Choosing Non-Toxic Flooring: Avoiding PFAs and Cancer-Causing Chemicals
In recent years, the awareness of toxic chemicals in household products has grown significantly, with particular concern over Per- and polyfluoroalkyl substances (PFAS) and various cancer-causing chemicals. PFAS, often referred to as “forever chemicals” due to their persistence in the environment and human body, are associated with numerous health issues, including cancer. This article delves into the types of flooring that minimize exposure to these harmful substances, providing a comprehensive guide for choosing the least toxic flooring options for your home.
PFAS are a group of man-made chemicals used in various industries since the 1940s, found in products that resist heat, oil, stains, grease, and water. Common products include non-stick cookware, water-repellent clothing, and certain types of flooring. PFAS exposure has been linked to health issues such as thyroid disease, hormone disruption, immune system effects, and cancers. In flooring, PFAS are typically found in treatments used to make carpets and other flooring materials resistant to stains and water. Additionally, various flooring materials can contain other harmful chemicals, such as volatile organic compounds (VOCs), formaldehyde, and phthalates, which are known for their adverse health effects, including respiratory issues, skin irritation, and carcinogenicity.
To create a healthier living environment, it is crucial to choose flooring options that are free from PFAS and other toxic chemicals. Solid hardwood flooring is a natural, renewable resource that, with proper care, can last for decades. It adds warmth and beauty to any home, but it is essential to ensure that the finishes and sealants used are non-toxic and free from VOCs, such as water-based polyurethane or natural oils. Sustainable harvesting practices should also be considered to minimize environmental impact. Reputable brands like Kahrs, Bona, and Vermont Plank Flooring offer non-toxic options.
Engineered hardwood flooring provides stability and offers the same look and feel as solid hardwood. It is essential to ensure the core layers are made from non-toxic, formaldehyde-free plywood or high-density fiberboard and that the adhesives used are low-VOC. Brands like EcoTimber and Green Building Supply provide engineered hardwood options with non-toxic glues and finishes.
Bamboo flooring is another sustainable option, as bamboo grows rapidly. It is comparable to hardwood in strength and resilience but requires careful selection of non-toxic, formaldehyde-free adhesives and finishes. Maturity at harvest (around five years) is crucial for optimal hardness. Teragren and Plyboo are known for their non-toxic, environmentally friendly bamboo flooring.
Cork flooring, harvested from the bark of cork oak trees, is eco-friendly and comfortable underfoot. Its natural thermal and acoustic insulating properties are advantageous, but water-based, low-VOC finishes should be used to avoid toxic emissions. WE Cork and Natural Cork offer products free from toxic adhesives and finishes.
Linoleum flooring, made from natural materials such as linseed oil, wood flour, and cork dust, is durable and antimicrobial. To avoid toxic emissions, low-VOC adhesives should be used, or click-together linoleum tiles that eliminate the need for adhesives can be considered. Forbo’s Marmoleum is a well-known brand that offers natural linoleum flooring free from harmful chemicals.
Ceramic and porcelain tile are inert materials that do not emit VOCs or other harmful chemicals. They are highly durable and available in a wide range of colors, patterns, and styles. It is important to ensure that the grout used is free from toxic sealants and additives and to choose tiles with a textured surface to prevent slipping, especially in wet areas. Many tiles are inherently non-toxic, but brands like Fireclay Tile and Bedrosians Tile & Stone offer eco-friendly and non-toxic options.
Natural stone flooring is another durable and aesthetically pleasing option. As with other flooring materials, it is essential to use non-toxic, low-VOC sealants and opt for locally sourced stone to reduce environmental impact from transportation. Choosing reputable suppliers that ensure the stone is free from harmful treatments and coatings is crucial.
Natural carpet and rugs provide a soft, warm surface underfoot and are available in a wide range of styles, colors, and patterns. Opting for carpets made from natural fibers like wool, jute, sisal, or organic cotton is important, and it is crucial to avoid carpets treated with stain repellents or flame retardants containing PFAS. Natural or recycled padding materials should be chosen. Earth Weave and Nature’s Carpet offer non-toxic, natural fiber carpets and rugs free from harmful chemicals.
Rubber flooring is extremely durable, resistant to wear and tear, and provides a slip-resistant surface. It is essential to ensure that the rubber is made from natural latex or recycled rubber without harmful additives. Some rubber flooring can have a strong odor initially, so low-emission options should be considered. Brands like ECOsurfaces and Regupol offer non-toxic rubber flooring made from recycled materials.
Even with the safest flooring materials, the installation and maintenance processes can introduce toxic chemicals into your home. It is crucial to choose low-VOC or zero-VOC adhesives and sealants and use natural, non-toxic underlayment materials such as cork or felt. Proper ventilation during and after installation is essential to dissipate any fumes from adhesives, sealants, or finishes. Using non-toxic, eco-friendly cleaning products will maintain your flooring without introducing harmful chemicals.
Certain certifications and labels can help identify products that meet stringent environmental and health standards. GreenGuard indicates that the product has low chemical emissions, and FloorScore certifies that the flooring meets strict indoor air quality standards. Forest Stewardship Council (FSC) certification ensures the wood is sourced from responsibly managed forests, and Green Label Plus certification for carpets and adhesives indicates low emissions of VOCs. Cradle to Cradle certification signifies products that are sustainable and safe for humans and the environment.
Choosing non-toxic flooring is a crucial step in creating a healthier living environment. Opting for materials like solid hardwood, engineered hardwood, bamboo, cork, linoleum, ceramic and porcelain tile, natural stone, natural carpets, and rubber flooring can significantly reduce exposure to PFAS and other harmful chemicals. Additionally, paying attention to the installation process, using non-toxic adhesives and finishes, and maintaining proper indoor air quality will further ensure a safe and healthy home.
By prioritizing non-toxic flooring options, you not only protect your health and the health of your family but also contribute to a more sustainable and environmentally friendly world. As awareness of these issues continues to grow, more manufacturers are likely to offer safer, greener products, making it easier for consumers to make informed choices.
The path to a non-toxic home begins with informed decisions about the materials brought into the living space. By choosing the right flooring, you can create a beautiful, durable, and safe environment free from the risks associated with PFAS and other toxic chemicals.
