We spend the majority of our quality time in our homes. So, it's crucial to create a space where the air we breathe is clean and free from harmful pollutants. Indoor air quality (IAQ) refers to the overall condition of the air inside a building and how it affects the health and comfort of its occupants. Poor IAQ can lead to a range of health issues, including allergies, respiratory problems, and even more serious long-term effects.
In this blog, let’s explore various strategies and building material considerations that can help you improve the indoor air quality of your home.
BUILDING MATERIALS FOR CLEAN AIR:
a) Paints and Coatings:
Volatile organic compounds (VOC) are chemicals that can be emitted as gases from certain materials. Choose paints and coatings that are low in VOCs or VOC-free. Traditional paints often release high levels of VOCs, which can contribute to poor indoor air quality. Look for paints labeled as "low VOC" or "VOC-free" to minimise the release of harmful chemicals into the air. Consider natural alternatives like milk paint, clay paint, or lime wash, which are made from non-toxic ingredients.
b) Flooring Options:
Flooring materials can impact indoor air quality significantly. Here are some options to consider:
- Hardwood: Go for solid hardwood flooring that is free from toxic adhesives and finishes. Avoid engineered wood flooring with high formaldehyde content.
- Bamboo: Bamboo is a sustainable and eco-friendly flooring choice. Ensure that it is free from formaldehyde-based adhesives.
- Cork: Cork flooring is made from the bark of the cork oak tree. It is a renewable material that is naturally resistant to mold, mildew, and pests.
- Natural Stone: Natural stone, such as marble, granite, or slate, is an excellent choice as it does not emit harmful substances.
c) Insulation:
Proper insulation helps maintain a comfortable indoor temperature and reduces energy consumption. When selecting insulation materials, consider the following:
- Natural Fiber Insulation: Materials like cotton, wool, and cellulose fiber are eco-friendly options that do not release harmful gases into the air. Ensure they are treated with non-toxic fire retardants.
- Fiberglass Alternatives: If you require fiberglass insulation, choose products that are formaldehyde-free and have a low VOC binder.
d) Cabinets and Furniture:
When selecting cabinets and furniture, look for those made from solid wood or formaldehyde-free pressed wood products. Formaldehyde emissions are common in certain types of pressed wood furniture and cabinets. Ask for products certified as compliant with recognized standards for low formaldehyde emissions, such as the California Air Resources Board (CARB) Phase 2 standard.
e) Natural and Organic Materials:
Consider using natural and organic materials throughout your home, such as untreated wood, natural fabrics, organic bedding, and natural fiber rugs. These materials are less likely to emit harmful chemicals into the air and promote a healthier indoor environment.
PROPER VENTILATION:
Good ventilation is the key to maintaining a healthy indoor environment. It helps to remove stale air and pollutants, replacing them with fresh outdoor air. Ensure your home has an effective ventilation system, such as properly sized exhaust fans in kitchens and bathrooms, and consider installing a whole-house ventilation system for continuous air exchange.
AIR FILTRATION AND PURIFICATION:
- HVAC Filters: Regularly clean or replace HVAC (Heating, Ventilation, and Air Conditioning) filters to ensure they effectively capture dust, allergens, and other airborne particles. Opt for high-efficiency filters with a Minimum Efficiency Reporting Value (MERV) rating of 8 or higher.
- Air Purifiers: Consider using standalone air purifiers with HEPA (High-Efficiency Particulate Air) filters to remove fine particles, allergens, and even odors. Place them strategically in areas where you spend the most time, such as bedrooms or living rooms.
CONTROLLING HUMIDITY:
Excessive humidity can lead to mold growth and the proliferation of dust mites. Use dehumidifiers in damp areas like basements, bathrooms, and laundry rooms to maintain optimal humidity levels (around 30-50%).
REGULAR CLEANING AND MAINTENANCE:
Keeping your home clean is vital for maintaining good indoor air quality. Regularly clean dust, vacuum, and mop floors to reduce the accumulation of dust, pet dander, and other allergens. Clean bedding, upholstery, and curtains regularly to minimize the presence of airborne particles.
By incorporating these strategies and building materials considerations into your home construction, you can create a healthier living space with improved indoor air quality for you and your loved ones.
