The highest-impact steps for better indoor air quality are keeping the AC system's filters, coils and ducts clean, controlling indoor humidity, ventilating periodically, and reducing indoor sources of pollutants like certain cleaning products and air fresheners.
Start With the AC System
Since the AC recirculates the largest volume of air in most homes, a dirty filter, coil or duct system has more effect on indoor air quality than almost anything else that's typically blamed, like fabric or furniture. Addressing the AC side first tends to produce the most noticeable improvement.
Control Humidity, Not Just Temperature
Indoor humidity above roughly 60% creates favourable conditions for mould and dust mites, both of which are common triggers for allergy and respiratory symptoms. A well-maintained, correctly sized AC system is usually the most practical way to keep humidity in a healthier range.
Be Aware of Indoor Pollution Sources
Certain cleaning sprays, air fresheners, and some furniture or paint products release volatile compounds into indoor air, and in a sealed, air-conditioned home those compounds have fewer ways to disperse than in naturally ventilated spaces. Occasional ventilation, and choosing lower-emission products where practical, both help offset this.

Frequently Asked Questions
Do air purifiers meaningfully improve indoor air quality?
They can help with airborne particles, but they don't address dust or biological growth already inside AC ductwork, which needs to be dealt with separately.
Is opening windows a good idea in Abu Dhabi?
Brief ventilation is fine and can help with pollutant buildup, but during dust events or peak heat it's usually better to rely on filtration rather than open windows for extended periods.
What's the single most impactful step for better air quality?
For most homes, getting the AC's ducts and coils properly cleaned addresses more of the problem than any single product or gadget.
