Hangzhou is a beautiful city and a city with rapid economic development. With the acceleration of urbanization and the increase of population, formaldehyde pollution has gradually become a serious environmental problem. Here are some ways to control formaldehyde in Hangzhou:

1. ventilation: keeping indoor ventilation is the most basic in in addition to formaldehyde law. Opening windows, doors and other vents to exchange indoor air with outside air can effectively reduce the concentration of formaldehyde.

2. Plant purification: Some plants, such as chlorophytum, aloe and Eupatorium adenophorum, can absorb harmful substances such as formaldehyde in the air and purify the air. Some of these plants can be kept indoors.

3. Carbon coating adsorption: activated carbon, bamboo charcoal and other materials can adsorb harmful substances such as formaldehyde in the air and play a role in purifying the air. You can put these materials indoors, or use a special air purifier to filter formaldehyde in the air.

4. Photocatalyst purification: Photocatalyst can decompose harmful substances in the air, including formaldehyde, through the action of ultraviolet rays. A special photocatalyst air purifier can be used to purify indoor air.

It should be noted that although the above methods can reduce the indoor formaldehyde content, they cannot completely remove formaldehyde. If the indoor formaldehyde content is too high, it is recommended not to stay for the time being, and then stay after the formaldehyde is released. At the same time, in the decoration process, we should also choose low-formaldehyde environmental protection materials to minimize the generation of formaldehyde.
