We spend approximately 90% of our time indoors. However, reports from the World Health Organization (WHO) indicate that indoor air pollution levels are often 2 to 5 times higher than outdoor levels. These invisible molecules, particulate matter, and gases silently affect our sleep quality, productivity, and long-term health.

Relying on your "sense of smell" to judge air quality is insufficient. To truly take control of your indoor environment, you need to monitor these 10 key air quality metrics.

1.PM2.5 (Fine Particulate Matter)

The most well-known pollutant. PM2.5 particles are small enough to reach deep into the lungs and enter the bloodstream. Long-term exposure is linked to respiratory inflammation and heart disease.

2.PM10 (Inhalable Particulate Matter)

This includes dust, pollen, and mold spores. While larger than PM2.5, they can irritate the eyes, nose, and throat.

3.PM1.0 (Ultrafine Particles)

An "invisible killer" even more dangerous than PM2.5. Often originating from second-hand smoke or cooking fumes, these particles can easily penetrate biological barriers.

4.HCHO (Formaldehyde)

The primary threat in newly renovated homes. Formaldehyde often leaks from engineered wood, adhesives, and paints. Its release cycle can last anywhere from 3 to 15 years.

Note: Formaldehyde can exceed safe limits even when no odor is present.

A mix of hundreds of gases like benzene and toluene found in cleaners, perfumes, and carpets. They are a leading cause of "Sick Building Syndrome."

While not a toxic gas itself, high indoor CO2 levels (above 1000 , text{ppm}) cause dizziness, drowsiness, and reduced cognitive function. It is the best indicator of proper ventilation.

Indoor temperature affects both comfort and the release rate of toxins. For every 1^circtext{C} increase, formaldehyde release can jump by 15%-30%.

High humidity (> 60%) promotes mold and dust mites; low humidity (< 30%) causes dry skin and irritated respiratory membranes. Aim for 40%-50%.

A comprehensive index that simplifies complex pollutant data into a single, intuitive score, allowing you to see at a glance if your environment is "Safe" or "Hazardous."

Capturing subtle changes—like those caused by cooking or spraying hairspray—requires high-performance laser and electrochemical sensors. Reliability is the foundation of any monitoring strategy.

Many basic detectors only measure PM2.5 or temperature. However, air pollution is complex. For example, your PM2.5 might be low, but high CO2 levels from poor ventilation could still be killing your productivity.

With our [10-in-1 Multi-Gas Air Quality Tester], you can:

*Full Coverage: Master all 10 core parameters simultaneously.

*High-Precision Alerts: Utilize NDIR (Non-Dispersive Infrared) sensors for professional-grade CO2 accuracy.

*Visualized Data: View everything on a 4.3-inch large color LCD screen.

*Smart Automation: Use the relay signal outputs to automatically trigger fans or humidifiers when thresholds are met.
