How Poor Indoor Air Quality Can Affect Health and Everyday Life

A modern apartment in Dubai may offer spectacular skyline views, sophisticated air conditioning and beautifully designed interiors. An office in Riyadh might feature advanced technology, energy-efficient lighting and comfortable working spaces. Yet one important part of these environments often receives less attention than the furniture, architecture or temperature: the quality of the air people breathe indoors.

Across the Gulf, residents spend substantial amounts of time inside homes, offices, shopping malls, schools and other enclosed buildings. During periods of intense heat, outdoor activities become less practical, making indoor environments particularly important to everyday comfort and health.

This is why Indoor Air Quality in Gulf Cities deserves greater attention as an issue involving public health, building design, energy efficiency and urban development.

Indoor air can contain pollutants from several sources. Outdoor dust may enter through ventilation systems or building openings, while cleaning products, cooking activities, furniture, building materials and excess moisture can introduce additional contaminants.

Air conditioning helps maintain comfortable indoor temperatures, but cooling a room does not automatically mean that the air is clean or adequately ventilated.

A building may feel cool while still experiencing problems involving insufficient fresh air, accumulated particles or poorly controlled humidity.

Research published in June 2025 in the journal Indoor Environments highlighted this challenge in the UAE. The study, developed following work commissioned by the Abu Dhabi Public Health Centre, identified important gaps in understanding indoor pollution across the country and emphasised the distinctive difficulties created by extreme temperatures, desert dust and energy-efficient building design.

The issue is also receiving regulatory attention. Dubai’s Public Health Law No. 5 of 2025 includes provisions addressing indoor air quality, ventilation, building maintenance and the responsibilities of property owners.

These developments suggest that indoor environmental quality is becoming an increasingly important consideration for Gulf residents, property developers and building operators.

However, addressing the problem requires more than purchasing an air purifier or changing an air-conditioning setting.

The most effective solutions involve understanding pollution sources, maintaining suitable ventilation, controlling moisture and selecting appropriate filtration systems.

As Gulf cities continue expanding, the quality of indoor air could become an important measure of how successfully buildings support the people who live and work inside them.

Indoor Air Quality in Gulf Cities: Why It Matters More Than People Realise

Indoor air quality refers to the condition of air within buildings and the potential presence of pollutants that can affect human health, comfort and wellbeing.

Unlike outdoor air pollution, which is often discussed through weather reports and environmental monitoring, indoor pollution may be less visible. Residents can spend considerable time inside a building without recognising the sources affecting its air.

The US Environmental Protection Agency explains that people typically spend about 90% of their time indoors. This is a general estimate, not a measured percentage for every Gulf resident, but it illustrates why indoor exposure deserves attention.

Why the Gulf Climate Creates Particular Challenges

Cities such as Dubai, Abu Dhabi, Doha and Riyadh experience long periods of high temperatures. Many buildings rely heavily on mechanical cooling to maintain comfortable indoor environments.

During the hottest months, residents may keep windows closed and depend on air-conditioning systems for much of the day. This makes the design and maintenance of ventilation systems especially important.

Buildings must also manage the balance between introducing outdoor air and limiting the entry of dust and other pollutants.

Indoor Air vs Outdoor Air

Outdoor air pollution can originate from transportation, industry, construction and natural dust events. Indoor air contains some of these contaminants when they enter buildings, but it can also develop additional pollution from activities within the property.

Why a Comfortable Room May Still Have Air Quality Problems

Temperature and air quality are related but different aspects of indoor comfort. A cooling system may reduce room temperature without removing every pollutant or introducing sufficient fresh air.

Similarly, a room with a pleasant fragrance may still contain airborne particles or chemical pollutants. Smell alone is not a reliable indicator of air safety, because some harmful gases are odourless.

For residents, the first step is recognising that comfortable air conditioning does not necessarily guarantee healthy indoor air.

7 Hidden Sources of Indoor Air Pollution in Gulf Homes and Buildings

Indoor pollution can develop through everyday activities, building conditions and the movement of outdoor contaminants into enclosed spaces.

Understanding these sources helps residents and property managers identify which interventions may be useful.

1. Desert Dust and Outdoor Particles

Dust is an important environmental consideration across many Gulf locations. Windblown particles can enter buildings through poorly sealed openings, ventilation systems and repeated door movements.

Fine particles may remain suspended in indoor air, while larger particles settle on furniture, floors and other surfaces.

The amount entering a particular building depends on weather, filtration, building design and maintenance conditions.

2. Cooking and Kitchen Emissions

Cooking can generate airborne particles and, depending on the appliance and fuel, combustion-related pollutants.

