1. Ventilation equipment
Window ventilation can quickly discharge free formaldehyde outside. As long as the local air quality reaches the standard, other pollutants will not be introduced, and it is convenient to use and low in cost. However, it needs to be adhered to for a long time, because formaldehyde is released for a long time and poor ventilation is prone to repeated situations.
2. Activated carbon
Activated carbon is a traditional physical adsorption material, which is well received in indoor and outdoor pollution control. It has large specific surface area and strong adsorption capacity, but its adsorption capacity is limited and it does not have decomposition function. It needs to be replaced regularly when it is used, otherwise it may produce secondary pollution when it is saturated.
plant
Using green plants to purify formaldehyde is a popular and promising in addition to formaldehyde method. Plants will absorb a part of formaldehyde during photosynthesis, but the absorption amount is very small, so it is suggested to use it as an auxiliary method in in addition to formaldehyde.
5. Air purifier
Air purifiers used to be high-end products. Qian Yan, who used to be Wang Xietang, now flies into the homes of ordinary people. Although it is not small, the ability of air purifier without in addition to formaldehyde function to purify formaldehyde can be ignored. Products with formaldehyde adsorption function also need to be opened for a long time, and in addition to formaldehyde filter boxes need to be replaced regularly to ensure the in addition to formaldehyde effect.
6. High temperature
High temperature and drying will accelerate the volatilization of harmful substances such as formaldehyde, so drawers, movable furniture, mattresses and so on. What can be taken out can be taken to the balcony for ventilation. In addition, furniture and homes that can't be dried can be fumigated at high temperature, and hanging machines, steam engine mops and high-temperature steam can accelerate the volatilization of formaldehyde.
