How can I reduce bedroom humidity?« Back to Previous Page

After the rain last month, I noticed a persistent musty smell lingering in the corner of my bedroom, especially during the evenings. The humidity seems to be particularly high there due to the large window overlooking the garden. My kids have been complaining of coughs and runny noses since we started spending more time indoors. Is there anything specific I can do to reduce the humidity in that part of the house or prevent it from happening again?

Reducing bedroom humidity is crucial to prevent mold growth and improve indoor air quality. In Dubai/UAE, maintaining optimal relative humidity levels can be a challenge due to the region's climate. The UAE's Building Code (2015) recommends that the indoor relative humidity should not exceed 60% in non-air-conditioned areas and 70% in air-conditioned spaces.

Firstly, it is essential to identify the source of high humidity in your bedroom. In this case, the large window overlooking the garden could be a contributing factor. Condensation forms on cold surfaces like windows when warm, humid air comes into contact with them. To address this issue, consider installing storm windows or heavy curtains which can help insulate and reduce heat loss.

Another effective method to lower humidity is by using dehumidifiers. Opt for a unit that suits your bedroom size; typically, a 15-20 liter per day capacity model will suffice. Ensure it has a cleanable filter and a water tank that can hold at least 3 liters of collected moisture. Place the dehumidifier near the window to target the high-humidity area most effectively.

Ventilation is another key factor in managing humidity levels. Open windows for short periods during cooler times, but be cautious of external conditions like heavy rain or strong winds. In your case, opening a window may not be ideal due to the persistent musty smell. Instead, consider installing an exhaust fan that can pull moisture-laden air out of the room and expel it outside. This is particularly effective in bathrooms but can also be used in bedrooms.

Utilizing air conditioning systems can significantly reduce indoor humidity. Set your AC at 70-75°F (21-24°C) to ensure efficient dehumidification, as lower temperatures will condense more water vapor from the air. Regular maintenance of your HVAC system is critical; schedule annual servicing by a certified technician.

Finally, it’s wise to conduct an environmental inspection if you notice persistent issues or health concerns. Saniservice can help with this - contact 800-MOLDS or email hello@saniservice.com for professional guidance and remediation services. Remember, addressing high humidity not only improves your indoor environment but also contributes to better health outcomes for your family.

By implementing these strategies, you should see a noticeable reduction in bedroom humidity and an improvement in air quality, leading to fewer respiratory issues like coughs and runny noses among your children.
