How much is an indoor formaldehyde test Indoor air testing items are

Indoor formaldehyde detection requires about 300 yuan, and indoor air testing items include formaldehyde, benzene, radioactivity, total volatile organic compounds, and radon.

There are five main indicators (formaldehyde, benzene, radioactivity, total volatile organic compounds, and radon) for indoor air testing. There are currently two standards for indoor air quality in China, GB50325 and GBt18883, of which GB stands for national standard and T stands for recommendation. For indoor air quality testing, the indoor air testing items specified in both standards are the same.

Standard measurement method for ammonia in ambient air, air quality. Determination of carbon monoxide by non-dispersive infrared method. Standard method for sanitary inspection of benzene, toluene and xylene in the atmosphere of residential areas by gas chromatography.

The release life of formaldehyde is very long, the release source is very wide, it is easy to exceed the formaldehyde standard when the ventilation is not smooth, in addition to formaldehyde company really has not been used, I have been using a variety of methods to combine, to remove formaldehyde myself, I will use the method I write below, I hope to help everyone.

1. Putting some green plants at home can also effectively remove odors, especially like pothos, spider plant, 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.

2. Open doors and windows to make the air circulate naturally, and discharge harmful gases to the outside through air flow, which is simple and effective. Try to keep the windows open for ventilation indoors for a long time, and you can also use electric fans to assist in accelerating indoor and outdoor air convection flow, forced ventilation for a month, and the decoration taste will be greatly reduced. It is best to place the newly purchased furniture at the ventilated outlet, so that the odor is directly excluded outside.

3. 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. We all know that formaldehyde is volatile at high temperature, and we can use some heating equipment to increase the temperature at home a lot, so that formaldehyde gas can volatilize in large quantities, and then formaldehyde can be removed by opening windows for ventilation. Repeated operation a few times, you can remove most of the formaldehyde in the home, but we must pay attention to safety when using heating equipment to avoid fire.

6. The fresh air system can introduce fresh air outside and discharge harmful substances from the room through the system's filtration device during the period when the window cannot be opened, which will reduce the concentration of free organic pollutants in the indoor space to a certain extent and accelerate the release rate of pollutants. Through continuous circulation, the indoor decoration pollution is controlled

Different methods will have different **, an affordable formaldehyde test box may be enough for a few yuan, and if you find a regular formaldehyde testing company to make a CMA report, it will be slightly more expensive, a few hundred yuan or about 1000 yuan. However, no matter what method is used, if the indoor formaldehyde content is detected to exceed the standard, it is necessary to remove the indoor formaldehyde as soon as possible. There are many ways to remove formaldehyde, so let's share with you a more practical way to remove formaldehyde at home.

1.Opening windows for ventilation is a zero-cost method for indoor formaldehyde removal, and it is also a more practical method. However, the ventilation method also has many limitations, which has a certain relationship with the house type and location, and the formaldehyde release life in the decoration materials is very long, only using the method of opening the window to ventilate the indoor formaldehyde problem is too slow, and the ventilation method can only be used as an auxiliary method to control formaldehyde.

2.The use of green plants to purify formaldehyde is a very promising way to remove formaldehyde, plants will adsorb a part of formaldehyde during photosynthesis, but the absorption is extremely small, and it is recommended as an auxiliary method when removing formaldehyde.

3.Activated carbon is a traditional physical adsorption material, which has been well received in the treatment of indoor and outdoor pollution, its specific surface area is large, and it has a strong adsorption capacity, but its adsorption capacity is limited, and it does not have the function of decomposition.

4.There are many types of air purifiers on the market, and most of them are harmful substances such as odors, bacteria, and allergens, and have no treatment effect on formaldehyde, toluene, and TVOC produced in the home improvement process. Even if a small part of the air purifier can remove indoor formaldehyde, its range of action is relatively limited, there is no doubt that the use of air purification to treat indoor formaldehyde is not cost-effective.

