levels are naturally higher due to the climate which makes it more favorable for mold growth.

Firstly, let's consider the role of humidifiers. They add moisture into the air, but if not maintained properly, they can become breeding grounds for microorganisms like molds and bacteria. The damp smell is often a good indicator that these are present in your son’s room. Molds release spores into the air which can cause allergic reactions or respiratory issues—such as colds or asthma attacks—in sensitive individuals.

Here's what you should check:

1. Cleanliness: Ensure the humidifier and its parts, including the water tank and the filter, are thoroughly cleaned and disinfected regularly. Use approved cleaning products recommended by the manufacturer.
2. Water quality: Use distilled or demineralized water instead of tap water to prevent mineral buildup that can promote mold growth.
3. Humidity levels: Keep an eye on your home’s humidity levels using a hygrometer. Ideal indoor relative humidity should be between 40-60%. Excessively high humidity promotes mold development.
4. Ventilation: Ensure proper ventilation in the room to reduce moisture buildup.

If you suspect that molds are present, it's best to have an inspection by professionals who can identify the species and extent of the problem. In Dubai/UAE, regulations require that buildings maintain safe indoor air quality standards, but self-inspections might not cover all aspects. A professional environmental inspector would be able to assess the situation accurately.

Call 800-MOLDS or email hello@saniservice.com for a consultation if you're unsure about what to do next. They can provide expert advice and treatment options to ensure your son's room is safe and healthy.

Remember, maintaining proper indoor air quality is crucial in our humid climate here in Dubai/UAE. By addressing potential mold issues early on, you can prevent further health complications for your family.
