How much does it cost to ask someone to test the formaldehyde in a new house

Formaldehyde detection in the new house is by point, how much is a point, if the requirements are not high, you can use the formaldehyde self-test box for sexual testing, formaldehyde has serious harm to the human body, when it is found that formaldehyde exceeds the standard, it must be dealt with in time, and several easy-to-use methods are recommended for everyone.

1.As long as the local air quality meets the standard, other pollutants will not be introduced, and it is easy to use and low cost, but it needs to be insisted on for a long time, because the release life of formaldehyde is long, and it is easy to repeat the situation when the ventilation is not smooth.

<>4.Putting some green plants at home can also effectively remove odors, especially pothos, spider plants, aloe vera, monstera, cactus, ivy, etc., which can effectively absorb harmful gases. In addition, large plants such as the Ping An tree and the camphor tree, which are more popular on the market, can release a fresh gas on their own, which makes people feel happy, and is also more suitable for removing the smell of new furniture.

5.The fresh air system is similar to the ventilation method of removing formaldehyde, but there is no need to open the window when in use, and the air delivered to the room is filtered, and it is also used when it exceeds the standard.

6.Professional formaldehyde removal companies can also quickly remove indoor formaldehyde and harmful substances, but because China's indoor air purification industry started late, there is no particularly strict scientific norms, in the fish eye beads in the formaldehyde removal company, there are many unprofessional and irresponsible companies, we must keep our eyes open when choosing

The region is not the same, the market is different.

20 square for a point, that is, a charging standard, the market ** in 350-400 yuan, 50 square meters of the case is defined as 3 points, then the charging standard will be 900-1000 yuan, small companies will probably charge 50-100 yuan for a point).

It can detect formaldehyde, benzene, ammonia, toluene, xylene, and TVOC harmful gases in indoor air.

Test results are generally available within 3-7 working days.

I don't know how much it costs to test formaldehyde in a new house, a friend's new house in addition to formaldehyde odor, after half a year, the effect is very good, according to my years of construction experience, there are several solutions to remove formaldehyde in new houses: 1. Activated carbon adsorption method.

Solid activated carbon has the characteristics of many pores, has a strong adsorption and decomposition effect on formaldehyde and other harmful substances, but is easy to saturate, Ye Guangni is a new type of activated carbon, containing graphene and SOD cellulase, will not be saturated, can be adsorbed and decomposed harmful substances.

2. Ventilation method.

The practical way is to ventilate, if the natural wind is not enough, enough, you can also use an electric fan as an auxiliary tool to speed up the movement of the airflow.

3. Plant absorption method.

Plants have a strong ability to absorb, such as cacti, spider plant, reed, ivy, iron tree, chrysanthemum, etc. Generally speaking, plants with large leaves and vanilla have a better absorption effect, such as spider plant, tiger tail orchid, etc.

1.A room is a point; 20 flat for a point ** at 350 400 yuan; 50 square for 3 points, ** at 900 1000 yuan. 2.Most of them are charged on a point-by-point basis, depending on the number and size of the rooms.

Formal formaldehyde treatment company: there are professional testing instruments, and the cost of door-to-door formaldehyde testing is generally 100-200 yuan per room.

Formaldehyde detection. $100 at a time. Mr. Pan, who lives in the Poly Ye Mansion, asked IKEA for testing, and after the inspectors came to the door, they set up a square air sampling instrument in the children's room. After 20 minutes, the test data is printed out on the spot.

The test results showed that the formaldehyde content per cubic meter of air in the room was milligrams. "The formaldehyde content is less than one milligram, even if it is qualified, the formaldehyde in your home is a little higher, just open the window to breathe, and there is no need for special treatment. The inspector charged Mr. Pan 100 yuan for the test and left.

1. The release rate of formaldehyde mainly depends on two factors, one is temperature, and the other is humidity, so we can use this characteristic of formaldehyde to use heaters, humidifiers, etc. to keep the room in a state of high temperature and high humidity, and then we can cooperate with ventilation or adsorption materials to absorb the formaldehyde that has been released at home.

