How to remove formaldehyde after decoration

The newly decorated house will produce a lot of formaldehyde, and formaldehyde has great harm to the human body, so how should we get rid of formaldehyde? The most effective way to remove formaldehyde is to open more windows for ventilation, which is conducive to the volatilization and dilution of formaldehyde. Active carbon can absorb some formaldehyde substances, and formaldehyde scavenger can quickly remove the peculiar smell.

The harm of formaldehyde after decoration

Formaldehyde is generally released for 3 to 15 years, which is very serious for the human body, especially for infants, pregnant women, the elderly and patients with chronic diseases. Formaldehyde is mainly found in wall panels, ceilings, and other decorative materials, as well as all kinds of phenolic resin-based wood-based panels. Formaldehyde is also contained in wall cloth, wallpaper, paint and paint pipes. Therefore, furniture, chemical fiber carpets, curtains, sofas, cabinets, etc. if they are newly purchased, remember to put some formaldehyde purification products to remove them in advance.


Experts said that after the decoration, the room should be kept in a good ventilation state for three months so that volatile harmful gases can be released as soon as possible, and then it can move into a new home. However, only 80% of the rooms can be occupied after three months, and 20% of them need more time. It is necessary to know that many harmful substances are colorless and tasteless, but there is no smell or peculiar smell, which does not mean there is no pollution. For example, the benzene series does not have much irritant odor, but does great harm to the human body; radon, a radioactive gas, has no odor but can cause lung cancer.

How to get formaldehyde for the newly decorated house?

After decoration, the indoor formaldehyde test is best. The inspection shall be arranged at least 7 days after the completion of the decoration. Within 7 days, the concentration of volatile pollutants is the highest, and it can basically reduce to a stable state after 7 days, which is the best stage of detection. At the same time, the longer the external doors and windows are closed, and the higher the indoor pollutant concentration, the formaldehyde self-test can be carried out by using formaldehyde tester or detection box. The formaldehyde in the air reacts with the phenol reagent in the test box to form the zine substance and then forms the blue-green compound with the high iron ion oxide. Finally, the formaldehyde content is determined by the color depth ratio. According to the national regulations, the indoor content shall not exceed 0.1 mg / m3.

After the new house is decorated, it will move in after a period of time of airing. During this period, some formaldehyde removal items will be placed in the house, such as activated carbon (also known as bamboo charcoal) with adsorption effect, commonly used tea, and professional ones will be treated by air treatment companies. If formaldehyde is not serious, some natural flowers can also be put, such as rose, osmanthus, mint, ivy and iron tree, evergreen, Daisy, etc.

The most effective method of formaldehyde removal

  2. 2. Some fish can be raised because formaldehyde is a water-soluble substance, which can reduce the formaldehyde content in the air.
  3. 4. Some activated carbon can be placed in a proper position to absorb some formaldehyde, but the effect is relatively slow.
  4. 5. When a formaldehyde scavenger is used, it is necessary to select an air purifier that will not produce secondary pollution. For example, the effect of all is good. It can not only remove harmful gases such as formaldehyde quickly but also remove peculiar smell quickly.
