Breathe Easier — Know What's in Your Air
The Shunmaii 5-in-1 Indoor Air Quality Monitor gives you a real-time snapshot of your home or office environment in a single compact device. Simultaneously track CO₂ levels, formaldehyde (HCHO), total volatile organic compounds (TVOC), temperature, and humidity — all on a crisp 2.8-inch TFT-LCD display. With color-coded CO₂ alerts and up to 30 hours of battery life per charge, staying on top of your indoor air quality has never been easier.
Made in Mainland China.
Why Indoor Air Quality Matters
Poor indoor air quality can cause fatigue, headaches, difficulty concentrating, and long-term health issues. Studies from the U.S. Environmental Protection Agency (EPA) on Indoor Air Quality show that indoor air can be 2–5× more polluted than outdoor air. This monitor empowers you to act — open a window, run an air purifier, or identify hidden sources of pollutants — before problems escalate.
Key Features
- 5-in-1 Detection: Measures CO₂ (400–5,000 ppm), HCHO (0–1.999 mg/m³), TVOC (0–9.99 mg/m³), temperature (0–50°C), and humidity (0–99% RH) simultaneously.
- Color-Coded CO₂ Alerts: Instant visual feedback — green (0–799 ppm), yellow (800–1,199 ppm), orange (1,200–1,599 ppm), and red (1,600+ ppm) — so you know at a glance when to ventilate.
- High-Sensitivity Semiconductor Sensor: Fast <1-second response time with an electrochemical module for stable, low-interference readings.
- Large 2.8" TFT-LCD Display: 240×240 glass screen clearly shows all metrics plus battery level in one view.
- No Calibration Needed: Simply power on and start measuring — zero setup hassle.
- Long Battery Life: Built-in 1,200 mAh lithium battery provides up to 30 hours of continuous use; recharges fully in ~2–3 hours via USB Type-C.
- Wi-Fi Connected: Supports Wi-Fi connectivity for smart home integration and remote monitoring.
- Compact & Portable: Slim 90 × 70 × 35 mm ABS body goes anywhere — bedroom, nursery, office, workshop, or classroom.
- Enhanced Ventilation Design: Multiple vents promote airflow around the sensors for faster, more accurate readings.

⚠️ Note: This device uses a semiconductor sensor that provides qualitative (indicative) readings rather than laboratory-grade quantitative precision. It detects mixed CO₂ such as exhaled breath — it is not designed to measure pure CO₂ gas. Minor color variation and ±1–2 cm measurement differences may occur.

Frequently Asked Questions
Q: What does this 5-in-1 air quality monitor actually measure?
A: It simultaneously measures five key air quality parameters: CO₂ concentration (400–5,000 ppm), formaldehyde (HCHO, 0–1.999 mg/m³), total volatile organic compounds (TVOC, 0–9.99 mg/m³), ambient temperature (0–50°C), and relative humidity (0–99% RH). All readings appear on the 2.8-inch color display in real time.
Q: Is this monitor accurate enough for home use?
A: Yes — for everyday home and office monitoring it performs very well. It uses a high-sensitivity semiconductor sensor with a CO₂ accuracy of ±150 ppm and a <1-second response time. Keep in mind it provides indicative (qualitative) readings rather than laboratory-grade precision, and it detects mixed CO₂ (e.g., from human breath) rather than pure CO₂.
Q: Do I need to calibrate the device before use?
A: No calibration is required. Simply charge the device fully, power it on, and it will begin measuring your indoor air quality immediately. This makes it ideal for non-technical users who want plug-and-play simplicity.
Q: How long does the battery last and how do I charge it?
A: The built-in 1,200 mAh lithium battery provides up to 30 hours of continuous use on a full charge. It recharges via the included USB Type-C cable (5V/1A adapter) in approximately 2–3 hours.
Q: Can I use this monitor in an office or classroom?
A: Absolutely. High CO₂ levels in enclosed spaces like offices and classrooms are a leading cause of drowsiness and reduced concentration. This monitor's color-coded alerts make it easy to know when to open a window or improve ventilation — helping keep everyone alert and comfortable.
