FAQs

Please read our FAQs page to find out more.

What does the KyoAir SENTRY actually measure?

The KyoAir SENTRY monitors 15 environmental parameters simultaneously: CO₂, carbon monoxide, formaldehyde, total VOCs, PM0.3, PM1.0, PM2.5, PM10, real-time AQI, temperature, and humidity. All of it displayed continuously on a single smart screen. Most monitors track two or three parameters. The KyoAir SENTRY tracks the full picture.

Why does the KyoAir SENTRY track PM0.3 and not just PM2.5?

PM2.5 is the standard most monitors stop at. But PM0.3 particles are significantly smaller, penetrate deeper into the lungs, and carry a higher health risk. The KyoAir SENTRY detects PM0.3, PM1.0, PM2.5, and PM10, giving you a complete picture of particulate pollution that a standard AQI monitor simply cannot provide.

Can the KyoAir SENTRY detect formaldehyde and carbon monoxide?

Yes. The KyoAir SENTRY includes high-precision sensors for both formaldehyde and carbon monoxide, two of the most dangerous indoor pollutants precisely because they are completely invisible and odourless. Formaldehyde off-gasses from new furniture and paint for months. Carbon monoxide can be life-threatening at elevated concentrations. The KyoAir SENTRY detects both in real time.

Does the KyoAir SENTRY work with KyoAir air purifiers?

Yes, and this is where it becomes most powerful. The KyoAir SENTRY monitors your air continuously and tells you exactly when purification is needed, which pollutant is elevated, and whether your KyoAir purifier has brought levels back to safe. It turns reactive purification into an informed, data-driven system.

Is the KyoAir SENTRY only an air quality monitor?

No. The KyoAir SENTRY also functions as a smart desk device with a date and time display, alarm clock, and countdown timer. It is designed to sit permanently in any room, providing continuous air quality awareness alongside everyday utility, so it is always on, always visible, and always working.
