Indoor Air Quality Month Reminder: It’s Time to Create a Healthier, Cleaner Living Space

People tend to assume that air pollution just occurs outdoors. But the Environmental Protection Agency (EPA) has found that indoor air can be two to five times more polluted than outside air. Since most people spend nearly 90% of their time indoors, poor indoor air quality in your home or workplace can have a direct impact on your health. During October – National Indoor Air Quality (IAQ) Awareness Month – focus on the how you can significantly improve your indoor air quality, thus creating a healthier living space for your family and colleagues.

Take Note of Hidden Dangers
VOCs (volatile organic compounds) and mold account for 80% of poor indoor air quality. VOCs come from everyday items like paints, carpets, cleaning products, and furniture. Mold thrives in damp, poorly ventilated areas. Both can silently affect your respiratory health.
Other pollutants, like dust, pet dander, radon, asbestos, smoke, and formaldehyde also contribute to poor indoor air quality. When these toxins accumulate indoors, they can trigger a variety of health issues.

Pay Attention to the Symptoms Caused by Poor IAQ
If you’ve been experiencing unexplained health issues, your indoor air may be the culprit. Common symptoms include:
- Asthma flare-ups
- Cold or allergy-like symptoms
- Persistent coughing
- Fatigue and headaches
- Eye, nose, and throat irritation
- Nausea and dizziness
- Irritability
Long-term exposure to poor indoor air quality can lead to more serious conditions, including heart disease and respiratory illnesses.

Take Steps to Improve Indoor Air Quality
You can take several simple yet effective steps to improve the air quality in your home or workplace:
- Test for Mold and VOCs: Testing is the first step toward better indoor air quality. While DIY testing kits may sometimes seem faster, less expensive or more convenient, their shortcomings far outweigh their benefits. Relying on these kits for accurate and reliable information about mold can lead to misleading results, uninformed decisions, and health risks. RTK Environmental offers professional IAQ assessments that can reveal hidden mold and measure VOC levels in your home.
- Control Moisture: Since mold spores multiply in damp or wet situations, keep indoor humidity levels between 30-50% to prevent mold growth. Measure humidity in your home with a hygrometer or the “ice cube” method where you place a few ice cubes in a glass of water, wait four minutes, and check for condensation on the outside of glass. Fix leaks quickly and ensure good ventilation in bathrooms and kitchens to reduce moisture buildup.
- Ventilate Your Home: Open windows regularly to allow fresh air in, especially on days when outdoor pollution levels are low.
- Use Air Purifiers: HEPA air purifiers with carbon filters can help reduce mold spores, VOCs, and other pollutants.
- Choose low-VOC products such as water-based paints and non-toxic cleaners vegetable-based surfactants and solvents: Opt for low-VOC or VOC-free products when purchasing paint, furniture, or cleaning supplies to reduce your exposure to harmful chemicals.
- Maintain Your HVAC System: Regularly service your HVAC system to ensure it filters and circulates air effectively.

Take Action: Test Your Indoor Air Today
Improving your indoor air quality is a year-round commitment, but it starts with identifying what is causing the problem. Regular testing can reveal harmful pollutants like VOCs and mold that might be affecting your health. RTK Environmental provides comprehensive IAQ assessments to help you understand and address specific issues in your home or workplace.
