Indoor air quality has a direct impact on our health and well-being, and one of the most significant contributors to poor indoor air quality is volatile organic compounds (VOCs). VOCs are harmful chemicals released as gases and can come from common household materials, including paints, adhesives, flooring, and furniture, which can lead to headaches, respiratory issues, and long-term health effects. Fortunately, with the right materials and strategies, you can reduce or eliminate VOCs and create a healthier living environment. In this blog, we’ll explore zero-VOC strategies to help you achieve superior indoor air quality in your home.

What Are VOCs?

Volatile organic compounds (VOCs) are gases emitted from certain solids or liquids and are commonly found in building materials and household products. VOCs can contribute to indoor air pollution and negatively affect air quality. Some common sources of VOCs include:

• Paints, varnishes, and finishes.
• Cleaning supplies and disinfectants.
• Adhesives and sealants.
• Carpets and upholstery.
• Plywood and particleboard.
• Scented products like candles, perfumes and air fresheners.

Prolonged exposure to VOCs can cause a range of health problems, from minor irritations like headaches and dizziness to more serious respiratory and endocrine conditions. To combat these effects, many homeowners are turning to zero-VOC strategies to create healthier indoor spaces.

Zero-VOC Strategies for Superior Indoor Air Quality

1. Choose Zero-VOC or Low-VOC Paints and Finishes

Impact of Conventional Paints:

• Conventional paints and finishes can emit significant levels of VOCs, particularly during the application and drying process. These chemicals can linger in the air long after the project is completed, impacting indoor air quality.

Zero-VOC Solutions:

• Choose zero-VOC or low-VOC paints, stains, and finishes to minimise harmful emissions. Many eco-friendly brands offer zero-VOC products that provide the same durability and aesthetic appeal as conventional options without compromising air quality.
• Look for certifications like GreenGuard, Green Seal or Sensitive Choice, which ensure that the products meet stringent VOC standards.

2. Opt for Natural Flooring Materials

Conventional Flooring Concerns:

• Carpets, vinyl flooring, and certain laminates can release VOCs due to the adhesives and synthetic materials used in their production. These materials often off-gas harmful chemicals that accumulate indoors.

Zero-VOC Flooring Alternatives:

• Choose natural flooring materials like solid hardwood, cork, bamboo, or linoleum, which are naturally low in VOCs. When installing hardwood or bamboo, select mechanical fixings such as nails to avoid harmful emissions.
• Wool carpets or rugs are also excellent options, as they are naturally resistant to dirt and mould and do not require toxic treatments. Again, opt for mechanical fixings (tacks) over adhesives.

3. Use Formaldehyde-Free and Non-Toxic Adhesives

Common VOC Emissions from Adhesives:

• Adhesives used in construction and home improvement projects are common sources of VOCs. Many contain formaldehyde and other harmful chemicals that can off-gas for years after installation.

Non-Toxic Alternatives:

• Choose mechanical fixings wherever possible.
• Select formaldehyde-free and non-toxic adhesives for projects like installing flooring, cabinetry, or countertops if mechanical fixings are not possible. Water-based adhesives are often a safer alternative to solvent-based products, emitting fewer VOCs and improving indoor air quality.

4. Select Solid Wood Furniture

VOC Concerns with Particleboard and MDF:

• Furniture made from particleboard, medium-density fiberboard (MDF), or plywood often contains formaldehyde-based glues that release VOCs over time. These emissions can degrade indoor air quality, particularly in confined spaces.

Zero-VOC Solutions:

• Opt for furniture made from solid wood, which is free from harmful adhesives and synthetic materials. Look for pieces finished with natural waxes and oils or water-based, low-VOC finishes.
• Consider second-hand or vintage furniture, which has likely already off-gassed most of its VOCs.

5. Choose Natural and Organic Textiles

VOC Issues with Synthetic Fabrics:

• Many synthetic fabrics, such as polyester, nylon, and vinyl, are treated with chemicals that can release VOCs. Additionally, some upholstery and bedding products are treated with flame retardants, which can also emit harmful chemicals.

Healthier Textile Choices:

• Choose textiles made from natural fibers like organic cotton, wool, linen, and hemp. These materials are less likely to contain harmful chemicals and contribute to a healthier indoor environment.
• Look for fabrics certified by organisations like GOTS (Global Organic Textile Standard) or OEKO-TEX, which ensure the materials are free from toxic substances.

6. Install Proper Ventilation Systems

Importance of Air Exchange:

• Even with low-VOC materials, maintaining good indoor air quality requires proper ventilation. Without adequate air exchange, indoor pollutants, including VOCs, can accumulate over time.

Ventilation Solutions:

• Install mechanical ventilation systems like heat recovery ventilators (HRVs) or energy recovery ventilators (ERVs) to bring in fresh air while minimising energy loss. These systems help expel stale, contaminated air and introduce clean, filtered air into your home.
• Regularly open windows to allow for natural air exchange, particularly when cooking, cleaning, or completing home improvement projects.
• Use exhaust fans whenever cooking or bathing and open windows a crack to ensure fresh air is being drawn through a clean opening, not leaking through a grimy crack.
• Invest in an air purifier if you live in an area where the “fresh” outside air is likely to be polluted.

7. Use Air-Purifying Plants

Plants as Natural Air Filters:

• Certain indoor plants can help improve indoor air quality by absorbing VOCs and other pollutants. NASA’s Clean Air Study identified several plants that are effective at filtering harmful chemicals like formaldehyde, benzene, and trichloroethylene.

Top Air-Purifying Plants:

• Snake plants, spider plants and peace lilies are all excellent choices for improving indoor air quality. They are low-maintenance and can help reduce indoor pollutants while adding natural beauty to your space.

8. Reduce Use of Household Chemicals and Cleaners

Impact of Conventional Cleaners:

• Many household cleaning products contain VOCs and other harmful chemicals that contribute to poor indoor air quality. Products like air fresheners, bleach, and ammonia-based cleaners can release toxins that linger in the air.

Zero-VOC Cleaning Practices:

• Switch to natural, non-toxic cleaning products that are free from fragrances, VOCs and harsh chemicals. Many eco-friendly brands offer plant-based cleaners that are just as effective as conventional options without compromising air quality.
• Make your own cleaning solutions using simple ingredients like vinegar, baking soda, and essential oils.
• Essential oils should be used with caution, particularly in bathrooms and wet areas, as the oil can penetrate grout and degrade waterproofing under tiles.

Conclusion

Achieving superior indoor air quality through zero-VOC strategies is a vital step toward creating a healthier home. By selecting low-VOC or zero-VOC materials, incorporating natural elements, and ensuring proper ventilation, you can significantly reduce harmful emissions and promote a safer, more comfortable living environment for you and your family.
