What is the standard value of formaldehyde detection? How can in addition to formaldehyde be effective?

According to the current indoor air quality standard GB 18883, the indoor formaldehyde concentration is less than 0. 1mg/m? To be qualified.

Indoor formaldehyde pollution is divided into long-term formaldehyde pollution and short-term formaldehyde pollution. At present, there are many methods in in addition to formaldehyde, but most of them can only remove short-term formaldehyde pollution, and the effect is not good for formaldehyde pollution in furniture and wood-based panels with a release period of 3- 15 years, so many methods in in addition to formaldehyde will rebound.

In addition to formaldehyde three-step method can be used to monitor whether the in addition to formaldehyde method is effective for a long time.

1. Choose furniture with independent space and use formaldehyde detection box to detect pollution sources;

2. Use corresponding indoor pollution control methods to remove formaldehyde;

3. Check the pollution source inside the furniture again and compare the formaldehyde concentration before and after.

Note: Because the formaldehyde release cycle in furniture is as long as 3- 15 years, long-term follow-up monitoring should be carried out to avoid rebound.
