Method 1. Ventilation method
Generally, after a new house is decorated, the windows will be opened for ventilation for a period of time. It is best to open all the windows facing the house, which can enhance air convection. In some windless times, if the formaldehyde concentration is too high, you can also use a fan to enhance convection. If you need to use an electric fan, a floor fan is more effective
Method 2. Plant absorption method
Plants have a strong ability to absorb formaldehyde, such as cacti, spider plants, reeds, iron trees, Chrysanthemums, etc. Generally, plants with large leaves and herbs absorb formaldehyde better, such as Chlorophytum, Sansevieria, etc. Formaldehyde is a harmful substance that is released over a long period of time. Placing some absorbable green plants can reduce the formaldehyde content in the room.
Method 3. Activated carbon adsorption method
Solid activated carbon has the characteristics of many pores and has a strong adsorption and decomposition effect on formaldehyde and other harmful substances. The smaller the particles of activated carbon, the better the adsorption of formaldehyde. The better the effect. Activated carbon is suitable to be placed in small spaces such as furniture, and combined with Qingmanlvyou nano photocatalyst to remove formaldehyde. If sprayed irregularly for a week, the formaldehyde can be reduced to 0.02. It can play a key role in adsorbing and decomposing formaldehyde.
However, after being used for a period of time, activated carbon will be saturated, so it must be exposed to the sun and then reused, otherwise the activated carbon will lose its adsorption effect.
Method 4. Put water indoors
Another simple method is to put a basin of water indoors. Because formaldehyde is soluble in water, putting a basin of water can allow the water to To absorb part of the formaldehyde, if possible, you can also put some vinegar and salt in the water.
