Volatile Organic Compounds (VOCs) are chemicals inside paint that are released into the air as you paint a wall. They are dangerous for several reasons: many VOCs are known carcinogens, and they can put you at a higher risk of developing asthma or allergies. While zero-VOC paints are marketed as a healthier alternative, they may still contain other harmful chemicals, such as ammonia, formaldehyde, acetone, or crystalline silica. These chemicals can off-gas, releasing vapors that linger inside homes and affect the quality of the air you breathe. This is especially concerning for individuals who are on oxygen therapy, as they are more susceptible to the harmful effects of indoor air pollution. Therefore, it is crucial for people on oxygen to carefully consider the potential risks associated with zero-VOC paints and take the necessary precautions to ensure their safety.

What You'll Learn
Zero-VOC paints can still contain harmful chemicals
Zero-VOC paints are an improvement over the lead-based paints of previous generations and the high-VOC paints that were common in the past. Zero-VOC paints do not contain added VOC chemicals, and they may only contain trace amounts of VOCs, if any. However, zero-VOC paints can still contain harmful chemicals.
While zero-VOC paints may not contain added VOCs, they can still have other dangerous chemicals. For example, some zero-VOC paints may include ammonia, which can cause a burning sensation in the eyes and skin and potentially lead to long-term lung damage. Additionally, some paints contain fungicides to prevent the growth of fungus on walls, but these fungicides can off-gas potentially harmful chemicals.
Furthermore, crystalline silica, a chemical ingredient often found in latex paints, is not listed as a VOC but can be breathed in during application, potentially causing lung diseases such as silicosis and even cancer. This highlights the importance of considering other chemicals beyond just VOCs when selecting paint.
When choosing a paint, it is essential to look beyond the marketing claims and investigate the specific ingredients and potential health risks. Regulations around VOCs can vary, and there is no standard list of what constitutes a low-VOC paint. Therefore, it is crucial to review the VOC test data and ingredient lists provided by manufacturers. Certifications like GreenSeal and Greenguard Gold Certified can also help identify paints that meet strict limits on VOC content and emissions.
In summary, while zero-VOC paints are a step in the right direction for reducing harmful chemicals in our homes, they may not entirely eliminate them. Consumers must remain vigilant and informed to make the best choices for their health and well-being.

Off-gassing can cause dangerous indoor air quality
Volatile organic compounds (VOCs) are organic chemical compounds that evaporate under normal indoor atmospheric conditions. They are the invisible chemicals we smell when introducing paint products, building supplies, and even new furniture into our homes.
The danger with VOCs is related to their potential to off-gas or give off vapours that linger inside homes and negatively affect the quality of the air you breathe. Off-gassing can last well after the new paint smell is gone—potentially several years. Many products will off-gas more intensely in the days and weeks after application, and most off-gassing occurs during the first six months after application.
The evaporation process is called "off-gassing," and it releases chemicals such as formaldehyde, d-Limonene, toluene, acetone, and ethanol. Consumers have experienced short and long-term health effects from exposure to VOCs. According to the EPA, VOCs can be up to two to five times higher indoors. VOCs are dangerous for several reasons. Firstly, many VOCs are known carcinogens. A typical bucket of paint contains chemicals such as benzene, methylene chloride, and others that have been linked to cancer. Secondly, VOCs are the components of paint that cause headaches after painting. Lastly, the VOC-rich air in your home over the years can put you or your family members at a higher risk of developing asthma or allergies.
While low-VOC or no-VOC paints are an improvement over the lead-based paints of previous generations, they are not entirely safe. When paint is labelled as low-VOC or no-VOC, it does not mean that the paint is free of other dangerous chemicals. Many paints that brand themselves as low-VOC might include ammonia, which can lead to a burning sensation in the eyes and skin and even cause long-term lung damage. Many paints also include fungicides to prevent the growth of fungus on walls. However, these fungicides can off-gas potentially dangerous chemicals that can be harmful to breathe daily.
To avoid the potential health risks associated with off-gassing, consumers can take several steps. Firstly, choose zero-VOC paints. Brands offering zero-VOC paint don't add VOC chemicals to their mixtures, resulting in a product with only trace amounts, if any. Look for paint companies that meet zero-VOC paint emissions standards (containing 5g/L or less of VOCs) and are willing to disclose their test results. Additionally, ensure that the zero-VOC paint brand doesn't include VOCs in their tinting process, as VOCs can be present in colourants. Consumers should also buy only as much VOC paint as they will use quickly and safely dispose of leftovers to reduce exposure.

