In any space, a carpet or area rug enhances acoustics and comfort. They absorb sound and provide a soft surface, reducing injury risk from slips or falls. While concerns about dirt and bacteria are valid, choosing the right carpet and maintaining it properly can mitigate these issues. With proper care and regular cleaning, carpets can remain hygienic and contribute to the aesthetic appeal of a room.
What materials are used to make rugs and carpets?
Carpets and rugs are made from fibers that are woven or tufted together, designed to cover and decorate floors in homes, offices, and various other spaces. These fibers can be categorized as either natural carpet materials or synthetic carpet materials.
Natural Fibers:
- Wool: Luxurious, naturally fire-resistant, and stain-resistant. If not maintained properly, it can be susceptible to mold and mildew.
- Sisal: A natural fiber extracted from the agave plant. Sisal offers a beautiful, textured look and is very durable. It feels coarse on bare feet and requires professional cleaning.
- Seagrass: Another natural fiber known for its unique aesthetic and durability. Seagrass is naturally stain-resistant, feels coarse underfoot and fades in direct sunlight.
- Jute: A strong, affordable natural fiber with a golden brown color. Jute is susceptible to moisture damage and staining and feels coarse underfoot.
- Coir: Coir, which is made from the coarse fibers of coconut husks, has natural stain- and water-resistance and may shed some of its fibers over time.
Synthetic Fibers:
- Nylon: Popular synthetic carpet fiber that is durable, stain-resistant, and affordable. Nylon carpet options is susceptible to static build-up.
- Polyester: A budget-friendly fiber with good stain resistance, but lower overall durability, and a tendency to wear more quickly.
- Polypropylene (Olefin): Low-cost carpet fiber that’s highly stain and moisture resistant. Lower-quality grades can, however, be less durable and emit higher levels of VOCs.
- Triexta: A relatively new synthetic fabric that offers superior stain resistance, softness, and durability. Triexta has a higher price, but performance advantages over nylon carpet.
- Acrylic: Affordable and stain-resistant, but less durable than nylon due to wear and tear.
Chemicals And Toxins That May Be Present In Carpets And Rugs
When considering how to pick the right carpet for a healthy indoor environment, understanding the potential chemical content is crucial. Here are some chemicals and toxins that may be present in carpets:
- Formaldehyde: Used in carpet backing and adhesives.
- Volatile Organic Compounds (VOCs): Released from carpet backing, adhesives, and carpet fibers, especially in new carpets.
- Pesticides: Used in carpet manufacturing or cleaning, these chemicals can linger.
- Allergens: Carpets can trap dust mites, pet dander, pollen, and mold spores.
- PFCs (Perfluorinated Compounds): Found in stain-resistant treatments.
- Flame Retardants: Added to meet fire safety standards to slow fire spread.
- Phthalates: Present in synthetic carpet backing.
- Antimicrobials: Used to prevent mold and mildew.
Which Chemicals and Toxins Cause Short-Term Effects, and Which Cause Long-Term Effects?
Chemicals And Toxins With Short-Term Effects:
- Volatile Organic Compounds (VOCs): Respiratory irritation, headaches, dizziness, eye, nose, and throat irritation.
- Formaldehyde: Irritation of the eyes, nose, and throat, coughing, and skin irritation.
- Phthalates: Respiratory issues, skin irritation, and dizziness.
- PFCs (Perfluorinated Compounds): Skin irritation, eye irritation, and respiratory discomfort.
- Flame Retardants: Eye and skin irritation, coughing, and respiratory discomfort.
- Antimicrobials: Skin and respiratory irritation, allergic reactions.
Chemicals And Toxins With Long-Term Effects:
- Formaldehyde: Increased cancer risk, particularly nasopharyngeal cancer; potential respiratory issues and skin irritation.
- PFCs (Perfluorinated Compounds): developmental issues in children, liver damage, and possibly increased risk of cancer.
- Flame Retardants (such as PBDEs): Endocrine disruption, neurodevelopmental delays in children, and increased risk of thyroid problems and cancer.
- Phthalates: Endocrine disruption, reproductive issues, potential developmental issues in children, and respiratory problems.
