Is there any simple way to detect whether there is formaldehyde in furniture, and how to identify the standard?

The simplest way to detect formaldehyde at home is to use formaldehyde test box, but the detection may be affected by temperature, humidity and space size. In order to accurately detect the indoor formaldehyde content, it is suggested to prepare more test boxes and calculate the average value. After introducing how to measure indoor formaldehyde concentration, some efficient in addition to formaldehyde methods are brought to you.

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 an irregular gray ore, not a round particle.

Second, the fan

The fan can play the role of "inducing wind" and accelerate the exhaust of indoor gas containing free formaldehyde. This method is only useful for houses with poor ventilation, but not for houses with good ventilation effect.

Three. 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.

Four, 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 gush out in large quantities?

Verb (abbreviation of verb) 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.

Most of us are office workers and our time is very limited. Therefore, it is best to remove formaldehyde from the air by multiple methods at the same time.
