Generally, the release period of formaldehyde is as long as 5 to 15 years, and if formaldehyde is not removed in time, the health of human body is necessarily affected. At present, methods for treating formaldehyde are roughly divided into ventilation, physical adsorption and chemical treatment. The ventilation method cannot be applied under the condition that the door and the window are tightly closed; physical adsorption comprises adsorption by adopting an activated carbon bag and the like, and secondary pollution is easily caused after adsorption saturation; the chemical treatment comprises indoor treatment by using chemical agents such as photocatalyst, formaldehyde scavenger and the like, and other auxiliary equipment such as a spray gun, an air pump and the like is needed during treatment, so that the use is troublesome, and the carrying is inconvenient. The formaldehyde-removing wet tissue effectively solves the problem, and is convenient to use, carry, clean and sanitary. After formaldehyde release sources such as furniture and the like are wiped by the formaldehyde-removing wet tissue, a medicament film layer can be firmly formed on the surface of the pollution release source, and free formaldehyde in the air can be removed.
