It is necessary to invite a professional testing and governance company, and the testing does not cost a lot of money. The maximum for three tests is 150 yuan.

First of all, the accurate detection method, the formaldehyde concentration detected by the house is based on the national standard 18883-2002, sealed for 12 hours, 10 liters of gas sample are sampled with phenolic reagent formaldehyde absorption solution, and then titrated to the end point of color development with chromogenic solution, detected by spectrophotometer, and finally calculated by converting the formaldehyde concentration under standard atmospheric pressure.
Institutions include: CMA Laboratory, a professional governance company. Laboratory personnel come to the door to collect samples, and then bring back the laboratory test report.
Our company provides self-service sample receiving and testing services, that is to say, customers self-service sampling, and then send it to the company for testing, which reduces manpower and material resources, and is also low, especially in the case of the epidemic restricting the flow of personnel, this is a very good choice.
Secondly, the formaldehyde self-test box is a semi-quantitative detection method. This unpredictable problem has been mentioned in many articles, so I won't say much about it here.
In addition, portable formaldehyde detectors are not recommended. I can't say for sure.
1. Formaldehyde self-test box.
The formaldehyde self-test box is more convenient to use, it is a way to compare the color card, and it should be noted that the color card has color difference, so it is not particularly accurate when interpreting the value.
2. Civil formaldehyde detector.
Civil formaldehyde detector is the principle of the sensor, which can read the data in a few seconds after starting, and it is more convenient to use, but the detection method of the sensor principle is easy to be interfered with and cause errors.
3. Formaldehyde testing institution.
Formaldehyde testing institutions generally use phenol reagent spectrophotometry to detect formaldehyde, and the doors and windows need to be closed for 12 hours before the test, and the detection formaldehyde data is lower than the standard. This is currently the most accurate indoor formaldehyde detection method.
If the detection of formaldehyde exceeds the standard, then it is necessary to consider removing formaldehyde, and the formaldehyde content such as formaldehyde is reduced to within the national standard before moving in.
Interior decoration has formaldehyde, this thing is also with the improvement of people's living standards so that every household is paying more and more attention to environmental protection and health, if you choose no decoration pollution furniture, or still find a company to remove formaldehyde, I think the company in addition to formaldehyde is to let you waste money, this is not to solve the source and fundamental, need to start from healthy furniture, no formaldehyde furniture, environmentally friendly furniture, such as the choice of diatom mud as wall paint, this is a more environmentally friendly coating, And it also has the function of adsorption and purification of formaldehyde, I hope I can give you a little advice.

As we all know, formaldehyde, benzene, xylene, toluene, and TVOC are the main culprits of indoor air pollution, but most of the decoration owners do not know how to judge whether the indoor air quality of their homes meets the standards for safe occupancy, and whether there will be excessive formaldehyde, which makes them worry every day.
Method 1: Formaldehyde testing is carried out to determine whether the indoor formaldehyde exceeds the standard.
The test strip box for formaldehyde detection is a common way to detect indoor formaldehyde content, this is because the test box is cheap, and it is easy to operate, but the error of the test box is relatively large, and the test box can only measure an approximate formaldehyde concentration range, but the standard of indoor formaldehyde should be in the last two decimal places, but the formaldehyde test box also has a certain effect, after all, it can know a general range of indoor formaldehyde concentration, that is, whether the indoor formaldehyde concentration is high or low, before testing with the formaldehyde detection box, You need to close the doors and windows for 1 hour in advance, and then put the reagent in the room to test the part for absorption, put it for 20 minutes and pour the absorption solution for dilution, and then wait for ten minutes The kit will change color, and then compare the approximate range of formaldehyde concentration through the color card, so that the result is only an approximation, if you want to know the specific value of indoor formaldehyde concentration, this requires a professional formaldehyde removal company to conduct atmospheric sampling, and then through the laboratory to know the accurate results!
Method 2: Use the symptoms of body organs to perceive whether indoor formaldehyde exceeds the standard.
If you stay indoors more pungent, it means that indoor formaldehyde is seriously exceeded, at least more than 4 times more than the safety standard, if you stay indoors for a long time, the body will feel dizzy, it means that the indoor formaldehyde exceeds the standard by more than 3 times, if you stay indoors for a long time will feel the eyes astringent, it means that the indoor formaldehyde content exceeds the safety standard by more than 2 times, if you just feel the dry throat, it means that the indoor formaldehyde is only slightly exceeded, but it is unsafe to use the body to perceive whether the indoor formaldehyde exceeds the standardJudging whether indoor formaldehyde exceeds the standard, it is still necessary to know through the professional testing equipment of the formaldehyde removal company, so it is just a little money, at least the body will not be harmed by formaldehyde!
If after the detection, indoor formaldehyde is in excess of the standard, it is necessary to carry out measures to remove formaldehyde in time, of course, it takes a long time to remove formaldehyde by yourself, and there is no effect, only a professional formaldehyde removal company can do a truly effective rapid removal of formaldehyde!

