Portable Air Quality Monitor – CO2, TVOC, HCHO, PM2.5 & PM10 with LCD & Alarm

The Air in Your Home Is Affecting Your Health — And You Have No Idea How Bad It Is

Indoor air pollution is consistently ranked among the top environmental health risks by the World Health Organisation. The air inside a typical home can be two to five times more polluted than outdoor air — containing elevated CO2 from occupants and appliances, formaldehyde (HCHO) off-gassing from furniture and flooring, fine particulate matter (PM2.5 and PM10) from cooking and cleaning, and volatile organic compounds (TVOCs) from paints, adhesives, and synthetic materials.

None of these pollutants are visible. None have a distinctive smell at the concentrations typically found indoors. And all of them can affect your health, your sleep, and your cognitive performance — without you ever knowing they're there. Until now.

The Portable Air Quality Monitor with LCD & Alarm detects five key indoor air pollutants simultaneously, displays them clearly on an LCD screen, and sounds an alarm when any parameter exceeds safe thresholds. It's the device that makes the invisible visible — and gives you the information you need to protect your family's health.

Five Parameters, One Portable Device

This monitor measures the five most common and impactful indoor air quality parameters:

• CO2 (Carbon Dioxide): Elevated CO2 from occupants and appliances causes fatigue, headaches, and poor concentration. Critical for bedrooms, home offices, and classrooms.
• TVOC (Total Volatile Organic Compounds): Off-gassing from paints, cleaning products, adhesives, and synthetic materials. Long-term exposure is linked to respiratory and neurological effects.
• HCHO (Formaldehyde): Off-gassing from furniture, flooring, and building materials. A known carcinogen at elevated concentrations, particularly common in newly furnished or renovated spaces.
• PM2.5 (Fine Particulate Matter): Microscopic particles from cooking, candles, and outdoor pollution that penetrate deep into the lungs.
• PM10 (Coarse Particulate Matter): Larger particles from dust, pollen, and cleaning activities that affect respiratory health.

LCD Display — Clear Readings at a Glance

The LCD display shows all five parameters simultaneously in a clear, easy-to-read format. No need to cycle through menus or interpret complex graphs — the current readings are always visible at a glance. The display is bright enough to read in normal room lighting and compact enough to sit on a desk, shelf, or bedside table without taking up meaningful space.

Alarm Function — Immediate Alert When It Matters

The alarm function is the feature that transforms this from a passive monitoring device into an active health protection tool. When any parameter exceeds a safe threshold, the monitor sounds an audible alarm — alerting you immediately so you can take action. Open a window. Run an air purifier. Investigate the source. The alarm gives you the information you need to respond before the problem becomes a health risk.

Portable — Monitor Any Room, Any Time

The portable design means you can move this monitor between rooms to identify where air quality problems are most severe. Check the bedroom overnight. Monitor the kitchen during cooking. Test the home office during a long work session. The portable format gives you flexibility that fixed wall-mounted monitors cannot provide.
