    Three highs and one low indicators of air purifiers are good.

    Since the frequent occurrence of haze weather in China, air purifiers have entered our social life, China's air purifier market has begun to develop by leaps and bounds, and more and more brands have been born.

    In order to regulate the air purifier market. Since September 15, 2015, China's "New National Standard for Air Purifiers" has been officially promulgated, and four core indicators have also been clarified. These are CADR (Clean Air Volume), CCM (Cumulative Purification Volume), Energy Efficiency Rating, and Noise Standards.

    A truly effective air purifier = high CADR value + high CCM value + high energy efficiency value + low noise value; The higher the CADR (clean air volume) value, the faster the purification efficiency and the larger the applicable area. The higher the CCM (cumulative purification capacity) value, the more pollutants are purified, and the longer the filter life; The higher the energy efficiency level, the more electricity saving. It is best when the CADR value, CCM value, and energy efficiency value of an air purifier are larger, and the noise is smaller within the specified range.

    However, some advice was made at the time of purchase: the most important thing for an air purifier is to replace the filter. If consumers cannot replace the filter in time during use, not only will there be no purification effect, but it may become the first of secondary pollution.

    Then there is the fact that the use of air purifiers for long periods of time will reduce the concentration of carbon dioxide, so it is still necessary to open windows for ventilation in non-severe smog weather.

    There are still many big brands in the Chinese market, because since the frequent haze weather in China in the past few years, many foreign and domestic businesses have shifted their centers to the air purifier industry. Also, there are other factors to consider when buying a product. According to a report by China.com, the indoor air pollution in newly renovated rooms is mainly formaldehyde, benzene, TVOC, etc., and you can buy products with a large amount of clean air and high energy efficiency.

    If there are sick people and children at home, you should also consider the performance of the air purifier to remove microorganisms when choosing a purifier, and the higher the sterilization rate, the better.

    With these indicators, you can indeed judge the quality of an air purifier, generally we test or judge through these, and then we must choose a big brand to choose the filter element, and then we often have to replace the new filter element.

    The lower the value on the air purifier, the better.

    Air purifiers can effectively improve the cleanliness of the air, and today's high-end air purifiers are equipped with a detector that digitally displays the amount of dust in micrograms.

    cubic meters, the lower the value, the smaller the value is stated, that is, the less dust and other substances in the air, so the lower the value, the better.

    The air purifier is very low when it is turned on, indicating that the indoor air quality is very good at that time. And the general air purifier display screen shows the value, so the value is very low, indicating that the median value of indoor air is very low, but it does not mean that there is no formaldehyde in the room, toluene, diformaldehyde, TVOC, bacteria, and viruses. The air-based cavity purifier also has more functions.

    We take the German Seiko Northenberg air fight air purifier as an example, the Northberg air purifier products are mainly for haze particles, formaldehyde, benzene, TVOC, bacteria, viruses, insect mites and other pollutants to purify, and some have humidification functions. Therefore, the value of the air purifier is very low after it is turned on, and it is recommended that you still need to use it continuously.
