Healthy Indoor Air Prong #1: Source Control - Nip It in the Bud

Think of this as the foundation for a healthy home. The key is to minimize the sources of indoor air pollution in the first place. Here's where choosing non-toxic building materials becomes crucial.

Chemicals of Concern:

• Volatile Organic Compounds (VOCs): These are organic chemicals that easily evaporate at room temperature. They're found in paints, adhesives, sealants, carpeting, furniture, and cleaning products. Common VOCs include formaldehyde, benzene, toluene, and xylene.

• Formaldehyde: This gas is a known carcinogen and can irritate the eyes, nose, and throat. It's found in pressed wood products like plywood, MDF (medium-density fiberboard), and some laminates. Flooring, walls, cabinets, furniture, etc. can all contain formaldehyde.

• Flame Retardants: Added to furniture and building materials to slow the spread of fire, some flame retardants have been linked to endocrine disruption and developmental problems.

Common Sources of Toxic Contaminants:

• Building materials: As mentioned earlier, conventional building materials like plywood, MDF, carpets, paints, adhesives, and sealants often off-gas VOCs.

• Cleaning products: Many conventional cleaning products are loaded with harsh chemicals that contribute to indoor air pollution.

• Personal care products: Fragrances and other chemicals in deodorants, air fresheners, scented candles, and more can release VOCs into the air.

• Mold and mildew: Growth of mold and mildew can release allergens and irritants into the air.

Healthy Indoor Air Prong #2: Ventilation - Let the Fresh Air In!

This is the simplest and most affordable way to improve your indoor air quality. Open those windows and doors and let the fresh air circulate. It dilutes indoor pollutants and brings in oxygen, your body's best friend.

Pro Tip: Before throwing open the windows, check your local air quality with a free app like AirNow. You don't want to be exchanging fresh air for polluted outdoor air! This is especially pertinent if you live in a densely populated area.

When building from the ground up, we recommend an energy recovery ventilator (ERV). These systems work by continuously exchanging indoor and outdoor air while regulating temperature and humidity for overall energy conservation.

Healthy Indoor Air Prong #3: Filtration - The Extra Layer of Protection

Ideally, by controlling the source of contaminants and ventilating regularly, you'll minimize the need for air filtration. However, let's be real, we can't control everything. So, air filters can provide an additional layer of protection.

Air Purifiers:

While air purifiers can be quite effective, they can also get pricey. Consider them when source control and ventilation alone aren't enough. Look for air purifiers with HEPA (High Efficiency Particulate Air) filters to capture dust, pollen, and other allergens and a carbon filter for VOC capture. A fantastic and semi-affordable option to consider is Air Doctor.

HVAC Filters:

A more affordable option is to upgrade your HVAC system's air filter. The American Lung Association recommends a MERV (Minimum Efficiency Reporting Value) rating of 13 or higher for capturing smaller particles. However, keep in mind that older HVAC systems might struggle with the increased resistance of a higher-MERV filter. It's always best to consult with an HVAC professional to ensure your system can handle a higher-rated filter without compromising airflow or efficiency.

Here are some additional things to consider when choosing an HVAC filter:

• Filter Size: Make sure the filter you choose is the correct size for your HVAC system.

• Replacement Schedule: Change your air filter regularly, typically every 1-3 months depending on the filter type and your environment. When remodeling, you need to replace more frequently as there are more contaminants to filter from construction.

• Filter Pleats: Opt for pleated filters as they offer more surface area for capturing dust and allergens compared to flat filters. The 3M Filtrete 1900 is a high MERV filter with many positive reviews stating the pleats helped their HVAC system tolerate the increased MERV rating.

• Thickness: A filter with a higher MERV is often better tolerated when 4-5 inches in thickness as opposed to 1 inch.

More Tips For Healthy Indoor Air

Now that you're armed with this three-pronged approach, let's explore some additional steps you can take to improve your indoor air quality:

• Invest in Houseplants: Certain houseplants act as natural air purifiers by absorbing VOCs and other pollutants. Snake plants, spider plants, and peace lilies are all excellent choices.

• Reduce Humidity: Mold and mildew thrive in damp environments. Maintain a healthy humidity level between 30% and 50% with a dehumidifier if necessary. An ERV will also help regulate humidity.

• Minimize Dust Collectors: Clutter and textiles harbor dust and allergens. Opt for minimal hard surfaces and choose washable rugs and furniture fabrics.

• Regular Vacuuming: Vacuum carpets and rugs regularly with a HEPA filter vacuum to trap dust and allergens.

• Take Off Your Shoes at the Door: Shoes can track in MANY pollutants from the outdoor world. Encourage a "no shoes inside" policy to reduce dirt and allergens.