You can buy a pot of green plants and put them at home, if the leaves turn yellow soon after two days, it means that the formaldehyde in the room exceeds the standard.
-
Do you mean the smell of decorating a new house, in fact, it is not only to remove the smell, but also to eliminate harmful substances such as formaldehyde. It is completely possible to spray Huankang nano aldehyde enzyme to treat, remember to ventilate during this period. Also, if the light is not good, then turn on the lights and don't save electricity.
-
Formaldehyde rapid test strips.
The reaction part of the front end of the test strip is yellow, and the reaction part of the test strip is darker yellow. It means that the concentration of formaldehyde in the room is higher; When the reaction part of the test strip is light yellow, it means that the concentration of indoor formaldehyde is low, and the general value should be read out with reference to the standard color card to determine whether the indoor formaldehyde concentration exceeds the standard or the general range of the standard.
-
The best way is to use a formaldehyde measuring instrument to measure, because it is impossible to tell whether formaldehyde exceeds the standard by the nose alone, and the formaldehyde content can be accurately measured by measuring with an instrument.
-
With the formaldehyde test box, the principle of the formaldehyde self-test box is generally to use chemical adsorbents to quickly adsorb formaldehyde components in the air. Then, through the color reaction, the formaldehyde content in the indoor air is roughly estimated by comparing the colorimetry. It is characterized by convenience and speed.
The disadvantage is that the values are not accurate enough and are susceptible to interference by factors such as temperature, humidity, air pressure, surface area of the detected liquid, and air velocity. If the formaldehyde exceeds the standard, it is easy to treat, and it is useful nano live ore in my home. It works well.
-
It can be judged by the sense of smell, and if the indoor smell is strong and pungent, it can also be judged by formaldehyde detection tools.
-
There are many formaldehyde detection methods, you can find a special company or you can test it yourself, a special company is very expensive, you can buy a formaldehyde test box for your own testing, it is very cheap and convenient, the results are obvious, if there is no formaldehyde to save trouble and effort, if there is formaldehyde, find a way to remove formaldehyde, I have several ways to control indoor formaldehyde pollution: 1. More ventilation, which is the most fundamental way to purify indoor air. 2. Place green plants to purify the air and beautify the environment and mood.
3. Placing Maya blue, a formaldehyde removal material, can effectively adsorb the five major pollution culprits in the air. 4. Use formaldehyde scavengers. 5. Please remove formaldehyde from the company to control formaldehyde.
6. Using an air purifier is too expensive.

Determine with formaldehyde test box, in addition to formaldehyde to ventilate, decoration is best more than half a year in the stay, if you have to be in a hurry to live can use other methods, open doors and windows to release formaldehyde odor, pay attention to the time and method, otherwise it will cause cracking of the wall, affecting the decoration effect. Plant purification method, the most common indoor plants are aloe vera, spider plant, tiger tail orchid, one-leaf orchid, monstera bamboo, they can remove harmful substances in the air, especially formaldehyde. However, squeezing my experience in removing formaldehyde, in fact, there are many ways to remove formaldehyde, such as herb Di () Yalin is very desirable, the times are developing, science and technology are innovating, and there are more and more ways to remove formaldehyde, but we also have to have a few more eyes, and what suits us is the best.

You can purchase a machine self-test box for your own testing.

Formaldehyde is very harmful to the human body, causing allergies, cough, dizziness, headache, eye discomfort and other symptoms, and inducing diseases. Therefore, if formaldehyde exceeds the standard, we must find a way to remove formaldehyde.
There are many ways to remove formaldehyde, such as the following:
1. Open windows for ventilation.
At least for more than half a year, if you can, open the windows, open all kinds of cabinets in the house, and use electric fans to blow more at home to promote air circulation. However, after half a year of ventilation, formaldehyde may also exceed the standard, so it is not possible to just open the window for ventilation.
2. Green plants. The effect is not great, but it can be used, at least to beautify the house.
3. Activated carbon pack.
To be honest, it is also limited, but it is better than not using it. Remember to replace it regularly, otherwise the formaldehyde it adsorbs will be re-released, causing secondary pollution.
4. Find a professional organization to remove formaldehyde.
Don't look for it if it's not professional, you must be professional or unprofessional.
5. Air purifier.
This can help, but it should be used sparingly, as the filter needs to be replaced regularly.
-
Visual inspection of the color of the sample reagent tends to be close to the color level, which can be regarded as mild formaldehyde exceedance.
You can open the window for ventilation every day to remove the free formaldehyde, and you can also use activated carbon packs for adsorption, remember to replace it every once in a while.
If it has just been renovated, you also need to pay attention to:The formaldehyde volatilization period is generally as long as 3-15 years
There may not be a major problem in a short period of time, but with the continuous volatilization and release of formaldehyde, the concentration of formaldehyde in the indoor air will become higher and higher.
For free formaldehyde, ventilation and activated carbon adsorption methods can be used, but other methods need to be taken for formaldehyde in the source, such as:
1. Formaldehyde removal spray:Self-purchased aldehyde removal spray spray on the surface of the pollution source can play a role in inhibiting the decomposition of formaldehyde, but be cautious when purchasing, because the quality of the current right removal products on the market is uneven, and if you buy defective products, it may also aggravate the pollution.
2. Professional Governance Institutions:It is also possible to find a professional formaldehyde treatment agency, and the equipment and chemicals they use in construction are more reliable, after all, no one wants to smash their own signboards. It's just that in terms of governance costs, it must be relatively higher.
-
It's not over-the-top. Open more cabinets, open doors, open windows, and let in the air.
Now there are many companies that have instruments for you to test, and the state stipulates that formaldehyde below is qualified. Now the decoration is qualified, the furniture is qualified, but put together, they are slightly released, and it will exceed the standard. Good people state air purification, is now engaged in activities, free testing, you can learn about it.
Jincheng Environmental Protection teaches you a few simple and practical ways to remove formaldehyde. >>>More
The national standard is that it is already seriously exceeded, and it must be treated in a timely manner, because formaldehyde is continuously volatile, and the release life is relatively long, and the release life of formaldehyde in some materials can even reach 3 to 15 years, so it is difficult to completely remove it in a short period of time. >>>More
If an accurate test only needs an analytical instrument, if you feel particularly smoked at home, it is recommended to find a special testing institution.
Greini's air catalyst removes formaldehyde and has a good effect.