Low-VOC paints may be more expensive
Low-VOC paints are more expensive than traditional paints. For example, a brand that sells a gallon of high-VOC paint for $20-$30 might sell a gallon of low-VOC paint for $40-$50. The least expensive paints are usually the paints that contain the most VOCs. Standard VOC paints are usually the cheapest option available.
The higher cost of low-VOC paints is likely due to the extra processes involved in reducing the amount of VOCs in the paint. VOCs, or volatile organic compounds, are organic chemical compounds that evaporate under normal indoor atmospheric conditions. They are the invisible chemicals we smell when bringing paint products, building supplies, and even new furniture into our homes. VOCs can build up in the home and negatively affect indoor air quality. They can also be present in caulk, air fresheners, cleaning products, smoking, carpet, vinyl and composite flooring, dry cleaning, photocopiers, petroleum products, natural gas, upholstery, foam, and wood-burning.
While low-VOC paints are an improvement over lead-based paints and high-VOC paints, they are not completely harmless. Low-VOC paints may still contain other harmful chemicals, such as ammonia and fungicides, which can off-gas and be dangerous to breathe. Additionally, the reduced VOCs in low-VOC paints may result in a decrease in the longevity of the paint, meaning that it will need to be reapplied more often, costing more money in the long run.
However, low-VOC paints have several advantages. They have a lower odor than traditional paints, enabling you to close your windows and return indoors sooner after painting. They also release fewer toxic fumes, making them safer for commercial painting contractors and employees working inside. Low-VOC paints are also more sustainable and less harmful to the environment than traditional paints. Some low-VOC paints, such as Behr Premium Plus Low Odor, are also affordable, water-based, low-odor, and Greenguard Gold Certified for low chemical emissions.

Zero-VOC paints are better for the environment
Zero-VOC paints use water-based formulations instead of chemical solvents. They are much safer for human health and the environment. They have minimal odor, making them ideal for people who are sensitive to harsh smells. Using non-toxic paints reduces the risk of long-term health effects associated with traditional paints. They dry quickly and clean up easily with mild soap and water. These paints can be used in most rooms, including nurseries and bedrooms, without posing any health risks.
However, it is important to note that zero-VOC paints may be more expensive than traditional paints and may require more coats to achieve the same level of coverage. Some zero-VOC paints may still contain small amounts of VOCs, although they are well below the regulated amount. When shopping for zero-VOC paints, look for certifications such as Green Seal, GREENGUARD, or CERTIFIED asthma & allergy friendly.
Some popular zero-VOC paint brands include ECOS, Benjamin Moore, Sherwin Williams, Clare Paint, and Behr. These brands offer a variety of colors and finishes while being environmentally responsible and health-aware.

Some paints contain carcinogens
Paints contain thousands of chemical compounds, including organic solvents such as toluene, xylene, aliphatic compounds, ketones, alcohols, esters, and glycol ethers. While solvent-based paints today contain much less solvent than they did a decade ago, paints can still contain harmful chemicals that pose health risks.
Occupational exposure to paint is classified as a Group 1 carcinogen by the International Agency for Research on Cancer (IARC). This classification is based on increased risks of lung cancer, urinary bladder cancer, and mesothelioma. There is also some evidence of a link between childhood leukaemia and exposure to paint chemicals.
Paint chemicals can cause DNA damage, and the greatest risk is in a workplace setting. Painters should wear masks and other protective gear to avoid exposure and increase ventilation in indoor spaces.
Volatile organic compounds (VOCs) are organic chemical compounds that evaporate under normal indoor atmospheric conditions. They are emitted from thousands of everyday products and materials found in the home, including paint, and can affect indoor air quality. VOCs are regulated by the government due to their ability to cause smog, but they can also have harmful effects on human health.
Zero-VOC paints are available, but they may still contain trace amounts of VOCs, and they are not necessarily free of other dangerous chemicals. When selecting a paint, it is important to read the label and choose products that follow air quality regulations, such as the SQAQMD-113 Regulation or the GreenSeal certification.
