After Mr. Lin's new house was ventilated and dried for more than half a year, the couple moved into the new house with their 4-year-old daughter. Only one month after moving into the new house, Mr. Lin's daughter suddenly developed symptoms such as persistent high fever and cough, and was diagnosed with acute leukemia by the hospital, and her 4-year-old daughter died due to ineffective treatment.
After his daughter was diagnosed with acute leukemia, Mr. Lin commissioned the municipal environmental monitoring station to monitor the air in the master bedroom of the new house, and according to the monitoring report, the formaldehyde content was 0.39mg per cubic meter, which exceeded the prescribed standard by four times.
In recent years, with the popularity of customized home furnishing products, most families will customize some home furnishing products when decorating, and some even the whole room furniture is customized. The topic of "formaldehyde" around customized products is also the topic that everyone is most concerned about.
"A well-known custom home formaldehyde exceeds the standard by 6 times!", "The child has a systemic allergy just after moving into a new home for a month". "The pungent smell of customized home furnishings does not dissipate for half a year"...... We have seen a lot of news reports like this, which makes everyone more worried about the problem of excessive formaldehyde in the room.
How much is the formaldehyde content exceeded? Do you know the normal range?
Nowadays, there will be indoor pollution in decoration, and in order to be able to move into a new home quickly and with peace of mind, more and more people are beginning to pay attention to indoor pollution control.
Therefore, after the decoration of the new house, formaldehyde testing will be done when preparing to move in, and now the detection has become an indispensable part of the move-in, so how many of the check-in indicators are qualified to move in?
Some say 0.1 mg/m, others say 0.08 mg/m. Which is correct? In fact, the state has long stipulated it:
"Indoor Air Quality Standard" GB/T188 83-20 02, this standard clearly stipulates that the standard value of formaldehyde is 0.10mg/m3.
"Standard for Indoor Environmental Pollution Control of Civil Construction Projects" GB 50 325-20 20, Class I civil construction engineering 0.07mg/m3, Class II civil construction engineering 0.08mg/m3.
There are generally two types of statements about formaldehyde: "odorless pungent" or "pungent odor" gas.
The irritation referred to here does not refer to how strong the smell is, the "taste" of formaldehyde generally refers to the stimulation of human respiratory organs under the condition of high concentration in the space.
Human susceptibility to formaldehyde is extremely low
The odor threshold of formaldehyde, that is, the lowest concentration that people can smell is 0.05~0.5 mg/m³, and the general odor or aroma concentration reaches 0.001mg/m³, which can be smelled by the human nose, and the olfactory threshold of formaldehyde exceeds the olfactory threshold of other odors by at least 60 times.
Formaldehyde "big households" have been exposed: these four daily necessities are rarely bought at home! Formaldehyde is released every day
One: Inferior leather sofa: a silent release of formaldehyde killers
Among the many home furnishings, sofas are a good place for us to relax and unwind. However, many people don't know that some low-quality leather sofas are one of the important sources of formaldehyde. These sofas usually use low-quality leather and glue, which contains a lot of formaldehyde. Moreover, the surface area of the sofa is large, and the formaldehyde release rate is fast, and long-term exposure to this environment is easy to cause a series of health problems.
2. Textiles: the potential threat behind softness
Textiles such as bedding, curtains, carpets, etc., are an integral part of our lives. However, some low-quality textiles may contain formaldehyde, which is due to the dye, glue, and the fibers themselves. In particular, newly purchased textiles will release a large amount of formaldehyde over a period of time, posing a potential threat to the health of family members.
3. Plastic products: a common but non-negligible source of formaldehyde
Plastic products can be found everywhere in our lives, from furniture to toys, from tableware to household items. However, formaldehyde is contained in some plastic products, especially some low-quality products. Formaldehyde will be released over time, polluting indoor air and posing a threat to the health of family members.
Four: paint, wallpaper and other wall decorations
In order to make the room more beautiful and warm, you will use putty to paint the wall, or even draw patterns, or paste your favorite wallpaper, and these wall decorations contain a lot of formaldehyde and TVOC, which will continue to volatilize with the rise of temperature, and inhaling a large amount of formaldehyde and TVOC is double harmful to the body.
In fact, when we remove formaldehyde, the most effective way is to use formaldehyde removal products, the use of products will not leave stains or marks on the furniture, and will not cause any harm to the family.
Therefore, you can rest assured that you can use formaldehyde removal products, provided that the products you use are guaranteed, and do not use inferior products casually. The following Xiaobian will share with you a few products that can effectively remove formaldehyde, the quality can be assured, it is Xiaobian himself who has used it, let's take a look.
1: Olvway formaldehyde scavenger:
Allova formaldehyde scavenger adopts a new "amino acid + photocatalyst" formaldehyde removal technology, which combines the characteristics of physical removal and chemical decomposition, and provides an innovative solution for the rapid and efficient degradation of formaldehyde molecules. The core is the integration of amino acid technology and photocatalyst technology. Its excellent scavenging efficiency can quickly penetrate and capture formaldehyde hidden inside structures such as plates, and then quickly decompose it into harmless carbon dioxide and water, and this decomposition process itself does not produce new harmful compounds, so it can effectively prevent the volatile release of formaldehyde from the source.
Olvway Formaldehyde Scavenger: The ingredients are safe and reliable, free of oxidants, alcohol and fragrance, and very safe for home use. Tested by professional testing institutions, the efficiency of this product to remove formaldehyde is as high as 91%, which is a favorable player for removing formaldehyde.
2: Activated carbon:
Activated carbon itself has a certain effect on the adsorption of harmful substances and volatile harmful gases, so it can be used to effectively adsorb formaldehyde, especially in the newly renovated indoor environment or in the case of excessive formaldehyde, it is an effective choice.
Three: Yiya formaldehyde deep scavenger: The composition of this formaldehyde scavenger is mild, which effectively improves the free state and the formaldehyde inside the plate, and the decomposition products are pollution-free.