2. There are a large number of irregular pores inside the activated carbon, among which the pores similar to the formaldehyde molecule will adsorb formaldehyde, which can achieve the purpose of purifying the air, but the number of internal pores is limited, and it may cause secondary pollution when the adsorption is saturated.

5. The fan can play the role of "inducing air" to accelerate the discharge of the gas containing free formaldehyde in the room to the outdoors, this method is only useful for the house with poor ventilation, and has little effect on the house with good ventilation effect

The cost of formaldehyde detection is generally about 100 yuan to 300 yuan. Formaldehyde detection has a great relationship with the area that needs to be detected, and the larger the area, the higher the cost. In addition, when conducting testing, if the testing institutions are different, then there will be a big difference.

Common formaldehyde detection tools include formaldehyde detection boxes, handheld detectors, and some companies engaged in formaldehyde testing services, as well as authoritative CMA formaldehyde testing institutions.

Problems that should be paid attention to when choosing a formaldehyde self-test box.

1. Qualified products developed by professional institutions and produced by regular large manufacturers should be selected. When buying online, it is best to choose a brand store that sells directly from the factory.

2. The product packaging is tight and strong. When buying online, don't just look at the ** and sales, but also look at the results of evaluation and feedback, and pay more attention to the evaluation of products.

3. When choosing a formaldehyde detection box, you must compare it carefully. First of all, it is necessary to choose machine filling to avoid too many human factors in manual workshop filling and inaccurate detection reagent dosage. Be sure to choose a glass bottle to prevent the plasticizer and reagent in the plastic bottle from reacting, resulting in the instability of the reagent.

Hangzhou Huankang professional testing, divided into formaldehyde single detection and detection of formaldehyde, benzene, toluene, xylene, TVOC five comprehensive testing. Formaldehyde detection is charged at 100 yuan per point; Formaldehyde, benzene, toluene, xylene, and TVOC are detected and charged at 300 yuan per point. Testing technicians collect air samples, and then send them to the laboratory for laboratory analysis and measurement of various data, and issue a test report with a technical seal, which can be issued within 3-5 working days.

The cost of formaldehyde detection is generally about 100 yuan and 300 points.

Professional indoor air pollutant testing should be measured on site with professional instruments, such as atmospheric sampling instrument, which can collect sulfur dioxide and particulate matter in the atmosphere, or hydrogen fluoride and particulate matter, etc., to facilitate the study of the relationship between sulfur or fluorine in gaseous and solid substances, and then use laboratory detectors and spectrophotometers to measure accurate values.

During the measurement process, it is required to close the detection environment for more than 8 hours (close doors and windows). Residents will be informed in advance not to add new sources of contamination during the testing process, such as moving in new furniture or other items, and recording the main items in the room. Carefully inspect the items that produce indoor pollution sources, such as office furniture, office supplies, wallpaper, tables, chairs, carpets, sofas and other items, and do a basic pollution source analysis.

Hello, about the testing of **, in fact, each city has some differences, you can actually consult the CMA testing agency in your city. Here's a rough look at the detection. (Take Hainan as an example).

Focus. 1. Formaldehyde testing should be carried out by a CMA qualified institution that only detects and does not govern, and the CMA test report is fair and objective and can be used as a formal occasion and legal reference, and there are doubts about the impartiality and objectivity of the unqualified test, and the report has no effect.

Focus. Second, formaldehyde testing, don't look for a company that does testing and treatment. Because our country's law stipulates that testing and governance are prohibited by the same company.

Specifically, please refer to the provisions of the national "Laboratory Qualification Evaluation Criteria": laboratories and their personnel may have an interest in the testing and calibration activities they engage in, as well as the data and results issued.

Focus. 3. Formal formaldehyde detection, only 200-500 yuan of formaldehyde is detected. (Take Hainan as an example).

Focus. Fourth, the common pollutants in newly renovated places are: formaldehyde, benzene, toluene, xylene, TVOC, ammonia, radon, etc., it is recommended to consider the detection of several substances.

Focus. Fifth, the detection point is set, generally an independent space as a point. If it is a family, such as a three-bedroom apartment, it is generally recommended to test three bedrooms and one living room at four points, and the kitchen and toilet are not recommended to stay in for a long time. If it is a large space, according to the standard, a detection point of 30-50 square meters is set up.

