Why does formaldehyde exceed the standard?


Some time ago, Mandy’s newly renovated new house was tested for indoor air. The results showed that the concentration of formaldehyde in both the master bedroom and the second bedroom exceeded 0.20, and the formaldehyde exceeded the standard twice.

The decoration of our home is done by hand, all the materials that need to be used are very careful, and all the indicators meet the requirements; all the furniture is also the most expensive and best on the market, and they are also the most environmentally friendly materials, but when indoor air testing, why Will formaldehyde still exceed the standard?

Mandy expressed his doubts.

In fact, this is not an isolated phenomenon. The main materials used in decoration and the furniture purchased by many people have obtained the green environmental protection label, but the formaldehyde concentration is still more than 0.10 mg/m3 when checked at the time of check-in.


01. What is the current environmental protection standard for decoration materials?

We first need to understand that when purchasing decoration materials and new furniture, some businesses will promise to say that it is zero formaldehyde. But in fact, no formaldehyde-free furniture and decoration materials currently exist, so don't be misled.

According to European environmental protection standards, wood products are divided into three levels according to the amount of formaldehyde released, namely

E0 level-formaldehyde emission ≤0.5mg/L

E1 level-formaldehyde emission 0.5mg/I~1.5mg/L

Level E2-Formaldehyde emission is greater than 1.5mg/L

Only wood products that have obtained E1 certification can be used for interior decoration. They are known as green building materials and have less harm to the human body. E0 board is currently the highest environmental protection standard man-made board, suitable for children, pregnant women, etc. Room decoration for low crowds.

02. What is the difference between finished furniture and test samples?

The biggest difference between the two is the difference in area.

The actual material area of the finished furniture is much higher than the area of the test sample.

To give a simple example, a bedside table requires a board area of 1.5 square meters; to make a table requires a board of more than 3 square meters, and a bedroom cabinet requires a board of more than 10 square meters; but the samples taken for testing are only capable of A small amount of real objects representing the quality of this product.

The difference in area between the two is tens or even hundreds of times. The results of testing based on this standard sometimes cannot objectively reflect the overall release of harmful substances in a small space of those furniture products.

Moreover, the finished furniture will inevitably use adhesives, paints and other materials during its processing. The harmful substances released are not only formaldehyde, but also benzene, toluene, xylene and other harmful substances.

Consumers smell a lot of odors in homes, which are often produced by these harmful substances, which can also endanger the health and safety of consumers.

03. Attention! Formaldehyde will also stack!

Have you neglected that indoor air pollution will also be superimposed?

Even if all the furniture products you buy meet the standards, it will cause formaldehyde to exceed the standards.

Because you can’t have only one piece of furniture in your home. In addition to sofas, there will also be wardrobes, dressing tables, dining tables and chairs, bedside tables, beds, cloakrooms, etc.

All these furniture are put together and release formaldehyde at the same time. It's hard to avoid.

This is why you are buying environmentally friendly materials, and the formaldehyde still exceeds the standard.

Not to mention that some decoration companies secretly use some unqualified materials during the decoration process, so that the formaldehyde content in the home is even greater.

04. How to remove formaldehyde safely and effectively?

Formaldehyde is not only harmful but also has a particularly long incubation period. Generally speaking, the volatilization period of new house decoration is as long as 3 to 15 years, which is an invisible health killer.

In order to solve some harmful odors left by the decoration, many people adopt some "earth methods" such as putting onions and vinegar to absorb harmful gases in the room. In fact, they are just covering the ears and the bells. They only cover the smell and cannot drive away the formaldehyde.

However, the use of plant absorption and carbon-coated adsorption are relatively limited. The symptoms are not the root cause, and the results are only short-term.

So how can we effectively solve the formaldehyde problem?

BackNature appeals to everyone, for the sake of your health and your family's health, you must pay enough attention to indoor decoration pollution, so that your family members should not be harmed. In addition, after the new house has just been renovated, don't worry about moving in. It is recommended to ask a professional organization to conduct a comprehensive inspection of the indoor air quality to ensure that the quality is up to the standard before moving in!