• Let New Furniture Air Out: New furniture can off-gas VOCs. Allow new furniture to air out in a well-ventilated space for several days before bringing it indoors.

Why Children Are More Vulnerable To Toxic Home Builds & Remodels (And What To Do About It!)

Children depend on adults for everything, including protection from environmental threats. While building or remodeling your home is exciting, what if it puts your children's health at risk?  Unfortunately, hidden toxins in paint, flooring, water, air, and elsewhere can pose a serious threat to developing bodies.

This blog explores the unsettling truth regarding children’s increased vulnerability to environmental toxins common in home builds and remodels.  Unlike adults, their organs and immune systems are still under construction, making them less equipped to fight off these harmful substances. 

Here's what you'll learn:

• Why children are anatomically, physiologically, and behaviorally more susceptible to toxins during a home build or renovation.

• Where toxins like lead, mercury, arsenic, formaldehyde, and VOCs may lurk in your home.

• Tips for protecting children during construction: Gain actionable advice on open communication with contractors, lead testing, limiting exposure, ventilation strategies, and choosing safe building materials.

• How to take action and create a safe, healthy home for your little ones.

Why are children more vulnerable to environmental toxins? 

Children's bodies are still developing.  Their organs and immune systems are immature and less equipped to detoxify and eliminate harmful substances.  Additionally, their behavior and physiology put them at a higher risk of exposure .

Understanding Anatomy, Organ Immaturity, and Behavior:

• Respiration: Compared to adults, children breathe more air in proportion to their body weight. This means they inhale more dust, chemicals, and other pollutants present in the air.

• Increased Hand-to-Mouth Activity: Young children explore the world through their mouths, putting them at risk of ingesting dust, lead paint chips, or other contaminated objects.

• Skin Absorption: Children's skin is thinner and more permeable, allowing toxins to enter the bloodstream more readily through contact.

• Developing Organs: Organs like the brain, lungs, and immune system are still maturing in children. These organs are less equipped to eliminate toxins and more susceptible to lasting negative effects.

• Higher Water Intake: Children also have a proportionately larger daily water intake. This means they may ingest more contaminants present in drinking water.

• Behavioral Considerations: Children's curiosity and tendency to explore their environment can put them at an additional disadvantage.  They might not understand the dangers of lead paint chips or contaminated dust, increasing their risk of accidental ingestion.

Where Might Toxins Be Found in Your Home Build or Remodel?

• Lead:

  • Primary Concern: Lead paint.

  • Locations: Homes built before 1978 may have lead-based paint on walls, trim, doors, and even window sills. Lead dust can also be created during renovation projects that disturb lead paint.

• Mercury:

  • Primary Concern: Fluorescent bulbs and certain thermostats.

  • Locations: Older fluorescent bulbs can contain mercury. Consider using LED alternatives during a remodel. Some older thermostats may also contain mercury.

• Arsenic:

  • Primary Concern: Treated wood and contaminated soil.

  • Locations: Arsenic-treated wood can be used for decks, fencing, or even some types of landscaping timbers. Settling dust from contaminated soil can enter your home.

• Formaldehyde (this one is a biggie in construction):

  • Primary Concern: Pressed wood products, adhesives, and some insulation materials.

  • Locations: Particleboard, plywood, and MDF (medium-density fiberboard) are all common building materials that can emit formaldehyde. These are often used in cabinets, furniture, and flooring. Urea-formaldehyde adhesives are used in some plywood and particleboard products. Spray foam insulation can also off-gas formaldehyde. (Check out this blog post on non-toxic insulation.)

• Volatile Organic Compounds (VOCs):

  • Primary Concern: Paints, stains, varnishes, adhesives, and cleaning products.

  • Locations: During construction or remodeling, VOCs can be emitted from these products as they dry or cure. Opting for low-VOC alternatives can significantly reduce exposure.

How To Protect Children During Home Construction and Remodeling

• Open Communication with Your Contractor: Discuss your concerns about environmental toxins and safety from the very beginning. Choose a contractor knowledgeable in low-VOC materials and lead-safe practices (if remodeling an older home). 

• Lead Testing: If your home was built before 1978, have it tested for lead paint by a certified professional. If lead is found, don't attempt to remove it yourself. Hire a lead-abatement contractor who can safely remove the lead paint.

• Limit Time Spent in the Construction Zone: Restrict your children's access to the construction area to minimize their exposure to dust and fumes. Avoid site visits during active construction and keep your kids out of the house during a renovation.

• Check out this previous blog “Should You Live In Your Home While Renovating?”

• Ventilation Is Your Friend: Open windows and doors whenever possible during and after construction to promote air circulation and remove lingering odors. This helps remove dust particles and VOCs that may off-gas from new materials. This is also important to consider when selecting a move-in date for a new home as you want to ensure all materials have completed off-gassing.

