In recent years, more and more people are aware of the importance of living environment health and environmental protection, and search professional testing and governance institutions or companies through the Internet, and find that many companies are using the slogan of "zero formaldehyde" to attract customers' attention. Then, as these companies say, can the family achieve "zero formaldehyde" after governance?

Before giving the answer, we must first understand different people's understanding of "zero formaldehyde": in the eyes of most ordinary people, zero formaldehyde means that furniture, building materials and air do not contain any formaldehyde, and "zero formaldehyde" means no formaldehyde. Furniture and building materials manufacturers believe that "zero formaldehyde" can have many different standards, and its essence means that more or less formaldehyde must be brought; In the eyes of professional formaldehyde detection and treatment institutions or companies, whether before or after treatment, the term "zero formaldehyde" is unscientific, and it is almost impossible to achieve "zero formaldehyde". At best, it can only be said to be close to zero formaldehyde.

Then, why are there so many professional in addition to formaldehyde companies holding the slogan of "zero formaldehyde" when they know it is impossible?

Reason one: stealing the concept-the national standard is equal to "zero formaldehyde"

Some say that reaching the national standard means "zero formaldehyde", some say that reaching the European standard means "zero formaldehyde", some say that reaching the Japanese standard means "zero formaldehyde", and some say that the formaldehyde content of their furniture tends to zero, but the real "zero formaldehyde" means no formaldehyde content. So it is "zero formaldehyde". As for the specific data, I can't say.

Reason 2: crossing the sea-tasteless is "zero formaldehyde"

As we all know, formaldehyde is a colorless and odorless substance. At present, when most people judge the effect before and after treatment, the only verification method is to smell it and think that "no smell should mean no formaldehyde".

Many companies in "in addition to formaldehyde" just grasped this point, and when they talked about "zero formaldehyde", they showed a kind of self-confidence and told consumers that "empty words have no evidence, you can smell them". I don't know how many times you have encountered this kind of scene, and the final result is either tasteless or delicious. It is precisely because consumers have all kinds of misunderstandings in cognition that many companies can take advantage of it.

You can't tell whether it contains formaldehyde by smell. Just because the smell is gone and the light is gone doesn't mean that the formaldehyde disappears.

In fact, we don't have to say that aldehyde changes color. Formaldehyde is not as terrible as imagined. As long as the formaldehyde emission at home meets the national air quality standards, it is harmless to the human body. For example, in our daily food, beer contains a small amount of formaldehyde (the formaldehyde content is 2mg/L), and fruit also contains a certain amount of formaldehyde. In addition, the content and release of formaldehyde are not the same concept. If furniture and building materials contain formaldehyde, but the release amount is small, it will not affect the human body; If the base material used is well sealed, the formaldehyde emission of some wood-based panels is even smaller than that of natural wood.
