Summer in Rhode Island brings warm temperatures and beautiful weather, but it can also introduce challenges for maintaining good indoor air quality. As residents close their windows and rely more on air conditioning, the quality of the air inside their homes becomes a crucial factor in their overall health and comfort. In this blog post, we’ll explore why indoor air quality is especially important during the summer months and provide practical tips to help Rhode Island homeowners maintain a healthy home environment.
Why Indoor Air Quality Matters
Health Implications
Poor indoor air quality can have significant health effects, particularly for vulnerable groups such as children, the elderly, and those with respiratory conditions like asthma or allergies. Common pollutants include dust, pollen, mold spores, pet dander, and volatile organic compounds (VOCs) from household products. Exposure to these pollutants can lead to symptoms such as headaches, dizziness, fatigue, and respiratory issues.
Comfort and Well-being
Good indoor air quality is essential for overall comfort and well-being. Clean air helps prevent stuffiness and unpleasant odors, creating a more pleasant living environment. During the summer, when high humidity levels can exacerbate the growth of mold and mildew, maintaining good air quality is especially crucial.
Energy Efficiency
Maintaining good indoor air quality can also enhance the efficiency of your HVAC system. A clean and well-maintained system operates more efficiently, reducing energy consumption and lowering utility bills. Conversely, a system clogged with dust and debris works harder to cool your home, leading to higher energy costs and potential breakdowns.

Common Indoor Air Pollutants in Summer
Dust and Pollen
Dust and pollen levels tend to increase during the summer months. These particles can enter your home through open windows and doors or be carried inside on clothing and pets. Once inside, they can accumulate in carpets, furniture, and HVAC systems, leading to poor indoor air quality.
Mold and Mildew
High humidity levels during the summer can create ideal conditions for mold and mildew growth. These fungi thrive in damp, warm environments and can spread rapidly, releasing spores into the air that can trigger allergic reactions and respiratory problems.
Pet Dander
During the summer, pets may shed more fur and dander, contributing to indoor air pollution. Pet dander consists of tiny, even microscopic, flecks of skin shed by cats, dogs, rodents, birds, and other animals with fur or feathers. These bits of skin can cause reactions in people who are specifically allergic to these triggers.
VOCs
Volatile organic compounds (VOCs) are chemicals that can be released from household products such as paints, cleaning supplies, and air fresheners. During the summer, higher temperatures can increase the rate at which VOCs are emitted into the air, contributing to indoor air pollution.

Tips for Improving Indoor Air Quality in Summer
1. Regularly Change Air Filters
One of the simplest and most effective ways to improve indoor air quality is to regularly change the air filters in your HVAC system. Air filters trap dust, pollen, pet dander, and other airborne particles, preventing them from circulating throughout your home. During the summer months, when your air conditioner is running frequently, it’s especially important to check and replace filters every 30-60 days.
2. Use a Dehumidifier
High humidity levels can make your home feel uncomfortable and promote the growth of mold and mildew. Using a dehumidifier helps maintain optimal indoor humidity levels, ideally between 30-50%. This not only improves comfort but also reduces the risk of mold growth and other moisture-related issues.
3. Maintain Your HVAC System
Regular maintenance of your HVAC system is essential for ensuring good indoor air quality. Schedule annual inspections and tune-ups with a professional HVAC technician to keep your system running efficiently. This includes cleaning the coils, checking refrigerant levels, and ensuring that all components are in good working order.
4. Use Natural Ventilation
When the weather is mild, consider using natural ventilation to improve indoor air quality. Open windows and doors to allow fresh air to circulate through your home. This helps dilute indoor pollutants and brings in cleaner outdoor air. However, be mindful of pollen levels and outdoor air quality, as these can affect indoor air quality as well.
5. Invest in an Air Purifier
Air purifiers can be highly effective in removing airborne pollutants from your home. Look for models with HEPA filters, which are capable of trapping small particles like dust, pollen, and pet dander. Some air purifiers also have activated carbon filters that can absorb VOCs and odors.
6. Keep Your Home Clean
Regular cleaning can significantly reduce the amount of dust, pet dander, and other allergens in your home. Vacuum carpets and upholstery with a vacuum cleaner equipped with a HEPA filter, dust surfaces with a damp cloth, and wash bedding and curtains regularly. Keeping your home clean also helps to reduce the overall load on your HVAC system.
7. Control Sources of VOCs
Minimize the use of products that emit VOCs, such as certain paints, cleaning supplies, and air fresheners. Opt for low-VOC or VOC-free products whenever possible. Additionally, ensure good ventilation when using products that may release VOCs, and store them in well-ventilated areas away from living spaces.
8. Address Mold Issues Promptly
If you notice signs of mold growth in your home, address them promptly to prevent further spread and potential health issues. Small areas of mold can often be cleaned with a mixture of water and detergent, but extensive mold problems may require professional remediation.
9. Use Plants to Improve Air Quality
Certain houseplants can help improve indoor air quality by absorbing pollutants and releasing oxygen. Some of the best plants for this purpose include spider plants, peace lilies, and snake plants. Be sure to research which plants are best suited for your home environment and take care of them properly to avoid issues such as mold growth in the soil.
10. Educate Your Family
Finally, educate your family about the importance of indoor air quality and involve them in efforts to maintain a healthy home environment. Simple habits, such as removing shoes at the door to reduce dirt and pollen, can make a big difference. Encourage everyone to contribute to keeping the home clean and well-ventilated.

Conclusion
Maintaining good indoor air quality during the summer months is crucial for the health, comfort, and well-being of Rhode Island homeowners. By understanding the common indoor air pollutants and taking proactive steps to reduce them, you can create a healthier living environment for you and your family. From regular HVAC maintenance and using air purifiers to controlling humidity and addressing mold issues, there are many strategies you can implement to ensure your home’s air is clean and safe. Prioritizing indoor air quality not only enhances your quality of life but also protects your home and your loved ones from potential health risks.
