1. Plants can remove formaldehyde. Although they can remove formaldehyde, the amount of formaldehyde they absorb is very limited, and when the indoor concentration is high, if only plants absorb formaldehyde, the amount is very large.
3. 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.
5. The release speed of formaldehyde mainly depends on two factors, one is temperature and the other is humidity, so we can use this characteristic of formaldehyde to keep the room in a high temperature and humidity state by using heaters and humidifiers, and then absorb the formaldehyde that has been released at home with ventilation or adsorption materials. This method is mainly to control formaldehyde lurking at home, and the effect is very good?
6. The fresh air system is a system that filters the outdoor air, transports it to the room through pipes, and discharges the harmful substances contained in the room from the corresponding pipes. When in use, it can continuously send filtered fresh air into the room to achieve the purpose of purifying the air.
