    The differences between the formaldehyde self-test box and the formaldehyde box are as follows:

    The formaldehyde self-test box is usually about a dozen yuan, and the formaldehyde box needs hundreds of yuan.

    The formaldehyde self-test box and formaldehyde box are very easy to operate, and they can be used according to the instructions.

    The formaldehyde self-test box can detect whether there is formaldehyde, but the accuracy is not enough, and there is a certain error; The formaldehyde box can also detect formaldehyde, and there is also an error. (The owner's self-test method has a high probability of error due to operating methods, differences in environmental conditions, human activities, products, etc., and the enterprise is in a fixed constant temperature and humidity environment when testing, which cannot be guaranteed at home).

    For formaldehyde detection, it is more reliable to choose a CMA institution or a formaldehyde treatment company, and the data is also credible.

    The biggest advantage is that the test results are accurate, take the SGS indoor formaldehyde detection box as an example, the sample is analyzed under professional equipment, and the result is ***.

    Pick a test box and generally look at these three points:

    1.It is best to add an anti-interference agent, because there are many impurities in the air, which can interfere with the test results and cause inaccurate results. The function of the anti-jamming agent is to eliminate the interference of these impurities. Therefore, it is necessary to choose a detection box with an anti-jamming agent.

    2.Be sure to buy the glass bottles. There are two bottles of testing liquid in the test box, and many small manufacturers use plastic bottles to fill the test liquid, because plastic bottles are cheap.

    However, the plastic component will react with the test solution for a long time, which will have a negative impact on the test result. The glass bottle is much better, and it will not leak, but the cost is a little higher.

    3.Mechanical filling. The test box is very precise, and it must be filled mechanically to achieve this accuracy.

    Why emphasize mechanical filling, because I have bought many test boxes, found that a considerable part of the amount of products are uneven, either this box more, or that box less, it is estimated that this is the small workshop workers manual filling, the test results can be imagined how inaccurate. Therefore, you must buy mechanical filling, observe before use, whether the amount of reagents in each box is the same, if the amount of reagents is different, then it may be hand-loaded, and the test is not accurate. The Qingyi test box is good.

    The formaldehyde test box is developed by the Chinese Academy of Inspection and Quarantine, and is based on the "phenol reagent colorimetric method" of national standard detection and sampling, which is one of the chemical test methods specified in the "national standard" for indoor air formaldehyde detection issued by the national quality supervision department.

    Therefore, from the perspective of the research and development principle of the formaldehyde self-test box, it not only has a scientific basis, but also conforms to the chemical test methods specified in the national standards.

    So far, the test is relatively accurate.

    Formaldehyde test kits may be the best choice for testing formaldehyde at home, and this method is simple and economical, and it can be bought online and convenient. If the indoor formaldehyde detection exceeds the standard, the following methods are also more suitable for home aldehyde removal.

    1. Wise Stone.

    It is currently a relatively cost-effective formaldehyde removal product, its advantage is that it can be decomposed into water and carbon dioxide at the same time of absorbing formaldehyde and harmless substances to the human body, because of its decomposition characteristics, so that it will not appear adsorption saturation and indoor secondary pollution, and suitable for various types of environmental use. In addition, its removal rate is also dozens of times that of traditional adsorbent materials. When choosing, it is important to note that it is a gray ore with an irregular shape and is not a round particle.

    2. Plants.

    Plants are the best products provided by nature to remove formaldehyde, and the more respected ones on the market are: pothos, spider plant, ivy, and aloe vera. These plants are a combination of beauty and talent, both to decorate the home and to purify the air.

    3. Open windows for ventilation.

    Opening windows for ventilation may be the easiest and fastest way to remove formaldehyde, but the most important premise of ventilation to remove formaldehyde is to maintain ventilation, where ventilation is not simply to open the window, the most important thing is to achieve indoor and outdoor air convection, so as to achieve the effect of removing formaldehyde. For example, in summer and winter, when the air conditioner is turned on, the doors and windows are closed or there is no wind outside, the effect of removing formaldehyde cannot be achieved

    4. Formaldehyde remover.

    Formaldehyde scavenger is the use of chemical or biological principles, formaldehyde decomposition into harmless carbon dioxide and water or other harmless substances, so as to achieve the purpose of purifying formaldehyde, but there are many manufacturers, the quality is also uneven, you must keep your eyes open when buying, otherwise it is easy to cause the introduction of other harmful substances.

    Fifth, the fresh air system.

    The fresh air system can ensure that the home is in a ventilated state 24 hours a day, which can greatly increase the exchange of indoor air and the outside world, although the effect is very good, but the first time of this fresh air system is more expensive, and it is a better choice to install it before decoration.

    Most of us are office workers, and time is very limited, so if you want to remove formaldehyde from the air as soon as possible, it is best to do it in a variety of ways at the same time.

    Generally, you can go to the decoration company or go to the building materials market to sell, the simplest is to buy formaldehyde detection box on the online platform is a very common thing, generally use the formaldehyde detection box to do the test to put the detection liquid into a container, when the air flows through the surface of the detection liquid, the formaldehyde is completely absorbed, the color of the reagent is yellow when the formaldehyde detection box is used, basically does not contain formaldehyde, and the general yellow-green yellowish is not exceeded.

    Now there are more on Tmall, test the principle of formaldehyde Formaldehyde reacts with phenol reagent to form azine, which is oxidized into blue-green compounds by ** iron ions in an acidic solution, and is quantified according to the color shade and colorimetry. Qingyi test box is good.
