Indoor air quality (IAQ) refers to the air quality within and around buildings, and good indoor air quality is often overlooked even though it plays a significant role in your overall health, comfort, and energy efficiency. With most people spending 90% of their time indoors, indoor air can be more polluted than outdoor air, so the air inside your home has a direct impact on respiratory diseases, allergies, sleep, and overall well-being.
Improving indoor air quality starts with small habits and the right home comfort solutions. Regular HVAC maintenance, clean air filters, proper ventilation, humidity control, and air purification can all help reduce dust, allergens, pet dander, mold spores, and other airborne contaminants that affect indoor air quality. By taking a proactive approach, you can create a healthier indoor environment, breathe easier, and keep your heating and cooling system running more efficiently throughout the year. Understanding the factors that contribute to poor IAQ is essential for effective improvement. Additionally, considering the impact of outdoor air quality and human activities on your indoor environment can guide better IAQ services and maintenance strategies.
The good news? You don’t need to spend a fortune to make a meaningful improvement. Here are some simple, practical tips for improving your indoor air quality—most of which you can begin implementing today.
1. Replace or Upgrade Your Air Filters Regularly
One of the easiest and most effective ways to boost your indoor air quality is by replacing your HVAC air filters regularly, especially since poor air quality can result when tightly sealed homes lack adequate ventilation. These filters serve as your first line of defense against airborne indoor pollutants such as dust, pollen, pet dander, mold spores, and even fine particulate matter that can worsen respiratory issues.
- Standard recommendation: Replace every 1–3 months to maintain optimal filtration
- High-efficiency filters (HEPA or MERV-13 and above): Consider upgrading for enhanced removal of smaller particles and allergens
- Bonus tip: Set a calendar reminder or use smart home alerts to never miss a change
MERV-13 rated filters are particularly effective for trapping a wide range of airborne particles in HVAC systems, helping reduce potential air quality issues and supporting overall respiratory health. Regular replacement also ensures your system runs efficiently, preventing strain and prolonging its lifespan.
2. Keep Your Home Clean
Dust, dirt, and pet hair accumulate in carpets, upholstery, and other surfaces, significantly contributing to indoor air pollution. This is particularly important in older homes in Rochester, which may contain legacy allergens and contaminants from past materials and activities. A consistent cleaning routine helps control these indoor sources before they become airborne and impact your health.
- Vacuum at least once a week using a HEPA filter vacuum to capture fine particles effectively
- Dust surfaces with a damp cloth or use damp cleaning methods to prevent dust from becoming airborne
- Regularly wash bedding, curtains, and upholstery to reduce allergens like dust mites and pet dander
By maintaining cleanliness, you reduce indoor pollutants and support better respiratory health for everyone in your home.
3. Let Fresh Air In
Proper ventilation is crucial for flushing out stale indoor air and diluting indoor pollutants. Bringing in fresh outdoor air helps reduce the buildup of carbon dioxide and other harmful contaminants, improving overall indoor air quality and comfort. On days with mild weather and good outdoor air quality, open windows or doors briefly to ventilate your home. Use exhaust fans in kitchens and bathrooms to remove trapped pollutants and excess moisture, which can contribute to mold growth.
However, during periods of outdoor air pollution or extreme weather, limit ventilation to prevent introducing outdoor pollutants inside. Consider using demand-controlled ventilation systems that adjust airflow based on indoor carbon dioxide levels to maintain healthy air exchange efficiently. Maintaining adequate ventilation is a key factor that contributes to better indoor air quality and supports your household’s health and well-being.
4. Control Humidity Levels
Maintaining proper humidity levels is essential for both comfort and health. High humidity above 60% can promote microbial growth, including mold, which is linked to respiratory health issues. Conversely, low humidity can irritate the skin and respiratory system. Aim to keep your home’s humidity between 30% and 50% for optimal indoor air quality.
- Use a dehumidifier in damp areas like basements or bathrooms to reduce moisture
- Run exhaust fans during cooking, showering, or other moisture-generating activities
- Consider installing a whole-home humidifier during dry winter months to maintain balanced moisture levels
Controlling humidity not only improves comfort but also helps prevent mold growth and reduces the concentration of indoor pollutants, contributing to improved health and a safer indoor environment.
5. Add Indoor Plants
Some indoor plants, such as peace lilies and snake plants, can help filter indoor air pollutants like volatile organic compounds (VOCs), contributing to healthier indoor spaces. However, it’s important to select plants thoughtfully and avoid overwatering, as excess moisture can promote mold growth in the soil. If anyone in your home has allergies or respiratory sensitivities, consider whether plants might worsen symptoms before adding them. Additionally, check if the plants are toxic to pets to ensure the safety of your furry family members. When used appropriately, indoor plants can be a natural, attractive way to support improving ventilation and enhancing indoor air quality.
6. Eliminate Chemical Pollutants
Many common household products release volatile organic compounds (VOCs), which can sometimes exceed outdoor levels by ten times. These chemicals contribute to eye, nose, and throat irritation, headaches, respiratory issues, and long-term health problems. For health reasons, reducing VOC exposure indoors is essential.
Secondhand smoke is another major indoor pollutant, containing over 7,000 harmful chemicals, including carbon monoxide and fine particulate matter. It is a major cause of respiratory diseases and lung cancer, so eliminating indoor smoking is critical to protect your family’s health.
To minimize chemical pollutants:
- Choose natural or low-VOC cleaning products and paints
- Avoid aerosol sprays, synthetic air fresheners, and harsh pesticides
- Store chemicals like paint, solvents, and pesticides safely away from living areas
- Always use proper ventilation and exhaust fans when using strong-smelling cleaners or adhesives
By reducing these sources, you help improve indoor air quality and reduce long term exposure to harmful pollutants.
7. Schedule Professional HVAC Maintenance
Even the best DIY efforts can fall short if your HVAC system isn’t properly maintained. Professional indoor air quality testing can measure total VOCs, fine particulate matter, carbon dioxide, and carbon monoxide levels. Hot water use can also release chemicals from chlorinated drinking water into indoor air, adding to VOC exposure. During a professional tune-up, your technician will:
- Inspect and clean system components
- Check ductwork for leaks and debris
- Ensure proper airflow and ventilation
- Recommend air quality products like air purifiers or humidifiers
Combustion appliances, including natural gas equipment and residential heating systems, should also be checked, since carbon monoxide can cause headaches and dizziness at 100 ppm and can be fatal at high levels. Carbon monoxide exposure can be especially risky for people with cardiovascular disease, even when levels may seem less severe to healthy adults. A health-based reference from the world health organization sets the indoor CO exposure limit at 4 mg/m3 over 24 hours. Climate change can worsen indoor air quality by increasing wildfire smoke infiltration and trapping pollution during extreme weather.
Keep Your HVAC System in Top Shape for Better Indoor Air Quality
Regular HVAC maintenance ensures your system runs efficiently and helps maintain good indoor air quality. It reduces indoor pollutants like dust, mold spores, and toxic chemicals that contribute to poor indoor air quality caused by inadequate ventilation or dirty filters. Technicians inspect for leaks, clean components, and check airflow to prevent health effects related to indoor air pollution.
Proper ventilation and airflow are key factors that contribute to better indoor air quality and support human health. Scheduling routine tune-ups also allows for testing during the indoor air quality testing process, including checking for dangerous pollutants like carbon monoxide, especially if you have combustion appliances.
