Which one is good for formaldehyde detection, and is formaldehyde detection reliable?

Qinhuangdao Impartial Indoor Environmental Monitoring Center, the most advanced treatment material testing tens of thousands of households, professional testing, certification certificate, is an authoritative testing.

Formaldehyde detection is also divided into many methods, there are formaldehyde detection boxes, as well as formaldehyde detectors, generally speaking, formaldehyde detection boxes are more convenient, the results may not be as accurate as formaldehyde detectors, but cheap, you can do more tests, once you find that formaldehyde exceeds the standard, it is necessary to treat it in time, the following is an introduction to several methods to remove formaldehyde for your reference.

1. The most common way to remove formaldehyde indoors is to open windows for ventilation, and this method has almost no cost. But the ventilation method also has disadvantages, first of all, the location of the house should be good to achieve the effect of ventilation, and secondly, the formaldehyde in the decoration materials is in a state of continuous release, and it is impossible to completely remove formaldehyde through window ventilation, it can only play an auxiliary role in removing formaldehyde.

2. Activated carbon to remove formaldehyde is the most commonly used way to remove formaldehyde in life, and the cost is low, but activated carbon is prone to adsorption saturation in a short period of time, and it needs to be replaced or dried after saturation. Another point to note is that if the amount of activated carbon is not enough, it will not play much role in removing formaldehyde indoors.

5. The air purifier used to be a high-end product, and the times have developed, and there is a trend of slowly going to the volume, because it is equipped with a fan inside, which can actively adsorb formaldehyde in the corresponding space, but it is recommended to buy products with formaldehyde removal function, and the formaldehyde filter element needs to be replaced regularly when used.

6. The fan can assist in opening the window for ventilation, many houses are not necessarily transparent, and the effect is not very good when the window is opened, so the fan can be used to accelerate the air flow in the room and quickly discharge the free formaldehyde in the air

Summary. The CMA agency detects formaldehyde, which is the most authoritative in China, and the state recognizes that its test report has legal effect. CMA formaldehyde detection has a complete and standardized formaldehyde detection process, with a single-point sampling time of about 20 minutes, and after sampling, it is brought back to the laboratory for laboratory analysis and a test report is issued, which can comprehensively measure the quality of air at home.

The CMA agency detects formaldehyde, which is the most authoritative in China, and the state recognizes that its test report has legal effect. CMA formaldehyde detection has a complete and standardized formaldehyde detection process, the sampling time of a single point is about 20 minutes, and the samples are brought back to the laboratory for laboratory analysis and analysis, and a test report is issued, which can comprehensively measure the quality of air at home.

The testing institutions with the CMA seal are nationally recognized laboratory institutions, they have nationally recognized laboratories and testing personnel, the authority is recognized by the state, they issue pure spine reports in court lawsuits, and the project acceptance is a legally effective primrose. However, the CMA's test report is expensive, and there is no special need for ordinary people, just one more stamp!

How much does it cost?

The charge for formaldehyde testing is 200-300 yuan for a point, and the charge for formaldehyde detection for professional CMA is 500 yuan for a point. Not only is the difference in the authority of the test report, but also has a lot to do with the detection accuracy.

Formaldehyde testing companies in each city are different, large companies must be more professional, once the formaldehyde is found to be exceeded, aldehyde removal is an urgent work, the following is for you to introduce some small methods of aldehyde removal, I hope you can efficiently control formaldehyde.

1. Using activated carbon is also a good choice. The surface of activated carbon is rich in pores, which can adsorb indoor odors, and also has a certain effect on pollution control, but the activated carbon treatment capacity is limited, and it will produce saturation after about half a month of use, and it is impossible to continue to work.

2. Green plants, aloe vera, cactus, pothos and other plants have a certain absorption capacity for formaldehyde, and can slowly consume the surrounding formaldehyde through photosynthesis. Because it is a plant, it is very safe and does not produce other harmful effects. However, it should be noted that the absorption of formaldehyde by plants is limited and can only be used as one of the comprehensive treatment methods to remove formaldehyde.

3. If you want to remove the indoor formaldehyde and odor as soon as possible, the first thing to do is to open the window for ventilation, and open the cabinet doors and drawers at the same time, and dilute and discharge the formaldehyde to the outside through air convection. Although this step is simple, it is also necessary to pay attention to the weather conditions, so as not to break the newly renovated home environment with strong wind and rain.

5. The principle of the fresh air system is ventilation, the fresh air outside is filtered and transported to the room, and then the harmful substances containing formaldehyde are discharged outdoors to achieve the effect of removing formaldehyde.

6. Photocatalyst is an auxiliary method for the treatment of formaldehyde, mainly because it cannot decompose formaldehyde in the dark or under lightless conditions, cannot operate around the clock, and its scope of action is small, and it cannot effectively remove indoor formaldehyde in depth. In addition, photocatalyst itself is a chemical and needs to be used with caution

Yichang Environmental Protection Monitoring Station, select an institution with the qualification certification (CMA) mark.

Yichang Environmental Protection Monitoring Station is a unit directly under the Yichang Environmental Protection Bureau, which undertakes the ecological and environmental quality monitoring of the urban area and the Three Gorges Reservoir area; Responsible for the supervision and monitoring of pollution sources in the city; Responsible for completing the directive environmental monitoring tasks issued by the environmental management department; Participate in the formulation of relevant policies and technical specifications for environmental monitoring in the city; Participate in the investigation of cross-regional environmental pollution accidents and the arbitration and monitoring of environmental pollution disputes.

According to China's laws and regulations, inspection and testing institutions that issue data and results with proof to the public shall obtain qualification certification in accordance with the law, and use the qualification certification (CMA) mark in the inspection and testing report. When choosing an inspection and testing institution, the public can pay attention to whether it has obtained qualification certification in accordance with the law and whether it has issued an inspection and testing report with the CMA mark.

Hello, the third-party testing agency with CMA China Metrology Certification is more authoritative.

Testing institutions with CMA seal are nationally recognized laboratory institutions. They have nationally accredited laboratories and testing staff. Authority is recognized by the state.

The reports issued by them are litigated in the court, and the acceptance of the project is regarded as a report with legal effect. However, the CMA test report is expensive, and for ordinary people, there is no special need, just an extra stamp.

1. It must be a professional testing approved by the relevant state departments to engage in testing business, and the "Notice on Carrying out Metrological Certification for Indoor Air Quality Testing Institutions" (hereinafter referred to as the "Air Quality Certification Notice") issued by the National Certification and Accreditation Commission stipulates that indoor air testing institutions shall pass the measurement certification and be announced to the public by the CNCA.

2. National standard testing methods and testing instruments must be used to ensure the reliability of the tested data, and indoor environmental testing methods and testing instruments specified by the state must be used.

3. Must have a special independent laboratory for indoor testing projects 4. Must issue a test report that meets national specifications and has a CMA mark 5. Must present the "Indoor Environment Testing Professional Qualification Certificate" issued by the state

Those who do not have the "Indoor Environmental Testing Professional Qualification Certificate" do not have the qualification to engage in indoor environmental testing.
