Sources of VOCs and Odors: A Healthy Home Guide

Indoor air quality (IAQ) plays a critical role in maintaining a healthy home environment. Unfortunately, many homeowners are unaware of some of the dangers in their home that could deteriorate their healthy IAQ: volatile organic compounds (VOCs). As a builder or contractor, you can educate them on VOCs and their impact.

Understanding VOCs and Odors and Their Impact on Health

VOCs are gases emitted from various household products and materials. These compounds can have detrimental effects on our health and surrounding environment. Many people believe that if they only use products that emit natural odors, it’s better for their home and health, but that is not true — some natural scents can also release VOCs.

Exposure to these compounds can result in a range of health problems, both short- and long-term. The presence of VOCs in indoor air can lead to various respiratory, neurological, and allergic reactions.

Short-term health concerns

According to the EPA, short-term exposure to high levels of VOCs can cause immediate symptoms such as eye, nose, and throat irritation, headaches, dizziness, and nausea. These symptoms are often referred to as "sick building syndrome," where occupants experience discomfort and health issues when spending time in certain buildings or environments with poor air quality. Anyone with pre-existing respiratory conditions like asthma or allergies may experience worsened symptoms, leading to difficulty breathing and exacerbation of respiratory issues.

Long-term health concerns

While short-term experiences are no laughing matter, it is the long-term exposure to VOCs that poses more serious health risks. Prolonged inhalation of high levels of VOCs has been linked to chronic health conditions such as respiratory disorders like bronchitis and chronic obstructive pulmonary disease (COPD), as well as neurological effects like memory impairment and cognitive difficulties.

Vulnerable populations, such as children and the elderly, are particularly susceptible to the harmful effects of VOCs. Children have developing respiratory and immune systems, making them more prone to respiratory illnesses and long-term health impacts. The elderly often have compromised immune systems and underlying health conditions, making them more prone to the adverse effects of VOC exposure.

It is essential for individuals — especially those in vulnerable groups — to be proactive in minimizing their exposure to VOCs and creating a healthier living environment. Putting measures in place to reduce VOC emissions, improve ventilation, and use low-VOC products can significantly contribute to protecting the health and well-being of everyone at home.

Sources of Volatile Organic Compounds at Home

To create a healthier living environment, it is important to identify and reduce the sources of VOCs in the home. These invisible pollutants can originate from various everyday items and materials. By understanding where these VOCs and odors come from, we can take effective steps to minimize their presence and limit our exposure.

Household cleaning products and chemicals – Common cleaning products, such as aerosol sprays, disinfectants, and even laundry detergents, often contain high levels of VOCs. Switching to eco-friendly alternatives labeled as low in VOCs or fragrance-free can help reduce these compounds in the home.

Paints, varnishes, and adhesives – Traditional paints, varnishes, and adhesives that are used in home projects can release a significant amount of VOCs. Try to opt for low-VOC or zero-VOC options; if you are unable, store the products in areas away from the home like a detached garage or shed.

Building materials and furniture – Construction materials, such as particleboard, plywood, and insulation, can give off VOCs. Additionally, furniture made from synthetic materials and mattresses can contribute to indoor air pollution. Look for products made from low-emission materials and choose solid wood furniture when possible.

Carpets and flooring – Synthetic carpets and certain types of flooring — such as vinyl or laminate — can release VOCs into the air. These types of flooring are made from synthetic fibers that derive from non-renewable petroleum. When you can, opt for low-VOC carpets or natural flooring alternatives like hardwood and tile.

Personal care products and fragrances – Perfumes, shampoos, cosmetics, and other personal care products often contain chemicals that emit VOCs. Switching to non-toxic and fragrance-free alternatives can minimize exposure.

Cooking and combustion appliances - When cooking, gas stoves and ovens produce combustion byproducts and can release VOCs. Ensure proper ventilation in the kitchen by using a range hood or installing a food preparation exhaust fanto reduce indoor air pollution.

How to Reduce VOCs in the Home

It’s nearly impossible to eliminate all chemical pollutants from the home, so additional steps, including mechanical options, are critical to creating a healthier indoor environment. Consider implementing the following measures to help homeowners manage the impace of VOCs:

Improve ventilation - Install a fresh air appliance with your HVAC system and use exhaust fans in kitchens and bathrooms.

Use air purifiers and filters - Air purifiers with activated carbon filters can help trap and remove VOCs and odors from the air. Explore options like Fantech's air filtration systems, specifically designed to improve indoor air quality.

Implement proper cleaning and maintenance practices - Regular cleaning using non-toxic and environmentally friendly products can help reduce VOC levels in your home. Proper maintenance of HVAC systems, including changing filters regularly, is also crucial.

Indoor plants – Certain plants can absorb VOCs and odor-causing compounds, improving a home’s IAQ. Consider incorporating indoor plants like peace lily, spider plants, or Boston ferns, which are known for their air-purifying properties.

By taking proactive steps to limit exposure to VOCs and odors, you can create a healthier living environment. Reducing the sources of VOCs, improving ventilation, using air purifiers and filters, and implementing proper cleaning and maintenance practices are all effective strategies to minimize the impact of VOCs on your home's indoor air quality.