- Antimicrobials (such as Triclosan): Hormonal disruption, antibiotic resistance, and potential liver toxicity.
These long-term effects highlight the importance of choosing low-toxic or non-toxic carpets and rugs, especially in spaces where long-term exposure is likely. Especially in poorly ventilated spaces, these chemicals can contribute to indoor air pollution and negatively affect health.
For more on improving indoor air quality, consider how ventilation, air purifiers, and low-emission materials play a role.
How to Avoid Exposure and Choose Safer Alternatives
1. Carpet Backing
Avoid:
- Formaldehyde: Carpets and rugs with formaldehyde in the backing or adhesives. Check labels and product specifications to confirm formaldehyde-free options. Look for carpets and rugs with certifications like Green Label Plus, which ensures low formaldehyde emissions.
- Phthalates: once commonly used to soften vinyl carpet backing, have been linked to health concerns. While their use has decreased due to regulations, they still pose a potential risk. To minimize exposure, opt for carpets with natural fibers or those explicitly labeled “phthalate-free.” Look for certifications like GREENGUARD and OEKO-TEX, which often indicate lower chemical emissions and phthalate absence. Additionally, avoid synthetic carpets with vinyl backing and prioritize products labeled “vinyl-free.”
2. Stain & Water Resistant Treatment
Avoid:
- Perfluorinated compounds (PFCs), often dubbed “forever chemicals,” are commonly used to create stain- and water-resistant finishes for carpets and other products. Despite their effectiveness, PFCs pose severe health risks and wreak havoc on the environment, as they are notorious for accumulating in water, soil, and the human body.
- Identifying PFCs can be challenging as manufacturers often omit this information. However, excessive water repellency, claims of permanent stain protection, and synthetic materials can indicate their presence.
Safer Alternatives:
- Certifications: GREENGUARD GOLD carpets mean low chemical emissions, including PFCs.
- Natural Fibers: Choose wool, cotton, or jute carpets, which require little chemical treatment.
- Natural vs. Synthetic Coatings: Although synthetic coatings offer better water and stain resistance, they emit harmful fumes, lose effectiveness over time, and require reapplication. Comparatively, natural coatings like beeswax, lanolin, and wool fat-based sprays are more breathable and environmentally friendly but may need more frequent application and provide less comprehensive protection.
- Washable Rugs: Washable rugs eliminate the need for stain-resistant treatments entirely. Use them in high-traffic or spill-prone areas, and place doormats at entryways while removing shoes to minimize dirt and moisture.
3. Flame Retardant Treatment on Carpets and Area Rugs
Flame retardant treatments are chemicals applied to carpets and rugs to slow down the spread of fire. While intended to improve safety, these treatments have become increasingly controversial for many potential hazards. Critics argue that in the event of a fire, the fumes released from burning flame retardants can be more harmful than the fire itself, posing serious health risks and making survival more difficult.
For example,
- Questionable effectiveness: There’s growing evidence suggesting that these treatments may not significantly increase fire safety, while posing substantial risks.
- Toxic fumes: When exposed to fire, flame retardants release harmful gases, making escape harder.
- Environmental Damage: These chemicals contaminate air, water, and soil, and persist in the environment and continually destroy the ecosystem, accumulating in soil, water, and living organisms, causing long-term damage.
Harmful Effects of Flame Retardants
Flame retardants contain chemicals like (BFRs) and organophosphates, which are linked to serious health issues, including endocrine disruption, neurotoxicity, reproductive problems, developmental delays and cancer.
How to Avoid Flame Retardants:
- Look for Certifications: Choose carpets and rugs certified by organizations such as GREENGUARD GOLD or Cradle to Cradle, which ensure low chemical emissions and safer materials.
- Choose untreated carpets and rugs: choose natural fibers which are inherently more fire-resistant and often require minimal chemical treatments.
For example,
- Wool Carpets: Naturally flame-resistant due to wool’s inherent properties.
- Natural Fiber Rugs: Rugs made from cotton, jute, or hemp, which generally do not require flame retardant treatments.
- Check for Manufacturer Claims: Look for products labeled as “flame retardant-free” or “non-toxic.”