Frying, grilling and high-temperature cooking may produce substantial indoor emissions, particularly when kitchen ventilation is inadequate.

Suitable extraction systems can help reduce exposure, although their performance depends on installation, maintenance and correct use.

3. Cleaning Products and Fragrances

Some cleaning products, air fresheners and scented materials release volatile organic compounds, commonly known as VOCs.

These chemicals vary widely, and their potential effects depend on the substance and exposure.

Products should be used according to their instructions, with appropriate ventilation and without mixing incompatible chemicals.

4. Building Materials and Furniture

Paints, adhesives, furnishings and certain manufactured wood products can release chemical emissions.

Formaldehyde is one example of a substance that can be associated with some building materials.

Choosing appropriate low-emission products and following installation guidance can help reduce potential exposure.

5. Excess Moisture and Mould

Leaks, condensation and poorly controlled humidity can create conditions that support mould growth.

A musty smell, visible discolouration or recurring damp patches may indicate a moisture problem requiring investigation.

Cleaning without correcting the underlying water source may allow the problem to return.

6. Tobacco Smoke and Combustion Sources

Indoor smoking introduces harmful pollutants into shared air.

Fuel-burning appliances may also release gases such as carbon monoxide when improperly installed or operated.

Because carbon monoxide cannot be reliably detected by smell, suitable safety procedures and alarms are important where combustion risks exist.

7. Poorly Maintained Ventilation Systems

Air-conditioning and ventilation equipment require appropriate inspection and maintenance.

Blocked filters, damaged components or unsuitable airflow can affect indoor environmental performance.

However, a dirty-looking air vent alone does not establish that an entire building is dangerously polluted. Proper assessment should consider the actual condition and operation of the system.

Common Pollution Sources Compared

The most useful response depends on the actual pollution source. A single product or technology cannot address every type of indoor air problem.

How Poor Indoor Air Quality Can Affect Health and Everyday Life

The health effects of indoor pollution depend on the substances involved, their concentrations, exposure duration and individual vulnerability.

Some pollutants can irritate the eyes, nose and throat, while others are associated with respiratory or cardiovascular risks following sufficient exposure.

The World Health Organization identifies air pollution as an important public health concern, although its global household pollution estimates largely reflect exposure from polluting cooking fuels in particular populations. Those figures should not be used to estimate the health burden from air-conditioned apartments in Dubai or other Gulf cities.

Respiratory Health and Allergies

People with asthma, allergies or other respiratory conditions may be more sensitive to certain airborne particles and biological contaminants.

Dust, smoke and mould-related exposure can aggravate symptoms in susceptible individuals.

However, coughing or nasal irritation does not automatically establish that a building has poor air quality. Similar symptoms can have other causes, making appropriate medical assessment important when problems persist.

Children and Older Residents

Some groups may be more vulnerable to air pollution because of age, health conditions or other circumstances.

Children’s developing respiratory systems and the needs of older adults can make exposure prevention especially relevant.

Schools, nurseries and residential buildings serving these populations should therefore prioritise suitable ventilation, moisture management and maintenance.

Offices and Everyday Comfort

Poorly ventilated workspaces can become uncomfortable, particularly when many people occupy a limited area.

Elevated carbon dioxide readings can sometimes suggest that ventilation is insufficient for the occupancy level, but carbon dioxide is not a complete measure of indoor air safety.

Research on indoor environmental quality also examines connections with perceived comfort and cognitive performance. These relationships are influenced by several factors, including temperature, noise, lighting and ventilation.

Why Health Claims Need Careful Interpretation

A building with poor indoor air conditions may create real problems, but it would be misleading to attribute every headache, tiredness or concentration difficulty to air pollution.

Similarly, installing a filtration device does not guarantee that residents will experience measurable medical improvements.

Health Considerations at a Glance

For residents, the goal should be to identify genuine environmental problems and address them through evidence-based measures rather than purchasing products based on alarming marketing claims.

Air Conditioning, Ventilation and Humidity: The Gulf Building Challenge

Air conditioning is essential to indoor comfort across much of the GCC, but its role in air quality is frequently misunderstood.

A typical cooling system removes heat from indoor air. Depending on its design, it may also help remove moisture and filter some particles.

However, cooling, ventilation and filtration are separate functions that need to work together.

Why Cooling Does Not Automatically Mean Fresh Air

Some room air-conditioning units primarily recirculate indoor air.

Without a suitable fresh-air system or controlled outdoor-air supply, pollutants produced inside a room may accumulate.

Larger buildings often use more complex heating, ventilation and air-conditioning systems that can incorporate outside air, filtration and humidity control.

The actual performance depends on design, operation and maintenance.

The Challenge of Outdoor Dust

Opening windows can increase ventilation under suitable conditions, but it can also introduce outdoor pollution.

