Formaldehyde is the most easily exposed chemical substance in daily life. Furniture, floors, clothes, air, and even food all have traces of it. Long-term inhalation of formaldehyde can cause various degrees of physical pathology and even cancer. So how to detect this chronic poison in time? Next, let’s talk about the detection of formaldehyde.

Formaldehyde detection refers to the " Indoor Air Quality Standard " and uses specific methods or instruments to quantitatively detect the formaldehyde contained in air, water, food, clothing, boards, leather, etc.

It is best to do formaldehyde testing for newly renovated houses and families with the following situations: families with pregnant women; families with newlyweds; families with children; families with elderly people at home.

The optimal time for formaldehyde testing - for civil construction projects, it should be carried out at least seven days after the completion of the decoration project and before the project is used; for personal decoration families, it is recommended that the test be carried out one month after the completion of the decoration project and one week after all the furniture is in place. Adequate ventilation should be ensured during this period to facilitate the dispersion of harmful substances and make the test results closer to the conditions during actual use.

Optimum closing time - For civil construction projects that use natural ventilation, testing and sampling should be carried out 1 hour after the external doors and windows are closed; when a dispute occurs, the closing time of the external doors and windows shall be 1 hour; for those who are preparing to move in or have already moved in When decorating a home, the stipulated time for doors and windows to be closed during testing and sampling is 12 hours, so the test results are closer to reality.

Determination of the number of sampling and testing points - the room usage area is 50 square meters, the number of testing points: 1; the room usage area ≥ 50 square meters and 100 square meters, the number of testing points: 2; the room usage area ≥ 100 square meters and 500 square meters, testing Points: no less than 3.

In addition to professional formaldehyde testing, we should also pay attention to frequent ventilation in daily life, and can properly cultivate some plants such as spider plants and pothos to absorb harmful substances, thereby improving indoor air quality.
