What You'll Learn
Ban smoking inside
Smoking indoors is a major source of indoor air pollution. The Environmental Protection Agency has classified secondhand smoke as a Class A carcinogen, which places it in the same category as asbestos, formaldehyde, benzene, and arsenic. Secondhand smoke is responsible for about 3,000 lung cancer deaths per year in nonsmokers, according to the Environmental Protection Agency. It is also linked to other serious health issues such as heart disease, bronchitis, pneumonia, asthma, and ear infections. In children, the effects of secondhand smoke are even more hazardous and can cause sudden infant death syndrome (SIDS), acute respiratory infections, middle ear disease, and more frequent and severe asthma attacks.
To protect your family and yourself from the dangers of secondhand smoke, it is crucial to implement a strict ban on indoor smoking. This means no cigarette smoke should be allowed inside the home. If you are a smoker, step outside for a cigarette break and consider the impact of your smoking on others. If you are a non-smoker, be mindful of the fact that secondhand smoke can seep into your home from neighbouring apartments or common areas in multi-unit residential buildings. Take steps to address this issue by talking to your neighbour or landlord and seeking solutions to reduce smoke exposure.
In addition to the health risks, smoking indoors can also increase the risk of residential fires. Cigarettes are a common cause of fires, and the financial losses due to cigarette-caused fires can be significant. Implementing a smoke-free rule in your home can help eliminate this risk and create a safer living environment.
Furthermore, the pollutants from tobacco smoke can persist in indoor environments long after smoking has taken place. Research has shown that tobacco smoke pollutants can remain on surfaces and in dust for months, even after smokers move out and nonsmokers move in. This means that even if you are not actively smoking indoors, the residual pollution can still pose a health hazard to you and your family. Therefore, it is essential to maintain a consistent ban on indoor smoking to ensure a healthy and safe living space.
By banning smoking inside your home, you can significantly reduce indoor air pollution and create a healthier and safer environment for yourself, your family, and those around you. This simple step can have a substantial impact on your overall well-being and help mitigate the serious health risks associated with secondhand smoke exposure.

Ventilate your home
Ventilating your home is a key way to promote healthy indoor air. Opening windows and doors is an easy way to encourage a good exchange of indoor and outdoor air. However, this may not always be possible due to allergies or extreme temperatures. In such cases, you can increase ventilation by turning on fans or operating window or attic fans when the weather permits. Local bathroom or kitchen fans that exhaust outdoors can also be used to remove contaminants directly from the room and increase the outdoor air ventilation rate.
When engaging in activities that generate high levels of pollutants, such as painting, welding, or cooking, it is particularly important to increase ventilation. You can also use natural ventilation, such as opening windows and doors, in combination with other methods, such as air purifiers, to further improve indoor air quality.
If you smoke, it is best to step outside to keep indoor pollution levels down. However, if you must smoke indoors, make sure to open windows and turn on a fan to help expel toxins before resuming the purifier and closing the windows.
Additionally, gas stoves that are not well-ventilated can increase exposure to harmful gases such as nitrogen dioxide and carbon monoxide. Make sure your gas stove is adequately ventilated with a hood that vents to the outside. Craft supplies should also be used in well-ventilated areas to avoid inhaling harmful fumes.

Store chemicals safely
Storing chemicals safely is an important step in keeping pollution out of your home. Household cleaning supplies are a common cause of indoor pollution, as the harsh chemicals they contain can give off noxious fumes that irritate the nose, mouth, lungs, and skin. These fumes can cause inflammation, making it harder for people with chronic lung conditions to heal from infections and worsening inflammation caused by allergies.
To store chemicals safely, keep them away from living areas. Solvents, glues, and pesticides should be stored out of reach and out of sight, preferably in a locked cabinet or cupboard. Always read the labels on any chemicals you bring into your home, and follow the instructions for proper storage and handling.
Where possible, opt for natural, homemade cleaning products, such as a mixture of white vinegar and water. These alternatives are more environmentally friendly and less likely to cause irritation.
Additionally, it is important to dispose of chemicals safely and responsibly. Check with your local authorities about how to properly dispose of household chemicals and hazardous waste. Many communities have programs in place to help residents safely discard these items.

Use natural cleaning products
Cleaning is essential to maintaining a healthy home, but conventional cleaning products can contain harmful chemicals that can pollute the air inside your home. Volatile organic compounds (VOCs) are commonly found in household cleaning products and can cause chronic respiratory problems, allergic reactions, and headaches. They can also react with other chemicals in the air to form harmful by-products.
To reduce indoor air pollution, opt for natural cleaning products that are free from toxic chemicals and fragrances. Baking soda, for example, is a natural disinfectant that can be used for scrubbing and managing odours. Mixing it with vinegar and water creates a general-purpose cleaner that can be used on hard surfaces, mirrors, and windows. White vinegar and water is another effective natural cleaning solution.
Natural cleaning products reduce the level of VOCs in your home, improving the air you breathe without sacrificing cleanliness or that fresh, clean scent. They also reduce packaging waste and minimise the number of chemicals released into the environment, positively impacting water and air pollution.
When choosing cleaning products, always read the labels and opt for those that do not contain VOCs, fragrances, irritants, and flammable ingredients. Avoid air fresheners altogether, as these often contain harmful chemicals. Warm water and soap can be just as effective as chemical cleaners, especially for simple household cleaning tasks.

Get an air purifier
Air purifiers can be a great way to reduce indoor air pollution. However, it's important to note that an air purifier alone won't remove all indoor air impurities. It should be used in conjunction with other methods, such as adequate ventilation and banning smoking indoors.
When choosing an air purifier, look for one with a HEPA (high-efficiency particulate arresting) air filter. These are the most effective at reducing common indoor air pollutants, such as dust, dander, mould, smoke, and chemicals. It's also important to replace the filters regularly, as recommended by the manufacturer. Most air purifiers recommend replacing the filters every six months.
In addition to choosing the right type of air purifier, it's crucial to use it correctly. Don't rely solely on the purifier's auto-sensor, as these are not always accurate. Instead, double-check that windows are closed and switch the purifier to the highest setting you can tolerate before going to sleep. During the day, running the purifier at a lower setting can be sufficient, but it's important to keep it running continuously to maintain clean air.
If you have a child with asthma or allergies, running an air purifier in their bedroom is advisable. It may not eliminate all allergens and pollutants, but it can help reduce their presence and alleviate some of the symptoms associated with these conditions.
While air purifiers can be beneficial, it's worth noting that they may not be necessary in all cases. Natural ventilation, such as opening windows and doors, can also effectively reduce indoor air pollution. Additionally, plants have been shown to reduce levels of some chemicals in laboratory experiments, but there is currently no evidence that a reasonable number of houseplants significantly impact indoor air quality.
