1. Choose the right purchase channel
When buying an air purifier, it is recommended to buy it from formal channels such as large shopping malls, electrical appliances stores, brand stores, and mainstream e-commerce websites. Purchase an air purifier according to your actual needs.
The brand, function, performance, appearance design and price of air purifiers are very different, which is dazzling. Consumers are advised to choose products according to their actual needs, not that the more functions the better. For example, for consumers who need to protect against PM2.5, it is recommended to choose an air purifier with outstanding PM2.5 purification ability. Newly decorated homes can focus on air purifiers with outstanding capacity to remove formaldehyde and toluene.
2. Filtration technology
The particulate pollutant filtration technology is mainly HEPA filters. The quality of HEPA filters is uneven. Although some small brands of filters have higher filtration efficiency, they have high resistance, low energy efficiency ratio, and are easy to block and have a short lifespan. , It is generally recommended to use a deep dust-holding HEPA filter with electrostatic electret. The electrostatic electret technology makes the non-woven fiber have positive and negative charges, which can effectively capture the particles in the air. Many HEPA filters are known to have electrostatic electret technology. However, due to technical reasons, the electret charge of many filters will decay quickly in a relatively short period of time, resulting in reduced filtration efficiency. It is recommended to choose a 3M electrostatic electret HEPA filter, which uses the same electrostatic electret technology as the 3M mask to permanently ensure that the electret efficiency is not attenuated. High efficiency, low resistance, and large dust holding capacity are the last word!
3. Pay attention to the applicable area or particulate clean air volume (CADR)
The purification capacity of an air purifier is mainly determined by the applicable area and the amount of particulate clean air (CADR: the rate of clean air provided). The relationship between the two is: applicable area = CADR×0.1. The purification capacity of other pollutants should be combined with the applicable area.
4. Energy efficiency ratio and energy efficiency rating
Air purifiers are usually used continuously for a long time. Energy efficiency ratio, as an important indicator to measure the purification capacity and power consumption of air purifiers, deserves everyone's attention. The higher the energy efficiency ratio and energy efficiency level, the more energy-efficient the air purifier is and the lower the cost of use.
