1. Window ventilation is a zero-cost method for indoor in addition to formaldehyde, and it is also a practical method. However, the ventilation mode also has many limitations, which have a certain relationship with the type and location of the house, and the formaldehyde in the decoration materials is released for a long time. It is too slow to control indoor formaldehyde only by window ventilation, and ventilation can only be used as an auxiliary method to control formaldehyde.
4. Choose plants that can adsorb formaldehyde. Plants such as green radish, aloe and chlorophytum can adsorb some formaldehyde pollution, and can also be in addition to formaldehyde. Putting some green plants in the new house can also beautify the room and purify the air. However, the adsorption capacity of plants is limited. If the concentration of formaldehyde is too high, plants will wither and die.
5. The air purifier has a good filtering effect on odor and indoor pollutants, and can achieve the purification effect quickly, but it needs to be turned on continuously for 24 hours, and the purification range of each machine is limited, so it needs to be configured in each room, so the use cost will be higher. If it is used in the whole house, it will be a bit high, so families with sufficient budget can try it.
6. At present, most of the photocatalysts that people often mention are titanium dioxide. Formaldehyde can be decomposed into carbon dioxide and water by ultraviolet radiation, but its work needs the participation of light and ultraviolet radiation, which has certain limitations in in addition to formaldehyde?