• Invest in Safe and Healthy Building Materials: Super important! Work with your contractor to choose low-VOC paints, adhesives, and building materials whenever possible. These products emit fewer harmful chemicals and can create a healthier indoor environment for your family.

Non-Toxic Home-Building: Plywood Edition

https://doveeyesphotography.mypixieset.com/

Welcome back to our continued series on non-toxic home-building! This week we are focusing on a longtime staple in the realm of construction materials: plywood. In the quest for a non-toxic home, it's essential to delve into the world of plywood, considering its uses, the prevalence of OSB (Oriented Strand Board), the potential dangers of off-gassing, and how to make choices that align with your health-conscious goals.

Uses of Plywood in Home Construction

Plywood is a versatile material, often employed in sheathing, flooring, and roofing. Its layers of thin wood veneers glued together create a robust and durable panel, providing structural integrity to various elements of your home.

OSB vs. Plywood: A Shift in Preference for a Non-Toxic Home

In recent years, Oriented Strand Board (OSB) has gained popularity as a substitute for plywood. However, it's crucial to acknowledge that OSB might not be the healthiest choice due to concerns related to off-gassing and toxicity.

Dangers of OSB and the Importance of Structurally Approved Plywood

OSB, while structurally sound, can pose risks in terms of off-gassing. Off-gassing is the release of volatile organic compounds (VOCs), and in the case of OSB, formaldehyde is a key player. To ensure a healthier living space, opting for structurally approved plywood for sheathing becomes paramount.

Why emphasize structurally approved? Soy-based glues and bamboo forms of plywood are growing in popularity as the more health and environmentally-conscious options. However, these types are not structurally approved for sheathing, decking, flooring, etc. They are best used for furniture and cabinets. Make sure to use plywood approved for external and structural use for a long-lasting, durable home.

Understanding Urea Formaldehyde vs. Phenol Formaldehyde

Plywood and OSB contain adhesives, and understanding the types of adhesives used is crucial. Urea formaldehyde, a common adhesive, can release formaldehyde over time. In contrast, phenol formaldehyde is a safer alternative, known for lower emissions.

Recommended Brands of Non-Toxic Plywood

Selecting the right plywood involves considering not just the material but also the brand. Some reputable brands prioritize non-toxicity and sustainability. Researching and choosing wisely can align your construction with your commitment to a healthier home.

Both Weyerhaeuser and Roseburg manufacture plywood with phenol formaldehyde which can be purchased locally from lumber yards.

Warm and Humid Climates: A Challenge for Plywood Off-Gassing

Warm and humid climates can accelerate formaldehyde off-gassing from plywood. This is particularly relevant in our South Texas climate. The combination of higher temperatures and humidity levels facilitates chemical reactions, leading to the breakdown of formaldehyde molecules and their release into the air. In such conditions, the wood fibers in the plywood may swell, creating spaces for formaldehyde to escape more easily.

Tips to Minimize Off-Gassing in Warm and Humid Climates:

Ventilation: Ensure proper ventilation by opening windows and doors to allow fresh air circulation.

Acclimation: Allow plywood to acclimate to the climate before use by storing it in the installation environment for several weeks.

Sealing: Apply a sealant or paint to the plywood to create a barrier, preventing formaldehyde from evaporating into the air. (Make sure the sealant is low-VOC!)

By incorporating these tips into your construction plans, you're taking proactive steps to reduce off-gassing, creating a healthier indoor environment for you and your family. Every choice in construction contributes to the overall well-being of your home.

If you walk away with nothing else from this blog, remember this- use plywood made with phenol-formaldehyde and VENTILATE.

Interior brand: https://475.supply/products/intello-plus

2. Window Flashing

Properly installed waterproof flashing is essential in keeping mold at bay. Flashing is a material that is installed around windows to prevent water from entering the walls. It should consist of a waterproof material, such as metal or rubber.

When installing window flashing, make sure that it extends at least four inches beyond the window frame on all sides. It should also be sloped away from the window to direct water away from the walls.

3. Sealing Openings

Sometimes, the tiniest gaps can cause the biggest troubles. All openings in a home, such as vents, pipes, and electrical outlets, should be properly sealed to prevent moisture from entering and creating an ideal environment for mold growth. Use caulk or sealant to seal around these openings and ensure the seal is tight and durable.

A low-odor caulk: https://www.amazon.com/GE-GE284-Silicone-Kitchen-Squeeze/dp/B000PSE46S/ref=sr_1_4?crid=X8JLJ95XL62O&keywords=ge%2Bsilicone%2B2&qid=1699391197&s=industrial&sprefix=GE%2B2%2B%2Cindustrial%2C179&sr=1-4&th=1
