How to test for excessive formaldehyde in the room? Are there any netizens who are clear?

There is an "air formaldehyde self-test box" on the market, which can easily detect whether the formaldehyde content exceeds the standard at home. When formaldehyde in the air encounters the liquid in the test box, a chemical reaction will occur, causing the color of the liquid in the test box to change. The higher the formaldehyde content in the air, the darker the color of the liquid inside the test cassette.

Before using the air formaldehyde test box, 1. The doors and windows of the room to be tested should be closed for 2 to 3 hours. 2. When using, open the test box and expose the liquid in the test box to the environment to be tested for 40 minutes. 3. Compare the color of the liquid in the detection box with the formaldehyde display card to obtain the formaldehyde concentration range in the detected air.

4. If you test furniture, it is best to put the test box in the furniture. However, the air formaldehyde test box can only measure the approximate content of formaldehyde in the air, and cannot test the exact value. If you want to learn more about the accuracy of indoor formaldehyde content, you still need to ask a qualified testing agency to do the test.

Expectation can help you.

You can hire a professional indoor air treatment company to test the formaldehyde content in the new house.

Indoor air treatment companies generally have more accurate instruments and effective detection methods, which can accurately detect the content of formaldehyde in the room.

Use formaldehyde detection instruments to determine whether the indoor formaldehyde content exceeds the standard.

Hello, I'm glad to answer for you, the following is the answer to your query, I hope it will be helpful to you Detecting whether indoor formaldehyde exceeds the standard can be carried out by the following methods:1Buy Indoor Air Detection Instruments:

You can buy air detection instruments on the market, such as VOC detectors, etc., place the detection instruments indoors for about 24 hours, and then check the test results to determine whether the indoor formaldehyde concentration is higher than the national standard. 2.Please be tested by a professional organization:

You can ask a professional organization to conduct indoor air testing, and professional institutions usually use more accurate instruments for testing, and give a detailed test report, which can more accurately judge whether indoor formaldehyde exceeds the standard. 3.Use the DIY Rapid Test Method:

DIY rapid detection methods can be used, such as adsorbing formaldehyde in the air with ginger and other substances, and observing the color change of ginger after a certain period of time to determine whether the indoor formaldehyde concentration is higher than the normal level. However, the accuracy of this method is relatively poor and it is susceptible to other code delay factors, so it can only be used as a reference. Regardless of the method, it is advisable to close all windows and doors before testing and inspect indoors for a long enough time to obtain accurate results.

If the test result shows that the formaldehyde exceeds the standard, it is necessary to take corresponding measures to remove the indoor formaldehyde as soon as possible, such as ventilation, using activated carbon, etc.
