Formaldehyde method refers to an air purification technique that, under normal temperature conditions, decomposes formaldehyde-based pollutants into carbon dioxide and water by using a series of measures including green plant adsorption, air purification, photosynthetic oxidation, and physical ventilation, releasing them into the air in a molecular state.

At concentrations of 0.08m or higher indoors, people may experience discomfort, including red and itchy eyes, sore throat or pain, hoarseness, sneezing, chest tightness, asthma, and dermatitis.

Formaldehyde is widely recognized as a class 1 carcinogen, especially given its significance as a key industrial raw material today. Pollution is inevitable, and its volatility period is quite long, thus giving rise to the industry focused on removing formaldehyde.
