Accurate, portable air quality monitoring for healthier indoor environments Key benefits Understand five critical air metrics at a glance: CO2, particulate matter (PM), temperature, total volatile organic compounds (TVOC), and formaldehyde (HCHO). Make targeted decisions about ventilation, filtration, and occupant safety. Real-time readings on an easy-to-read screen let you respond immediately to poor conditions instead of guessing or waiting for symptoms. Battery-powered portability lets you check air quality anywhere—home, office, or while traveling—without needing a power outlet. High-sensitivity, advanced sensors deliver reliable data you can trust for everyday use or when evaluating a new space. What it does and why it matters CO2: Reveals ventilation levels so you can improve airflow in occupied rooms. Particulate matter (PM): Detects fine particles that affect respiratory health and the performance of air purifiers. Temperature: Provides context for comfort and HVAC performance. TVOC: Alerts you to common indoor chemical pollutants from paints, cleaning agents, or off-gassing furniture. Formaldehyde (HCHO): Identifies a common indoor toxin produced by some building materials and furnishings. Practical features Real-time data display: Instant, easy-to-read updates on current conditions. Battery-operated: Use it anywhere—no cords required. Ideal for quick spot checks and mobile monitoring. High sensitivity and accuracy: Advanced sensing technology for dependable readings that support sound decisions about indoor air management. Compact, portable design: Easy to move between rooms or pack for trips. Use scenarios At home: Check nursery or bedroom air to ensure safe sleep environments and decide when to ventilate or run a purifier. In the workplace: Monitor conference rooms and open-plan offices to confirm ventilation is keeping CO2 and particulates at healthy levels during meetings. While traveling or moving into a new space: Test hotel rooms, rental properties, or recently renovated rooms for TVOC and formaldehyde before extended stays. How to use it Place the monitor in the occupied area at breathing level, view the screen for real-time values, and take action (open windows, adjust HVAC, use purifiers) when readings indicate poor air quality. Trusted, practical monitoring to help you identify problems and take clear, immediate steps to improve indoor air health.
