Optional air purifier attention indicator air purifier

Air purifiers, I believe that everyone knows more or less. Nowadays, there are more than one thousand brands of air purifiers in the market, but it is a big problem for ordinary consumers to judge which air purifier is good. At this time, we need to understand the indicators of the purchase of air purifiers. Now there are many brands of air purifiers on the market, so let's introduce the brand of air purifiers.

Optional air purifier attention indicator

First, the fan air volume indicator. The air purifier with high efficiency filtration must ensure that the indoor air reaches a certain number of air changes, that is, the fan built in the air purifier has a certain amount of air. Under normal circumstances, for a house with a height of 3m and an area of about 20m2, it is best to buy an air purifier with a wind volume of about 60m3/h. This will achieve a true purification effect.

Second, the purification efficiency indicator. The National Standard for Purification Efficiency (CADR) values is the primary indicator for evaluating the performance of air purifiers. The higher the purification efficiency value, the larger the clean air output ratio of the air purifier, and the higher the purification efficiency of the purifier. Consumers in the purchase of air purifiers must look at the value of purification efficiency, consumers of general demand should choose products with CADR value above 120, the higher the purification efficiency value, the higher the purification efficiency of the purifier, such as If the indoor air quality has high requirements, it is necessary to select a product with a purification efficiency value of 200 or higher.

Third, the energy efficiency ratio indicator. The energy efficiency ratio is an important indicator for measuring the purifying performance and power consumption of air purifiers in the national air purifier standard. The higher the value, the more energy-saving the air purifier is. This indicator is in line with the green environmental protection concept. For an air purifier with a good energy efficiency ratio, the energy efficiency ratio should be greater than 3.5. However, pay attention to whether the selected purifier has a fan, because the air purifier with the fan has higher purification efficiency, and because of the need to consume energy, the energy efficiency is higher than that of the purifier without the fan installed.

Fourth, safety indicators. In addition to the safety indicators of general household appliances, an important safety indicator for air purifiers is the ozone safety indicator. Ozone has been proven to be related to health hazards in indoor air environments, and its concentration is strictly limited and strict Test method. Some air purifiers that use electrostatic cleaning, UV lamp disinfection, and negative ion generators may generate ozone during operation, and it is acceptable if the ozone indicator is controlled within a safe range.
