Air Quality Tester Measures Indoor Formaldehyde Concentration

Air pollution is a major threat to human health on a global scale. According to the World Health Organisation's 2023 report, approximately 7 million people die prematurely each year from heart disease, stroke, lung cancer and respiratory diseases such as asthma and pneumonia caused by ambient air pollution. The problem is particularly acute in more economically disadvantaged countries and affects children disproportionately.

Since air itself is colourless and odourless, it is often difficult to visually identify the quality of air. This characteristic makes air pollution difficult to perceive directly and poses a considerable challenge for air quality monitoring and control. Particularly in indoor spaces, where we spend most of our daily lives, whether at home, at work or in a learning environment, long-term exposure to indoor air may have significant impacts on our health if it contains harmful components. Latent indoor pollutants such as formaldehyde and volatile organic compounds (TVOCs) can cause serious health damage without people realising it, and their effects can be far greater than we expect.

Formaldehyde is a common indoor pollutant that usually originates from interior decoration materials such as veneer sheets, synthetic flooring and wood chipboards. According to the standard, the safe indoor concentration of formaldehyde should not exceed 0.08 mg per cubic metre. Prolonged inhalation of high levels of formaldehyde may cause eye discomfort, breathing problems, allergies and, in severe cases, an increased risk of cancer.

To protect our health, it is important to monitor and improve indoor air quality. This requires the use of some advanced testing tools to find out the pollutants indoors and make sure the air we breathe is safe. Regular air quality checks can help us identify problems and take steps to reduce pollution and make our living and working environments healthier.

The air quality detector is capable of measuring indoor formaldehyde, pm2.5, PM10 and other concentrations in real time. The device has a 5-inch high-resolution capacitive touch screen, which is capable of clearly displaying multi-parameter measurement results in real time. It adopts international advanced measurement technology to ensure the high accuracy of measurement. Compact and beautiful shape design, adapt to a variety of environments, easy to carry and move. The built-in high-capacity lithium battery provides a long standby time, so that the device is not limited by power supply and site, and can be turned on and measured. The device's data refresh frequency is extremely fast, up to once per second, to ensure a sensitive response to environmental changes. Overall operation is intuitive and simple, with a full-colour, large font display that allows the user to see what is happening at a glance.