During dusty weather, simply opening windows may worsen particle exposure.

In mechanically ventilated buildings, appropriately filtered outdoor air can provide an alternative, although the system must be designed and operated correctly.

Why Humidity Control Matters

Excess moisture creates conditions that can support mould and other biological problems.

The US EPA generally recommends maintaining indoor relative humidity between 30% and 50% where feasible.

This is a general moisture-management recommendation rather than a universal guarantee of comfort for every building or occupant.

Different Building Systems Compared

Energy Efficiency vs Indoor Air Quality

Gulf buildings need to manage high cooling demand while providing suitable indoor environmental conditions.

Increasing outdoor-air ventilation can create additional cooling and dehumidification requirements.

Reducing ventilation excessively to save energy, however, may compromise air quality.

Building designers must balance energy performance, occupant needs and applicable technical standards rather than treating either objective as optional.

UAE and Saudi Arabia Indoor Air Quality Regulations and Research

Indoor environmental quality is receiving increasing attention in government policy, building standards and scientific research.

However, rules differ between jurisdictions, and a technical guideline should not automatically be treated as a universal legal requirement for every existing property.

Dubai’s Public Health Law

Dubai’s Law No. 5 of 2025 concerning public health includes specific provisions addressing the health of built environments.

The law identifies responsibilities involving ventilation, indoor air quality, building materials, inspection and maintenance.

It also requires property owners to comply with applicable environmental and health standards issued by the relevant authority.

These requirements establish an important legal foundation, but their precise application depends on the property and implementing standards.

Dubai’s Green Building Framework

Dubai’s green building requirements include provisions related to indoor environmental quality.

For new buildings within the relevant scope, the framework addresses pollutants such as formaldehyde, total volatile organic compounds and suspended particulates.

The requirements also include testing and compliance procedures.

A regulatory concentration limit should not be confused with a World Health Organization health-based guideline. Different standards may use different measurement periods and serve different purposes.

The UAE National Air Quality Agenda 2031

The UAE’s National Air Quality Agenda 2031 recognises indoor pollution as an environmental health concern.

The agenda identifies the role of building materials, ventilation and local building-performance programmes.

It also notes that indoor air quality management has historically involved different approaches across individual emirates.

Research in Abu Dhabi

The 2025 study commissioned through the Abu Dhabi Public Health Centre identified major gaps in indoor air quality research.

Researchers highlighted desert dust, building ventilation and the limited availability of representative indoor measurements as areas requiring attention.

This is an important distinction: the available evidence supports concern and further investigation, but it does not establish that every building in the UAE has poor air quality.

Saudi Arabia’s Building Standards

Saudi Arabia’s Building Code includes provisions addressing ventilation and indoor air quality.

The Saudi Code for Energy Conservation for nonresidential buildings, SBC 601, identifies HVAC systems and ventilation requirements among its principal areas.

Requirements differ according to building type and the applicable code edition.

Regulatory Approaches Compared

For property owners and developers, compliance should be based on the requirements applicable to the specific building, rather than general online advice.

7 Practical Ways to Improve Indoor Air Quality in Gulf Homes and Offices

Improving indoor air quality does not always require expensive technology or major renovations.

The most effective measures generally begin with identifying pollution sources, managing moisture and ensuring that building systems function as intended.

The US EPA recommends a combination of source control, suitable ventilation and filtration rather than relying exclusively on air-cleaning equipment.

1. Maintain Air-Conditioning and Ventilation Systems

Regular maintenance can help cooling and ventilation systems operate as designed.

Filters should be inspected and replaced according to manufacturer guidance, while unusual moisture, airflow problems or mechanical faults should be assessed by qualified technicians.

Residents in managed buildings may need to coordinate maintenance requests with their property managers.

2. Control Dust at Entry Points

Outdoor dust can enter through doors, windows and ventilation openings.

Suitable entrance mats, appropriate cleaning methods and attention to building seals may help reduce particle accumulation.

During dust events, residents should consider outdoor conditions before opening windows.

3. Use Effective Kitchen Ventilation

Cooking can generate particles and gases that affect indoor air.

A correctly installed and maintained range hood that exhausts outdoors is often preferable for removing cooking emissions.

Recirculating hoods may help with selected contaminants but do not provide the same function as an effective externally exhausted system.

4. Address Moisture Problems Quickly

Leaks, condensation and damp materials should be investigated before mould becomes established.

The underlying moisture source must be corrected, not merely covered with paint or fragrance.

Extensive contamination or recurring water damage may require professional assessment.

5. Choose Appropriate Air Filtration

Portable air cleaners can reduce certain airborne particles when correctly selected and operated.

