First, Ruishi
It is a very popular purification product in the market in recent years, mainly because it has dual functions of absorption and decomposition, and can actively absorb free formaldehyde in the air without worrying about the influence of external factors such as temperature, humidity and light. The absorbed formaldehyde will also be decomposed into water and carbon dioxide and discharged from the body without air drying and secondary pollution. It should be noted that it is an irregular gray ore, not a round particle.
Second, open the window for ventilation.
If you want to eliminate formaldehyde in the house as soon as possible, you can put a floor fan at home after the renovation, and at the same time open the window for ventilation. When the outdoor wind allows, the fan can increase the velocity of indoor and outdoor air, reduce the indoor formaldehyde content and accelerate the formaldehyde release. This may be the most effective and cheapest method.
Three. activated carbon
Using activated carbon is also a good choice. The surface of activated carbon is rich in pores, which can absorb indoor odor and play a certain role in pollution control. However, the treatment capacity of activated carbon is limited, and it will be saturated after about half a month of use, so it can't continue to work. In order to achieve the purpose of treatment, it is necessary to constantly replace new carbon packs, which invisibly increases the treatment expenditure?
Fourthly, optical contact medium.
Photocatalyst is a product that can decompose formaldehyde into carbon dioxide and water by light or ultraviolet radiation. Theoretically, one-time use can be effective for a long time, but the effect is not particularly obvious. Recommended as an auxiliary method when using.
Verb (abbreviation of verb) fresh air system
The fresh air system is similar to the method of ventilating in addition to formaldehyde, but there is no need to open a window when it is used, and the air delivered to the room is filtered. It is also used when pm2.5 exceeds the standard. The disadvantage is that the price is relatively high and it needs to be installed before renovation.
Finally, I remind you that no matter how to solve the decoration pollution problem, we must first detect the indoor decoration pollution and adopt different solutions according to different pollution levels, which will get twice the result with half the effort.