Of course, the time test can be planned according to the customer's budget and needs.

When choosing to identify whether the CMA formaldehyde testing company is regular, the main attention is the following:

1.Whether the qualifications are complete:

Check whether the company has a business license and CMA qualification certificate, and the business license registration address and CMA qualification certificate address, and the testing laboratory address are in the same place, which is formal. (It is recommended that if conditions permit, you can conduct an on-site inspection).

2.Whether it is a local CMA testing agency:

It is recommended to do CMA testing customers directly to find the local formaldehyde testing agency, if it is a testing agency in other places, especially ordinary family customers, the provincial testing company is prone to many problems in the testing process (such as formaldehyde needs to be sampled and analyzed within 24 hours, and the provincial one generally can't do it), so it is easy to have loopholes, and if it is used in a formal setting, it will be questioned and the report is invalid.

Look at the accuracy you want to detect, the more accurate the cost, find the quality supervision bureau and the environmental protection bureau large units to detect quite accurate, the cost is also very high, generally 30 square meters to about 400 yuan, to find the air quality company with a small testing instrument about 50-200 yuan, you can also buy your own formaldehyde test box to test on the Internet, the cheapest, of course, the error is also the largest!

If you want to be more accurate, you can set a separate point for the bathroom and kitchen, depending on your own wishes, because now many family kitchens have furniture of various materials, for your health, you can have a safe living environment.

The cost of testing in Beijing is different, if the test must identify the CMA testing agency, each point charges 300 yuan to 500 yuan to issue a report with legal effect, four points, the cost ranges from 1200 to 2000 yuan.

You can buy a formaldehyde detection machine to operate, this is also quite simple, if you call someone to come to the door to test, under normal circumstances, it will be two or three hundred yuan.

The general formaldehyde detection should be about 150 points, you must test three or four points, the better point is that they say there is CMA certification, this is expensive and bottomless. In general, the detection is one thing, but if the test result is exceeded, it means that it has to be treated, which can only be done by yourself, ventilation spraying Huankang nano aldehyde enzyme to maintain light, this is the best advice I can only give you.

There will be changes in different addresses, and there will always be a price difference between big cities and small cities, such as fourth- and fifth-tier cities, and the ** of a sampling point ranges from 100 to 300 yuan. Hopefully it can be adopted.

At present, there are only three formaldehyde testing institutions in Nanchang with CMA qualification: Nanchang Environmental Monitoring Station, Jiangxi Provincial Analysis and Testing Center, and Jiangxi Normal University Stanford Testing Center Station. The first two companies almost only test the unit, and the main detection direction is not formaldehyde. The testing center of Normal University is the most authoritative institution for home formaldehyde testing in Nanchang.

The most important ** is also relatively close to the people.

For a formal indoor testing agency with CMA qualification, it is generally charged according to the point, for example, a bedroom is a point, and under normal circumstances, it is about 500 yuan for a testing point, for example, your home is a three-bedroom and a living room, you need three bedrooms and a living room, that is, four points, and the four points add up to about 2000 yuan. Of course, some indoor air quality testing institutions may do activities, which will be cheaper.

Hope it helps!

The new house is renovated, the formaldehyde test is done, and there is a professional certificate in a professional institution, which seems to be calculated by the square.

Go to the environmental testing center for consultation, room, car ......**It's not the same, it's generally about 300, but it's worth testing for health.

You can buy your own formaldehyde detection instrument and then test it at home.

There are two types of home testing:

One is after moving in, home decoration or new furniture, want to measure indoor air quality, the reference standard is GB T18880-2002 [indoor air quality standard], there are five parameters: formaldehyde, benzene, toluene, xylene and TVOC, the cost is between 300 yuan and 500 yuan;

The second type of situation is that the standard for non-decoration is GB50325-2010 "Code for Indoor Environmental Pollution Control of Civil Construction Engineering", which has five parameters: radon, formaldehyde, benzene, ammonia and TVOC. The charging standard is 300 yuan to 400 yuan per point, and the standards implemented in each region are different, and the fees will be different.

Some places will implement landmarks, and some will implement the specific distribution of national standards.
