First, the onion in addition to formaldehyde way is not desirable. Onions only mask the smell of formaldehyde, but can't remove it.
Second, grapefruit peel can't play the role of in addition to formaldehyde. Many books about earthwork methods in in addition to formaldehyde will recommend you to use in addition to formaldehyde with pomelo peel and orange peel. This indigenous method is indeed used, but it is not based on this method. It is useful.
Third, activated carbon activated carbon has always been the main means of in addition to formaldehyde. This method is scientific and effective. Activated carbon, activated carbon and other substances have developed pore structure and specific surface area, which can adsorb formaldehyde into their own gaps. Activated carbon is only adsorbed, so it is easily saturated, and it is decomposed while being adsorbed. It is also convenient not to bask in the sun for three years, and it does not affect our daily life.
Fourth, this is the simplest and most effective way to control formaldehyde in new houses. Long-term window ventilation is one of the most commonly used natural in addition to formaldehyde methods, but this method is easily influenced by environmental factors. The efficiency of in addition to formaldehyde is relatively low, but it is still a good auxiliary method for in addition to formaldehyde.
5. Many green plants have good adsorption capacity for formaldehyde, such as chlorophytum, Eupatorium adenophorum and green radish. We can also choose to raise some green plants at home to help control formaldehyde pollution at home, but these green plants have limited adsorption capacity for formaldehyde and can be used as an auxiliary method.
It is not difficult to keep formaldehyde in a safe range. In in addition to formaldehyde, high temperature can promote the release of formaldehyde, reduce the total formaldehyde content+physical adsorption+green planting, and many methods work together, but ventilation is essential, like traditional activated carbon, which needs to be replaced regularly, otherwise it may produce secondary pollution after saturation. Ruishi is a natural ore, not an ordinary man-made particle, and genuine products can be adsorbed at the same time.
