How about a new house in Guangzhou, in addition to formaldehyde?

Under normal circumstances, after the renovation of new houses, windows will be opened for ventilation for a period of time. It's best to open all the windows facing the house, so as to strengthen air convection. In some cases where there is no wind and little wind, if the formaldehyde concentration is too high, you can also use an electric fan to strengthen convection. If you need to use an electric fan, the floor fan is better.

Method two. Plant absorption method

Plants have a strong ability to absorb formaldehyde, such as cactus, chlorophytum, reed, cycad, chrysanthemum and so on. Generally, plants and herbs with large leaves absorb formaldehyde better, such as chlorophytum, Eupatorium adenophorum and so on. Formaldehyde is a long-term release of harmful substances, and placing some absorbable green plants can reduce the indoor formaldehyde content.

Method three. active carbon adsorption

Solid activated carbon has the characteristics of many pores and has strong adsorption and decomposition effects on harmful substances such as formaldehyde. The smaller the activated carbon particles, the better the adsorption effect of formaldehyde. Activated carbon is suitable to be placed in small spaces such as furniture, and can be removed by Man Qing Lv You nano photocatalyst, and formaldehyde can be reduced to 0.02 if sprayed irregularly for one week. It can play a key role in the adsorption and decomposition of formaldehyde.

However, after a period of use, the activated carbon will be saturated, so it must be exposed to the sun before use, otherwise the activated carbon will lose its adsorption.

Method four. indoor drainage

Another simple way is to put a pot of water indoors, because formaldehyde is soluble in water, so putting a pot of water can make the water absorb some formaldehyde, and if possible, put some vinegar and salt in the water.
