The Problem: Formaldehyde in Your Home That You Cannot Smell, See, or Detect Without Help
Formaldehyde (HCHO) is one of the most common and most harmful indoor air pollutants — and one of the least understood. It off-gasses from new furniture, flooring, cabinetry, insulation, and building materials for months or years after installation. It is present in many cleaning products, personal care products, and textiles. At low concentrations, it causes eye, nose, and throat irritation. At higher concentrations, it is a known human carcinogen linked to respiratory disease and increased cancer risk.
The problem is that formaldehyde is colourless and has a detectable smell only at concentrations significantly above the safe threshold — meaning that by the time you can smell it, you have already been exposed to harmful levels for some time. Without a monitor, there is no way to know whether the air in a newly furnished room, a recently renovated space, or a poorly ventilated home contains dangerous levels of HCHO.
The 5-in-1 CO2 Air Quality Monitor adds HCHO detection to a comprehensive suite of air quality measurements — CO2, TVOC, temperature, and humidity — giving you real-time visibility into five of the most important parameters affecting your indoor air quality simultaneously.
Five Parameters, One Device: The Complete Indoor Air Quality Picture
CO2 monitoring reveals ventilation adequacy — the foundational parameter that affects all other indoor air quality measurements. HCHO detection identifies formaldehyde off-gassing from furniture and building materials. TVOC monitoring captures the cumulative chemical burden from everyday products. Temperature and humidity monitoring ensures the physical conditions in your space support health and comfort. Together, these five measurements provide a comprehensive, real-time picture of your indoor environment that no single-parameter monitor can match.
1-Second Real-Time Updates: Immediate, Actionable Data
The 1-second update rate is the feature that makes this monitor genuinely useful rather than simply informative. You can see in real time how opening a window affects CO2 levels, how new furniture affects HCHO, how cooking affects TVOC. This immediate feedback loop empowers you to take action and verify that your interventions are working — transforming the monitor from a passive measurement device into an active tool for improving your indoor environment.
Long Battery Life: Continuous Monitoring Without Interruption
The 1200mAh battery provides 240–360 minutes of continuous monitoring on a single charge — enough for a full working day of office monitoring, an extended home session, or a long car journey. The USB-C charging means you can top up from any standard charger, power bank, or laptop port.
