What You'll Learn
Avoid products containing formaldehyde
Formaldehyde is a chemical widely used in building materials and household products. Exposure to formaldehyde may cause adverse health effects, including irritation of the skin, eyes, nose, and throat. High levels of exposure may cause some types of cancers. To prevent formaldehyde pollution, it is important to avoid products that contain this chemical. Here are some ways to avoid products containing formaldehyde:
When purchasing pressed wood products, look for those that are labelled as compliant with ANSI or California Air Resources Board Air Toxics Control Measure (CARB- ACTM) standards. These products have met certain standards that limit the amount of formaldehyde released. Avoid using plywood and particle board that do not comply with federal standards.
Choose cosmetics and personal care products carefully. Read labels and avoid products containing formaldehyde, quaternium-15, dimethyl-dimethyl (DMDM) hydantoin, imidazolidinyl urea, diazolidinyl urea, sodium hydroxymethylglycinate, and 2-bromo-2-nitropropane-1,3-diol (bromopol). Opt for nail products labelled as formaldehyde-free or "toxic-trio-free." Be cautious with hair-smoothing products, especially those sold in salons, as they are exempt from labelling laws. Avoid using expired cosmetic products or storing them in sunlight, as this can increase the release of formaldehyde.
Be mindful of household products. Formaldehyde is found in glues, permanent press fabrics, paints and coatings, lacquers and finishes, paper products, dishwashing liquids, fabric softeners, fertilisers, and pesticides. Choose products labelled as 'no' or 'low' VOC or formaldehyde.
Consider alternatives to smoking and combustion sources. Formaldehyde is produced when burning natural gas, kerosene, gasoline, wood, or tobacco. Avoid smoking indoors, and ensure that combustion sources, such as stoves or heaters, are properly maintained and vented outdoors.
By following these guidelines and being mindful of product ingredients, you can effectively reduce your exposure to formaldehyde and minimise its impact on your health and the environment.

Ventilate your home
Ventilating your home is a simple and effective way to reduce formaldehyde levels. Formaldehyde is a colourless, flammable gas commonly found in indoor environments, and it can cause adverse health effects, including irritation to the skin, eyes, nose, and throat. In some cases, high levels of exposure to formaldehyde may even cause cancer.
To ventilate your home effectively, increase the supply of fresh air by opening windows, especially when using products that may contain formaldehyde, such as cleaners, paints, or cosmetic products. You can also use exhaust fans to blow indoor air out and bring fresh air in. Central ventilation systems, such as a furnace air exchanger, can also be used to improve indoor air quality.
When bringing new sources of formaldehyde into your home, such as new furniture or pressed-wood products, it is essential to air them out before installing or using them indoors. This process, known as off-gassing, involves removing the packaging and allowing the products to air out for a few days. You can also ask the manufacturer to leave the product unsealed for a few days before delivery or consider purchasing floor models where chemicals have already off-gassed.
Additionally, avoid smoking or vaping tobacco, marijuana, or e-cigarettes indoors. Secondhand smoke contains formaldehyde and other harmful chemicals. If you use combustion sources, such as gas or wood-burning stoves, ensure they are properly maintained, vented outdoors, and checked annually by a professional to prevent leaks.
By following these ventilation tips, you can effectively reduce formaldehyde levels in your home and improve your indoor air quality, creating a healthier living environment for you and your family.

Control heat and humidity
The release of formaldehyde is accelerated by heat and humidity. To reduce formaldehyde emissions, lower the temperature and humidity in your home through air conditioning and dehumidification. Dehumidifiers can help control or reduce humidity and maintain a moderate temperature, but be sure to drain and clean the dehumidifier collection trays frequently so they do not become a breeding ground for microorganisms.
Formaldehyde is a colourless chemical with a strong pickle-like odour that is commonly used in many manufacturing processes. It easily becomes a gas at room temperature, which makes it part of a larger group of chemicals known as volatile organic compounds (VOCs). When an item gives off formaldehyde, it is released into the air through a process called off-gassing.
Formaldehyde is a chemical used in the production of adhesives, bonding agents and solvents. For this reason, it is commonly found in a variety of consumer products, including pressed-wood products (plywood, particleboard, panelling), foam insulation, wallpaper, paints, synthetic fabrics, and cosmetics and personal products.
Formaldehyde is also a byproduct of combustion. When burning natural gas, kerosene, gasoline, wood, or tobacco, formaldehyde is produced. Indoor sources of formaldehyde may be combustion processes such as smoking, heating, cooking, or burning candles or incense.
To minimize exposure to combustion by-products, including formaldehyde and carbon monoxide, ensure that combustion sources are properly maintained and vented outdoors. Avoid smoking indoors.

Avoid smoking indoors
Smoking indoors is a major source of formaldehyde pollution, and it is essential to avoid this practice to prevent formaldehyde pollution and protect your health.
Formaldehyde is a colourless, volatile chemical with a strong odour that is commonly found in various consumer products, including pressed-wood products, paints, adhesives, and cosmetics. It easily becomes a gas at room temperature, and when released into the air, it can cause indoor pollution. While formaldehyde is present both indoors and outdoors, the levels are typically much higher indoors.
Tobacco smoking indoors is a significant source of formaldehyde. When tobacco is burned, it releases formaldehyde, and both the smoker and those exposed to secondhand smoke inhale higher levels of the chemical. In fact, indoor concentrations of formaldehyde can reach more than 200 μg/m3 close to someone who is smoking in a room.
To prevent formaldehyde pollution and reduce your exposure, it is crucial to avoid smoking indoors. This includes not only traditional tobacco smoking but also vaping, as some vaping liquids may contain formaldehyde. By refraining from smoking or vaping indoors, you can significantly decrease the levels of formaldehyde in your indoor environment and reduce the potential health risks associated with formaldehyde exposure.
In addition to avoiding indoor smoking, it is also advisable to choose low-formaldehyde products when building or remodelling. Look for products labelled as 'no' or 'low' VOC (volatile organic compounds) or formaldehyde. Furniture and pressed-wood board made with laminated surfaces generally release fewer formaldehyde emissions. Additionally, proper ventilation is essential. Open windows or use exhaust fans to bring in fresh air and dilute any formaldehyde pollutants.
