Dec 07, 2018

After the key was handed over to the new house, it began to be intensively renovated. Three months later, the house was ready to be renovated. However, even after the fire was celebrated, the owners were not suitable for the stay. Many pollutants are produced in home decoration. Commonly used are formaldehyde, benzene, ammonia, radioactive cesium, TVOC (total volatile organic compounds). Among them, formaldehyde benzene is the most mentioned, and it also causes the greatest harm to the body. The chronic toxicity of benzene has great damage to the body's hematopoietic tissue and nervous system, which causes leukemia.

What is the main source of formaldehyde in the new house? It is necessary to know that the volatilization period of formaldehyde is as long as 3-10 years, mainly because the glue used in the production process of new house furniture is the main source of formaldehyde, it is solidified, and the volatilization effect is relatively slow. In addition, benzene is contained in paints and coatings, and the damage is so fast that it is notorious.


Formaldehyde also has a safe concentration value. When it exceeds the safe value, it will cause great harm to the body. Let's take a look at the common symptoms of poisoning.

First, when the formaldehyde concentration reaches 0.06-0.07mg/m3, there will be slight asthma;

Second, when the formaldehyde concentration reaches 0.1mg/m3, there is odor and discomfort;

Third, when the concentration of formaldehyde reaches 0.5mg/m3, it can irritate the eyes and cause tearing;

Fourth, when the formaldehyde concentration reaches 0.6mg/m3, it can cause throat discomfort or pain. Higher concentrations can cause nausea and vomiting, cough and chest tightness, asthma, and even pulmonary edema;

5. When the formaldehyde concentration reaches 30mg/m3, it will immediately cause death.


How to remove formaldehyde as soon as possible?

Window ventilation

Some studies have shown that the indoor air formaldehyde concentration can be reduced by about 70% after opening the window for 10 minutes. Therefore, it is recommended to open the window ventilation when the weather is good.

Plant absorption method

Plants have a certain effect on formaldehyde adsorption. Cactus, hanging baskets, aloe vera, Clivia, green radish, etc., which are often seen in the flower market, are all ace-removed plants. However, it is necessary to remind everyone that the plant has limited adsorption capacity and should not hold too much hope on it.

Place natural bamboo charcoal or activated carbon

Natural bamboo charcoal is a lot of toxic substances. When we decorate a new house, we can buy some bamboo charcoal or activated carbon at home. Appropriate ones can be placed in each corner and in the cabinet to make it have a certain adsorption effect on the benzene series, but the effect on the adsorption of formaldehyde is not so obvious.

air purifier

In the category of electrical appliances, the air purifier is a good way to remove the aldehyde. The activated carbon filter in the machine has been upgraded and improved not only to effectively remove PM2.5, but also to adsorb formaldehyde.
