Before diving into renovations, the first step in improving indoor air quality is to assess the current state of the air inside your home. This involves measuring various pollutants and understanding where potential issues may lie. A comprehensive air quality assessment includes checking for things such as:
- Particulate Matter: Dust, pollen, mold spores, and pet dander can accumulate in your home and impact air quality.
- Volatile Organic Compounds (VOCs): These are chemicals emitted by paints, adhesives, and other household products that can contribute to indoor air pollution.
- Radon: This colorless, odorless gas can seep into homes from the soil and pose serious health risks.
- Carbon Dioxide (CO2): High levels of CO2 can lead to discomfort and even health problems.
- Humidity Levels: Excess moisture or dry air can both impact your health and comfort.
By having an expert conduct an IAQ assessment or using DIY kits, you can identify pollutants that are most affecting your home and target the renovation strategies most likely to improve your air quality.
Upgrade Your Ventilation System
Proper ventilation is essential in maintaining good indoor air quality. It allows fresh air to circulate while removing pollutants, moisture, and stale air. Renovating your ventilation system can make a significant impact on the air quality in your home.
a. Improve Exhaust Ventilation in High-Humidity Areas
Areas of your home that are prone to high humidity—such as bathrooms, kitchens, and laundry rooms—are also more likely to harbor mold and mildew. Installing or upgrading exhaust fans in these areas will help reduce moisture levels and prevent the growth of mold. When upgrading, opt for high-quality, energy-efficient fans that can effectively ventilate these spaces without driving up energy bills.
b. Install an HRV or ERV System
A Heat Recovery Ventilation (HRV) or Energy Recovery Ventilation (ERV) system can be an excellent addition during your home renovation. These systems work by exchanging stale, polluted indoor air with fresh outdoor air while also conserving the heat or energy from the outgoing air. This helps to improve air quality without wasting energy.
HRVs are especially effective in cold climates where energy conservation is a priority, while ERVs can also manage moisture in more humid climates. Installing one of these systems ensures that fresh air is constantly circulating while maintaining a comfortable temperature and moisture balance inside your home.
c. Ensure Proper Airflow Throughout the House
Another simple yet impactful renovation task is ensuring proper airflow throughout your home. Many homes, especially older ones, may have blocked or inefficient ducts that prevent air from circulating properly. During a renovation, make sure that air vents and ducts are clear of obstructions. Clean existing ducts to remove dust, dirt, and mold. Additionally, consider upgrading to higher-quality air filters that trap more particles and improve air circulation.
Choose Low-Emission and Non-Toxic Building Materials
The materials used during the renovation process can either contribute to or improve indoor air quality. Traditional building materials can emit harmful chemicals that can degrade air quality, particularly in newly renovated spaces. Therefore, one of the most effective ways to improve IAQ is to choose materials that are low-emission and non-toxic.
a. Paints, Varnishes, and Finishes
Many paints and finishes contain volatile organic compounds (VOCs) , which can emit toxic fumes long after application. These chemicals can cause headaches, dizziness, and contribute to respiratory issues. When renovating your home, opt for low-VOC or no-VOC paints and finishes. These products are made with fewer harmful chemicals, resulting in cleaner air.
Additionally, consider using natural, eco-friendly alternatives like mineral-based paints or natural oils for finishing wood surfaces. These options have minimal environmental impact and do not release harmful pollutants into your indoor environment.
b. Flooring Materials
Flooring materials such as carpets, laminate, and vinyl can also contribute to poor indoor air quality. Many of these materials contain VOCs, adhesives, and chemicals that can off-gas into the air over time. When renovating, consider using flooring options that are both non-toxic and easier to maintain:
- Hardwood Flooring: Opt for sustainably sourced hardwood floors that are finished with natural, low-toxicity finishes.
- Bamboo Flooring: Bamboo is a renewable resource and can be an eco-friendly option for flooring.
- Cork Flooring: Cork is another sustainable material that is naturally antimicrobial and helps with noise insulation.
- Tile or Stone: Porcelain tiles or natural stone are durable, easy to clean, and do not off-gas harmful chemicals.
By opting for natural, low-emission flooring options, you can greatly improve air quality while simultaneously creating a more sustainable home.
c. Furniture and Upholstery
Just like flooring, furniture and upholstery can release VOCs over time. When renovating, choose furniture made from sustainable and low-emission materials. Look for certified organic fabrics for upholstery and avoid synthetic fabrics that can contribute to VOC pollution. Additionally, opt for furniture that is free from harmful flame retardants, which can release toxic chemicals into the air.
Control Humidity Levels
Moisture control is a vital aspect of maintaining good indoor air quality. Excess moisture can lead to the growth of mold and mildew, which can significantly reduce air quality and cause respiratory problems. During your renovation, it’s crucial to address moisture control in both bathrooms and basements to prevent these issues from arising.
a. Use Moisture-Resistant Materials
When renovating bathrooms, kitchens, or any area where water exposure is common, choose moisture-resistant materials such as mold-resistant drywall and waterproof flooring. This will help prevent mold growth, which can be difficult to remove once it takes hold.
b. Install Dehumidifiers and Humidifiers
Maintaining balanced humidity levels can drastically improve indoor air quality. In humid climates, using a dehumidifier can help reduce excess moisture in the air, preventing mold growth and improving comfort. On the other hand, if your home tends to be dry, particularly in the winter, consider installing a humidifier to maintain optimal moisture levels in the air. This will help prevent dry skin, respiratory irritation, and static electricity.
c. Regularly Inspect and Maintain Plumbing Systems
During a renovation, it’s important to ensure that your plumbing system is in good condition to prevent leaks, standing water, and potential mold growth. Regularly check for leaky pipes and other water issues in areas like basements, crawl spaces, and attics. Properly maintaining your plumbing system will reduce the chances of water damage and the growth of mold and mildew.
Invest in an Air Purification System
Another highly effective way to improve indoor air quality is by investing in an air purification system. Air purifiers work by removing harmful particles such as dust, allergens, mold spores, and pet dander from the air. If you’re dealing with specific air quality concerns like allergens or smoke, a well-chosen air purifier can provide immediate relief.
a. HEPA Filters
When selecting an air purifier, look for models that feature HEPA filters (High-Efficiency Particulate Air). These filters are capable of capturing 99.97% of airborne particles that are 0.3 microns or larger, including dust, pollen, and pet dander. HEPA filters are ideal for individuals who suffer from asthma, allergies, or other respiratory conditions.
b. UV-C Light Air Purifiers
UV-C light air purifiers use ultraviolet light to kill bacteria, viruses, and mold spores that may be present in the air. These systems can be particularly helpful if you have a mold problem or want to ensure that harmful pathogens are neutralized before they can circulate in your home.
c. Activated Carbon Filters
If you’re concerned about volatile organic compounds (VOCs) or odors in your home, consider purchasing an air purifier that uses activated carbon filters. These filters are effective at removing gases and chemicals that can degrade air quality.
Regular Maintenance and Cleaning
Maintaining a clean and well-maintained home is key to improving indoor air quality. Regular cleaning helps reduce the accumulation of dust, pet dander, and other pollutants that can affect air quality. In addition to cleaning your home, ensure that HVAC systems, air purifiers, and air filters are cleaned or replaced regularly.
