If you find a formal formaldehyde testing company, it will be more expensive, a few hundred yuan or 1000 yuan. If it is detected that the indoor formaldehyde content exceeds the standard, indoor formaldehyde should be removed as soon as possible. There are many methods in in addition to formaldehyde. Let's share with you the practical in addition to formaldehyde method at home.

First, Ruishi

It can actively adsorb indoor free formaldehyde, and the process will not be affected by any external factors such as temperature, humidity and illumination. The adsorption rate of formaldehyde is also dozens of times that of ordinary adsorption materials. In addition, its unique decomposition function can decompose the adsorbed formaldehyde into harmless carbon dioxide and water, and then discharge it, so that its internal pores are always in an unsaturated state, and the formaldehyde removal rate can reach over 90%. It should be noted that it is a gray ore with irregular shape, not round particles?

Second, activated carbon

Activated carbon has the function of adsorbing harmful substances such as formaldehyde, but it has no decomposition function, so its adsorption capacity is limited and it is easy to saturate, so it needs to be replaced frequently, otherwise it will become a new pollution source, releasing harmful substances and causing secondary indoor pollution.

Third, open the window for ventilation

This is a gift from nature and the most economical and practical in addition to formaldehyde method. As long as the window is opened, fresh air will enter the room, diluting and purifying formaldehyde.

Fourth, fresh air system.

The principle of fresh air system is ventilation. The outdoor fresh air is filtered and transported indoors, and then harmful substances such as formaldehyde are discharged outdoors to achieve the effect of in addition to formaldehyde.

Five, formaldehyde scavenger

There are many principles of formaldehyde scavenger, including decomposing formaldehyde and blocking formaldehyde. The former only decomposes free formaldehyde, and the bound formaldehyde in the material is still being decomposed and released. The latter uses a protective film to isolate formaldehyde from the air, and formaldehyde still exists. When the protective film is broken, formaldehyde will still gush out in large quantities!

Formaldehyde in indoor decoration pollution mainly comes from indoor decoration materials, among which latex paint, paint, wallpaper and other wall coatings are the main harmful substances, so it is very important to control formaldehyde from the source.
