Dry goods are full! Air purifiers in addition to formaldehyde in the end is not reliable?

In addition to the problem of formaldehyde in newly installed houses, the owners have a headache. In addition to the daily window ventilation, the use of charcoal bags, air purifiers have become a 'de- aldehyde artifact' for many people.

According to the new national standard "GB/T18801-2015" for air purifiers, CADR is the amount of clean air, which is the parameter for the purification ability of target pollutants. It indicates the rate at which the air purifier provides clean air. Then it is judged that the air purifier is not dependent on formaldehyde. Is it enough to look at formaldehyde CADR? Actually it is not!

Because the CAD value of formaldehyde is measured in a closed experimental chamber with an initial concentration of up to 1 ± 0.2 mg/m3, which is about 10 times higher than the national standard!

To know that formaldehyde reaches 0.6mg/m3, it may cause discomfort or pain in the throat. When the concentration is higher, it may cause nausea and vomiting, cough and chest tightness, asthma or even pulmonary edema. And the World Health Organization sample survey shows that the average formaldehyde of newly renovated families in China The concentration is 0.238mg / m3 (compared to the initial concentration of formaldehyde in the laboratory is a low concentration of formaldehyde), people do not come into contact with the concentration as high as in the laboratory! In addition, in the experimental cabin is a high-injection of formaldehyde at a time 4. In the daily life, formaldehyde is slowly released and gradually accumulates beyond the standard range.

This also shows that only looking at the formaldehyde CADR to judge the performance of the air purifier in addition to formaldehyde is far from enough, it is best to use a more stringent, more objective, closer to the real home environment, in addition to low-concentration formaldehyde detection and continuous Low-concentration formaldehyde detection released. At present, there are air purifiers for these two tests, but only the new ones who insist on winning with quality and innovation. The new one dares to try this more rigorous and objective detection. The way also undoubtedly played a good demonstration and guiding role for China's air purifier industry.

The two major tests are under the sole authority of the Chinese Academy of Sciences, and the air purifiers under test are from a new generation of products developed by Xinyi, Xinyi Xiaobai PRO. When it comes to Xinyi Xiaobai PRO, this is a wide-ranging industry. Known as the 'Performance Monster', the 'Black Horse' air purifier not only has a composite filter with a total area of ​​up to 7 square meters, but also has a CADR value of up to 400m3/h (measured 570m3/h) and innovative The box is separated from the linkage, wireless charging and other designs. So, in the two major tests, what is the performance of the new Xiaobai PRO?

In the detection of low-concentration formaldehyde, in order to be close to the actual situation that the formaldehyde in the new home is about 2~3 times higher, a low-concentration formaldehyde of 0.25 mg/m3 is injected into the standard test chamber of 30m3 (compared to the conventional test, the formaldehyde is about 10 times higher than the standard). In terms of initial concentration).

At the highest level, Xinyi Xiaobai PRO reduced the concentration of the test chamber to 0.04 mg/m3 in just 7 minutes, and as low as 0.01 mg/m3 after 18 minutes, which is already the lowest range of the test instrument. Even at the lowest wind speed, the new Xiaobai PRO reduced the formaldehyde concentration to 0.04mg/m3 in just 15 minutes, and then controlled to 0.01 mg/m3 in 17 minutes. Whether it is high wind speed or low wind speed, Xinyi Xiaobai PRO removes formaldehyde is still fast and thorough!

In analog The aldehyde is continuously released from the environment. In addition to the formaldehyde capacity test, 30 μL of formaldehyde solution is taken in a standard test chamber of 30 m3 with a micro-syringe, placed in a micro-injection pump, and 48 injections are made within 48 h to simulate the sustained release of formaldehyde. Environment, finally collected 6 sets of test concentrations for data analysis, and also set a blank control group compared with Xinyi Xiaobai PRO.

After several injections of formaldehyde in accordance with national standards, the formaldehyde in the experimental chamber of the blank control group has been accumulating, and the concentration has increased. Finally, it has reached 0.26 mg/m3, which is 2.6 times higher than the standard! The concentration of formaldehyde is controlled within the national standard, and it is stably maintained at an ultra-low concentration of 0.02mg/m3!

In these two tests, whether it is low-level formaldehyde or sustained release of formaldehyde, whether in the most high-grade or silent file, Xinyi Xiaobai PRO can effectively remove formaldehyde pollution in the home improvement environment! Compared with conventional The detection method, which obviously reflects the true effect of the air purifier in addition to formaldehyde.
