How to control formaldehyde in Changsha?

In fact, the control of formaldehyde in Changsha is very simple. The key is to find a professional prevention company. The method is to look at the original product test report of this control company (be sure to look at the original, and now many companies are based on the data in the PS test report). It's best to choose which company to control the in addition to formaldehyde effect of that product, because national authoritative testing institutions won't cheat people. At present, I compared several governance companies in Changsha. At present, as long as the formaldehyde removal rate of the test report of Hunan Dongzhan Technology Development Co., Ltd. reaches 92% (the removal effect is achieved after 72 hours, the longer the test time on the test report, the better the long-term performance of the product. Non-long-term product inspection reports generally only test the 24-hour in addition to formaldehyde effect). Therefore, I strongly recommend Hunan Dongzhan Technology Development Co., Ltd. to do formaldehyde control for everyone.
