Stay indoors, reduce outdoor air infiltration to indoors, and use air filters
Staying indoors is a good way to avoid exposure to outdoor air pollution. However, indoor air quality can also be poor, so it is important to take steps to reduce outdoor air infiltration and use air filters to improve the air quality in your home.
Reducing outdoor air infiltration involves limiting the amount of outdoor air that enters your home. This can be done through proper ventilation and sealing openings, joints, and cracks in walls, floors, and ceilings, as well as around windows and doors. Natural ventilation, such as opening windows and doors, can help improve indoor air quality by reducing indoor pollutants, but it can also allow outdoor pollutants to enter your home. Mechanical ventilation systems, such as outdoor air intakes associated with HVAC systems, can be more effective at reducing outdoor air infiltration. Advanced designs for new homes are starting to include these mechanical features to bring filtered outdoor air inside.
Upgrading the air filter in your furnace or central heating, ventilation, and air conditioning (HVAC) system can help improve indoor air quality. Portable air cleaners, also known as air purifiers or sanitizers, are designed to filter the air in a single room or area and can be an effective supplement to source control and ventilation. Table-top air cleaners may not remove pollutants from strong nearby sources, so it is important to select an appropriate air cleaner for your needs.
In addition to using air filters, it is important to reduce indoor sources of pollution. Some sources, like those containing asbestos, can be sealed or enclosed, while emissions from others, like gas stoves, can be adjusted. Choosing efficient appliances and heating systems, and turning off electrical items when not in use, can also help reduce indoor air pollution.

Use public transport, walk, or cycle instead of driving
Using public transportation, such as buses, trains, subways, and ferries, is a more environmentally friendly alternative to driving. Public transportation reduces greenhouse gas emissions, with transit riders consuming half as much gasoline per person compared to those relying on private vehicles. It also reduces traffic congestion, making it a safer and often faster mode of transportation.
Walking and cycling are excellent alternatives to driving, especially for shorter trips. These modes of transportation are not only cost-effective and environmentally friendly but also offer health benefits. They provide a more active and fun way to travel, helping to improve your physical health and well-being by reducing stress, enhancing concentration, and boosting learning.
To facilitate the use of public transportation, walking, and cycling, cities play a crucial role. Urban planning should focus on creating attractive, well-connected spaces with safe and convenient infrastructure for pedestrians and cyclists. This includes dedicated bike lanes, sidewalks, and safe road and rail crossings.
By choosing to use public transportation, walk, or cycle instead of driving, you can contribute to reducing air pollution, improving your health, and making cities more sustainable and environmentally friendly. These small changes can collectively have a significant impact on the environment and the well-being of communities.

Conserve electricity and use environmentally safe paints and cleaning products
Conserving electricity and using environmentally safe paints and cleaning products are effective ways to reduce air pollution.
Conserve electricity
Using less energy is a great way to conserve electricity and reduce air pollution. This can be achieved by using energy-efficient appliances and heating systems, and turning off electrical appliances when not in use. Energy efficiency has been shown to have a positive impact on air quality, as it reduces the demand for electricity generation, which in turn reduces air pollution. In China, for example, energy efficiency improvements between 2000 and 2014 saved 11% of the total primary energy supply and avoided 1.2 gigatonnes of CO2 emissions in 2014.
Use environmentally safe paints
Traditional paints often contain Volatile Organic Compounds (VOCs) which can emit hazardous air pollutants (HAPs) and contribute to indoor air pollution. Eco-friendly paints, on the other hand, are formulated with low or no VOCs, reducing toxin exposure and improving indoor and outdoor air quality. Some trusted brands offering eco-friendly paints include The Organic & Natural Paint Co., AFM Safecoat, and Benjamin Moore's Eco Spec line. These companies prioritize the use of natural ingredients, safe production processes, and sustainable practices.
Use environmentally safe cleaning products
Conventional cleaning products often contain harmful chemicals that can linger on surfaces and vaporize into the air, causing irritation, allergies, and other health issues. They can also be harmful to the environment, particularly aquatic life, when rinsed down the drain. To reduce these negative impacts, opt for natural and non-toxic cleaning products. Brands such as Dirty Labs and Puracy offer cleaning products that are free of harsh chemicals, biodegradable, and made from natural ingredients.

Avoid burning wood, trash, or other materials
Burning wood, trash, or other materials releases harmful chemicals and particles into the air, causing air pollution and adverse health effects. To avoid contributing to air pollution through burning, consider the following points:
- Avoid burning trash, such as garbage, plastic, old furniture, or construction materials like treated wood products or particleboard. These materials release toxic chemicals and heavy metals, including dioxin, when burned, which can cause serious health issues.
- Do not burn wet, painted, stained, or treated wood. Instead, only burn clean, dry wood with lots of oxygen to reduce smoke and air pollution.
- Comply with local burning laws and regulations. Many places have restrictions on open burning and the types of materials that can be burned. For example, some areas prohibit the burning of garbage, plastics, and other harmful materials in fireplaces and wood stoves.
- Opt for alternative heat sources or cooking methods. Instead of burning wood or trash for warmth or cooking, consider using electric or gas-fueled fireplaces, stoves, or logs. These alternatives produce fewer emissions and are safer for indoor and outdoor air quality.
- Practice proper waste management. Instead of burning trash, focus on recycling, composting, or disposing of waste in designated landfills. Proper waste management can help reduce air pollution and minimize the release of harmful chemicals into the atmosphere.
- Promote the use of clean technologies. Encourage the adoption of advanced combustion technologies, such as EPA-certified wood-burning devices or gas-fueled options, which are designed to reduce emissions and minimize air pollution.
