Which is a good formaldehyde detection company in Fuzhou?

Indoor air testing had better find a professional and qualified environmental protection company. Indoor air testing is not only formaldehyde, but also toluene, xylene, ammonia and TVOC. Some companies may only test formaldehyde, benzene and TVOC, while others test all five items. The key is that the test data should be authoritative and reliable, and the test cost ranges from tens of yuan to hundreds of yuan. The charging standard of Fuzhou Dong Qi indoor testing is 300 yuan per point (a single room under 50 square meters is counted as one point), which is higher than other companies, and the test data is accurate. The test results are in line with the National Indoor Air Quality Standard (GB/T 18883-2002) and the Indoor Environmental Pollution Control Code for Civil Building Engineering (GB50325-200 1).
