Introduction Gas stoves are convenient, but new research shows they can raise nitrogen dioxide (NO₂) levels indoors to unhealthy concentrations, affecting everyone in the home. A study from Stanford Doerr’s School of Sustainability measured NO₂ in over 100 U.S. homes, finding that pollutant levels can spike quickly and linger long after cooking. Key Findings:  Rapid and lasting exposure: Even rooms far from the kitchen can reach unsafe NO₂ levels within an hour of stove use.   Cumulative risk: Typical gas stove use puts households three-quarters of the way to the WHO annual NO₂ limit before even leaving the home.   Ventilation helps, but usage is critical: Using a range hood reduces exposure, but the most important factor is how much gas is burned.   Smaller homes are more affected: Apartments around 800 ft² can see twice the exposure of larger homes.   Environmental justice concerns: Historically marginalized households experience disproportionately higher NO₂ exposure. Conclusion: As Professor Rob Jackson emphasizes, “It’s the whole family’s problem.” With the right tools, like TELLUS monitors, households can track, understand, and improve their indoor air, creating safer, healthier living environments. How TELLUS Air Monitors Can Help: Understanding and mitigating indoor air pollution starts with accurate data. TELLUS AirU Pro monitors provide: Real-time indoor readings of NO₂ and other pollutants. Room-by-room tracking to see where exposure is highest. Actionable insights to improve ventilation and reduce risk. By monitoring indoor air quality, families can see the impact of everyday activities, like cooking, and take steps to protect their health. Air Monitors
