Understanding Your Results
Your indoor air quality is a crucial factor for your health, comfort, and productivity. This tool focuses on two key metrics: Carbon Dioxide (CO₂) and Relative Humidity.
Carbon Dioxide (CO₂)
CO₂ is a gas that you exhale with every breath. While not typically toxic at indoor levels, high concentrations indicate poor ventilation. This can lead to feelings of stuffiness, fatigue, headaches, and reduced cognitive function. Outdoor CO₂ levels are typically around 400 ppm (parts per million).
- < 800 ppm: Excellent. Indicates good, fresh air exchange.
- 800 - 1000 ppm: Fair. Acceptable for most people, but ventilation could be improved.
- 1000 - 1500 ppm: Poor. Complaints of drowsiness and poor air are common.
- > 1500 ppm: Very Poor. Can lead to significant cognitive impairment and health complaints.
Relative Humidity
Relative humidity is the amount of moisture in the air compared to what the air can hold at that temperature. It affects comfort, health, and even the longevity of your home.
- 40-60%: Ideal. This range is most comfortable and minimizes the growth of mold, bacteria, and viruses.
- 30-40%: Dry. May cause dry skin, irritated sinuses, and static electricity.
- > 60%: Humid. Can lead to condensation, mold growth, and a stuffy feeling.
Tips for Better Air Quality
Improving your indoor air is often straightforward. Here are some effective strategies:
- Ventilate Regularly: Open windows and doors for a few minutes each day to bring in fresh air, especially in bedrooms and living areas.
- Use Exhaust Fans: Run exhaust fans in your kitchen when cooking and in your bathroom when showering to remove moisture and pollutants.
- Control Humidity: Use a dehumidifier if your home is too humid or a humidifier if it's too dry.
- Introduce Houseplants: Certain plants like snake plants, spider plants, and peace lilies can help filter indoor air.
- Clean Regularly: Dusting, vacuuming with a HEPA filter, and washing bedding frequently can reduce indoor allergens and pollutants.
- Check Your HVAC System: Ensure your heating, ventilation, and air conditioning (HVAC) system is clean and has a high-quality filter that is changed regularly.

This tool provides a general assessment of indoor air quality based on CO₂ and humidity. It is for educational purposes and is not a substitute for a professional assessment. Other factors like VOCs, particulate matter (PM2.5), and allergens also significantly impact air quality.