You can ask manufacturers if their products are flame retardant-free, for example:
- Nature’s Carpet: Offers carpets with natural fibers without synthetic flame retardants.
- The Green Building Store: Offers sustainable and non-toxic carpets and underlays free of flame retardants.
- Look for certifications: Purchase carpets with GREENGUARD GOLD, indicating low chemical emissions, including flame retardants.
- Consider washable rugs: These can be easily cleaned and maintained without chemical treatments.
4. Antimicrobials in Carpets and Rugs
What are Antimicrobials?
Antimicrobials are chemicals added to carpets and rugs to inhibit the growth of microorganisms such as bacteria, viruses, fungi, mold, and mildew. These treatments are often marketed as a way to keep carpets cleaner and extend their lifespan, particularly in high-moisture or high-traffic areas.
How to Identify Their Presence
Unfortunately, consumers cannot tell if a carpet or rug contains antimicrobial treatments without specific product information. However, some indicators may suggest their presence:
- Terms: Look for terms like “antibacterial,” “antimicrobial,” “odor-resistant,” or “stain-resistant”, mold or mildew-resistant on the product label.
- Synthetic fibers: Carpets and rugs made from synthetic fibers are more likely to be treated with antimicrobials than natural fibers.
- Price point: Carpets that are more expensive often undergo additional treatments that include antimicrobial agents.
- Certifications and Warnings: Some carpets with antimicrobial treatments may come with certifications or warnings. If the chemical content is not clearly stated, be cautious.
- Manufacturer Information: Ask the manufacturer if their carpets or rugs are antimicrobial-treated.
Health Risks Related To Antimicrobials:
- Our Health: Continual exposure to antimicrobial chemicals can lead to respiratory issues, skin irritation, and other problems such as hormone disruption caused by antimicrobial agents, like triclosan.
- Environmental Health: These chemicals contribute to the development of antibiotic-resistant bacteria which is not a good thing!
In short, as these chemicals seep out of carpets over time, especially through moisture, wear, or when discarded, chemicals gradually “leach” into the surrounding environment throughout the carpet’s lifecycle and cause contamination, which causes:
- Water Contamination: They pollute our rivers, lakes, and groundwater, affecting the safety of drinking water and harming aquatic life.
- Soil Contamination: When antimicrobial chemicals seep into the soil, they disrupt natural ecosystems and harm plants and animals.
- Antibiotic-Resistant Bacteria: Over time, the presence of these antimicrobial chemicals in the environment has led to the evolution of bacteria resistant to antibiotics, making infections harder to treat in humans and animals. This is a huge public health concern, as it can contribute to the spread of “superbugs” that don’t respond to conventional treatments.
How to Avoid and Find Alternatives to Antimicrobials in Carpets and Rugs:
- Choose natural fibers: Opt for carpets and rugs made from natural materials like wool, cotton, or jute. They often have inherent resistance to stains and odors, reducing the need for antimicrobial additives.
- Look for certifications: Some certifications, like GREENGUARD, focus on low chemical emissions, including antimicrobials.
- Select Untreated Options: Choose carpets and rugs with explicit labels stating that they are chemical-free, including antimicrobial treatments. Often, brands that prioritize sustainability provide products that haven’t been treated or have been minimally treated.
- When Selecting Untreated Carpets Use Natural Alternatives: Focus on ventilation and regular cleaning. Good air circulation prevents mold and mildew growth. Regular vacuuming and deep cleaning keep carpets clean without chemicals by effectively removing dirt, dust, and allergens from carpets. Natural deodorizers like baking soda help maintain carpet cleanliness and freshness without the need for antimicrobial treatments.
- Air quality improvement: To improve indoor air quality, use air purifiers that contain HEPA filters.
What certifications can help you choose safe and sustainable flooring?
Independent certifications can help you improve your indoor air quality and the health of your living space in addition to understanding the materials used in carpets and rugs.
Focus on Low-Emission Products:
- FloorScore® Certification: This program verifies that hard surface flooring products meet strict standards for low chemical emissions, minimizing potential health concerns.
