Many products we use in our homes, as well as activities we participate in, could seriously contaminate the air we breathe, putting our health at risk. Today, we’re providing you with the top known causes of indoor air pollution and how you contribute to them.
Mold and Mildew
Mold and mildew thrive in damp, humid areas in your home, such as the bathroom and basement. They produce mycotoxins, which affect the muscles. Whether it’s the mold itself or the spores it releases into the air, this fungus is also known to cause respiratory issues and allergic reactions.
Pesticides
We learn from America’s EPA that pesticides contain hazardous air pollutants (HAPs) and VOCs. Pesticides are highly concentrated pollutants that don’t just affect you indoors but can also cause damage to whole neighborhoods and communities. Long exposure to some can lead to vomiting, diarrhea, muscle spasms, cancer, and even death.
Tobacco Smoke
You don’t need to smoke tobacco to be affected by it, as second-hand exposure to its smoke poses health risks, especially to children and pets. Tobacco smoke contains a high concentration of harmful fine particle matter, chemicals, and carcinogens that settle on furniture or linger in the air for up to four hours.
Household Cleaning Products
Many cleaning, sanitizing, and disinfecting products we use at home contain volatile organic compounds (VOCs) that evaporate into the air and cause problems like headaches, respiratory issues, and eye irritation. Fragranced products additionally contain phthalates, which are associated with hormonal disruptions.
Pet Dander
Even our lovely pets at home can seriously deplete indoor air quality because of the dander they release. Dander refers to the tiny particles of skin shed by pets that settle on carpets, upholstery, and bedding—the very particles that make someone allergic to dogs or cats.
Cooking and Cooking Appliances
Gas stoves release carbon monoxide and nitrogen dioxide into the air, causing pollution 400% higher than when you use electric stoves to cook. While odorless and colorless carbon monoxide inhibits oxygen intake, nitrogen dioxide can damage our respiratory tract and cause existing respiratory problems.
Air Fresheners
As the The WP shares, “whether it’s an aerosol bottle, plug-in, oil, scented candle, or gel, if a product promises to clear smells, chances are it harbors toxins that pollute indoor air quality.” The chemicals in deodorizers used to generate fragrances are VOCs that could worsen asthma and other respiratory issues.
New Furniture and Carpets
When you’re buying new carpets or furniture, you have to make sure they aren’t produced using harmful chemicals like formaldehyde. Formaldehyde is a known irritant to our skin and respiratory tract that could cause dizziness and burns. Emissions from carpets and furniture could last for months after your purchase.
Paints and Solvents
Paints are also popular vectors for VOCs like formaldehyde and benzene, which are released into the air as they dry up. These can cause headaches, nausea, and dizziness almost immediately after inhalation, and a lack of ventilation worsens exposure. Thankfully, low—and zero-VOC alternatives exist, so you should go for them.
Personal Care Products
While fragrances from them are primary concerns, an NIH paper explains how personal care products (PCPs) also release biologically active and inactive ingredients into the air. If you’d like to protect the atmosphere and your own health, it’s best to use natural, fragrance-free products.
Dust
It isn’t the dust itself we have to worry about, but the dust mites they harbor. Dust mites are tiny, insect-like pests that accumulate in carpets, bedding, upholstered furniture, and even HVAC filters, causing allergic reactions and possibly triggering asthma. One excellent way to control them is to always use HEPA filters in your home.
HVAC Systems
Sometimes, even HVAC systems with the preferred HEPA filters cause indoor air quality to derail, and this happens when they are not maintained well. HVAC systems harbor bacteria and viruses when they’re not cleaned regularly, and they also circulate harmful substances like dust and mold while they work.
Fireplaces
According to the Guardian, fireplaces and any apparatus used to burn wood to stay warm indoors are also significant sources of indoor air pollution. By using them, you release tiny wood particles into the air, which are particularly harmful to older and younger people.
Radon Gas
Randon is a naturally occurring radioactive gas that the WHO tells us is found in high concentrations in homes and workplaces. It typically seeps into the home through its foundation, especially homes built over uranium. Radon gas is one of the leading causes of lung cancer.
Candles and Incense
Candles, especially those with lead wicks, can also release lead into the air at levels the EPA recommends against. Incense smoke, when inhaled, is known to cause respiratory dysfunction by polluting the airways with particulate matter, harmful gases, and other organic compounds.
Building Materials and Insulation
When we talk about building materials, the most dangerous are asbestos and fiber glass, which release harmful fumes and tiny particles into the air. Some wood materials also contain formaldehyde, while adhesives, solvents, and mastics could emit VOCs at dangerous levels.
Construction and Renovation Activities
Now, separate from the construction materials themselves, there are other things you come in contact with during demolition or rebuilding operations. Disruptions caused by construction work expose us to irritants and harmful materials like mold, lead, and even bird waste, increasing particles in the air by over 20%.
