How Construction Pollutes Indoor Air

When building or renovating a home or office in Kenya, the last thing many people consider is indoor air quality. However, how construction pollutes indoor air is an issue that directly affects your health, comfort, and productivity. Whether you are working on a site in Nairobi, Mombasa, or Eldoret, airborne pollutants from construction can settle indoors and linger for weeks or even months.

Understanding this problem can help you make informed decisions about air quality. Let’s explore how construction affects indoor air and how you can protect your space using air scrubbers and purifiers.

Why Indoor Air Quality Matters

Most people spend nearly 90 percent of their time indoors. Poor indoor air can cause:

• Headaches and fatigue
• Eye, nose, and throat irritation
• Respiratory problems like asthma
• Long-term health issues like lung disease

Children, pregnant women, and the elderly are especially vulnerable. In construction zones, the air becomes even more dangerous due to the high volume of dust, chemicals, and particles released during the work.

Common Indoor Air Pollutants from Construction

Let’s take a look at the major contributors to air pollution during building or renovation.

1. Dust and Particulate Matter

Construction activities generate large amounts of dust. These tiny particles float in the air and can remain suspended for long periods. When inhaled, they irritate the lungs and can trigger asthma or bronchitis.

2. Volatile Organic Compounds (VOCs)

Paints, varnishes, adhesives, and sealants used in construction often contain VOCs. These harmful chemicals evaporate into the air and can cause dizziness, headaches, and even damage to the liver and kidneys after prolonged exposure.

3. Silica and Cement Dust

Cutting or grinding materials like tiles, bricks, and concrete releases silica dust. This fine dust is known to cause serious lung diseases such as silicosis and cancer if inhaled repeatedly.

4. Mold and Moisture

In poorly ventilated construction sites, water can accumulate, especially during the rainy seasons. This encourages mold growth. Mold spores pollute the air and can trigger allergic reactions and respiratory issues.

5. Asbestos and Lead

While banned in many places, some older buildings in Kenya still contain materials with asbestos or lead. Renovation can disturb these materials, releasing toxic particles into the air.

How Construction Pollutes Indoor Air in Kenyan Homes and Offices

In Kenya, many construction projects are carried out with limited safety precautions. Workers and residents are rarely provided with proper respiratory protection, and windows are often left open, allowing outdoor contaminants to move indoors.

Moreover, most construction materials used locally are not low-emission certified. This means they are more likely to release dangerous gases and particles into your living space. Without effective ventilation or purification, these pollutants accumulate indoors, making your home or office a health hazard.

In urban areas like Nairobi or Kisumu, where construction is constant and homes are close to each other, even nearby building projects can impact your indoor air. The wind can easily carry dust and chemicals into your home, especially if windows and doors are left open for cooling.

What You Can Do to Stay Safe

Now that we understand how construction pollutes indoor air, what steps can you take to protect yourself and your loved ones?

1. Use Air Scrubbers and Air Purifiers

Air scrubbers are powerful machines that filter out dust, chemicals, and even odors from the air. Unlike regular fans or air conditioners, they clean the air rather than just moving it around.

Renting an air scrubber during your construction or renovation project is an affordable and smart solution. You can place it in rooms where work is being done or in adjacent areas to prevent the spread of pollutants.

Air purifiers with HEPA filters are another excellent option. They are especially useful in bedrooms and living spaces, where clean air is essential for restful sleep and overall wellbeing.

2. Improve Ventilation

Keep windows closed during active construction to avoid letting in dust. Once work is done, ventilate the space by opening windows on opposite walls for cross-breeze airflow. Use exhaust fans if available.

3. Choose Low-VOC Materials

Whenever possible, ask your contractor to use paints, glues, and finishes that are labeled low-VOC or VOC-free. These materials release fewer toxins and are much safer for indoor environments.

4. Clean Regularly

Wipe down surfaces with damp cloths to trap dust instead of just sweeping, which can stir particles into the air. Use vacuum cleaners with HEPA filters to effectively remove dust from carpets and upholstery.

5. Monitor Indoor Air Quality

You can now find affordable air quality monitors in the Kenyan market. These devices measure levels of dust, humidity, and harmful gases. By monitoring your indoor environment, you can act quickly when pollution levels rise.
