How to lower humidity in a bedroom for asthma?« Back to Previous Page

Good question, and a very common issue here in Dubai. The fact that your AC is running constantly but not effectively controlling humidity is a major red flag that points directly to the AC unit itself. A dehumidifier is a temporary fix, but you'll be fighting a losing battle and a huge electricity bill if the core AC issue isn't resolved.

First, the AC is your primary dehumidifier. It removes moisture from the air as it cools. The problem you're describing—cold but damp air—often indicates the unit is cooling but not running long enough in its dehumidification cycle. This can be caused by an oversized unit, a clogged drain line, a dirty evaporator coil, or a failing compressor. The constant running suggests it's struggling to reach the set temperature due to one of these issues.

Before investing in a standalone dehumidifier, you MUST have your HVAC system inspected. A unit not properly dehumidifying can lead to mold growth inside the ductwork, which is a severe asthma trigger. Regulations here, like Dubai's DM guidelines, emphasize proper AC maintenance for tenant health and safety.

My professional recommendation:
1. Get a professional AC technician to check the refrigerant charge, clean the coils, and ensure the condensate drain is clear. This is step one.
2. Ensure the unit is correctly sized for the room; oversized units are a common cause of high humidity.
3. If the AC is confirmed to be operating correctly, then consider a high-capacity desiccant dehumidifier for the bedrooms, as standard compressor dehumidifiers are less effective in our high-heat climate.

Given the asthma concern, this isn't just about comfort but health. Damp pajamas indicate a humidity level well above the recommended 45-55%, creating a perfect environment for dust mites and mold.