5.There are many formaldehyde removal companies on the market, many methods and technologies are also uneven, and some companies are easy to repeat after governance, which is also the reason why everyone has mixed opinions about formaldehyde removal companies, and it is recommended to hire a big brand of aldehyde removal companies, so that the later effect can be guaranteed.

Formaldehyde is released for a long time, and it is often difficult to control formaldehyde in one way, so if you want to better deal with formaldehyde, you still need to combine a variety of methods, so as to show a better aldehyde removal effect!

The charging standard is 900 yuan for benzene and toluene.

Generally speaking, there is a standard for indoor air testing, the charging standard is about 900 yuan for benzene and toluene, and the charging standard for other formaldehyde and ammonia items is about 1200 yuan, and the charging standard for benzene, formaldehyde and toluene is about 1500 yuan.

The detection is also determined according to the room area, if it is less than 50 square meters, you can set up a detection point. If the area is 50-100 square meters, then it is necessary to design 2 detection points, and when the area is about 100 square meters, it is necessary to set up 3-5 detection points, and these costs have not been added to the door-to-door fee of 100-200 yuan.

Formaldehyde detection depends on what method is used.

Formaldehyde self-test box, purchased from the Internet, according to the instructions for use of your own testing, is characterized by saving money and convenience, but the relative error is also higher than the other three types of testing standards. djj

Professional things to be done by professional people, but in addition to the formaldehyde industry is an exception, because in addition to the formaldehyde industry is mixed, we ordinary people are difficult to distinguish, in the face of the problem of formaldehyde removal is easy to be some no technology and ability to remove formaldehyde companies fooled, not only waste money, but also formaldehyde excess and other problems can not be solved, in the choice of formaldehyde removal company, we still have to keep their eyes open.

4.Choose plants that can adsorb formaldehyde, pothos, aloe vera, spider plant and other plants can adsorb a certain amount of formaldehyde pollution, and can indeed remove formaldehyde. Placing some greenery in your new home can also help to beautify the room and freshen the air.

However, the adsorption capacity of plants is relatively limited, and if the formaldehyde concentration is too high, the plants will wilt and die.

5.If you want to eliminate formaldehyde in the house as soon as possible, you can put a floor fan at home after the decoration is completed, and open the window for ventilation at the same time, if the outdoor wind allows, the fan can increase the flow speed of indoor and outdoor air, reduce the indoor formaldehyde content, and speed up the release of formaldehyde, it may be the most effective and low-cost way.

6.In the case of high temperature, it can promote the conversion of formaldehyde in the bound state into free formaldehyde and reduce the total content of formaldehyde, because formaldehyde penetrates deep into the board, although formaldehyde cannot be completely removed, but its effect is still very obvious

Formaldehyde detection fee charge reference:

At present, the cost of formaldehyde testing in the market is more formaldehyde, and friends who have formaldehyde testing needs in the near future may wish to pay attention to it.

A room is a point;

20 square meters for a point, that is, a charging standard, the general testing market ** in 150-200 yuan, CMA testing 400-600 yuan;

In the case of 50 square meters, it is defined as 3 points, and the general testing fee will be 450-600 yuan, and the CMA testing fee will be 1200-1800 yuan;

Formaldehyde testing cost, most of the testing companies in the market are charged according to such points, according to the number of rooms and the size of the room to divide the point, and finally charge for measurement.

According to the current formal testing institutions to detect formaldehyde fees, the cost is generally between 100 yuan and 500 yuan for a testing point, generally within 20 square meters for a charging standard, and the cost is so different from each other, it is mainly affected by the region, the quality, effect and service of formaldehyde detection, so we should not only pay attention to the cost of testing formaldehyde when choosing, but also pay attention to the factors that affect the cost, so as to obtain accurate test results at a lower cost.

There is a big difference in choosing different formaldehyde detection methods for a formaldehyde test.