The EPA recommends considering clean air delivery rate, or CADR, relative to room size.

HEPA filtration can be effective for particles, while certain gas-related pollutants require different approaches.

Devices marketed as ozone generators should not be used in occupied spaces.

6. Reduce Unnecessary Indoor Chemical Emissions

Using strongly scented products or multiple cleaning chemicals does not necessarily make a room healthier.

Choosing suitable low-emission materials, following product instructions and avoiding unnecessary indoor pollution sources can help.

Residents should never mix cleaning products unless the manufacturer explicitly indicates that doing so is safe.

7. Monitor Problems Rather Than Relying on Guesswork

An indoor air monitor may help identify certain patterns, but consumer devices differ in accuracy and in the pollutants they measure.

Persistent dampness, unusual odours or suspected combustion problems may require professional investigation.

Monitoring should support practical decisions rather than create unnecessary concern over individual readings.

Practical Improvement Checklist

What About Indoor Plants?

Houseplants can add visual appeal and improve the atmosphere of an indoor space.

However, ordinary numbers of indoor plants should not be relied upon to remove enough pollutants to replace ventilation and filtration.

Improperly maintained plant soil may also introduce additional moisture concerns.

The most dependable approach remains a combination of pollution prevention, appropriate building systems and regular maintenance.

The Business of Healthy Buildings: Costs, Technology and Real Estate Value

Indoor air quality is also becoming relevant to commercial property management, hospitality, education and building technology.

For businesses, indoor environmental quality involves both regulatory responsibilities and operational decisions.

A building owner may invest in filtration upgrades, monitoring or maintenance to address identified problems and improve the performance of the property.

However, such investments should be evaluated through measured outcomes rather than assumed financial gains.

The Role of Healthy Building Design

Developers can incorporate suitable ventilation, low-emission materials and moisture-resistant construction practices during the design process.

Addressing these factors before a building becomes occupied may be more practical than making extensive modifications later.

Building-performance standards and technical assessments can support decision-making, but certifications should not replace proper operational maintenance.

Opportunities for Building Technology Companies

Indoor air quality creates commercial demand for specialist equipment and services.

These may include air-quality monitoring, ventilation assessment, filter maintenance, building automation and professional environmental testing.

However, providers need appropriate technical qualifications and should avoid presenting consumer monitoring devices as equivalent to accredited laboratory measurements.

Illustrative Air Quality Improvement Budget

Consider a hypothetical medium-sized office allocating AED 50,000 to assess and improve indoor environmental performance.

These are hypothetical planning figures, not verified UAE contractor quotations. Actual spending depends on building size, existing systems and the problems identified.

Could Better Indoor Air Become a Real Estate Advantage?

Tenants and buyers may increasingly ask about ventilation, maintenance and environmental comfort when evaluating properties.

For landlords, demonstrating appropriate building performance can support transparency and confidence.

However, claims that improved indoor air automatically increases rents or property values require market-specific evidence.

Why Commercial Buildings Need Long-Term Planning

Hotels, schools, offices and shopping malls have different occupancy patterns and ventilation requirements.

An effective strategy should account for how each space is actually used rather than applying identical equipment settings everywhere.

Building owners should also consider ongoing electricity consumption, filter replacement and maintenance costs.

An investment in indoor air quality is therefore a continuing operational responsibility, not simply a one-time equipment purchase.

The Future of Indoor Air Quality in Gulf Cities and Frequently Asked Questions

As Gulf cities continue expanding, indoor environmental quality is likely to become a more visible part of conversations about healthy buildings and sustainable urban development.

The challenge is balancing energy-efficient construction with appropriate ventilation, filtration and moisture management.

Dubai’s public health requirements and ongoing research in Abu Dhabi demonstrate growing attention to these questions.

Smarter Building Monitoring

Modern building-management systems can collect information about temperature, humidity, ventilation and selected air-quality indicators.

These systems may help operators detect unusual patterns and evaluate equipment performance.

However, sensors require calibration, proper placement and interpretation.

An attractive dashboard cannot compensate for poorly maintained ventilation equipment or unresolved pollution sources.

Climate-Appropriate Building Design

The Gulf’s climate creates requirements that may differ from those in cooler regions.

Designers need to manage summer temperatures, outdoor dust and indoor moisture while limiting excessive energy use.

Research specific to regional conditions can help improve future building standards and operational practices.

Greater Awareness Among Residents

Public understanding of indoor air quality can support more informed choices about cleaning products, home maintenance and ventilation.

However, awareness campaigns should avoid exaggerated claims or suggesting that every indoor environment is unsafe.

Accurate information and practical guidance are more useful than creating unnecessary anxiety.
