Radon is one of the most serious indoor air quality threats — but it's not the only one. A comprehensive approach to indoor air quality protects your family from multiple hazards at once. Here's how to improve the air in your home, starting with radon and going further.
Why Indoor Air Quality Matters
The EPA estimates that indoor air can be 2 to 5 times more polluted than outdoor air. Since most people spend up to 90% of their time indoors, the quality of the air inside your home has a profound impact on long-term health.
Step 1: Test and Mitigate Radon
Radon is the most dangerous invisible indoor air pollutant. Unlike VOCs or particulates, radon causes a specific and severe health outcome — lung cancer. Addressing radon should be the first priority in any indoor air quality plan:
- Test with a continuous radon monitor for accurate long-term data.
- If levels exceed 4 pCi/L, install a professional mitigation system.
- Continue monitoring after mitigation to confirm effectiveness.
Step 2: Control Humidity and Mold
High humidity encourages mold growth, which can cause respiratory problems and allergic reactions. Keep indoor humidity between 30% and 50% using dehumidifiers and proper ventilation, especially in basements and bathrooms.
Step 3: Reduce VOCs
Volatile organic compounds (VOCs) are emitted by paints, cleaning products, furniture, and building materials. To reduce VOC exposure:
- Choose low-VOC or zero-VOC paints and finishes.
- Store chemicals in sealed containers outside the living area.
- Ventilate well when using cleaning products or adhesives.
Step 4: Improve Ventilation
Good ventilation dilutes indoor pollutants including radon, VOCs, and carbon dioxide. Consider:
- Opening windows regularly when outdoor air quality is good.
- Using exhaust fans in kitchens and bathrooms.
- Installing a heat recovery ventilator (HRV) or energy recovery ventilator (ERV) for continuous fresh air exchange without significant heat loss.
Step 5: Use Air Purifiers Wisely
HEPA air purifiers can remove particulates, allergens, and some biological contaminants. However, they do not remove radon gas — only proper ventilation and mitigation systems can address radon.
Step 6: Monitor Continuously
The best indoor air quality strategy includes ongoing monitoring. Continuous sensors for radon, CO2, humidity, and particulates give you real-time data to act on before problems become serious.