- CRI Green Label Plus: This certification program tests carpets for low formaldehyde and VOC (volatile organic compound) emissions. VOCs can contribute to indoor air quality problems and health risks.
GREENGUARD® Certification (Standard and Gold): Similar to FloorScore, GREENGUARD certifies various flooring materials, including carpets, for low chemical emissions. The GREENGUARD Gold standard is even more stringent, making it an ideal choice for those prioritizing very low emissions.
Sustainable and Eco-Friendly Practices:
- LEED v4.1 Certification: While not specific to carpets, LEED (Leadership in Energy and Environmental Design) recognizes FSC-certified wood in green buildings. FSC certification ensures wood comes from responsibly managed forests, promoting sustainability.
- Eco-Friendly Certifications: Look for certifications from organizations like FSC (Forest Stewardship Council) or Green Seal. These programs promote environmentally friendly practices throughout the product lifecycle.
- EPD (Environmental Product Declaration) of the Wool Carpet Organization (WCO): This program provides a detailed report on the environmental impact of wool carpets throughout their lifespan. Understanding a product’s environmental impact allows you to make informed choices that align with your values.
How do different carpet and rug materials compare in terms of cost?
When it comes to carpets and rugs, lower costs often come with higher levels of toxicity. Cheaper materials and manufacturing processes typically involve more harmful chemicals, so investing in higher-quality, eco-friendly options can be better for both your health and the environment in the long run.

Point of Alignment
If you’ve explored the articles on this site, you’ve likely noticed a recurring theme: more and more toxins and chemicals are creeping into our everyday lives, especially in our built environments. It’s overwhelming to think about how much is too much and where to draw the line.
But here’s the thing—being informed gives you the power to make better choices. You can decide where to cut back on these harmful substances, whether it’s in your furniture, paints, finishes, or even carpets. It’s not about avoiding everything, but about knowing where to make healthier choices.
It’s deeply unsettling to realize that something as common as carpets and rugs, which we use every day, can harm both our health and the planet—even when they end up in landfills.
Many carpets, particularly synthetic ones, are treated with chemicals that can take centuries to break down in landfills. As they decompose, they release toxic substances into the soil and water, which can contaminate our local environment and the food we consume.
Synthetic carpets are often made from fibers like nylon, polyester, and polypropylene, which are derived from petroleum. While these materials are durable, affordable, and stain-resistant, they don’t biodegrade like natural fibers such as wool or cotton. Instead, they linger in landfills for an incredibly long time. As they break down slowly, they leach harmful chemicals such as formaldehyde, phthalates, and volatile organic compounds (VOCs) into the environment. These chemicals can contaminate our soil and water, harming wildlife and even entering the food chain, ultimately affecting our health.
The treatments used to make carpets more durable—like flame retardants, stain-resistant agents, and antimicrobials—add another layer of toxicity. While these treatments are meant to make carpets last longer and be easier to maintain, they often release toxic gases into the air over time. As they off-gas, they contribute to poor indoor air quality, which can cause headaches, respiratory issues, and other health problems, especially for those with allergies or sensitivities.
When these carpets and rugs reach the end of their life, they don’t just disappear. They emit methane gas, a potent greenhouse gas, as they decompose. While methane is typically associated with organic waste, synthetic fibers and their chemical treatments also contribute to this issue. Methane worsens air quality and accelerates global warming, making the disposal of these materials an environmental concern that goes beyond just waste.
The combination of harmful chemicals, prolonged decomposition, and the release of greenhouse gases makes synthetic carpets and rugs a serious health and environmental threat. By choosing non-toxic, eco-friendly alternatives, we can help reduce these risks and make a positive impact on both our well-being and the planet.
We’re constantly faced with decisions, such as whether or not we even have access to non-toxic products or the financial and time resources to invest in them. It seems easier to just go with the flow since everyone else seems to be doing the same.
The question isn’t just about carpets, but about the overall toll on our well-being. It’s time to demand change. By insisting on healthier options, we can set new industry standards and ultimately drive down prices.
Let’s advocate for manufacturers to use safer materials in carpets and rugs. Consumers must demand the removal of harmful toxins from these products. These toxins not only endanger our indoor air quality and health but also wreck havoc on the environment.