Professional testing generally does not provide a single formaldehyde detection, must be tested at the same time a pollutant project, public institutions testing institutions to test a point charge of about 600 yuan, a room in the room is a testing point, at least two points need to be tested, and private testing institutions also need to test a point of about 300, so the cost of a professional testing fee is at least 600 yuan.

If you buy a formaldehyde self-test box for 600 yuan, you can buy at least 200 self-test boxes.

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!

Decoration air testing process: In strict accordance with GB T18883-2002 and GB50325-2010 standards, the testing personnel will come to collect air samples, laboratory testing and analysis, senior engineers will review and sign, and issue test reports; The cycle is about 3-4 working days.

1. The importance of laboratory testing for formaldehyde and other pollutants: Formaldehyde testing in new houses is related to the life and health of you and your family, and you must experience a rigorous and complex experimental process in order to get scientific test results; The instrument that can measure formaldehyde on the spot is not scientific, the instrument cannot pass the CMA measurement certification, and its cost and reagents are relatively low, so it is mostly free or low-cost testing, and formaldehyde is detected for treatment; It cannot support the protection of life and health.

2. What to do if the formaldehyde detection exceeds the standard: our center will tailor it according to your detection value and decoration situation; While doing a good job of component analysis, trace back to the source of pollution, and give you a scientific solution and recommended use time.

3. What kind of suggestions will the industry authorities give about the removal of formaldehyde: the traditional formaldehyde treatment process is mostly high-temperature fumigation, spraying aldehyde remover, spraying photocatalyst, releasing ozone, etc.; Such processes can produce secondary pollutants as well as corrosive furniture. Formaldehyde is generally used as an adhesive, mostly existing in the inside of the board, so it cannot be used; Moreover, indoor pollutants are not only formaldehyde.

Now most cities have companies to test formaldehyde, the cost is about 500 yuan, if you find a CMA qualification, the cost is about 2000 yuan. There are also ** institutions that also have testing, such as the Environmental Protection Bureau and the Health Bureau. The cost mainly depends on which city you are in, and small cities are definitely cheaper

Now there are companies that detect formaldehyde, and the testing cost is not expensive, no more than 500 yuan.

There are two ways to test indoor air (formaldehyde, benzene, TVOC):

First, the data can be produced on the spot, and the error is relatively large;

Second, the samples were returned to the laboratory for analysis, and the data ratio was accurate;

There are many places to do it, and there are many activities to do the test that are free, welcome to ask.

Pothos nano - formaldehyde detection and management.

The indoor formaldehyde detection in the home is generally at 300-500 points! For example: a two-bedroom house, at least 3 points must be detected, that is, two rooms each detect a point, plus a living room, the general kitchen and bathroom have to be according to their own needs, can be measured or not, after all, 3 formaldehyde detection points have to be about 1000, local tyrants at will!

1: Authoritative CMA formaldehyde testing agency

Indoor formaldehyde testing We all know only one mark, that is, the CMA test mark, which has a credible testing agency. In some litigation channels, only test reports with this mark are credible and can be used as a legal basis, so do you know how to find a professional formaldehyde testing agency?

2: Formaldehyde self-test box and formaldehyde detector

But now that the Internet is very developed, you can also buy a lot of things, such as formaldehyde self-test boxes and formaldehyde detectors. These things can also be used to detect formaldehyde, but since these are used by the customers themselves, the results show that there is no credibility either scientifically or legally, so how can we detect numbers that are truly credible? On what basis?

How to distinguish the real authority of the inspection body?

That being said, how is CMA's formaldehyde testing different from our own? The difference is obviously significant. It is necessary to know the concentration of formaldehyde detection.

In general, this is not always possible. Ideally, the test is to be able to mimic the usual conditions of home life, so it is usually tested professionally before sampling. Remind the customer to first do a 12-hour house confinement work in order to simulate our nightlife environment as much as possible, and then return to the laboratory for detailed analysis after sampling to ensure the most accurate formaldehyde concentration value, we test it ourselves obviously it is not so rigorous, there may be too many factors that can affect the results, so it is still necessary to let the professionals do it now.
