Is sealing windows causing indoor allergens?« Back to Previous Page

After the heavy dust storms this spring, we’ve noticed a persistent musty smell in our bedroom, especially at night. It's making my husband’s asthma worse, and the kids have been complaining of itchy eyes and a stuffy nose. The windows are sealed tightly, so I'm worried about mold or some other allergen building up. Is there anything specific we should be doing to clean better and improve our air quality?

Sealing windows can indeed be a double-edged sword for indoor air quality. While it helps maintain the temperature and keeps dust out, it also restricts airflow, making your home more susceptible to mold growth if moisture levels are not managed properly. In Dubai/UAE, especially with the climate changes from hot days to cooler nights, moisture can accumulate easily inside sealed rooms, leading to dampness and subsequent mold issues.

The musty smell you're experiencing could be a sign of mold development. Mold thrives in humid environments and can produce allergens that worsen asthma symptoms and irritate eyes and noses. It's crucial to address this issue promptly to prevent further health problems for your family.

Firstly, ensure the bedroom has adequate ventilation even when windows are sealed. You might consider using exhaust fans or dehumidifiers to keep moisture levels down. Checking for any water leaks in walls or around pipes is also vital; these can be breeding grounds for mold.

Secondly, regular cleaning and maintenance of your home are key. Vacuuming carpets and dusting surfaces regularly can help reduce allergens. For hard-to-reach areas like behind furniture or inside closets, consider using a microfiber cloth that attracts more dust than traditional cloths.

Thirdly, inspecting for signs of mold is important. If you notice dark spots or fuzzy patches on walls or ceilings, it’s time to call in the experts. In Dubai/UAE, companies like MOLDS can perform professional inspections and remediation if necessary. Their services are available at 800-MOLDS (800-66537) or via email at hello@saniservice.com.

Lastly, maintaining a clean environment isn’t just about physical cleaning; it’s also important to keep your home free from pests like mice and cockroaches. These can also introduce allergens that trigger respiratory issues.

By following these steps, you should be able to improve the indoor air quality in your home significantly. Remember, early detection is key to preventing serious health complications.
