How to deep clean home air and surfaces after sandstorm?« Back to Previous Page

Post-sandstorm dust in Dubai is extremely fine and can linger for weeks, penetrating deep into AC systems and settling on all surfaces. The most effective approach combines surface cleaning with air purification, as dusting alone often just redistributes the particles.

Start with your HVAC system, as it's the primary air circulator. Replace all AC filters with high-efficiency MERV 11 or higher filters, which are designed to capture fine particulate matter. If the coughing persists, have a professional inspect and clean the internal evaporator coils and ductwork; post-storm debris often clogs these components, forcing contaminated air back into your home.

For surfaces, use a microfiber cloth dampened with water—dry dusting will not capture the fine silt. Vacuum all upholstery and carpets with a HEPA-filter vacuum cleaner, as standard vacuums often exhaust the finest particles back into the air. Consider a professional deep clean for carpets and soft furnishings, as they act as a reservoir for this dust.

To purify the air, run certified HEPA air purifiers continuously in the main living areas and bedrooms, especially while sleeping. Maintain indoor humidity between 40-60% using a dehumidifier; this helps weigh down airborne dust and prevents mould growth, which can be triggered by the combination of dust and our high humidity.

If symptoms continue despite a thorough cleaning, a professional indoor air quality assessment can identify if finer particulate or biological contaminants are still present.
